Constant Current Diode "CRD S Series (SMD Type)"

Constant Current Diode "CRD S Series (SMD Type)"

Low mounting height with resin package products! Ideal for LEDs too!

The CRD S series is a resin-sealed SMD package product for surface mounting. It has a lower mounting height than standard packages, allowing for the installation of thin LEDs without obstructing light. Additionally, we have added the "S-223T (22mA)" for high-brightness LEDs. Previously, the series had an upper limit of "S-183T (18mA)," which required the use of multiple components for 20mA high-brightness LEDs. However, with the "S-223T (22mA)," it is now possible to supply a constant current with a single component.

Production control, data diode for factory monitoring IoT OWCD3i

Production control, data diode for factory monitoring IoT OWCD3i

OWCD3, which comes bundled with a data conversion and decoding computer for OWCD2, has a model that is packaged in a 1U rack mount case!

The OWCD, which has received high praise, is provided from an air gap based on the premise of utilizing your existing assets, while other companies sell it alongside computers that perform data proxy and conversion decoding. However, when collecting and transmitting data as IoT, there is a desire to install everything at once in a compact size, especially when flowing data from OT to IT or when wanting to add to existing complex systems. To address this, we have launched the 3"i," which integrates the OWCD2 and a computer for signal conversion and decoding, allowing for easy incorporation into the network. However, this model does not offer particularly high performance and has not fully met various needs. Therefore, we have renewed it. Additionally, for customers who find the previous model insufficient for IoT purposes, we will also provide the -G"i." This will enable the promotion of data visualization within completely independent production equipment networks, ensuring security while actively improving yield rates, quality, and condition monitoring. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.

[Information] Shirutoku Report No. 12 #Types and Features of Diodes

[Information] Shirutoku Report No. 12 #Types and Features of Diodes

Efficient power supply using SiC devices! A brief introduction to the types and features of diodes.

★★Shirutoku Report: Useful Information You Can Benefit From★★ By switching semiconductor materials from Si to SiC (silicon carbide), the breakdown voltage of Schottky Barrier Diodes (SBD) has improved, making them usable in DC/DC converters for PCS. While using SiC enhances performance, cost issues had previously hindered its adoption. However, in the past year or two, cost challenges have improved, leading to an increase in usage opportunities. This report will briefly explain the types and characteristics of diodes.

12A reverse current prevention diode

12A reverse current prevention diode

Solar power generation reverse flow prevention, 12A, compatible with 1,000Vdc, 100 hours salt spray test passed, IP67.

It was developed to prevent reverse current caused by voltage differences between solar cell strings. By adopting an aluminum housing, we achieved high heat dissipation and waterproof performance. By removing the reverse current prevention diode from the junction box, we not only reduced the size of the junction box but also lowered its temperature. The aluminum housing enhances heat dissipation by being mounted on a metal frame, making it possible to maintain the diode's operating temperature at a low level.

Small High Brightness Direct Mountable Chip Series

Small High Brightness Direct Mountable Chip Series

A small high-brightness LED package that enhances the design flexibility of lighting fixtures and creates new lighting environments.

The biggest feature of the LED for lighting, the "Direct Mountable Chip," is its structure that incorporates a special "reflective wall" on the side of the LED chip, which efficiently reflects the light generated within the package to the top surface of the package. By minimizing the light emission component in the package side direction, it is possible to reduce the crosstalk phenomenon (light attenuation and color change caused by adjacent LED products) that occurs when multiple CSPs are densely mounted. This technology enables the realization of lighting fixtures that achieve both high luminous flux density and high light extraction efficiency, which were difficult to achieve with conventional CSPs, in various lighting application products. Additionally, the "Monochrome Color Direct Mountable Chip" realizes blue, green, orange, and red emissions based on the technology we have developed for blue chips and phosphors. All colors, including white, have a unified forward voltage (Vf), contributing to the simplification of electrical circuit design. *For more details, please refer to the PDF materials or feel free to contact us.*

Constant Current Diode "CRD E Series (Axial Lead Type)"

Constant Current Diode "CRD E Series (Axial Lead Type)"

High reliability with airtight sealing!

The "CRD E Series" uses elements that provide stable constant current characteristics in a compact size. It is a small device that employs a DO-35 style DHD (Double Heatsink Diode) structure with a DO35 (300mW) package. With hermetic sealing for high reliability, the component materials are inexpensive and excellent for mass production. Previously, the series had a maximum of "E-153 (15mA)," but "E-183 (18mA)" has been added. This allows for the supply of a constant current that does not exceed the rated current, making it possible to stabilize the brightness of high-brightness LEDs rated at 20mA with a single component.

Tohoku University Technology: The technology to improve tunnnel diode rectification performance : T22-255

Tohoku University Technology: The technology to improve tunnnel diode rectification performance : T22-255

Introducing a nanoparticle layer into MIM tunnel diodes to significantly improve rectification performance!

・Metal/insulator/metal tunnel diodes (MIM tunnel diodes) are used when rectifying signals of frequencies in the infrared and terahertz regions. ・ However, it is difficult to improve the rectification performance because there is a trade-off between electrical resistance and asymmetry. ・ The invention has solved the above issue by introducing metallic nanoparticle layers (NPs) into the MIM tunnel diodes and changing the tunnel barrier at forward and backward biases by the effect of electric field concentration. ・ Since the invention has greatly improved rectifying performance compared to tunnel diodes without NPs,the present tunnel diodes can be expected to be used to high-frequency devices (Optical rectenna, IR, THz detector).

OWCD Remote Maintenance Security Enhancement Solution

OWCD Remote Maintenance Security Enhancement Solution

In core important systems and OT, zero-day response is also essential. Let's enhance the effectiveness of security measures against attacks by implementing precise boundary control.

The Data Diode is a system that only allows information to be transmitted to core systems/data while ensuring that external communications are effectively blocked. However, what if bidirectional communication is necessary...? What about remote maintenance? In recent times, with the increase of "hard-to-detect attacks," measures that prioritize "preventing actual damage" are also important, such as ensuring that even if an intrusion occurs, data cannot be exfiltrated. That said, simply strengthening access authentication often takes time to close security holes. If you are only using a VPN, and cannot operate the system until the holes are patched, your work will be sacrificed. Therefore, a reliable protection mechanism is essential for core infrastructure and production equipment. In such cases, the <OWCD Solution> based on the Data Diode can be helpful. By enhancing the security effectiveness during remote maintenance, we provide ideas that can be utilized at key points in the pursuit of zero trust integrity! There are also increasing examples of integration into systems built by SIers. Please make use of it. There is an explanatory video at the related link below! This technology is patented by Mitsubishi Heavy Industries, Ltd.
