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.

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.
