DA53 | Power Surge Absorber
Contributes to reducing the risk of failure by balancing AC withstand testing and surge protection.
"I want to satisfy the AC withstand voltage test. However, I want to ensure that the equipment is reliably protected from lightning surges." Are you struggling with such conflicting requirements in power supply design? The DA53 is a surge absorber for power supplies that supports both compliance with AC withstand voltage tests and high surge protection performance. With a rich lineup of operating voltage options, optimal selection can be made according to circuit conditions. Furthermore, its excellent responsiveness due to the micro-gap discharge method and a surge withstand capability of 3,000A allows it to meet test conditions of IEC61000-4-5 Level 4 and above. This contributes to achieving compliance with standards, reducing the risk of failure due to lightning surges, and decreasing evaluation and design workload. It supports the development of safer and more reliable products in power circuits for servers, air conditioning equipment, automotive devices, and more.
