Power supply is widely used in automotive electronics, industrial control, communications security and other important areas, power supply as the "heart" of electronic products, it can be stable and reliable operation, directly determines the ultimate reliability of the product, the actual application of long-distance transmission, complex electromagnetic environment, resulting in the equipment and easy to suffer from static electricity or other inductive Over-voltage and other conditions and damage. Therefore, anti-static surge impact is an important part of the circuit design is essential.

SOCAY Electronics introduced SM2KBF40CA is a surge protection device that can be used for low-voltage DC power supply.The device adopts the SMBF small package, the volume is relatively small but the power is large, bi-directional non-polarity distinction, the comprehensive protection ability is much higher than the same volume of products, can effectively reduce the design cost.

With low clamping voltage, clamping voltage of 75V; reverse leakage current Ir <1uA, fast response <1ps, can be used for low-voltage DC power supply for accurate surge protection.

High environmental adaptability, operating temperature range of -55 °C~ +150 °C.
