Vishay 15SMC400AHM3BH Surface Mount Transzorb

The Vishay 1.5SMC400AHM3_B/H is a surface mount Transient Voltage Suppressor (TVS) within the 1.5SMC series. This device is engineered to provide reliable protection against voltage transients induced by inductive load switching and lightning surges in sensitive electronics. Its low profile package and glass passivated chip junction contribute to excellent clamping capability and a fast response time. The SMC (DO-214AB) package is ideal for automated placement, and the AEC-Q101 qualified option makes it suitable for automotive applications. It is commonly used in consumer, computer, industrial, automotive, and telecommunication applications to safeguard ICs, MOSFETs, and signal lines.
