SM6T42CAY Description

Short technical summary and product information.

The SM6T42CAY is a bidirectional Zener-based transient voltage suppression (TVS) diode from STMicroelectronics designed for automotive applications. It provides robust protection against voltage transients with a reverse standoff voltage of 36V and a maximum clamping voltage of 76V at a peak pulse current of 52A (8/20µs). The device is rated for 600W peak pulse power dissipation.

 

This TVS diode is mounted in a surface-mount DO-214AA (SMB) package, enabling compact PCB designs. It operates over a wide temperature range from -55°C to 150°C, making it suitable for harsh environments. The device is bidirectional, protecting both positive and negative voltage transients.

 

The SM6T42CAY is specifically qualified for automotive applications and is compliant with RoHS3, REACH, and has an MSL rating of 1 (unlimited). It is ideal for protecting sensitive electronics in automotive control units, infotainment systems, and other 36V power supply lines.
