SM4T50CAY Description

Short technical summary and product information.

The SM4T50CAY is a Zener-type bidirectional TVS diode from STMicroelectronics designed for automotive applications. It provides transient voltage protection with a reverse stand-off voltage of 43V and a clamping voltage of 91V. The device can handle peak pulse currents up to 25A (8/20µs) and delivers 400W of peak pulse power.

 

This TVS diode is housed in a surface-mount DO-214AC (SMA) package and operates over a temperature range of -55°C to 150°C. It is suitable for protecting sensitive electronics from voltage transients in automotive environments.

 

The SM4T50CAY is RoHS3 compliant and REACH unaffected, with an MSL rating of Level 1 (unlimited). It is a single-channel bidirectional device and does not include power line protection.
