SM6F12AY Description

Short technical summary and product information.

The SM6F12AY is a 600W transient voltage suppression (TVS) diode designed by STMicroelectronics for automotive applications. It provides unidirectional protection with a clamping voltage of 25.3V and can handle peak pulse currents up to 157A under an 8/20µs waveform. The device operates over a wide junction temperature range of -55°C to 175°C, making it suitable for harsh automotive environments.

 

This TVS diode is housed in a compact SOD-128 package with a SOD128Flat supplier device package, enabling surface mount assembly for space-constrained designs. It is not intended for power line protection but is optimized for signal and data line transient suppression in automotive electronics.

 

The SM6F12AY is RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited), ensuring reliable performance and ease of handling during manufacturing. Its automotive qualification makes it ideal for use in engine control units, infotainment systems, and other vehicle electronics requiring robust ESD and surge protection.
