SM4T7V6AY Description

Short technical summary and product information.

The SM4T7V6AY is a 400W automotive-grade Zener TVS diode from STMicroelectronics. It features a reverse standoff voltage (VRWM) of 6.5V and a clamping voltage (VC) of 14.5V at a peak pulse current (IPP) of 160A (8/20µs waveform). With a single unidirectional channel, it provides transient voltage protection for sensitive circuits.

 

Designed for surface mount assembly, the SM4T7V6AY is housed in a DO-214AC (SMA) package. It offers a wide operating temperature range from -55°C to 150°C (TJ), making it suitable for harsh automotive environments. The component does not include power line protection, indicating it is intended for signal or data line protection.

 

STMicroelectronics' SM4T7V6AY is listed as RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited floor life). It is a reliable choice for automotive applications requiring robust ESD and surge protection.
