SM6F31AY Description

Short technical summary and product information.

The SM6F31AY is a 600W peak pulse power Zener TVS diode designed for automotive applications. It features a reverse standoff voltage of 31V and a maximum clamping voltage of 65V at a peak pulse current of 61A (8/20µs waveform). This unidirectional device provides robust transient voltage protection for sensitive electronics in automotive environments.

 

The device is housed in a surface-mount SOD-128 package (supplier device package SOD128Flat) and operates over a junction temperature range of -55°C to 175°C. It is not intended for power line protection, making it suitable for signal line and low-voltage bus protection in automotive systems.
