The SM4T82AY is a Zener-based unidirectional transient voltage suppression (TVS) diode from STMicroelectronics, designed for automotive applications. It provides protection against overvoltage transients with a reverse standoff voltage of 70V and a maximum clamping voltage of 146V at a peak pulse current of 16A (8/20µs waveform). With a peak pulse power rating of 400W, it can handle high-energy surges.
This TVS diode is housed in a surface-mount SMA (DO-214AC) package, making it suitable for compact designs. It operates over a wide temperature range of -55°C to 150°C, ensuring reliability in harsh environments. The device is rated for automotive use, though power line protection is not specified.
Note: The RoHS compliance status is unverified, and the manufacturer page was inaccessible. Cross-reference part numbers for DigiKey are available for sourcing.
