SMA6T82AY Description

Short technical summary and product information.

The SMA6T82AY is a 600W peak pulse power Zener TVS diode designed by STMicroelectronics for automotive applications. It features a reverse standoff voltage of 70V and a clamping voltage of 120V, providing robust transient voltage protection for sensitive electronics. The device can handle a peak pulse current of 27A under an 8/20µs waveform.

 

This unidirectional TVS diode is housed in a compact DO-214AC (SMA) surface-mount package, making it suitable for space-constrained designs. It operates over a wide temperature range from -40°C to 150°C (junction), ensuring reliable performance in harsh automotive environments. The component is RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited).

 

Designed for automotive electronics, the SMA6T82AY is ideal for protecting power lines, control modules, and sensor interfaces from voltage transients and ESD events. Its Zener technology provides precise clamping characteristics, while the surface-mount package facilitates automated assembly and high-volume production.
