SM8S30AHE3_A/I Description

Short technical summary and product information.

The Vishay Dale SM8S30AHE3_A/I is a surface mount Transient Voltage Suppressor (TVS) diode from the PAR® series. It is designed for high reliability and automotive requirements, offering protection against voltage transients.

Key electrical specifications include a 30V working voltage (VWM) and a breakdown voltage (VBR) ranging from 11.1V to 52.8V. The device provides a clamping voltage (VC) of 48.4V at a peak pulse current (IPP) of 136A. It can handle a peak pulse power dissipation of 6600W for a 10 x 1000 µs waveform and 5200W for a 10 x 10000 µs waveform. Power dissipation on an infinite heatsink is rated at 8W.

This TVS diode operates within a wide temperature range of -55°C to +175°C. It is housed in a DO-218AB package, suitable for surface mounting. The device is AEC-Q101 qualified and meets MSL level 1 standards.
