The SM8S33ATHE3/I is a unidirectional transient voltage suppressor (TVS) diode from Vishay General Semiconductor, designed for protecting sensitive electronics from voltage transients. It is part of the SM8SxxAT series and is AEC-Q101 qualified for automotive applications.
With a standoff voltage of 33V and a breakdown voltage range of 36.8V to 40.8V, it clamps transients to a maximum of 53.3V at a peak pulse current of 124A (10/1000μs waveform). It can handle 6600W peak pulse power (10/1000μs) and 5200W (10/10000μs). The device also features a peak forward surge current of 700A (8.3ms) and a power dissipation of 8W on infinite heatsink.
The diode is housed in a DO-218AC surface-mount package with matte tin plated leads. It operates over a junction temperature range of -55°C to 175°C and meets MSL level 1. The molding compound is UL 94 V-0 rated.
Typical applications include automotive load dump protection, inductive load switching, and lighting surge protection. It is RoHS-compliant and REACH unaffected.
