The SM30T42AY is a unidirectional Zener TVS diode designed for automotive applications. It provides transient voltage protection with a peak pulse power rating of 3000W (3kW). The device has a reverse standoff voltage of 36V and a clamping voltage of 58.1V at a peak pulse current of 48.4A.
This TVS diode is housed in a DO-214AB (SMC) surface mount package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 175°C, making it robust for harsh environments. The part does not include power line protection and is intended for unidirectional protection of sensitive electronics.
Typical applications include automotive electronic control units, sensors, and other systems requiring reliable overvoltage protection. The SM30T42AY is RoHS3 compliant and has an MSL rating of 1 (unlimited).
