The SM30T15AY is a unidirectional Zener TVS diode from STMicroelectronics designed for transient voltage suppression. It features a reverse standoff voltage of 13V and a clamping voltage of 21.5V at a peak pulse current of 140A. The device can handle 3000W of peak pulse power (10/1000µs waveform), making it suitable for high-energy transient protection.
This automotive-grade component operates over a junction temperature range of -55°C to 175°C and is supplied in a surface-mount DO-214AB (SMC) package. It has one unidirectional channel and does not provide power line protection. The Zener technology ensures fast response and reliable clamping.
Typical applications include automotive electronic control units, sensors, and infotainment systems requiring robust ESD and surge protection. The compact SMC package enables efficient PCB layout.
