The SM30T12AY is a unidirectional Zener TVS diode designed for overvoltage protection in automotive applications. It offers a peak pulse power dissipation of 3000W (3kW) and a peak pulse current of 176A at 17V clamping voltage.
The device has a reverse standoff voltage of 10V and is not intended for power line protection. It operates over a wide temperature range from -55°C to 175°C, suitable for harsh automotive environments.
The SM30T12AY is housed in a DO-214AB (SMC) surface-mount package, enabling automated assembly and compact PCB layouts. Its single-channel unidirectional configuration is ideal for protecting sensitive circuits on 10V rails.
