The SM30T23AY is a unidirectional TVS diode designed by STMicroelectronics for automotive applications. It features a reverse standoff voltage of 20V and a clamping voltage of 32.4V, providing robust transient voltage suppression. With a peak pulse power rating of 3000W (3kW) and a peak pulse current of 92.6A, this device can handle high-energy surges.
This TVS diode is housed in a DO-214AB (SMC) surface-mount package, suitable for automated assembly. It operates over a wide temperature range from -55°C to 175°C, making it reliable in harsh automotive environments. The part is RoHS3 compliant and REACH unaffected.
Designed for automotive electronics, the SM30T23AY is ideal for protecting sensitive circuits from voltage transients induced by load dump, inductive switching, and ESD events. Its unidirectional configuration is optimized for DC power line protection in vehicles.
