The SM15T56AY is a unidirectional TVS diode from STMicroelectronics designed for automotive applications. It offers a reverse standoff voltage of 48V and a maximum clamping voltage of 100V at a peak pulse current of 100A (8/20µs). The device can handle 1500W of peak pulse power, providing robust transient voltage suppression.
With a single unidirectional channel, the SM15T56AY is optimized for protecting sensitive electronics on 48V nominal power lines. Its Zener-based clamping technology ensures fast response to overvoltage events.
The diode is housed in a surface-mount DO-214AB (SMC) package, suitable for automated assembly. It operates over a junction temperature range of -40°C to 150°C and is rated for automotive environments.
