SM15T47CAY Description

Short technical summary and product information.

The SM15T47CAY is a bidirectional Zener TVS diode designed for automotive applications. It provides transient voltage protection with a reverse standoff voltage of 40.2V and a minimum breakdown voltage of 44.7V. The device can clamp transients up to 84V at a peak pulse current of 119A (8/20µs waveform) and handle 1500W of peak pulse power. It is not intended for power line protection. The diode is surface-mount packaged in a DO-214AB (SMC) case, suitable for automated assembly. Operating temperature range is -40°C to 150°C. The part is RoHS3 compliant and has MSL 1 unlimited moisture sensitivity level.
