The SM30T10CAY is an automotive-grade bidirectional TVS diode from STMicroelectronics. It provides transient voltage suppression for sensitive electronics in automotive systems. Key electrical characteristics include a typical reverse standoff voltage of 8.5 V, a minimum breakdown voltage of 9.5 V, and a maximum clamping voltage of 14.4 V at 208 A peak pulse current (10/1000µs waveform). The device can handle 3000 W of peak pulse power, making it suitable for high-energy transients. It does not include power line protection. The SM30T10CAY is housed in a surface-mount DO-214AB (SMC) package, suitable for automated assembly. It operates over a wide temperature range of -55°C to 175°C. Compliance with RoHS, REACH, and MSL level 1 is indicated but unverified. This diode is cross-referenced with DigiKey part numbers 497-15398-2-ND, 497-15398-1-ND, and 497-15398-6-ND.
