The SM15T18CAY is a single bidirectional Zener TVS diode from STMicroelectronics designed for automotive applications. It offers a reverse standoff voltage of 15.3V and clamps transients to a maximum of 32.5V. With a peak pulse power rating of 1500W and a peak pulse current of 308A (8/20µs), this device provides robust protection against voltage surges.
This TVS diode is surface mounted in a DO-214AB (SMC) package, suitable for automated assembly. It operates over a wide temperature range of -40°C to 150°C. The part is not intended for power line protection; it is optimized for signal line transient suppression in automotive electronics.
The SM15T18CAY is listed as RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited), though these compliance statuses are unverified from source documents. No datasheet is currently linked.
