The SM30T10AY is a unidirectional Zener TVS diode manufactured by STMicroelectronics. It is designed to protect sensitive electronics from voltage transients by clamping overvoltage events. With a reverse standoff voltage of 8.5V and a maximum clamping voltage of 14.4V at 208A peak pulse current, it provides robust protection for 3.3V or 5V logic lines in automotive environments. The device can handle 3000W of peak pulse power (10/1000µs waveform), ensuring reliable operation under transient conditions. It is not power line protected, making it suitable for signal lines. The SM30T10AY is surface mountable in a DO-214AB (SMC) package, with an operating temperature range of -55°C to 175°C. It is listed as RoHS3 compliant, REACH unaffected, and MSL 1 (unlimited), though these certifications are unverified. This TVS diode is ideal for automotive applications requiring high surge capability and compact footprint.
