SM30T47CAY ST Transient Voltage Suppressors (TVS)

The SM30T47CAY is an automotive-grade (AEC-Q101) 3000W bidirectional Transil TVS diode from STMicroelectronics in SMC (DO-214AB) surface-mount package, featuring 40V reverse standoff voltage for protecting sensitive automotive circuits against load dump surges . For selection, verify reverse standoff voltage of 40V, breakdown voltage of 44.4V minimum, clamping voltage of 64.5V at 43.5A peak pulse current, peak pulse power of 3000W (3kW) for 10/1000µs waveform, and operating junction temperature from -55°C to +175°C. Features include AEC-Q101 qualification for high reliability, compliance with ISO 7637-2 load dump protection standards, bidirectional configuration for AC or bipolar signal lines. Ideal for automotive electronic control units, sensor protection, infotainment systems, body control modules, 48V power distribution systems, and any high-reliability application requiring 3kW bidirectional transient suppression.
