Its 34.2 V minimum breakdown voltage ensures the device starts conducting before the protected circuitry sees damaging overvoltage, while the 64.3 V maximum clamping voltage at the rated 156 A peak pulse current (8/20 µs waveform) limits the let-through energy. ## 1500 W peak pulse — sizing the protection budget For a 30.8 V rail, this translates to a clamp that can handle substantial surge energy without failing short or open. The 156 A peak pulse current at 8/20 µs gives a quick reference for lightning-surge or ESD scenarios common in outdoor telecom and industrial I/O lines. The SMC body provides adequate copper area for heat sinking during the pulse — ensure the PCB land pattern follows the recommended dimensions to keep the thermal impedance low. No special bake or MSL handling beyond standard moisture-sensitive-device precautions is indicated.","metaTitle":"SM15T36A STMicroelectronics TVS Diode, 1500W, DO-214AB","metaDescription":"STMicroelectronics SM15T36A TRANSIL™ TVS diode: 1500W peak pulse power, 34.2V min breakdown, 30.8V standoff, DO-214AB SMC.

Both share the same 1500 W peak pulse power and 30.8 V standoff voltage, but the 'A' suffix indicates a single-direction clamp, while the non-'A' variant clamps in both directions.
