The unidirectional channel (single diode) clamps positive transients above the breakdown threshold; for AC or bidirectional protection you would need two devices or the bidirectional variant. The 10.9 A peak pulse current at the 10/1000 µs test condition confirms the diode can handle the full 1500 W without exceeding the clamping voltage. ## Breakdown and clamping window — where the protection sits Reverse standoff voltage is 85.5 V — the diode does not conduct below that, so it stays invisible to the protected rail during normal operation. Breakdown starts at 95 V minimum, and the clamping voltage at peak pulse current is 137 V maximum. That 42 V window between standoff and clamp is the voltage excursion the load must survive; a 100 V-rated MOSFET on the rail has margin. Operating temperature spans -65°C to 150°C (junction), which covers cold-start in outdoor telecom cabinets and the self-heating from repetitive surges. The DO-214AB (SMC) package with a copper pad area under the cathode tab sets the thermal resistance; the 1500 W rating assumes the board layout follows the recommended land pattern. ## Active production — no end-of-life watch needed The base product number is 1.5SMC100; the -M3/57T suffix denotes the packaging (Tape & Reel) and the Vishay Green/ RoHS-compliant plating.","metaTitle":"Vishay 1.5SMC100A-M3/57T TVS, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC100A-M3/57T Zener TVS diode, 1500W peak pulse, 85.5V standoff, DO-214AB.
