That 45.7 V ceiling is what the downstream circuitry must survive; a 28 V-rated capacitor or IC with 50 V abs-max has comfortable margin. Rated for a 10/1000 µs exponential waveform, the 32.8 A peak pulse current is the maximum the diode can repeatedly handle without degradation. The operating temperature range of -65°C to 150°C covers military and industrial thermal profiles — no derating needed for most outdoor or engine-bay enclosures. ## Package and board-fit for DO-214AB Supplied on Tape & Reel, the 1.5SMC33A-M3/57T is ready for automated pick-and-place.","metaTitle":"Vishay 1.5SMC33A-M3/57T TVS Diode, 1500W, 28.2V Standoff","metaDescription":"Vishay 1.5SMC33A-M3/57T Zener TVS diode, 1500W peak pulse power, 28.2V reverse standoff, 45.7V clamp.
