Rated for 1500W (1.5kW) peak pulse power per the 10/1000µs waveform, this part handles moderate industrial surge events. The single unidirectional channel means the cathode connects to the protected rail and the anode to ground — not for AC line or bidirectional clamping applications. ## Temperature range and package: where it fits on the board","metaTitle":"SMCJ33AE3/TR13 TVS Diode – Microchip, 33V Standoff, 1.5kW","metaDescription":"SMCJ33AE3/TR13 Zener TVS, 33V reverse standoff, 36.7V breakdown min, 53.3V clamp, 1.5kW peak pulse, unidirectional, DO-214AB.
