That 80.3V ceiling is what the downstream silicon sees — keep it below the absolute max of your DC-DC converter or load switch. ## Breakdown, clamping, and the operating envelope Breakdown voltage starts at 50V min, so a 45V rail sits comfortably below the knee. The device is bidirectional — one part handles both positive and negative transients, saving a diode on the board.","metaTitle":"SMCJ45CE3/TR13 Zener TVS Diode 1.5kW 45V DO-214AB –","metaDescription":"SMCJ45CE3/TR13 Microchip Zener TVS, 1500W peak pulse, 45V reverse standoff, 80.3V clamp.

If your rail sees only positive transients, the unidirectional part works.
