For longer-duration or higher-energy transients, the clamping voltage rises above 214V; the datasheet derating curve shows the safe operating region across pulse width and repetition rate. The clamping performance holds across the temperature span, but the breakdown voltage drifts positive with temperature; the datasheet tempco curve is required for precision over-voltage set-points near 133V.","metaTitle":"1.5SMCJ120C TVS Diode, 120V Standoff, 214V Clamp","metaDescription":"Diotec 1.5SMCJ120C unidirectional TVS diode, 120V standoff, 214V clamping, 7A peak pulse, DO-214AB SMC package.
