When a surge exceeds the 58.9 V breakdown threshold the device snaps into conduction and clamps the peak at 85 V; the 18 A peak pulse current is the event size the clamping table is indexed to. A larger surge (say 30-40 A) will produce a higher clamping voltage following the VI curve — the datasheet IV characteristic is the document to size against the specific transient waveform in the end equipment. ## Thermal and package integration On the board, the SMC (DO-214AB) package dissipates the clamped surge energy through the cathode tab into the copper pad; adequate pad area is the board-level thermal lever, not the package itself. The surface-mount Tape & Reel orientation suits automated pick-and-place on high-density telecom line cards. Unidirectional only — it protects against positive transients relative to ground. Bidirectional protection requires a different topology (two antiparallel unidirectional devices or a genuine bidirectional TVS).","metaTitle":"1.5SMC62A V7G TVS Diode, 1.5kW, DO-214AB SMC","metaDescription":"Taiwan Semiconductor 1.5SMC62A V7G unidirectional Zener TVS, 53V standoff, 85V clamping, 1.5kW peak pulse, DO-214AB SMC.
