The 1.5 kW peak pulse rating describes what the diode survives once, not a continuous dissipation number — for repetitive transients, derate per the manufacturer's surge-repetitions curve in the datasheet. ## DO-214AB package and unidirectional topology The DO-214AB (SMC) is the larger-jaw SMC variant — the cathode band marks the anode-cathode polarity on unidirectional parts, which means this part clips positive transients only; it does not protect against negative-going spikes. Surface-mount terminations on the SMCJ-equivalent foot print require a proper thermal pad footprint at the cathode tab for heat sinking during clamping events — the Tj rating of 150°C is measured at the junction, so the board-level thermal path matters. ## Sourcing posture — Active lifecycle No compliance certifications (UL, CSA, IEC) are listed in this product record — confirm any regulatory requirements against the full Vishay datasheet and request the CofC before specifying this part in safety-critical or cert-required designs.","metaTitle":"Vishay 1.5SMC68A-E3/57T TVS Diode, 92V Clamping, 1.5 kW","metaDescription":"Vishay 1.5SMC68A-E3/57T unidirectional Zener/TVS diode, 58.1V standoff, 92V clamping, 1.5 kW peak pulse at 16.3A (10/1000µs).
