The 70.1V reverse standoff is the working rail voltage the TVS must never exceed continuously; anything above that and the part enters its avalanche region. When a surge does arrive, the breakdown threshold is 77.9V minimum — that is where the device turns on and begins clamping. The tighter that standoff-to-clamping window, the less overvoltage the protected load actually sees — on a 48V rail with reasonable margin this part lands squarely in the useful zone. ## DO-214AB SMC package — surface-mount surge protection on the rail The DO-214AB (SMC) package is the standard SMCJ footprint, meaning it drops into any board using the industry-standard land pattern without a layout spin — and it mounts flush to the PCB for thermal spreading through the pad. Operating junction temperature runs to 150°C, which gives plenty of headroom above most board-level ambient ratings; the -65°C low end covers cold-start and outdoor deployments. Confirm reel quantity and full lot traceability at RFQ before committing to a repair run.","metaTitle":"1.5SMC82CA-E3/9AT TVS Diode, 1500W, 70.1V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC82CA-E3/9AT bidirectional TVS diode, 1500W peak pulse at 10/1000µs, 70.1V standoff, 113V clamping.
