That 103 V ceiling is what your downstream ICs must survive — the tighter the clamp, the less margin your protected circuitry needs. Rated 1500 W peak pulse — that is the 1.5 kW the series name carries, measured on the 10/1000 µs surge curve. ## Temperature range and the unidirectional Zener mechanism The upper limit is specified as TJ (junction), not ambient — the board thermal design determines whether the part actually runs near that ceiling. One unidirectional channel means it handles one polarity only. For a 75 V nominal rail this is standard — positive transients are clamped, negative excursions are forward-biased through the Zener knee. If the line needs bipolar protection a second opposite-polarity TVS is added. ## DO-214AB SMC footprint and reel packaging DO-214AB (SMC) is the standard 1.5 kW TVS land pattern — wide adoption means the footprint is compatible across manufacturers. The part ships on Tape & Reel or Cut Tape, which covers both production run and prototype quantities without minimum order quantity friction. Surface-mount termination — no through-hole mounting. The SMC flat-body profile sits flush on the pad; reflow profile must stay below the junction temperature limit, so a thermocouple at the case during profiling is the standard qualification step for the first board spin. ## Active status and sourcing posture The 1.5SMC series covers 10 V through 440 V standoff in the same SMC package, so second-source options at 75 V exist from multiple manufacturers in the same footprint.","metaTitle":"Panjit 1.5SMC75A_R1_00001, 75V TVS Diode, 1.5kW SMC","metaDescription":"Panjit 1.5SMC75A_R1_00001 unidirectional TVS Zener, 64.1V standoff, 103V clamping, DO-214AB SMC.
