The 77.8 V reverse standoff sits below the 86.5 V minimum breakdown, giving the diode headroom to stay off during normal circuit operation and snap into conduction on a transient — the three-voltage selection logic every TVS designer works through. ## Wide Tj range for stressed environments Operating junction temperature runs -55°C to 150°C — the upper bound is the key differentiator from commercial-grade 1.5SMC variants. A TVS specified to 150°C Tj holds its clamping characteristics under repeated transient stress without the derating curves eating into the design margin. If the end equipment is automotive or industrial-safety-rated, confirm the qualification matrix against the Panjit datasheet before committing the BOM line. ## SMC package and reel format for production assembly DO-214AB (SMC) is the standard industry footprint for this power class — the cathode band on the body marks polarity on the unidirectional device, which is non-negotiable for correct reverse-bias clamping orientation. Tape-and-reel packaging is listed alongside cut-tape; reel quantities align with standard SMC assembly pitch — verify the EIA-481 carrier tape dimensions against the pick-and-place feeder width before scheduling production.","metaTitle":"Panjit 1.5SMC91A_R1_00001, 125V Zener TVS, 1.5kW","metaDescription":"Zener TVS diode, 77.8 V standoff / 125 V clamping, 1.5 kW peak pulse, -55°C to 150°C Tj.
