What the 1.5SMCJ36C protects — and how
A 36V standoff means the protected rail can sit at or below 36V DC without the TVS conducting — the margin between standoff and breakdown gives the circuit headroom under normal operation. Power line protection is not listed, so this part guards individual signal or load lines — not a bus-level protection role. The unidirectional polarity means it clamps positive transients only; a bidirectional TVS is needed if the protected node sees both polarities.
Package and field-replaceability notes
DO-214AB (SMC) is the industry-standard surface-mount package for 1.5 kW TVS diodes — the footprint is shared across multiple manufacturers, so swapping in a second-source alternative on the same PCB layout is straightforward where pinout allows. Junction temperature rating is -50°C to 150°C, giving wide margin for transient self-heating during clamping events and for deployment in thermally hostile environments without derating concerns at the component level. Packaged as strip, not on reel — confirm your pick-and-place system accepts cut-tape or loose-piece feeding if you are kitting for production assembly, since reel-sourced parts from some distribution channels may require repackaging.
