1500W peak pulse power, 85.5V standoff — the TVS that clamps at 137V
The 1.5SMC100A_R1_00001: The 137V clamp ceiling means this part protects 85.5V rails from transients that would otherwise punch through downstream silicon — a 100V-rated MOSFET on the same rail sees a 37V margin at the clamp point, which is the difference between surviving a surge and failing short.
DO-214AB SMC package — surface-mount, single-channel, wide-temperature
Housed in a DO-214AB (SMC) surface-mount package, this is a single unidirectional channel device. The SMC footprint is a standard JEDEC outline — the same land pattern serves the full 1.5SMC family, so a BOM that already uses a 1.5SMCxxxA part reuses the same PCB layout. No power line protection is built in; this is a data-line or DC-rail TVS, not a mains-side suppressor.
Active production — no end-of-life watch needed
Panjit lists the 1.5SMC100A_R1_00001 as Active in its current lifecycle status. Supplied in Tape & Reel (TR) and Cut Tape (CT) packaging, the reels are standard for pick-and-place assembly. Store the reels dry — the DO-214AB body is not moisture-sensitive per JEDEC Level 1, but the tape and reel packaging benefits from a controlled environment to avoid oxidation on the solder pads over long shelf storage.
