1500 W peak pulse, 85.5 V standoff — board-level transient clamp
The 1.5SMC100CA TR13 PBFREE: It operates across -65°C to 150°C junction temperature, covering the full industrial and automotive under-hood thermal envelope — no derating worry for a board that sees 125°C ambient. Housed in the DO-214AB (SMC) surface-mount package, it fits standard pick-and-place reflow and mates with the common SMC footprint used across the 1.5SMC series.
When a transient hits, the device clamps at 137 V maximum (at 11 A peak pulse), which means any downstream component rated for at least 150 V will survive the surge — common for 100 V MOSFETs or 120 V-rated capacitors on a 48 V bus. The 1500 W peak pulse rating (10/1000 µs) is the energy-handling benchmark for this package class — it absorbs a 1 ms surge without exceeding the junction temperature limit, making it suitable for secondary protection on telecom or industrial DC supplies.
