81 V standoff, 144 V clamp — the clamping margin matters
The 1.5SMC100H: Its 81 V reverse standoff voltage protects a 72 V nominal rail, while the 144 V maximum clamp at 10.9 A peak pulse current defines the voltage a downstream 100 V-rated MOSFET must survive during a surge event.
AEC-Q101 — the full automotive temperature band with PPAP
AEC-Q101 qualified, the 1.5SMC100H covers the -55°C to 150°C junction temperature range — every under-hood or engine-bay location within the automotive temperature envelope, with PPAP documentation that satisfies an OEM auditor. The Automotive grade designation means this part is screened for the reliability stresses of a vehicle's lifetime, not just an industrial surge requirement.
Active production — no NRND or EOL flag
Taiwan Semiconductor Corporation's base product number 1.5SMC100 covers the family; the H suffix denotes the automotive-qualified variant.
DO-214AB (SMC) — the larger body for 1.5 kW dissipation
Supplied on Tape & Reel (TR), it suits high-volume pick-and-place assembly for telecom or automotive ECU lines.
