1500 W peak pulse in a DO-214AB footprint
The 1.5SMC100CAHM3/H is a 1500 W (1.5 kW) bidirectional TransZorb® TVS diode in the DO-214AB (SMC) package, part of Vishay's automotive-grade 1.5SMC series qualified to AEC-Q101. The bidirectional channel means a single device protects both polarities on a signal or power rail — useful for AC-coupled lines or where the return path is not ground-referenced. The 1500 W rating at the standard 10/1000 µs pulse gives a derating baseline for shorter or longer transients.
Automotive-grade clamp for harsh environments
The DO-214AB (SMC) footprint is a standard JEDEC outline shared across the 1.5SMC family — the same board layout accepts any voltage variant in the series. The breakdown voltage range (95 V min to 137 V clamp) places this part in the 85.5 V standoff class, typically used on 48 V to 72 V DC rails or automotive load-dump protection where the nominal bus sits below 85 V.
Active production — no PCN watch needed today
The base product number 1.5SMC100 covers the full family of unidirectional and bidirectional variants at this voltage class. The HM3/H suffix identifies the automotive-grade, AEC-Q101 qualified version with the TransZorb® silicon avalanche technology.
