The 1.5SMC510AHM3_A/I: It is qualified to AEC-Q101, the automotive discrete semiconductor reliability standard, covering temperature cycling, ESD sensitivity, and PPAP readiness for tier-one ECU programs. Peak pulse current is 2.15 A under the same 10/1000 µs condition.
A 25 mm² pad on a 2 oz copper board keeps RθJA near 75 °C/W. The AEC-Q101 Grade 0 qualification means the part passes reliability stress at 150 °C ambient, not just storage — relevant for engine-bay or exhaust-adjacent mounting.
RoHS compliance is standard for the HM3 suffix; full REACH and conflict-minerals declarations are available from Vishay's compliance portal.
