Product details

AEC-Q101 qualified — the OEM auditor will ask for PPAP

The 1.5SMC220CAHM3_A/H carries AEC-Q101 qualification as part of the Automotive, 1.5SMC, TransZorb® series — this means it has passed the reliability stress tests (HTRB, H3TRB, TC, and ESD) required for PPAP submission to IATF 16949 customers. The operating temperature range of -65°C to 150°C (TJ) covers the full underhood and engine-bay profile, from cold-crank to hot-soak.

Package and board-fit — DO-214AB (SMC) footprint

Single bidirectional channel: one device protects both polarities on a signal or power rail, saving placement cost versus two unidirectional parts in series.

Sourcing and compliance — active, quoted to order

Product status is Active, meaning the original manufacturer continues to produce this order code. Base product number 1.5SMC220 — the suffix CAHM3_A/H denotes the automotive AEC-Q101 grade and the bidirectional polarity. Compliance documentation (RoHS, REACH, UL) is available from the Vishay General Semiconductor - Diodes Division datasheet.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5SMC220CAHM3_A/H in this Circuit Protection family?

Within the same 1.5SMC series, the non-automotive variant (e.g., 1.5SMC220CA) shares the same DO-214AB package and electrical ratings (185V standoff, 328V clamp, 1500W peak pulse) but lacks AEC-Q101 qualification.

What compliance documentation does Vishay General Semiconductor - Diodes Division provide for 1.5SMC220CAHM3_A/H (RoHS, REACH, UL, IEC)?

As an AEC-Q101 qualified part, Vishay provides PPAP documentation, RoHS compliance certificates, and REACH declarations via the product datasheet. UL recognition for the 1.5SMC series is standard; specific file numbers are listed in the Vishay application note for TVS diodes.
