Product details

Automotive-grade TVS for 28V rails

The 1.5SMC33CAHM3_A/H: The bidirectional structure means a single device clamps both positive and negative transients, saving board space versus back-to-back unidirectional parts.

Package and reflow readiness

The AEC-Q101 qualification includes moisture sensitivity level (MSL) testing per JEDEC — verify the specific MSL rating on the lot certificate before reflow to avoid popcorning, especially if the part has been stored outside the dry-pack seal.

As an AEC-Q101 qualified device, it ships with full traceability and lot-level test data. Compliance documentation (RoHS, REACH, conflict minerals reporting) is maintained by Vishay and provided with each shipment.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5SMC33CAHM3_A/H?

Any functionally equivalent TVS must match the 28.2 V standoff, bidirectional configuration, 1.5 kW peak pulse rating, and DO-214AB package. Confirm the clamping voltage and breakdown tolerance before substituting.
