Product details

68V standoff TVS — what the clamping spec means for the protected rail

The 1.5SMC68CAHM3/H: At 1500 W peak pulse power the 1.5SMC68 handles the 1.5 kW transient without degradation in the unclamped window; this is the figure that governs part selection when the board's surge exposure exceeds what a smaller TVS can absorb.

AEC-Q101 qualification and the automotive-plus-telecom target

Vishay lists both Automotive and Telecom as the application segments, which means the same part number serves on-board DC power protection in an ECU and on the telecom rail feeding remote radio units — the AEC-Q101 screening does not restrict it to in-vehicle use only.

Quoted to order through independent distribution against BOM quantities; availability and lead time confirmed at RFQ.
