Product details

Clamping a 12.8 V rail with 1.5 kW headroom

The 1.5SMC15A: It clamps a 10/1000 µs surge to 21.2 V maximum while absorbing 1500 W of peak pulse power — enough headroom to handle a load-dump or inductive kick without the part failing short.

Breakdown and clamping window

The reverse standoff voltage is 12.8 V, meaning the diode stays high-impedance below that level and does not load the protected rail. The DO-214AB (SMC) package is surface-mount, with a low-inductance footprint that preserves the fast response time inherent to Zener avalanche breakdown.

Active production, single-source BOM line

For a BOM line that cannot tolerate a single-supplier exposure, qualifying an alternate TVS from a different family with the same 12.8 V standoff and DO-214AB footprint is a prudent hedge.
