Product details

Obsolete — sourcing through independent channels

The 1.5KE12C: Available through independent surplus and broker channels; each lot is date-code verified and quoted per RFQ. No stock-holding claim — availability confirmed at quote time.

1500 W peak pulse — clamping and breakdown voltages

Breakdown voltage starts at 10.8 V (minimum) and the reverse standoff is 10.2 V — the TVS stays transparent below 10.2 V and begins conducting at the breakdown knee, protecting a 10 V rail from transients that would otherwise push the line above the clamp ceiling.

DO-201 axial — through-hole mounting

Housed in the DO-201AA / DO-27 axial-lead package (also called DO-201) — a through-hole footprint that suits point-to-point wiring or PCB mounting where the lead bend radius and hole diameter match the standard 0.040-inch lead.
