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.","metaTitle":"1.5KE12C Littelfuse TVS Diode, 1500W, 10.2V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE12C bidirectional TVS diode, 1500W peak pulse, 10.2V standoff, DO-201 axial.
