The junction operates from -55 °C to 175 °C, covering the full industrial and automotive under-hood temperature envelope. The axial body conducts heat through the leads into the PCB copper — keep the lead length short and the pad area generous to keep the junction below 175 °C under repetitive surge conditions. The through-hole form factor suits point-to-point wiring on terminal strips as well as PCB mounting — a common choice in power supplies, motor drives, and telecom line cards where a single TVS clamps the input bus. ## Active production — sourced per RFQ Littelfuse lists the 1.5KE11CA as Active in its current product portfolio. For volume builds, the tape-and-reel packaging option supports automated insertion. Cut-tape quantities are also available for prototyping or low-volume production. The base part number 1.5KE covers a wide voltage range — if the 9.4 V standoff is not the exact rail voltage, a sibling in the same package and power class exists without a board change.","metaTitle":"1.5KE11CA Littelfuse TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"1.5KE11CA Littelfuse bidirectional TVS diode, 1500W peak pulse power, 9.4V standoff, 15.6V clamp.
