The breakdown voltage range starts at 90 V, so the device begins conducting just above the normal operating rail. The DO-201AA axial package (also known as DO-27) is a through-hole form factor suited for point-to-point wiring or PCB mounting where a robust mechanical connection is needed. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1.5KE100-B as obsolete. No official successor is listed, so new designs should consider an alternative TVS with similar standoff and clamping specs in the same DO-201 footprint. For existing BOM lines, this part is available through independent surplus and broker channels.","metaTitle":"Littelfuse 1.5KE100-B TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE100-B Zener TVS diode, 1500W peak pulse, 85.5V standoff, DO-201 axial.
