The DO-201 body is common for 1.5kW TVS diodes and mates with standard 0.040-inch diameter lead holes on a PCB. The axial leads allow either vertical or horizontal mounting depending on board layout constraints. Supplied in Tape & Reel packaging, the part is compatible with automated insertion equipment for volume assembly. ## Sourcing reality for an obsolete part Buyers should verify the exact date code and lot traceability requirements with their sourcing desk.","metaTitle":"Littelfuse 1.5KE120C TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE120C bidirectional Zener TVS diode, 1500W peak pulse, 102V standoff, 173.25V clamp.
