The leads are long enough for hand-soldering or wave solder, and the body is clearly marked with the part number and polarity band — orientation is obvious, so you can swap it in the field without a microscope. ## Sourcing and compliance Littelfuse marks the 1.5KE180 as obsolete. We source this part through independent distribution; lot traceability and RoHS/REACH compliance documentation are available at RFQ.","metaTitle":"1.5KE180 Littelfuse TVS Diode, 1500W, DO-201","metaDescription":"1.5KE180 Littelfuse Zener TVS diode, 1500W peak pulse, 154V standoff, 258.3V clamp.
