The part stands off the board on the lead bends; the axial format means it can be inserted into a PCB or wired point-to-point in a terminal block or busbar application. No special ESD handling beyond normal antistatic bench practice. Operating junction temperature range is -55°C to 175°C, so it handles hot environments like industrial enclosures or engine compartments without derating until the ambient pushes above 125°C or so. ## Sourcing reality — obsolete part Available through independent surplus and broker channels. Stock is lot-specific; we source and quote to order against your BOM line. Date codes and quantities confirmed at RFQ — no blanket availability claim.","metaTitle":"1.5KE68C-B Littelfuse TVS Diode, 1500W, DO-201","metaDescription":"Obsolete 1.5KE68C-B TVS diode from Littelfuse, 1500W peak pulse, 58.1V standoff, DO-201 axial.
