Protection window and key ratings
The 1.5KE68C-B: This 35.4V window between standoff and clamp tells you the voltage excursion the protected circuit must survive before the diode absorbs the transient.
Package and board integration
Through-hole DO-201AA (DO-27) axial package — the leads are 0.96 mm diameter typical, and the body is about 7.6 mm long. 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.
