For a 48V bus or a 60V DC rail, the 58.1V standoff keeps the diode out of conduction during normal operation, while the 96.6V clamp protects downstream silicon rated for 100V or higher. ## Package and rework reality — DO-201 axial The DO-201AA (DO-27) axial through-hole package is a rework-friendly form factor — the leads are thick enough to survive a couple of heat cycles from a soldering iron or hot-air station without lifting the pad. Pin 1 is the cathode band on the body; the bidirectional construction means the banded end is not polarity-sensitive for the clamping direction, but the orientation still matters for PCB silkscreen consistency. The 175°C TJ limit is the die-attach solder reflow ceiling — keep the board-level soldering profile below that peak.","metaTitle":"1.5KE68C Littelfuse TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE68C bidirectional TVS diode, 1500W peak pulse power, 58.1V standoff, DO-201 axial.
