This is a single bidirectional device, meaning one P6KE39CA-B replaces two unidirectional diodes back-to-back on a bipolar signal pair, saving board space and insertion loss. The 37.1V minimum breakdown voltage ensures the device does not conduct during normal operation on a 33.3V rail, while the 53.9V clamp catches overvoltage events before they reach the load. ## Through-hole DO-15 package and temperature range Housed in the DO-204AC (DO-15) axial leaded package, the P6KE39CA-B is a through-hole part suited for point-to-point wiring, terminal block integration, or PCB mounting where wave soldering or hand soldering is preferred. The axial leads allow vertical or horizontal placement depending on board clearance requirements. The wide temperature span means the clamping performance holds across cold-start and hot-soak conditions in outdoor or engine-bay enclosures.","metaTitle":"P6KE39CA-B Diodes Inc TVS Diode, 600W, 33.3V Standoff","metaDescription":"Active P6KE39CA-B bidirectional TVS diode from Diodes Inc, 600W peak pulse power, 33.3V reverse standoff, 53.9V clamp at 11.2A.
