No pin-compatible direct replacement is documented by the OEM. A functional substitute would require matching the 36.8V standoff, 600W peak pulse rating, and DO-15 axial package — a parametric search against those three constraints will yield candidates from multiple TVS diode families. ## Through-hole DO-15 — board integration and temperature range The DO-204AC (DO-15) axial-lead package is a through-hole form factor — it solders into a plated through-hole on the PCB, with the body standing off the board. This is a single-channel unidirectional device — the cathode band on the DO-15 body must be oriented toward the protected rail, anode to ground. No power line protection is specified, so it is intended for signal and low-power DC bus clamping, not AC mains or high-energy primary suppression.","metaTitle":"P6KE43A-T Diodes Inc Zener TVS, 600W, DO-15, Obsolete","metaDescription":"P6KE43A-T from Diodes Inc is an obsolete 600W unidirectional Zener TVS diode. 36.8V standoff, 40.9V breakdown, 59.3V clamp.
