I have a blown diode in the circuitry of my Dewalt DE116-xe charger. The number on the diode is P6KE51A with 727 under it. I was wondering where I might be able to purchase one of these diodes or perhaps get a circuit diagram from. Frank

I bought 20 of those from Allied electronics using your original part #. I can tell that I have worked 5 of those chargers and that is not the only part blown. Usually 2 diodes on the left, 2 of the 3904 transistors, the 2 amp fuse, the 2 resistors (2.4 ohm and .1 ohm ) in front of the mosfet which is probably bad also. I now have one with a bad 18 pin dip ic that I can't find the ic anywhere (it is surely propriatary). I have looked for a schematic for a long time and thats how I found this thread. Good luck.
