P6KE51A-T

Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · DO-15

P6KE51A-T from Diodes Incorporated, in a DO-15. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode lead, marked by the cathode band on the unidirectional P6KE51A; it connects to the protected positive line and the device clamps at 70.1V max at 8.6A IPP (VRWM 43.6V).
2 A passive Anode lead, at the end opposite the cathode band; it connects to the return or ground side and the device is rated for 600W peak pulse power (tP = 1.0ms).
