P4KE150A

Brightking · ESD And Surge Protection (TVS/ESD) · DO-41

P4KE150A from Brightking, in a DO-41. 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 Cathode passive Cathode lead, identified by the color band on the body (the datasheet states the color band denotes cathode for all types except bi-directional models); for the P4KE150A it has a reverse stand-off voltage VRWM of 128 V and a maximum clamping voltage VC of 207 V at IPP 2.0 A.
2 A passive Anode lead, the axial end opposite the cathode band; the datasheet gives a breakdown voltage VBR of 143-158 V at a test current IT of 1 mA and a reverse leakage IR of 1 µA maximum at VRWM for this lead pair, with no separate pin function stated.
