Pinout

Pin Name Type Function
1 K passive Cathode, the end marked by the color band on the unidirectional 1.5KE39A; connects to the positive side of the line being protected, with VRWM 33.30 V and VBR 37.10~41.00 V at 1 mA.
2 A passive Anode, the axial lead opposite the cathode band, normally tied to ground or the return side; clamps at VC 53.9 V at IPP 28.2 A (10/1000μs).
