5.0SMDJ40A

DOWO · TVS · SMC(DO-214AB)

5.0SMDJ40A from DOWO, in a SMC(DO-214AB). 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, marked by the color band on the package; connects to the protected line, with VRWM 40.0 V, VBR 44.40 to 49.10 V at 1 mA, and VC 64.5 V at IPP 77.5 A for the 5.0SMDJ40A.
2 A passive Anode, the end opposite the color band, normally connected to ground for the unidirectional 5.0SMDJ40A, which is rated 5000 W peak pulse power (10/1000 µs).
