SMCJ22AX
Shenzhen JingYang · TVS · SMC
SMCJ22AX from Shenzhen JingYang, in a SMC. 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 cathode band on the unidirectional SMCJ22A (VRWM 22V, VBR 24.4-28.0V at 1mA, VC 35.5V at 42.3A IPP). |
| 2 | A | passive | Anode, the terminal opposite the cathode band on the unidirectional SMCJ22A, which carries 1500W peak pulse power on 10/1000us. |
