SMDJ9.0CA
Shandong Jingdao Microelectronics · TVS · SMC
SMDJ9.0CA from Shandong Jingdao Microelectronics, 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 | Cathode | passive | Cathode terminal per the PINNING table; the datasheet gives this pin for the Unipolar symbol and rates SMDJ9.0CA at a reverse stand-off voltage VRWM of 9.0 V. |
| 2 | Anode | passive | Anode terminal per the PINNING table; for SMDJ9.0CA the datasheet lists a minimum breakdown of 10 V and a maximum of 11.1 V at a test current of 1 mA. |
