**Shandong Jingdao Microelectronics** · Diodes - General Purpose · SMC(DO-214AB)

S5KC from Shandong Jingdao Microelectronics, 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 | Cathode | passive | Cathode terminal of the S5KC rectifier, which the family rating table lists at 800 V maximum repetitive peak reverse voltage (VRRM) with 5 A maximum average forward rectified current (IF(AV)). |
| 2 | Anode | passive | Anode terminal of the S5KC rectifier, which carries the forward current (5 A average, 120 A peak surge for 8.3 ms) rated in the datasheet. |
