# DSK120-K120

**JUXING** · Schottky Diodes · SOD-123FL

DSK120-K120 from JUXING, in a SOD-123FL. 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 Schottky rectifier; for the DSK120 the datasheet rates the repetitive peak reverse voltage at 200 V and the average forward rectified current at 1.0 A. |
| 2 | Anode | passive | Anode terminal of the Schottky rectifier, which conducts forward current up to 1.0 A average with a peak forward surge current of 30 A (8.3 ms half sine). |
