# DAN217

**Changjing** · Switching Diodes · SOT-23

DAN217 from Changjing, in a SOT-23. 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 | A1 | passive | Anode of the first diode element; the two diodes are connected in series, with the cathode of this diode joined to pin 3. |
| 2 | K2 | passive | Cathode of the second diode element; its anode is joined to pin 3, forming a series pair with pin 1's diode. |
| 3 | A2/K1 | passive | Common junction of the two series diodes (cathode of the diode from pin 1 and anode of the diode to pin 2); each diode is rated for 80 V reverse and 300 mA forward continuous current. |

## CAD (KiCad official)

- Symbol: `DAN217`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `dan217-etched.step` / `dan217-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dan217.step` / `dan217.glb` are the bare package body.
