# DS34W

**TECH PUBLIC** · Schottky Diodes · SOD-123

DS34W from TECH PUBLIC, in a SOD-123. 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 or cathode notch; DS34W has VRRM/VRWM/VR of 40 V and VR(RMS) of 28 V. |
| 2 | A | passive | Anode; DS34W carries 3.0 A average rectified output current (TL = 75°C) with VFM of 0.55 V at IF = 3.0 A. |

## CAD (KiCad official)

- Symbol: `DS34W`
- Footprint: `Diode_SMD:D_SOD-123F`
- 3D model: SOD-123 (KiCad packages3D, STEP)
- 3D model files: `ds34w-etched.step` / `ds34w-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ds34w.step` / `ds34w.glb` are the bare package body.
