# KDS184-RTK

**KEC Semicon** · Switching Diodes · SOT-23

KDS184-RTK from KEC Semicon, 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 | ANODE 1 | passive | Anode of the first diode element; the device is rated for a reverse voltage VR of 80 V and a maximum peak reverse voltage VRM of 85 V. |
| 2 | ANODE 2 | passive | Anode of the second diode element; the device is rated for a reverse voltage VR of 80 V and a maximum peak reverse voltage VRM of 85 V. |
| 3 | CATHODE | passive | Common cathode shared by both diode elements, per the pin list (the printed text reads 'CATHODE 2 1'); total power dissipation PD is 150 mW. |

## CAD (KiCad official)

- Symbol: `KDS184-RTK`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `kds184-rtk-etched.step` / `kds184-rtk-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `kds184-rtk.step` / `kds184-rtk.glb` are the bare package body.
