**Yangzhou Yangjie Elec Tech** · Switching Diodes · SOT-23

BAV23CQ from Yangzhou Yangjie Elec Tech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of diode 1. Forward continuous current IF ≤ 225 mA per leg, VF ≤ 1 V @ 100 mA. Non-repetitive peak surge IFSM = 1.7 A (tp = 10 ms). |
| 2 | A2 | passive | Anode of diode 2. Forward continuous current IF ≤ 225 mA per leg, VF ≤ 1 V @ 100 mA. Non-repetitive peak surge IFSM = 1.7 A (tp = 10 ms). |
| 3 | K | passive | Common cathode shared by both diodes. Reverse voltage VRRM = 250 V; reverse current IR ≤ 0.1 µA @ VR = 200 V; total capacitance Ctot ≤ 5 pF @ 1 MHz, VR = 0 V. |

## CAD (KiCad official)

- Symbol: `BAV23CQ`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bav23cq-etched.step` / `bav23cq-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bav23cq.step` / `bav23cq.glb` are the bare package body.
