**SINO IC** · Switching Diodes · SOT-23

SEBAV99 from SINO IC, 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 | passive | Anode of the first diode of the dual series switching diode pair (VR 80 V DC, IFM 300 mA, Io 100 mA). |
| 2 | CATHODE | passive | Cathode of the second diode of the dual series switching diode pair (VR 80 V DC, IFM 300 mA, Io 100 mA). |
| 3 | CATHODE/ANODE | passive | Common series junction connecting the cathode of the first diode to the anode of the second diode. |

## CAD (KiCad official)

- Symbol: `SEBAV99`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `sebav99-etched.step` / `sebav99-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sebav99.step` / `sebav99.glb` are the bare package body.
