# SBAV99WT1G

**onsemi** · Switching Diodes · SOT-323

SBAV99WT1G from onsemi, in a SOT-323. 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 terminal of the dual series switching diode, with each diode rated for 100 V reverse voltage and 215 mA forward current per the Maximum Ratings table. |
| 2 | CATHODE | passive | Cathode terminal of the dual series switching diode, with each diode rated for 100 V reverse voltage and 215 mA forward current per the Maximum Ratings table. |
| 3 | CATHODE-ANODE | passive | Common cathode/anode node of the two series diodes, which the datasheet labels as the CATHODE-ANODE connection in the STYLE 9 pinout. |

## CAD (KiCad official)

- Symbol: `SBAV99WT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `sbav99wt1g-etched.step` / `sbav99wt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sbav99wt1g.step` / `sbav99wt1g.glb` are the bare package body.
