# BAV99-TP

**MCC Micro Commercial Components** · Switching Diodes · SOT-23

BAV99-TP from MCC Micro Commercial Components, 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 | A | passive | Anode of the first diode (bottom-left lead in the package drawing); the series pair is rated 70V DC blocking voltage, 200mA average rectified current. |
| 2 | C | passive | Cathode of the second diode (bottom-right lead in the package drawing); reverse breakdown voltage 100V min at IR=100uA. |
| 3 | C/A | passive | Common node joining the cathode of the first diode to the anode of the second diode (single top lead in the package drawing). |

## CAD (KiCad official)

- Symbol: `BAV99-TP`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bav99-tp-etched.step` / `bav99-tp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bav99-tp.step` / `bav99-tp.glb` are the bare package body.
