# PMBD914

**Nexperia** · Switching Diodes · SOT-23

PMBD914 from Nexperia, 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 terminal of the PMBD914 high-speed switching diode (Table 2, graphic symbol K/A). |
| 2 | n.c. | unconnected | Not connected; this pin has no internal connection in the PMBD914 SOT23 package. |
| 3 | K | passive | Cathode terminal of the diode; the soldering point of the cathode tab is the reference for the thermal resistance Rth(j-sp) of 330 K/W maximum. |

## CAD (KiCad official)

- Symbol: `PMBD914`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `pmbd914-etched.step` / `pmbd914-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pmbd914.step` / `pmbd914.glb` are the bare package body.
