# B340AE

**FUXINSEMI** · Schottky Diodes · SMA(DO-214AC)

B340AE from FUXINSEMI, in a SMA(DO-214AC). 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 | CATHODE | passive | Cathode terminal, identified by the color band on the package body (polarity: color band denotes cathode end); the datasheet gives no separate electrical limits for this pin alone. |
| 2 | ANODE | passive | Anode terminal; the datasheet's maximum ratings (for example 40 V repetitive peak reverse voltage and 3.0 A average forward rectified current at TL) apply across anode to cathode, with no separate pin-level limit given. |

## CAD (KiCad official)

- Symbol: `B340AE`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
- 3D model files: `b340ae-etched.step` / `b340ae-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `b340ae.step` / `b340ae.glb` are the bare package body.
