# MBRA340T3G

**Tokmas** · Schottky Diodes · DO-214AC

MBRA340T3G from Tokmas, in a 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 | K | passive | Cathode, marked by the color band; the device blocks 40 V (VRRM/VRWM/VR) and passes 3.0 A average forward current (IO) at TL = 100°C. |
| 2 | A | passive | Anode; forward voltage is typically 0.450 V at IF = 3.0 A and TJ = 25°C. |

## CAD (KiCad official)

- Symbol: `MBRA340T3G`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: DO-214AC (KiCad packages3D, STEP)
- 3D model files: `mbra340t3g-etched.step` / `mbra340t3g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mbra340t3g.step` / `mbra340t3g.glb` are the bare package body.
