# BAT64-04

**YFW** · Schottky Diodes · SOT-23

BAT64-04 from YFW, 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 | A1 | passive | Anode of the first Schottky diode (BAT64-04 series pair), 40 V max reverse voltage, 0.25 A forward current. |
| 2 | K2 | passive | Cathode of the second Schottky diode (BAT64-04 series pair), 40 V max reverse voltage, 0.25 A forward current. |
| 3 | K1/A2 | passive | Common midpoint connecting the cathode of the first diode to the anode of the second diode in the BAT64-04 series configuration. |

## CAD (KiCad official)

- Symbol: `BAT64-04`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bat64-04-etched.step` / `bat64-04-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bat64-04.step` / `bat64-04.glb` are the bare package body.
