# BAT54E6327HTSA1

**Infineon Technologies** · Schottky Barrier Diodes (SBD) · SOT-23

BAT54E6327HTSA1 from Infineon Technologies, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the single Schottky diode (BAT54, SOT23); diode is rated for VR 30 V and IF 200 mA. |
| 2 | NC | unconnected | Not connected internally; the BAT54 single-diode symbol shows only pins 1 and 3 connected to the diode. |
| 3 | K | passive | Cathode of the single Schottky diode (BAT54, SOT23); diode is rated for VR 30 V and IF 200 mA. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `BAT54E6327HTSA1`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.0 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
- 3D model files: `bat54e6327htsa1-etched.step` / `bat54e6327htsa1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bat54e6327htsa1.step` / `bat54e6327htsa1.glb` are the bare package body.
