**Infineon Technologies** · Schottky Diodes · SOT-323

BAS4005WH6327XTSA1 from Infineon Technologies, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of diode D1. Forms a Schottky junction with the shared cathode (pin 3). VR max 40 V, IF max 120 mA, typical VF ~310 mV at 1 mA and ~450 mV at 10 mA. |
| 2 | A2 | passive | Anode of diode D2. Forms a Schottky junction with the shared cathode (pin 3). VR max 40 V, IF max 120 mA, typical VF ~310 mV at 1 mA and ~450 mV at 10 mA. |
| 3 | K | passive | Common cathode shared by both diodes D1 and D2 (common-cathode configuration). |
