Changjing · Schottky Diodes · SOT-23
BAR43C from Changjing, 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 in the BAR43C common-cathode pair (marking DB2), with 30 V peak repetitive reverse voltage and 200 mA average forward current. |
| 2 | A2 | passive | Anode of the second Schottky diode in the BAR43C common-cathode pair, with 30 V peak repetitive reverse voltage and 200 mA average forward current. |
| 3 | K | passive | Common cathode of both Schottky diodes, tied together internally, with 30 V reverse voltage rating and a maximum reverse current of 0.5 µA at VR=25 V. |
