PANJIT International · Switching Diodes · SOT-23
BAS21_R1_00001 from PANJIT International, 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 | A | passive | Anode of the single switching diode (top view, lower-left pin); BAS21 is rated for 200 V reverse voltage VR and 200 mA average rectified current IO. |
| 2 | NC | unconnected | No internal connection shown in the single-diode SOT-23 pin drawing. |
| 3 | K | passive | Cathode of the single switching diode (top pin); BAS21 peak reverse voltage VRM is 250 V. |
