BAS21-AU
PANJIT International · Switching Diodes · SOT-23
BAS21-AU 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; BAS21-AU is rated for 200 V reverse voltage (250 V peak) and 200 mA average rectified current. |
| 2 | NC | unconnected | No internal connection; the SOT-23 package diagram shows no connection to the diode on this pin. |
| 3 | K | passive | Cathode of the single switching diode; the package diagram shows the diode's cathode bar tied to this pin. |
