BAP50-04W from YFW, in a SOT-323. 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 | Anode | passive | Anode terminal of one of the two planar PIN diodes in series; each diode is rated for 50 V continuous reverse voltage and 50 mA continuous forward current. |
| 2 | Cathode | passive | Cathode terminal of the other PIN diode in the series pair; each diode is rated for 50 V continuous reverse voltage and 50 mA continuous forward current. |
| 3 | Common connection | passive | Common connection node of the two series-configured diodes as labelled in the datasheet pinout; the datasheet gives no separate electrical limit for this pin. |
