BAT42W from hongjiacheng, in a SOD-123. 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 | K | passive | Cathode, the end marked by the cathode line on the package; the device blocks VR=30V (VRRM 30 V, VRMS 21 V) and passes IF(AV) 200 mA. |
| 2 | A | passive | Anode, the end opposite the cathode line; forward current up to IF(AV) 200 mA, with VF max 1.0 V at IF=200mA. |
