BAS21H from LGE, in a SOD-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 | CATHODE | passive | Cathode of the switching diode; withstands VR 250 V continuous and VRRM 250 V, with forward continuous current IF 200 mA. |
| 2 | ANODE | passive | Anode of the switching diode; forward voltage max 1000 mV at IF=100 mA and 1250 mV at IF=200 mA, peak forward surge current 625 mA. |
