Changjing · Schottky Diodes · SOD-123
B0520LW 环保 from Changjing, 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 (marked "-" in the package drawing, on the banded end); the datasheet gives VR/VRRM of 20 V for B0520LW and an average rectified output current of 0.5 A. |
| 2 | A | passive | Anode (marked "+" in the package drawing); the datasheet gives a forward voltage of 0.385 V typ. limit at IF=0.5A for B0520LW. |
