SM520 from Jiangsu JieJie Microelectronics, in a DO-214AC(SMA). 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 terminal, the end marked by the color band; the part blocks up to VRRM 2000 V and conducts up to 1.5 A average forward current at TL=100℃. |
| 2 | A | passive | Anode terminal, the end opposite the color band; forward voltage is 1.15 V max at IF=1.5 A. |
