UG2D from Yangzhou Yangjie Elec Tech, in a SMB(DO-214AA). 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 cathode line on the DO-214AA (SMB) package; rated VRRM 200 V for UG2D. |
| 2 | A | passive | Anode terminal, the end opposite the cathode line on the DO-214AA (SMB) package; average rectified current 2.0 A for UG2D. |
