GS3MBQ 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, marked by the cathode line on the package body; GS3MBQ is rated at VRRM 1000 V, 3.0 A average rectified output current. |
| 2 | A | passive | Anode terminal at the end opposite the cathode line; GS3MBQ has a maximum forward voltage of 1.15 V at IFM=3.0 A. |
