**Yangzhou Yangjie Elec Tech** · Diodes - General Purpose · SMC(DO-214AB)

GS8MQ from Yangzhou Yangjie Elec Tech, in a SMC(DO-214AB). 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, the end marked by the color band; the device is rated for VRRM of 1000 V (GS8MQ) and 8.0 A average rectified output current. |
| 2 | A | passive | Anode terminal of the rectifier diode; forward voltage drop is 1.1 V max at IFM=8.0 A. |
