G1003B-23 from GOFORD, in a SOT-23-3L. 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 | G | input | Gate; gate-source voltage limited to ±25 V absolute maximum, threshold 1 to 3 V at 250 µA, and drives fully at gate voltages as low as 4.5 V. |
| 2 | S | passive | Source; continuous drain current 5 A at Tc=25℃, body diode source-drain current 12 A. |
| 3 | D | passive | Drain; drain-source voltage rated 100 V, continuous drain current 5 A at Tc=25℃ and 12 A pulsed. |
