HX3403 from HX hengjiaxing, in a SOT-23. 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; drive with VGS limited to ±12 V, threshold VGS(th) -0.5 V min to -1.5 V max, usable at gate voltages as low as 2.5 V. |
| 2 | S | passive | Source of the P-channel MOSFET; the body diode forward current is limited to -1.25 A. |
| 3 | D | passive | Drain; VDS maximum -30 V, continuous drain current -2.6 A and pulsed drain current -12 A. |
