HL2303 from hongjiacheng, 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 terminal; gate-source voltage is rated ±20 V (VGS), and gate threshold VGS(th) is -1 V min, -1.6 V typ, -3 V max at ID = -250 µA. |
| 2 | S | passive | Source terminal; continuous source-drain diode current IS is -0.83 A at TA = 25℃, with pulse diode forward current ISM of -10 A. |
| 3 | D | passive | Drain terminal; drain-source voltage VDS is -30 V, with continuous drain current ID of -1.9 A at TA = 25℃ (steady state). |
