UMW · MOSFETs · SOT-23
SI2300A from UMW, 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: MOSFET gate terminal; gate-source voltage is rated at ±12 V (VGS) in the absolute maximum ratings. |
| 2 | S | passive | SOURCE: MOSFET source terminal; continuous source-drain (body diode) current is rated at 0.6 A (IS). |
| 3 | D | passive | DRAIN: MOSFET drain terminal; drain-source voltage is rated at 20 V (VDS) and continuous drain current at 6 A (ID). |
