KI2333CDS from KEXIN, 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 | Gate | input | Gate terminal of the P-channel MOSFET; gate-source voltage is rated at ±8 V (VGS). |
| 2 | Source | passive | Source terminal of the P-channel MOSFET; the datasheet gives no separate pin limit, and the device is rated for a drain-source voltage of -12 V (VDS). |
| 3 | Drain | passive | Drain terminal of the P-channel MOSFET; rated for -12 V drain-source voltage and -5.1 A continuous drain current at Ta = 25℃ (steady state). |
