# KSI2305CDS-T1-GE3

**KUU** · MOSFETs · SOT-23

KSI2305CDS-T1-GE3 from KUU, 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 limited to ±12 V with threshold of -0.5 to -1 V. |
| 2 | SOURCE | passive | Source terminal; continuous source-drain diode current is -0.72 A (max rating) and drain-source voltage is limited to -20 V. |
| 3 | DRAIN | passive | Drain terminal; rated for -20 V drain-source voltage and -4 A continuous drain current (-20 A pulsed), RDS(on) max 65 mΩ at -4.5 V. |
