# SI2303CDS-T1-E3

**Vishay Intertech** · MOSFETs · SOT-23

SI2303CDS-T1-E3 from Vishay Intertech, 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 of the P-channel MOSFET; gate-source voltage is limited to ±20 V (VGS). |
| 2 | S | passive | Source of the MOSFET; continuous source-drain diode current is limited to -1.75 A at TC = 25 °C (-0.83 A at TA = 25 °C). |
| 3 | D | passive | Drain of the MOSFET; drain-source voltage is -30 V (VDS) with continuous drain current of -2.7 A at TC = 25 °C. |
