TECH PUBLIC · MOSFETs · SOT-23-3
SI2318CDS from TECH PUBLIC, in a SOT-23-3. 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; gate-source voltage limit is ±20 V, with gate threshold of 1 V min to 3 V max at ID = 250 µA. |
| 2 | S | passive | Source; continuous drain current is 3.9 A and the body diode forward voltage is 0.8 V typ, 1.2 V max at IS = 1.25 A. |
| 3 | D | passive | Drain; drain-source voltage is rated 40 V, with pulsed drain current of 16 A and RDS(on) of 45 mΩ max at VGS = 10 V. |
