CMS3415-HF from Comchip, 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; gate-source voltage limit is ±10V, with operation at gate voltages as low as 1.8V and ESD rating of 2500V HBM. |
| 2 | S | passive | Source; continuous drain current is -4A (pulsed -30A) for this P-channel MOSFET. |
| 3 | D | passive | Drain; drain-source voltage is rated -20V with RDS(ON) below 45mΩ at VGS = -4.5V. |
