HXY MOSFET · MOSFETs · SOT-23
SM3400SRL-HXY from HXY MOSFET, 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 terminal; the gate-source voltage is rated ±12 V (VGS), and the device is specified for operation with gate voltages as low as 2.5 V. |
| 2 | D | passive | Drain terminal; the device is rated for a drain-source voltage of 30 V and a continuous drain current of 5.8 A. |
| 3 | S | passive | Source terminal; the datasheet gives no pin-specific limit, and the device-level ratings are VDS 30 V, VGS ±12 V and a junction and storage temperature range of -55 to 150 ℃. |
