# RC3400A

**RealChip** · MOSFETs · SOT-23

RC3400A from RealChip, 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 limited to ±12 V absolute maximum, with VGS(th) of 0.6 V min to 1.5 V max at ID=250µA. |
| 2 | S | passive | Source of the N-channel MOSFET; the body diode runs from source to drain with VSD max 1.2 V at IS=1.25A. |
| 3 | D | passive | Drain; drain-source voltage rated 30 V maximum and continuous drain current 5.8 A. |
