TF3400B

TF · MOSFETs · SOT-23

TF3400B from TF, 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 GATE input MOSFET gate terminal; the datasheet's absolute maximum gate-source voltage is ±12 V.
2 SOURCE passive MOSFET source terminal; the datasheet gives no pin-specific limit for this terminal beyond the device ratings.
3 DRAIN passive MOSFET drain terminal; the datasheet's drain-source voltage rating is 30 V and continuous drain current is 5.0 A at TA=25°C.
