TM2302DI

Tritech MOS · MOSFETs · SOT-23

TM2302DI from Tritech MOS, 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; controls the channel, with VGS rated ±12 V and a threshold of 0.4 V min to 1.0 V max at ID=250 µA.
2 S passive Source; the body diode runs from source to drain, with a continuous diode current of 3 A max.
3 D passive Drain; VDS is rated 20 V, continuous ID is 3.0 A at TA=25℃, and pulsed IDM is 9 A.
