NTR2101PT1G

onsemi · MOSFETs · SOT-23

NTR2101PT1G from onsemi, 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 Gate terminal of the P-channel MOSFET; the datasheet limits gate-to-source voltage VGS to ±8.0 V.
2 Source passive Source terminal of the P-channel MOSFET; the body diode source current IS is limited to −1.2 A.
3 Drain passive Drain terminal of the P-channel MOSFET; the datasheet rates drain-to-source voltage VDSS at −8.0 V and continuous drain current ID at −3.7 A (t ≤ 5 s, TA = 25°C).
