NM2302B

Shandong Jingdao Microelectronics · MOSFETs · SOT-23

NM2302B from Shandong Jingdao Microelectronics, 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 N-channel MOSFET; the gate-source voltage is rated ±12 V (VGSS).
2 Drain passive Drain terminal of the N-channel MOSFET; rated 20 V drain-source voltage (VDSS) and 3 A continuous drain current (ID).
3 Source passive Source terminal of the N-channel MOSFET, the reference for the gate-source rating (±12 V) and the drain-source rating (20 V VDSS).
