BL2302

GME(银河微电) · IC · SOT-23

BL2302 from GME(银河微电), 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 ±8 V (VGSS), threshold 0.6 to 1.2 V at 250 µA, and electrostatic sensitive.
2	D	passive	Drain; drain-source voltage 20 V (VDSS), continuous drain current 2.8 A at TA=25℃ and pulsed 10 A.
3	S	passive	Source; RDS(ON) is at most 45 mΩ at VGS=4.5 V and 59 mΩ at VGS=2.5 V.
