SI2304DS

KEXIN · MOSFETs · SOT-23

SI2304DS from KEXIN, 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 enhancement MOSFET, with gate-source voltage rated at VGS ±20 V.
2 Source passive Source terminal of the N-channel enhancement MOSFET; the datasheet gives continuous drain current ID of 2.5 A at Ta=25℃ (surface mounted on FR4, t ≤ 5 sec).
3 Drain passive Drain terminal of the N-channel enhancement MOSFET, with drain-source voltage rated at VDS 30 V.
