The SI2302DS from Vishay is a 20V N-channel enhancement-mode Trench MOSFET in a SOT-23 package. With RDS(on) of 65mOhm at VGS=4.5V and 2.2A continuous drain current, it provides a good balance of on-resistance and current capability in the industry’s smallest power MOSFET footprint. The low gate threshold (0.65-1.2V) enables direct drive from 2.5V or 3.3V logic, and the 6nC gate charge supports fast switching. The trench MOSFET technology achieves lower RDS(on) than planar devices of the same die size. The SI2302DS is widely used in load switches, DC-DC converters, and motor drivers in portable electronics, IoT devices, and battery-powered systems.

The SI2302DS uses trench MOSFET technology where vertical trenches are etched into the silicon and lined with gate oxide and polysilicon gate material. When VGS exceeds the threshold (0.65-1.2V), inversion layers form on the trench sidewalls, creating multiple parallel conduction channels between source and drain. This 3D structure packs more channel width per unit die area than planar MOSFETs, achieving 65mOhm RDS(on) in a small SOT-23 die. The 6nC gate charge results from the compact die size, allowing the gate to be driven from low-power MCU GPIO pins without dedicated gate drivers. The body diode provides a natural freewheeling path for inductive loads.
