RFD20N03SM9AR4770

Overview

The RFD20N03SM9AR4770 is an N-channel MOSFET array manufactured by Fairchild Semiconductor. It features a drain-source voltage (Vdss) of 30 V and a continuous drain current (Id) of 20 A. The device exhibits a maximum on-resistance (Rds(on)) of 0.025 ohms at specified gate-source voltages. This component is designed for surface-mount applications, providing efficient power switching capabilities within its electrical ratings.

Feature Summary

Dual N-channel configuration integrated into a single package
Low on-resistance for improved conduction efficiency
Surface-mount technology for compact circuit board integration

Applications

DC-DC converter circuits
Power management modules
Motor control systems

Procurement Notes

Verify the specific suffix AR4770 against official Fairchild documentation to confirm exact binning or tape-and-reel specifications. Ensure compatibility with standard surface-mount reflow profiles. Cross-reference datasheet parameters for thermal resistance and gate charge requirements prior to final design implementation.

Selection Notes

Select this component when a dual N-channel MOSFET solution is required with a 30 V rating and 20 A current capacity. The low Rds(on) value supports high-efficiency designs. Evaluate thermal performance and package constraints to ensure adequate heat dissipation in the target application environment.

Part Context

Fairchild Semiconductor specializes in power discrete components. This part belongs to their MOSFET array lineup, offering integrated switching solutions. The manufacturer provides technical documentation detailing absolute maximum ratings and electrical characteristics for system designers.

Replacement Considerations

Consult official Fairchild replacement guides for direct equivalents. Verify pinout compatibility and electrical parameter alignment before substituting.
