Single FETs, MOSFETs Procurement Notes

Verify the manufacturer source carefully, as Fairchild Semiconductor's semiconductor division was acquired by onsemi. Ensure the component label matches the original Fairchild branding if specific legacy sourcing is required. Confirm the package type and date code align with project specifications. Request datasheets to validate electrical parameters against current design requirements before finalizing procurement decisions.

Single FETs, MOSFETs Selection Notes

Select this component when a 60V N-channel MOSFET with low RDS(on) is needed for logic-level driven applications. It is suitable for designs where gate drive voltage may be limited to 5V or 10V. Consider the DPAK package for its balance of current handling and PCB space efficiency. Evaluate thermal management needs based on the 20A continuous current rating and expected duty cycles in the target application.

Single FETs, MOSFETs Part Context

The HUF76423D3S belongs to the UltraFET series, representing Fairchild's trench MOSFET technology. This series focuses on reducing conduction and switching losses in power supplies. The part is part of a broader family of 60V devices, offering various current ratings and resistance values to suit different power density requirements in consumer and industrial electronics.

Single FETs, MOSFETs Replacement Considerations
