HUF76639P3 is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists onsemi. Its product description is MOSFET N-CH 100V 51A TO220-3. Review the specifications below when checking this part for your BOM.
The HUF76639P3 is a single N-channel logic level UltraFET power MOSFET manufactured by Fairchild Semiconductor. It features a JEDEC TO-220AB package with a drain-to-source voltage rating of 100V and a continuous drain current capacity of 50A at 25°C case temperature. The device exhibits an ultra-low on-resistance of 0.027Ω at VGS=5V and 0.026Ω at VGS=10V. It supports a junction temperature range from -55°C to +175°C, includes unclamped inductive switching (UIS) capability, and provides temperature-compensated PSPICE and SABER simulation models for design verification.
Verify component authenticity through authorized distribution channels due to the product's obsolete status. Confirm that the specific ordering suffix matches the required package variant, as the datasheet indicates distinct packaging options exist within this family. Ensure all handling procedures comply with the manufacturer's quality system certifications referenced in the documentation.
Select this component when designing circuits requiring high current handling with low conduction losses under logic-level drive conditions. Evaluate the thermal resistance characteristics against the expected ambient operating environment. Consider the UIS rating limits if the application involves inductive load switching without external snubbing protection.
This part belongs to the UltraFET series of power MOSFETs designed for high-performance switching applications. It represents a legacy product line originally developed by Fairchild Semiconductor before corporate restructuring. The TO-220AB package facilitates through-hole mounting and effective heat dissipation via the drain flange connection.
