FFPF06U40DPTU

Diode Arrays Overview

The FFPF06U40DPTU is a silicon ultra-fast recovery rectifier diode manufactured by Fairchild Semiconductor. It features a single-phase, one-element configuration housed in a TO-252 (DPAK) surface-mount package with two terminals. The device is rated for a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 6A. Key electrical characteristics include a fast recovery time and low forward voltage drop, designed for high-efficiency power conversion applications.

Diode Arrays Feature Summary

• Ultra-fast recovery characteristics minimize switching losses during operation
• Low forward voltage drop improves overall system efficiency
• Surface-mount DPAK package facilitates automated PCB assembly

Diode Arrays Applications

• High-frequency DC-to-DC converter circuits
• Free-wheeling rectification in synchronous buck converters
• Isolated output rectification in flyback power supplies

Diode Arrays Procurement Notes

Verify the specific suffix 'DPTU' against official Fairchild or ON Semiconductor datasheets to confirm the exact tape-and-reel packaging quantity and lead frame material. Ensure the component matches the required thermal resistance specifications for the intended PCB copper area. Cross-reference the manufacturer's current product status to confirm availability and lifecycle stage before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component when a surface-mount solution is required for medium-current applications up to 6A. The 400V rating suits general-purpose AC/DC adapters and industrial power supplies. Compare thermal performance metrics against alternative packages like TO-220 if heat dissipation constraints are critical. Verify that the ultra-fast recovery speed aligns with the switching frequency of the target circuit design.

Diode Arrays Part Context

This part belongs to the FFPF series of ultra-fast recovery rectifiers from Fairchild Semiconductor, now part of ON Semiconductor. The series offers various voltage and current ratings packaged in through-hole and surface-mount formats. The DPTU designation indicates a specific surface-mount variant optimized for high-volume manufacturing processes.

Diode Arrays Replacement Considerations

Check for direct equivalents within the ON Semiconductor portfolio, such as other FFPF series parts with matching current and voltage ratings. Verify pinout compatibility and thermal characteristics when substituting with components from other manufacturers.
