Diode Arrays Procurement Notes

Verify the specific manufacturer origin, as the datasheet indicates Fairchild Semiconductor International. Confirm RoHS compliance status and check for obsolescence or lifecycle changes, as the document references a September 2000 revision. Ensure the TO-3P through-hole package matches your board design requirements before finalizing procurement.

Diode Arrays Selection Notes

Select this component for high-frequency applications requiring fast switching speeds and low reverse recovery charge. The TO-3P package provides robust thermal management capabilities suitable for high-current scenarios. Consider the 400 V rating and 10 A continuous current limits when designing the circuit to ensure operation within absolute maximum ratings.

Diode Arrays Part Context

This part belongs to the FFA series of ultrafast recovery power rectifiers originally manufactured by Fairchild Semiconductor. The 'DN' suffix typically denotes the TO-3P through-hole package, while 'TU' often indicates tube packaging. The device is designed for general-purpose high-voltage rectification in industrial and consumer electronics.

Diode Arrays Replacement Considerations

Check for equivalents from onsemi or other manufacturers offering similar TO-3P dual common cathode packages with comparable 400V/10A ratings and sub-100ns recovery times.
