Diode Arrays Procurement Notes

Verify the manufacturer status carefully as this component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS directives if applicable to your region. Check for any lifecycle notices indicating obsolescence or limited availability from authorized distributors.

Diode Arrays Selection Notes

Select this component when designing circuits requiring fast recovery times and high voltage blocking capabilities. Consider the thermal resistance of 3.4 °C/W for heat dissipation planning. Evaluate the surge current rating of 30 A against potential transient loads. Ensure the operating junction temperature range of -65 to +150°C aligns with the environmental conditions of the target application.

Diode Arrays Part Context

This part belongs to the FFA series of ultrafast recovery power rectifiers. It shares functional similarities with other devices in the family but is distinguished by its specific current and voltage ratings. The TO-3P package provides a robust mechanical solution for through-hole mounting in industrial and commercial power electronics.

Diode Arrays Replacement Considerations

Direct substitutes may include the FFA10U120DN or FFA20U120DN for higher current requirements within the same voltage class. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers' equivalents.
