Diode Arrays Procurement Notes

Verify the specific suffix 'G' indicates halogen-free compound compliance per IEC 61249-2-21 standards. Confirm RoHS directive alignment for the target market. Check for AEC-Q101 automotive qualification status if required for the application, as standard industrial versions may differ from qualified variants.

Diode Arrays Selection Notes

Select this component for designs requiring robust axial-leaded rectification with super fast recovery speeds. Ensure the circuit operates within the 400V reverse voltage limit and 20A average current rating. Consider the thermal resistance of the DO-201AD package for heat dissipation requirements in enclosed environments.

Diode Arrays Part Context

This part belongs to the UGF series of glass-passivated super fast rectifiers from Taiwan Semiconductor. It shares the same package and general functionality as other members of the family but is distinguished by its specific 400V voltage rating and 20A current capacity, positioning it between lower and higher rated variants.

Diode Arrays Replacement Considerations

Cross-reference with other 20A, 400V super fast rectifiers in the DO-201AD package. Verify pinout compatibility and ensure equivalent or superior reverse recovery time and forward voltage specifications are met by potential substitutes.
