Diode Arrays Procurement Notes

Verify that the ordering code includes the 'H' suffix to confirm AEC-Q101 qualification status. Ensure the component is sourced from authorized channels to guarantee compliance with RoHS directives and halogen-free requirements per IEC 61249-2-21. Cross-reference the marking code on the physical device against the manufacturer's documentation to validate authenticity and specific voltage rating.

Diode Arrays Selection Notes

Select this component when a 90 V reverse voltage rating is required alongside a 25 A continuous current capacity in a surface-mount compatible leaded package. The AEC-Q101 qualification makes it appropriate for automotive applications where higher reliability standards are mandated compared to standard industrial components. Consider the thermal resistance values for heat sink design in high-power environments.

Diode Arrays Part Context

This part belongs to the MBRF25xCT series manufactured by Taiwan Semiconductor Corporation. The series encompasses various voltage ratings ranging from 35 V to 150 V, all sharing identical current ratings and package dimensions. The 'H' suffix specifically denotes AEC-Q101 qualification, distinguishing it from the standard MBRF2590CT variant which lacks automotive certification.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBRF2535CT, MBRF2545CT, MBRF2550CT, MBRF2560CT, MBRF25100CT, and MBRF25150CT, provided the voltage rating matches the application requirements. Other manufacturers offering equivalent 25 A, 90 V Schottky rectifiers in the ITO-220AB package may be considered if electrical parameters align.

Diode Arrays FAQ

What does the 'H' suffix indicate in the MBRF2590CTH ordering code?

The 'H' suffix indicates that the device is qualified according to the AEC-Q101 automotive electronic council standard.

What is the maximum non-repetitive forward surge current for this device?

The maximum non-repetitive forward surge current is 200 A, measured as an 8.3 ms single half sine wave superimposed on the rated load.

How does the forward voltage change with temperature?

The forward voltage decreases as temperature increases; for example, the maximum forward voltage drops from 0.85 V at 25°C to 0.75 V at 125°C when tested at 12.5 A.
