MBRF2590CT

Diode Arrays Overview

The MBRF2590CT is a dual common-cathode Schottky barrier rectifier manufactured by Taiwan Semiconductor. It features an ITO-220AB package and provides a repetitive peak reverse voltage (VRRM) of 90 V. The device supports a maximum average forward current (IF) of 25 A and a non-repetitive surge forward current (IFSM) of 200 A. Electrical characteristics include a maximum forward voltage of 0.85 V at 12.5 A and 0.92 V at 25 A, both measured at a junction temperature of 25°C. The component operates within a junction temperature range of -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific ordering code suffix when sourcing. The standard part number denotes the base component, while the 'H' suffix indicates AEC-Q101 qualification. Confirm that the procurement matches the required automotive or industrial grade specifications based on the application environment before finalizing orders.

Diode Arrays Selection Notes

Select this component for applications requiring a 90 V blocking voltage and 25 A continuous current handling in an ITO-220AB form factor. Ensure thermal management accounts for the specified junction-to-case resistance. Verify if AEC-Q101 automotive reliability standards are necessary, as this requires the specific 'H' suffix variant rather than the standard commercial version.

Diode Arrays Part Context

This device belongs to the MBRF2535CT through MBRF25150CT series from Taiwan Semiconductor. All members share identical thermal and current ratings but differ in their reverse voltage breakdown capabilities. The series utilizes a dual die configuration within a single plastic molded case to provide two independent rectifying elements with a common cathode terminal.

Diode Arrays Replacement Considerations

Cross-reference with other 25 A, 90 V Schottky rectifiers in the ITO-220AB package. Verify pinout compatibility and ensure equivalent thermal resistance values. Note that generic replacements may lack the specific guard ring overvoltage protection features documented for this series.

Diode Arrays FAQ

What is the maximum forward voltage drop for the MBRF2590CT?

The maximum forward voltage is 0.85 V at 12.5 A and 0.92 V at 25 A, measured at a junction temperature of 25°C.

Does the standard MBRF2590CT meet automotive standards?

No, the standard part does not. Only the variant with the 'H' suffix (MBRF2590CTH) is AEC-Q101 qualified.

What is the thermal resistance from junction to case?

The typical junction-to-case thermal resistance (RθJC) is 1 °C/W.
