Diode Arrays Procurement Notes

Verify component authenticity against official Vishay documentation before integration. Confirm that the specific ordering suffix matches the required package type and compliance standards. Ensure thermal management aligns with the specified junction-to-case resistance values. Validate that the application environment remains within the defined operating temperature limits to maintain performance specifications.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or free-wheeling duties. The ITO-220AB package facilitates efficient heat dissipation compared to smaller surface mount alternatives. Consider the 60 V rating for systems requiring higher blocking voltages than standard 45 V variants. Evaluate thermal derating curves to ensure continuous current capacity meets circuit demands at elevated case temperatures.

Diode Arrays Part Context

This part belongs to the MBRF20xxCT series of dual Schottky barrier rectifiers designed for high-efficiency power conversion. The 'E3' suffix indicates RoHS compliance and halogen-free material composition. Vishay manufactures these devices using platinum barrier metal technology to achieve superior switching characteristics and reduced reverse recovery charge compared to conventional silicon rectifiers.

Diode Arrays FAQ

What is the isolation voltage specification for the ITO-220AB package?

The isolation voltage from terminal to heatsink is 1500 V AC for a duration of one minute.

How does the forward voltage drop change with temperature?

The maximum instantaneous forward voltage decreases as temperature increases; for example, it drops from 0.80 V at 25 °C to 0.70 V at 125 °C at an IF of 10 A.

Is the MBRF2050CT-E3/45 qualified for automotive applications?

No, the E3 suffix denotes commercial grade. Automotive qualification requires the HE3 suffix under the AEC-Q101 standard.
