MBR3040PT

Diode Arrays Overview

The MBR3040PT is a discontinued Schottky barrier rectifier manufactured by Diodes Incorporated. It features a dual anode common cathode configuration housed in a TO-3P package. The device supports a peak repetitive reverse voltage of 40 V and provides a total average rectified output current of 30 A at a case temperature of 125°C. Electrical characteristics include a non-repetitive peak forward surge current of 200 A, a typical junction-to-case thermal resistance of 1.4 °C/W, and a maximum operating junction temperature range from -65 to +150 °C.

Diode Arrays Feature Summary

• Guard ring die construction designed for transient protection
• Low power loss and high efficiency operation
• High surge current capability with low forward voltage drop

Diode Arrays Applications

• Low voltage, high frequency inverters
• Free wheeling circuits
• Polarity protection applications

Diode Arrays Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verify end-of-life status before design finalization. Sourcing may be limited to surplus channels or require qualification of alternative replacement parts. Confirm RoHS compliance details through official archives if required for regulatory adherence.

Diode Arrays Selection Notes

Select this part only if legacy compatibility is mandatory due to its discontinued status. Evaluate thermal management requirements carefully, as the 30 A rating depends on maintaining a case temperature of 125°C. Consider the 40 V reverse voltage limit and ensure the application does not exceed the specified surge current capabilities during transient events.

Diode Arrays Part Context

The MBR3040PT belongs to the MBR3030PT–MBR3060PT series of 30A Schottky Barrier Rectifiers produced by Diodes Incorporated. This family shares identical mechanical dimensions and general electrical performance profiles, differentiated primarily by their peak repetitive reverse voltage ratings ranging from 30 V to 60 V.

Diode Arrays Replacement Considerations

Public datasheets confirm that MBR3030PT, MBR3035PT, MBR3045PT, MBR3050PT, and MBR3060PT are also discontinued within the same series. No active direct substitutes are listed in the provided documentation.
