MBR4030PT

Diode Arrays Overview

The MBR4030PT is a discontinued Schottky barrier rectifier manufactured by Diodes Incorporated. It features a TO-3P case with a maximum average rectified output current of 40 A at a case temperature of 125°C and a peak repetitive reverse voltage of 30 V. The device utilizes a guard ring die construction for transient protection and offers a typical forward voltage drop of 0.70 V at 20 A and 25°C. It supports a non-repetitive peak forward surge current of 400 A and operates within a junction temperature range of -65°C to +150°C.

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 availability through authorized distributors and assess long-term supply chain risks associated with discontinued semiconductor devices.

Diode Arrays Selection Notes

Select this part only if legacy compatibility is required, as it is no longer in production. Evaluate thermal management requirements carefully, noting the 40 A rating applies specifically at a 125°C case temperature. Consider derating curves for lower ambient conditions. Ensure the 30 V reverse voltage rating meets circuit specifications. Review mechanical dimensions for TO-3P mounting constraints.

Diode Arrays Part Context

The MBR4030PT belongs to the MBR4030PT-MBR4060PT series of 40A Schottky barrier rectifiers from Diodes Incorporated. This family shares identical physical packaging and general electrical characteristics, differing primarily in their maximum repetitive reverse voltage ratings which range from 30 V to 60 V across the series variants.

Diode Arrays Replacement Considerations

As the part is discontinued, verify functional equivalents with matching TO-3P packaging, 40 A current rating, and 30 V reverse voltage. Cross-reference datasheets for forward voltage and thermal resistance parameters to ensure circuit performance compatibility.
