MBR4090PT

Diode Arrays Overview

The MBR4090PT is a Schottky barrier rectifier manufactured by Taiwan Semiconductor Corporation. It features a dual common cathode configuration within a TO-247AD plastic package. The device is rated for a maximum repetitive peak reverse voltage of 90V and an average forward rectified current of 40A per element. Key electrical parameters include a maximum DC blocking voltage of 90V, a forward voltage of 0.85V at 40A, and a non-repetitive peak forward surge current capability of 300A.

Diode Arrays Feature Summary

• Guard ring structure provides enhanced transient protection capabilities
• Utilizes majority carrier conduction to achieve low power loss and high efficiency
• Constructed with molded plastic case material classified as UL Flammability Rating 94V-0

Diode Arrays Applications

• High-frequency switching power supplies
• Free-wheeling diode applications in inductive circuits
• DC-to-DC converters requiring high efficiency

Diode Arrays Procurement Notes

Verify the manufacturer designation on the component marking to confirm it originates from Taiwan Semiconductor Corporation rather than other vendors producing similar part numbers. Ensure the package type matches the required thermal management specifications for the target application environment.

Diode Arrays Selection Notes

Select this component when designing circuits that require a 90V reverse voltage rating combined with a 40A continuous current capacity. The TO-247AD package is suitable for board-level mounting where robust heat dissipation is necessary for high-power Schottky rectification tasks.

Diode Arrays Part Context

This component belongs to the MBR40xxPT series of 40 Amp Schottky Barrier Rectifiers. The series offers various reverse voltage options ranging from 20 Volts to 60 Volts, with the MBR4090PT specifically providing a higher 90V rating while maintaining the same current handling and package form factor.

Diode Arrays Replacement Considerations

Cross-reference with MBR4090 from other manufacturers such as Vishay or Micro Commercial Components. Verify that substitute parts maintain the identical TO-247AD pinout and meet the same 40A/90V electrical ratings.
