MBRF2090CT-M3/4W

Diode Arrays Overview

The MBRF2090CT-M3/4W is a dual high-voltage Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a common cathode configuration with two elements housed in an ITO-220AB package. The device supports a maximum repetitive peak reverse voltage of 90 V and provides a total maximum average forward rectified current of 20 A, or 10 A per diode. Key electrical characteristics include a maximum instantaneous forward voltage of 0.80 V at 10 A and 25 °C, and a peak forward surge current capability of 150 A. The component operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Procurement Notes

Verify the specific ordering suffix /4W corresponds to the tube delivery mode containing 50 units per tube as documented in the manufacturer's ordering information. Confirm that the M3 suffix indicates compliance with halogen-free requirements and RoHS directives. Ensure the component meets JESD 201 class 1A whisker test standards before finalizing procurement specifications.

Diode Arrays Selection Notes

Select this component when a dual common cathode Schottky rectifier is required for high-frequency switching applications. The ITO-220AB package offers an isolated base suitable for heatsink mounting. Consider the thermal resistance of 3.5 °C/W per diode for heat dissipation planning. Verify that the 90 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.

Diode Arrays Part Context

This part belongs to the MBRF20xxCT series of dual high-voltage Trench MOS Barrier Schottky Rectifiers from Vishay. The series includes variants with different voltage ratings, such as the MBRF20100CT rated for 100 V. These devices share the same physical footprint and general electrical architecture, differing primarily in their maximum repetitive peak reverse voltage capabilities.

Diode Arrays Replacement Considerations

The MBRF2090CT-E3/4W serves as a verified alternative within the same product family. Both parts utilize the ITO-220AB package and offer identical 90 V and 10 A per diode ratings. Verify that the specific suffixes match the desired packaging format and environmental compliance requirements.
