MBRF30H90CT-E3/45

Diode Arrays Overview

The MBRF30H90CT-E3/45 is a dual common-cathode high-voltage Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology for improved high-temperature performance and features a guardring for overvoltage protection. The device is housed in an ITO-220AB package with matte tin-plated leads. Key electrical parameters include a maximum repetitive peak reverse voltage (VRRM) of 90 V, a total maximum average forward rectified current (IF(AV)) of 30 A (15 A per diode), and a peak forward surge current (IFSM) of 275 A. The typical instantaneous forward voltage (VF) is 0.67 V at 15 A, and the maximum reverse current (IR) is 5.0 µA at rated VR. The operating junction temperature range extends from -65 °C to +175 °C.

Diode Arrays Feature Summary

• High Barrier Technology provides enhanced high-temperature performance and lower power losses.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and delivery mode. The E3 suffix indicates consumer grade compliance with JESD 201 class 1A whisker testing. Confirm that the ITO-220AB package matches the design requirements for thermal management and mounting torque specifications before procurement.

Diode Arrays Selection Notes

Select this component when a dual common-cathode configuration is required for high-frequency rectification or freewheeling duties. The ITO-220AB package offers isolation voltage characteristics suitable for heatsink mounting. Ensure the application voltage does not exceed the 90 V rating and that thermal design accommodates the 175 °C maximum junction temperature limit.

Diode Arrays Part Context

This part belongs to the MBR(F,B)30H90CT & MBR(F,B)30H100CT series from Vishay General Semiconductor. The series includes variants in TO-220AB, ITO-220AB, and TO-263AB packages. The MBRF prefix specifically denotes the ITO-220AB package form factor within this product family.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay parts in the MBRB30H90CT or MBR30H90CT series if different package styles are acceptable. Verify pinout compatibility and thermal resistance differences when substituting between TO-220AB, ITO-220AB, and TO-263AB variants.

Diode Arrays FAQ

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

The ITO-220AB package provides an isolation voltage of 1500 VAC from terminal to heatsink for 1 minute.

Does the E3 suffix indicate automotive qualification?

No, the E3 suffix denotes consumer grade which meets JESD 201 class 1A whisker test. Automotive qualification requires the HE3 suffix for AEC-Q101 compliance.

What is the maximum mounting torque allowed?

The maximum mounting torque is 10 in-lbs.
