MBR30H35CTHE3/45

Diode Arrays Overview

The MBR30H35CTHE3/45 is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor. It utilizes High Barrier Technology to enhance high-temperature performance and reliability. The device features a maximum repetitive peak reverse voltage of 35 V and supports a total maximum average forward rectified current of 30 A, with 15 A per diode. It operates within a junction temperature range of -65 °C to +175 °C and is housed in TO-220AB, ITO-220AB, or TO-263AB packages.

Diode Arrays Feature Summary

• High Barrier Technology for improved high-temperature performance
• Guardring structure provides overvoltage protection
• Low forward voltage drop for lower power losses and high efficiency
• AEC-Q101 qualified for automotive applications

Diode Arrays Applications

• Low voltage, high frequency rectifiers in switching mode power supplies
• Freewheeling diodes in DC/DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific package variant (TO-220AB, ITO-220AB, or TO-263AB) required for your design, as the base part number covers multiple mechanical options. Confirm that the HE3 suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure thermal management aligns with the specified junction-to-case thermal resistance values for the chosen package type during operation.

Diode Arrays Selection Notes

Select this component when low forward voltage drop and high surge capability are critical for system efficiency. The AEC-Q101 qualification makes it suitable for automotive environments requiring robust high-temperature operation up to 175 °C. Consider the specific package dimensions and mounting torque requirements (maximum 10 in-lbs) during PCB layout and mechanical assembly planning.

Diode Arrays Part Context

This device belongs to the MBR30HxxCT series of dual common cathode Schottky rectifiers from Vishay. The series includes variants with different reverse voltage ratings, such as 45 V, 50 V, and 60 V. The HE3 suffix denotes an AEC-Q101 qualified, RoHS-compliant version, distinguishing it from the commercial grade E3 suffix variants within the same family.

Diode Arrays Replacement Considerations

Direct substitutes include other MBR30HxxCTHE3/45 variants with higher reverse voltage ratings (e.g., MBR30H45CTHE3/45, MBR30H50CTHE3/45, MBR30H60CTHE3/45), provided the circuit voltage does not exceed 35 V. Verify package compatibility if replacing between TO-220AB, ITO-220AB, and TO-263AB footprints.
