MBRF20H200CT

Diode Arrays Overview

The MBRF20H200CT is a dual common-cathode Schottky rectifier manufactured by Taiwan Semiconductor. It features a peak repetitive reverse voltage of 200 V and a continuous forward current rating of 20 A per leg. The device utilizes silicon technology and is housed in an isolated TO-220AB (ITO-220AB) package with three pins. Key electrical characteristics include a maximum forward voltage of approximately 1.05 V at 20 A and a low reverse leakage current of 5 µA at rated voltage. It supports a maximum operating junction temperature of 175 °C and offers high surge current capability.

Diode Arrays Feature Summary

• Dual common-cathode configuration for efficient circuit design
• Guard ring structure provides enhanced overvoltage protection and ruggedness
• Low forward voltage drop contributes to high efficiency and reduced power loss
• Isolated mounting tab facilitates thermal management and electrical isolation

Diode Arrays Applications

• High-frequency inverters
• Freewheeling diode circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific suffix codes on the component marking to confirm compliance status, such as halogen-free or AEC-Q101 qualification, as these attributes depend on the packing code prefix or suffix. Confirm the package type matches the required isolation specifications, as the 'F' designation indicates an isolated tab variant distinct from standard TO-220AB packages. Cross-reference the manufacturer's latest datasheet for any updates to mechanical dimensions or material declarations.

Diode Arrays Selection Notes

Select this component when a dual common-cathode arrangement is required for synchronous rectification or freewheeling paths in medium-power converters. The isolated tab variant is suitable for designs requiring electrical isolation between the heatsink and the cathode potential. Ensure the thermal resistance of the chosen mounting method can handle the power dissipation associated with the 20 A forward current and the specified forward voltage drop at the expected ambient temperature.

Diode Arrays Part Context

This part belongs to the MBR series of high-voltage Schottky barrier rectifiers from Taiwan Semiconductor. The series is designed for general-purpose rectification in switching power supplies and DC-DC converters. The MBRF variant specifically denotes the isolated TO-220AB package, distinguishing it from the standard MBR (TO-220AB) and MBRB (TO-262AA) counterparts within the same electrical specification family.

Diode Arrays Replacement Considerations

Direct pin-compatible replacements with identical electrical ratings include the MBR20H200CT (standard non-isolated tab) and the MBRB20H200CT-1 (TO-262AA package). When substituting, verify that the thermal interface and mounting hardware accommodate the specific mechanical profile of the replacement package, particularly regarding the isolation requirements of the tab connection.
