MBR20H100CTH

Diode Arrays Overview

The MBR20H100CTH is a dual common cathode Schottky rectifier manufactured by Taiwan Semiconductor. It features a silicon construction housed in an ITO-220AB (TO-220-3) package with isolated tabs. The device supports a repetitive peak reverse voltage of 100 V and an average forward current of 20 A per diode. Key electrical characteristics include a maximum forward voltage of 850 mV at 20 A and a reverse leakage current of 20 µA at 100 V. The junction temperature range extends from -55°C to +150°C.

Diode Arrays Feature Summary

• Dual common cathode configuration for efficient power conversion
• Guardring technology provides enhanced overvoltage protection
• High surge current capability ensures robust operation under transient conditions
• Low forward voltage drop contributes to high efficiency and reduced power loss

Diode Arrays Applications

• AC/DC switching adapters
• General purpose switching power supplies
• Free wheeling diode applications in DC-DC converters

Diode Arrays Procurement Notes

Verify the specific suffix 'H' on the packing code, as it indicates AEC-Q101 qualification and compliance with JESD 201 class 2 whisker testing standards. Confirm RoHS and halogen-free status via the manufacturer's official datasheet or component marking, as packaging codes determine environmental compliance attributes. Ensure the ITO-220AB package isolation requirements match the target circuit design.

Diode Arrays Selection Notes

Select this component for designs requiring a 100 V rating with 20 A continuous current handling in a through-hole format. The dual common cathode arrangement simplifies bridgeless PFC or synchronous rectification topologies. Verify thermal management capabilities given the 150°C junction limit and ensure the mounting torque does not exceed 5 in-lbs to maintain mechanical integrity.

Diode Arrays Part Context

This part belongs to the MBR20H series of Schottky barrier rectifiers from Taiwan Semiconductor. It shares the 20 A / 100 V specification family with variants like MBR20H100CT and MBR20L100CT. The 'H' suffix specifically denotes automotive-grade reliability features including whisker test compliance, distinguishing it from standard industrial versions.

Diode Arrays Replacement Considerations

Direct substitutes include MBR20L100CTHC0G and MBR20L100CT-C0 from Taiwan Semiconductor, which share identical pinouts and electrical ratings. Cross-manufacturer equivalents such as STPS20H100CT or Vishay MBRB20H100CT-M3/I may require verification of package tolerance and thermal resistance differences.
