110MT100KB

Overview

The Vishay 110MT100KB is a Generation II three-phase bridge rectifier module rated for 110 A average output current and 1000 V maximum repetitive peak reverse voltage. It features a compact encapsulated design with an electrically insulated case and high thermal conductivity. The device supports a junction temperature range of -40 to 150 °C and provides 4000 V RMS isolation voltage between terminals and the case. Key electrical characteristics include a maximum forward voltage drop of 1.4 V at 150 A and a peak non-repetitive surge current capability of 950 A at 50 Hz.

Feature Summary

• Fully compatible with industry standard INT-A-pak power modules series
• High thermal conductivity package with electrically insulated case
• Offers excellent power volume ratio for easy connection to power transistors and IGBT modules
• UL E78996 approved with 4000 V RMS isolating voltage

Applications

• General purpose industrial power conversion
• Heavy duty rectification applications
• Integration with power transistor and IGBT modules

Procurement Notes

Verify the specific voltage code suffix matches the required VRRM rating, as the MT..KB series spans 800 V to 1600 V. Confirm that the ordering suffix corresponds to the Generation II specification. Ensure mounting hardware and thermal interface materials are selected to meet the specified torque requirements of 4 to 6 Nm for the heatsink interface.

Selection Notes

Select this component when a robust three-phase rectification solution is required for high-current industrial environments. The 110 A rating and 1000 V blocking capability suit medium-to-high power systems. Consider the thermal resistance values and mounting torque specifications during system design to ensure reliable operation within the -40 to 150 °C junction temperature range.

Part Context

This part belongs to the 90-110MT..KB series of power modules from Vishay General Semiconductor - Diodes Division (formerly International Rectifier). The series includes variants with different current ratings (90 A, 110 A) and voltage codes (80 to 160), all sharing the same INT-A-pak compatible mechanical outline and encapsulation technology for standardized integration.

Replacement Considerations

Direct replacements must match the 110 A current rating, 1000 V voltage rating, and INT-A-pak footprint. Verify that alternative three-phase bridge modules offer comparable thermal resistance and isolation voltage specifications to maintain system safety and performance integrity.
