MMO90-16IO6

Overview

The IXYS MMO90-16IO6 is a silicon-controlled rectifier (SCR) module designed for high-power industrial applications. It features an anti-parallel configuration with two elements housed in a MINIBLOC-4 package. The device supports a maximum repetitive peak reverse voltage of 1600V and a root-mean-square on-state current rating of 90A. Key electrical characteristics include a non-repetitive peak forward current capability of 1250A and a holding current of 100mA. The component utilizes screw terminals for secure mounting and offers an isolated case connection, facilitating integration into thermal management systems.

Feature Summary

• Anti-parallel dual-element configuration for bidirectional control
• Isolated case connection for enhanced safety and heat dissipation
• Robust mechanical design with screw terminal interfaces

Applications

• Industrial motor drives and AC power control systems
• High-power rectification circuits in energy conversion equipment
• Static switch applications requiring robust surge handling

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging and terminal configurations. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Cross-reference the manufacturer part number with Littelfuse equivalents if applicable, as IXYS power semiconductor assets are managed under Littelfuse. Ensure that the selected variant matches the exact voltage and current ratings required for the target circuit design.

Selection Notes

Select this module based on its 1600V blocking capability and 90A continuous current rating for demanding power electronics environments. The MINIBLOC-4 package provides a compact footprint suitable for space-constrained industrial enclosures. Consider the thermal resistance characteristics when designing heatsinking solutions. Verify that the gate trigger requirements align with the driving circuit's output capabilities to ensure reliable switching performance under varying load conditions.

Part Context

This component belongs to the MMO series of SCR modules from IXYS, now part of Littelfuse. The series is engineered for high reliability in industrial power applications. The MMO90-16IO6 specifically addresses needs for medium-to-high power AC control where robust surge immunity and efficient thermal transfer are critical. It represents a standard solution for replacing older discrete thyristor assemblies in modernized power conversion hardware.

Replacement Considerations

Direct replacements may include other IXYS/Littelfuse MINI-BLOC series SCRs with matching 1600V/90A ratings. Verify pinout compatibility and thermal interface dimensions before substitution. Generic equivalents must meet or exceed the original specifications for voltage, current, and package style.
