MCC501-18IO2

Overview

The MCC501-18IO2 is a silicon SCR module manufactured by IXYS, belonging to the MCC501 series. It features a dual thyristor configuration designed for high-power applications. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 1.8 kV and a maximum holding current (Ih) of 300 mA. The device operates within a temperature range of -40°C to +125°C. Gate triggering specifications specify a maximum gate trigger voltage (Vgt) of 2.5 V and a gate trigger current (Igt) of 250 mA. The component utilizes standard bulk packaging.

Feature Summary

• Dual thyristor structure for bidirectional or bridge circuit configurations
• High voltage blocking capability suitable for industrial power systems
• Robust thermal performance across extended operating temperatures

Applications

• Industrial motor drives and control systems
• High-voltage DC power transmission equipment
• Static VAR compensators and reactive power compensation

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon order confirmation, as this component may be subject to long-lead times or end-of-life status. Confirm RoHS compliance details directly with the supplier, as regulatory status can vary by production batch. Ensure that the purchasing channel provides authentic manufacturer documentation to avoid counterfeit components in critical power electronics assemblies.

Selection Notes

Select this module when a dual thyristor arrangement is required for high-voltage AC control or rectification. The 1.8 kV rating suits medium-to-high voltage industrial networks. Verify that the gate drive circuit can supply at least 250 mA to ensure reliable turn-on. Consider thermal management requirements given the 125°C maximum junction temperature limit and the specific mounting constraints of the bulk package form factor.

Part Context

This part belongs to the IXYS MCC501 series of discrete SCR modules. The series is characterized by silicon planar chip technology and is designed for line-frequency applications. Similar parts in the family include variations with different voltage ratings such as the MCC501-16IO2 and MCC501-22IO1, allowing designers to scale voltage capabilities while maintaining consistent mechanical and thermal interface standards.

Replacement Considerations

No official direct substitutes are listed in public documentation. Cross-compatibility requires matching the 1.8 kV VDRM, 300 mA Ih, and dual thyristor topology. Verify pinout compatibility and thermal resistance values before substituting with other manufacturers' dual SCRs.
