MCC250-16IO1

Overview

The IXYS MCC250-16IO1 is a dual thyristor module rated for a repetitive peak reverse voltage of 1600 V. It supports an average on-state current of 287 A at a case temperature of 85°C and a root-mean-square current of 450 A. The device features a maximum surge current of 9000 A under standard conditions. Electrical characteristics include a gate trigger current of 150 mA and a holding current of 150 mA. Thermal resistance from junction to case is specified at 0.129 K/W per thyristor. The module utilizes a direct copper bonded Al2O3 ceramic base plate and operates within a junction temperature range of -40°C to +140°C.

Feature Summary

• International standard package with direct copper bonded Al2O3 ceramic base plate

• Isolation voltage rating of 3600 V~
• UL registered component (E 72873)

Applications

• Motor control systems
• Power converter circuits
• Industrial furnace and chemical process heat and temperature control
• Lighting control equipment
• Contactless switches

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm voltage ratings, as variations exist within the MCC250 series. Confirm mounting torque specifications for M5 screws and M8 terminal connections during installation. Ensure thermal interface materials are compatible with the direct copper bonded base plate design to maintain specified thermal resistance values.

Selection Notes

Select this module based on the required 1600 V blocking voltage and 287 A average current capacity at 85°C case temperature. Evaluate thermal management requirements using the provided junction-to-case thermal resistance data. Consider the 9000 A surge current capability for fault protection scenarios. Verify that the application circuitry can supply the necessary gate trigger current of 150 mA.

Part Context

The MCC250-16IO1 belongs to the MCC250 series of thyristor modules manufactured by IXYS. This series includes variants with different voltage ratings, such as 800 V, 1200 V, 1400 V, and 1800 V versions. The module shares common physical dimensions and thermal characteristics with other devices in the MCC250 family, facilitating standardized mechanical integration in power electronics designs.

Replacement Considerations

Direct replacements should be sought from the same MCC250 series or equivalent high-power thyristor modules with matching current and voltage ratings. Verify compatibility with the keyed gate/cathode twin pin configuration if existing wiring harnesses are retained. Ensure the replacement device meets the same isolation voltage and thermal resistance requirements.
