MCC26-14IO1B

Overview

The IXYS MCC26-14IO1B is a silicon thyristor module designed for high-power phase control applications. It features a single-pole, double-throw (SPDT) configuration with two anti-parallel connected thyristors within one package. The device supports an RMS on-state current of 26 A and offers a rated repetitive peak off-state voltage of 1400 V. Key electrical parameters include a maximum holding current of 200 mA and a gate trigger current of 100 mA. The module operates within a junction temperature range of -40°C to +100°C and utilizes a TO-240AA insulated baseplate package for efficient thermal management and secure screw mounting.

Feature Summary

• Dual anti-parallel thyristor structure enables bidirectional current flow in a compact single module.
• Insulated baseplate design provides electrical isolation between terminals and heatsink.
• Robust mechanical construction supports reliable screw mounting for high-current power circuits.

Applications

• AC motor speed control systems
• Industrial heating and temperature regulation
• Lighting dimmer circuits

Procurement Notes

Verify the specific suffix IO1B against official IXYS documentation to confirm pinout and insulation characteristics. Ensure compatibility with existing PCB or busbar layouts before ordering. Request the latest datasheet from authorized distributors to confirm current production status and any potential obsolescence notices prior to final procurement decisions.

Selection Notes

Select this component when a bidirectional switching solution is required for moderate current loads up to 26 A. The 1400 V rating suits standard industrial AC line voltages. Consider the TO-240AA package dimensions for thermal interface planning. Verify that the gate drive circuit can supply the specified 100 mA trigger current reliably under all operating conditions.

Part Context

This part belongs to the IXYS MCC series of thyristor modules, which are engineered for robust performance in power electronics. The series typically includes variants with different current ratings and voltage classes, sharing common packaging standards like the TO-240AA form factor. These modules are widely used in industrial converters and inverters where reliability and thermal stability are critical.

Replacement Considerations

Direct cross-replacement requires matching the 26 A current, 1400 V voltage, and TO-240AA package. Compare pin configurations carefully as internal wiring may differ. Consult manufacturer substitution guides for equivalent parts from IXYS or other suppliers offering similar SPDT thyristor modules with compatible thermal and electrical specifications.
