Overview
The IXYS MCC250-14IO1 is a thyristor/diode module featuring a single thyristor and one diode in an international standard package. It has a rated repetitive off-state voltage of 1400 V and a maximum RMS on-state current of 450 A per device. The surge current rating reaches 9600 A at 8.3 ms. Key electrical parameters include a gate trigger current of 150 mA, holding current of 150 mA, and peak forward voltage of 1.36 V at 600 A. Thermal resistance from junction to case is 0.129 K/W per device. The module operates within a junction temperature range of -40°C to +140°C and provides an isolation voltage of 3600 V.
Feature Summary
- Direct copper bonded Al2O3-ceramic base plate for improved thermal cycling
- Planar passivated chips with keyed gate/cathode twin pins
- Isolation voltage of 3600 V~
Applications
- Motor control
- Power converter
- Heat and temperature control for industrial furnaces and chemical processes
- Lighting control
- Contactless switches
Procurement Notes
Verify the specific version suffix against the manufacturer datasheet to confirm the exact voltage rating, as the MCC250 series includes multiple variants. Confirm mounting torque specifications (M5: 2.5-5 Nm; M8: 12-15 Nm) during installation. Check for availability of optional accessories like keyed gate/cathode twin plugs if required for the application design.
Selection Notes
Select this module based on the 1400 V blocking voltage and 450 A RMS current requirements. Ensure the heatsink design accommodates the thermal resistance values provided. Consider the 9600 A surge capability for fault conditions. Verify that the 150 mA gate trigger current matches the driver circuit capabilities.
Part Context
The MCC250-14IO1 belongs to the MCC/MCD 250 series of thyristor modules manufactured by IXYS. This series utilizes an international standard package format. The '14' in the model number indicates a 1400 V rating. The module integrates both a thyristor and a diode in a single unit.
Replacement Considerations
No official substitutes are listed in the documentation. When evaluating alternatives, match the 1400 V rating, 450 A RMS current, and physical dimensions. Verify compatibility with the direct copper bonded ceramic base structure and terminal configurations.
