MCMA700PD1600CB

Overview

The MCMA700PD1600CB is a silicon SCR module from the IXYS MCMA series, designed for high-power thyristor applications. It features a ComPack package with screw mount installation. Key electrical parameters include an RMS on-state current of 700 A and a rated repetitive off-state voltage (VDRM) of 1.6 kV. The device supports a non-repetitive on-state current of 19 kA and a maximum breakover current (IBO) of 20.5 kA. On-state voltage is specified at 1.16 V, with a gate trigger voltage of 2 V and current of 300 mA. Leakage current in the off state is limited to 2 mA at VDRM. Operating temperatures range from -40 C to +125 C.

Feature Summary

• High current capacity with 700 A RMS on-state rating for robust power handling
• High voltage blocking capability with 1.6 kV rated repetitive off-state voltage
• Integrated gate control requiring 2 V trigger voltage and 300 mA trigger current
• Thermal resilience supporting operation up to +125 C junction temperature

Applications

• Industrial motor drives and variable frequency drives
• High-power DC-DC converters and power supplies
• Static power switching and rectification systems
• HVDC transmission and flexible AC transmission systems

Procurement Notes

Verify the specific suffix CB against the manufacturer datasheet to confirm exact pinout and mechanical dimensions. Confirm RoHS compliance status through official documentation before integration. Check for lead-free plating requirements if applicable to your assembly process. Ensure thermal interface materials are compatible with the ComPack baseplate design. Validate that gate drive circuits can supply the required 300 mA trigger current reliably.

Selection Notes

Select this component when high RMS current and 1.6 kV blocking voltage are required in a compact form factor. Compare the 700 A rating against peak load currents to ensure adequate margin. Consider the 1.16 V on-state voltage for conduction loss calculations. Evaluate the 19 kA surge capability against potential fault conditions. Verify that the screw mount style fits the available heatsink infrastructure.

Part Context

This part belongs to the IXYS MCMA series of bipolar thyristor modules. These modules utilize silicon technology for high reliability in industrial environments.
