MCC56-16IO1B

Overview

The IXYS MCC56-16IO1B is a single-phase silicon controlled rectifier module designed for high-power industrial applications. It features a TO-240AA package with five pins and panel mounting capability. The device supports a repetitive peak reverse voltage of 1600 V and an RMS on-state current rating of 64 A. It can withstand a surge current of 1.6 kA. Key electrical parameters include a maximum gate trigger current of 100 mA, a maximum gate trigger voltage of 1.5 V, and a peak on-state voltage of 1.57 V. The module operates within a temperature range up to 125°C and has a maximum holding current of 200 mA.

Feature Summary

• Utilizes direct copper-bonded aluminum oxide ceramic baseplate for efficient thermal management.
• Employs vacuum and hydrogen protected welding technology for robust internal connections.
• Features planar passivated chips to ensure stable performance under varying conditions.

Applications

• Industrial heating control systems
• AC/DC motor speed drives
• Uninterruptible power supply (UPS) units

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm pinout and isolation characteristics. Ensure the supplier provides traceability documentation matching the manufacturer's batch records. Confirm that the TO-240AA package dimensions align with the intended mechanical assembly constraints before finalizing orders.

Selection Notes

Select this component when a 64 A RMS current rating at 1600 V blocking voltage is required in a compact form factor. Consider the 1.6 kA surge capacity for applications involving inrush currents. Evaluate the thermal resistance of the TO-240AA package against the system's cooling strategy to maintain junction temperatures within the specified 125°C limit during continuous operation.

Part Context

This part belongs to the IXYS MCC series of thyristor modules, which are engineered for general-purpose power conversion. The series offers various current ratings from 26 A to over 300 A, sharing common packaging standards like TO-240AA and Y1-CU. These modules are widely used in medium-power industrial electronics where reliability and thermal stability are critical.

Replacement Considerations

Direct replacements must match the 1600 V rating, 64 A RMS current, and TO-240AA footprint. Verify gate trigger specifications (Igt/Vgt) to ensure compatibility with existing drive circuits. Cross-reference pin configurations carefully, as variations exist even within similar package types across different manufacturers.
