MCD95-18IO1B

Overview

The MCD95-18IO1B is a silicon thyristor module manufactured by IXYS, designed for high-power industrial applications. It features a TO-240AA screw-mount package and supports an output current of 95 A with a maximum repetitive peak reverse voltage of 1800 V. The device operates within a temperature range of -40 °C to +125 °C and includes a forward voltage drop of 1.5 V at rated conditions.

Feature Summary

• High-voltage blocking capability suitable for demanding power conversion environments
• Robust thermal management through direct screw-mount installation on heatsinks
• Integrated anti-parallel diode configuration for efficient rectification and inversion

Applications

• Industrial motor drives and variable frequency drives
• High-power DC-AC inverters and UPS systems
• Static switchgear and soft-start circuits for heavy machinery

Procurement Notes

Verify the specific suffix 'B' against the official IXYS datasheet to confirm pinout and internal configuration, as variations exist within the MCD95 series. Ensure the supplier provides traceability documentation matching the manufacturer's lot codes. Cross-reference the part number with authorized distributors to avoid counterfeit components in critical power electronics assemblies.

Selection Notes

Select this component when a 95 A RMS current rating and 1800 V blocking voltage are required in a compact TO-240AA form factor. Consider the 1.5 V forward voltage drop for thermal design calculations. Verify gate trigger requirements against the control circuit capabilities. Ensure the application environment stays within the specified -40 °C to +125 °C operating temperature range for reliable performance.

Part Context

This module belongs to the IXYS MCD95 series of discrete semiconductor modules, which are widely used in medium-to-high power industrial converters. The series offers various voltage ratings from 800 V to 1800 V, allowing designers to select appropriate blocking voltages while maintaining consistent mechanical mounting dimensions and thermal characteristics across the product line.
