Overview
The MCMA140PD1800TB is a bipolar thyristor module manufactured by IXYS, designed for high-power line frequency applications. It features a TO-240AA-3 screw-mount package with five pins. Key electrical ratings include a repetitive peak reverse voltage of 1.9 kV and a forward voltage drop of 1.63 V. The device operates within a temperature range of -40°C to +125°C, with a maximum power dissipation of 520 W. Gate triggering current is specified at 200 mA, while the holding current maximum is also 200 mA.
Feature Summary
- Integrates planar passivated chips for long-term stability
- Utilizes direct copper bonding on aluminum oxide substrate
- Designed for robust performance in line frequency applications
Applications
- Industrial motor drives
- High-power rectifier circuits
- Line frequency thyristor control systems
Procurement Notes
Verify the specific suffix 'TB' against the official datasheet to confirm terminal configuration and material specifications. Ensure thermal interface materials are compatible with the screw-mount TO-240AA-3 package. Confirm that gate drive circuits can supply the required 200 mA trigger current. Validate operating temperatures remain within the -40°C to +125°C range during installation.
Selection Notes
Select this component when a 1.9 kV blocking voltage and 140 A RMS current rating are required in a standard TO-240AA footprint. Consider the 1.63 V forward voltage for thermal management calculations. Compare against similar IXYS models like MCMA140PD1600TB if lower voltage ratings suffice. Ensure the application environment supports the specified power dissipation limits without excessive cooling requirements.
Part Context
This part belongs to the IXYS MCMA series of discrete semiconductor modules. The series utilizes silicon technology and is categorized under SCR modules. It shares the TO-240AA package form factor with other variants in the lineup, such as the MCMA140P1800TA, though terminal configurations may differ based on the suffix.
Replacement Considerations
MCMA140PD1600TB is a verified substitute with identical packaging and current ratings but a lower 1600 V reverse voltage rating. Verify that the system voltage does not exceed 1600 V before substitution.
