Overview
The MCMA140P1800TA is an SCR module manufactured by IXYS, belonging to the MCMA series. It utilizes silicon technology and is housed in a TO-240AA package with screw mount installation. The device features a rated repetitive off-state voltage of 1800 V and an RMS on-state current of 140 A. It supports a non-repetitive peak surge current of 2.59 kA. The maximum gate trigger current is 200 mA, with a maximum holding current of 200 mA. Operating temperatures range from -40 C to +125 C.
Feature Summary
- Employs planar passivated chips for long-term stability
- Utilizes direct copper bonding to aluminum oxide substrate
- Designed specifically for line frequency applications
Applications
- Line frequency power control circuits
- Industrial rectifier systems
- High-power thyristor modules requiring robust thermal management
Procurement Notes
Verify the exact suffix against official datasheets to confirm pinout and electrical ratings. Confirm RoHS compliance status through manufacturer documentation. Check lead times as production cycles may vary. Ensure mounting hardware compatibility with the TO-240AA form factor. Validate thermal interface requirements for the specific application environment.
Selection Notes
Select this component for applications requiring high surge current capability and reliable line frequency operation. Consider the TO-240AA package for standard mounting solutions. Evaluate thermal dissipation needs based on the 140 A RMS rating. Compare gate trigger specifications with available drive circuitry. Assess operating temperature range suitability for the intended environment.
Part Context
This part belongs to the IXYS MCMA series of bipolar thyristor modules. These modules are engineered for high-power industrial applications. The series emphasizes durability through planar chip technology. Direct copper bonding enhances thermal performance. The TO-240AA package provides a standardized footprint for integration into larger power systems.
Replacement Considerations
MCMA140PD1800TB offers similar voltage and current ratings with a diode configuration. MCMA140P1600TA-NI provides comparable performance at a lower voltage rating. Verify pin compatibility and thermal characteristics when substituting.
