The MCMA140P1400TA is a high-voltage thyristor module from IXYS rated for 140A continuous current and 1400V repetitive peak off-state voltage. Engineered for robust SCR-based switching and phase control, this module integrates thyristor elements into a single isolated baseplate package, simplifying thermal management and PCB layout. Its high blocking voltage rating makes it well suited for demanding AC/DC conversion stages where line transients and voltage spikes are a persistent concern. The MCMA140P1400TA meets the performance expectations of engineers designing or maintaining high-power industrial equipment.

Thyristor modules in this current and voltage class are widely deployed across heavy industrial applications including AC motor soft starters, DC motor drives, resistance heating controls, and electrochemical process rectifiers. The MCMA140P1400TA is also found in UPS systems, traction power supplies, and industrial welding equipment where controlled rectification and reliable switching are critical to uptime. Its robust construction handles the thermal cycling and surge conditions common in continuous-duty industrial environments, making it a trusted choice for OEM designs and field replacement alike.

Quick Reference: MCMA140P1400TA

Key Features of the MCMA140P1400TA:

• 1400V repetitive peak off-state voltage (VDRM) for high-line and surge-tolerant applications
• 140A average on-state current (IT(AV)) supporting heavy continuous-duty power loads
• Isolated copper baseplate construction for direct heatsink mounting and efficient thermal dissipation
• Integrated SCR thyristor topology simplifies gate drive circuit design and reduces component count
• Low on-state voltage drop minimizes conduction losses in high-cycle switching applications
• Compatible with standard IXYS module footprints for direct drop-in replacement on existing heatsink assemblies

With a factory lead time of 99 weeks for new production, the MCMA140P1400TA presents a serious procurement challenge for maintenance teams and OEM production lines alike. IXYS modules in this power class are frequently encountered in aging industrial installations where spares inventories have been exhausted and standard distribution channels offer no immediate relief. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time IXYS thyristor modules, providing a direct path to parts that would otherwise require months of waiting or a costly equipment redesign.

ATI Accurate Technology is headquartered in Palmetto, Florida and specializes in power semiconductors including IGBTs, thyristors, diodes, and rectifier modules.
