MCMA700P1600NCA
1600 V / 700 A IXYS MCMA phase-leg thyristor module for heavy phase control, electrolysis and large rectifiers.
The MCMA700P1600NCA is a 1600 V / 700 A IXYS thyristor module, configured as a phase leg, for the highest-current phase-control and rectifier applications. A thyristor latches on when it is gated and conducts until the current falls below its holding value, and it handles very high surge currents gracefully, which is why it dominates high-power phase-angle control, heavy motor and transformer soft-start, electrolysis and DC drives, and large rectifiers. The MCMA family offers low on-state voltage with defined dv/dt and di/dt ratings, and the phase-leg configuration builds a full converter bridge from a small number of modules, with an isolated package that mounts on a common heatsink. At 700 A the module suits equipment that carries hundreds of amps continuously and must survive large fault currents. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Designers should confirm the gate drive, the snubber and the thermal design for their line frequency and load. Availability is confirmed per project; BeiLuo reserves supply against your forecast.
FAE Professional Review
The MCMA700P1600NCA is the high-current thyristor module for heavy phase-control and rectifier duty. It shrugs off surge currents that would destroy a transistor, which is exactly why thyristors remain the choice at hundreds of amps. The thermal design and the gate drive are the whole job at this current.

Frequently Asked Questions
When should I choose the 700 A module?
Choose it when the load carries hundreds of amps continuously and must survive large fault currents, such as heavy industrial phase control, electrolysis rectifiers and large DC drives. The phase-leg configuration builds a bridge from a few modules.
For lower current, the MCMA140P1600TA is more economical.
How do I manage 700 A?
Use a busbar with low inductance, keep the connections symmetric, and provide a heatsink that removes the conduction and surge loss. Respect the dv/dt and di/dt ratings and the snubber design for your line frequency.
Our FAE team can review your design.
Is lead time longer for high-current thyristors?
High-current modules can be allocation-managed, so confirm annual volume early. BeiLuo sources through IXYS's authorized channel and reserves supply against your forecast.
