MCC Series High-Performance SCR Modules in Multiple Specifications MCC19/26/44/56/72/95
The MCC Series high-performance Silicon Controlled Rectifiers (Scrs), also known as thyristors, are available in multiple specifications such asMCC19/26/44/56/72/95. These devices are capable of withstanding high surge currents and blocking high voltages, making them ideal for demanding applications such as phase control, soft-start systems, solid-state relays, and uninterruptible power supplies (UPS). By enabling precise control of conduction timing via gate signals, they facilitate smooth regulation of AC power, serving as the "muscles and nerves" in industrial heating systems, motor speed control, and power conditioning equipment.
A key technological highlight of these modules is the use of Direct Bonded Copper (DBC) substrates. This advanced substrate material bonds a copper layer directly onto ceramic, offering excellent insulation, superior thermal conductivity, and a thermal expansion coefficient close to that of silicon chips. This allows heat generated during conduction to be rapidly and efficiently transferred to the heat sink, significantly reducing the junction temperature of the chips. As a result, the module’s power cycling capability and long-term reliability are greatly enhanced—a critical feature in industrial environments with frequent start-stop cycles or significant load fluctuations.
Structurally, the MCC modules adhere to the classic "M1" industrial standard dimensions. This standardized packaging allows engineers to design thermal and mechanical structures with clear guidelines, facilitating easy replacement or upgrades in existing systems and shortening development cycles. The module’s electrodes feature soldered pins, ensuring robust physical connections and excellent electrical contact with printed circuit boards (PCBs). This design withstands stresses caused by vibration and temperature variations, making the modules highly suitable for integration into power units that demand high reliability.
In terms of electrical performance, the MCC series typically offers average current ratings of several hundred amperes and blocking voltages of several kilovolts. The isolated package design ensures electrical insulation between the mounting base and the circuit, allowing multiple modules to be mounted directly on a single grounded heat sink. This simplifies system design while saving space and cost.
In summary, the IXYS-formfactor MCC Series SCR modules represent a high-performance, highly reliable, and user-friendly high-power control solution. With their DBC soldering technology, M1 standard packaging, and robust structural design, they continue to serve as a cornerstone for efficient and stable power conversion and control—both in traditional industrial retrofits and emerging energy sectors.
