MCC500-16IO1 Outline Drawing

The outline drawing of the MCC500-16IO1 power module provides basic information about the physical dimensions, mounting configuration, and terminal layout of the device. The top view highlights three main terminals labeled 1, 2, and 3, which typically correspond to the electrical connections for the power module. The spacing between the terminals is clearly indicated, with a center-to-center distance of 112 mm between terminals 1 and 3. Mounting holes are positioned at all four corners, allowing for secure installation on a heatsink or panel. These holes are sized for M10 bolts, ensuring mechanical stability.

The side view illustrates the overall height of the module, which is approximately 62 mm, and confirms the presence of threaded terminals on top for electrical connections. The drawing also shows a base length of 150 mm and a height clearance of 4 mm at the bottom, which helps with thermal contact and mounting alignment.

The end view provides a look at the control terminals, labeled K and G, typically used for gate and auxiliary control signals in IGBT modules. Together, these views ensure you can confidently integrate the MCC500-16IO1 into your designs by accounting for its physical footprint and interface requirements.

MCC500-16IO1 Internal Circuit Diagram

The internal circuit diagram of the MCC500-16IO1 illustrates its configuration as a dual-diode module. Terminals 1 and 2 represent the cathodes of two power diodes, while terminal 3 is the shared anode. This common-cathode structure allows current to flow from terminal 3 to terminals 1 and 2 through the diodes, providing rectification in high-current applications. The smaller numbered terminals (4, 5, 6, and 7) are auxiliary or sensing connections, typically used for monitoring or snubber networks.

The diagram also shows that terminals 6 and 7 connect internally to the midpoint between the two diodes, indicating potential tap points for thermal or voltage sensing. This setup is common in industrial rectifier blocks, where the module is used in power converters, inverters, or motor drives. The internal layout emphasizes high efficiency and compact integration by combining two high-power diodes in one package with accessible monitoring points.

MCC500-16IO1 Manufacturer

IXYS Corporation was a well-known manufacturer of power semiconductors and integrated circuits, specializing in products such as thyristors, IGBTs, MOSFETs, and gate drivers for industrial, transportation, medical, and consumer markets. Founded in 1983 and headquartered in California, IXYS earned a reputation for providing high-efficiency power solutions designed to improve energy use in switching and power conversion systems. The company focused on reliable, rugged components used in motor drives, solar inverters, UPS systems, and other high-power applications. In 2018, IXYS was acquired by Littelfuse, Inc., which expanded its global reach and product offerings under the Littelfuse brand.
