CT230802

Overview

The CT230802 is a split dual Silicon Controlled Rectifier (SCR) module manufactured by Powerex Inc. under the POW-R-BLOK series. It features an isolated mounting configuration with a metal baseplate and glass-passivated chips, designed for control and rectification applications. The device contains two separate elements within a six-terminal flange mount package. Key electrical specifications include a typical voltage rating of 800 Volts and a continuous current capacity of 20 Amperes. It supports a maximum on-state current of 20,000 Amperes and a non-repetitive peak on-state current of 400 Amperes. The module exhibits a critical rate of rise of off-state voltage of 500 V/us, a maximum leakage current of 4 mA, and requires a maximum DC gate trigger current of 50 mA at 3 V.

Feature Summary

• Isolated mounting design allows installation on common heatsinks without additional insulators.
• Split dual structure provides four-terminal flexibility for independent control of internal elements.

Applications

• Industrial power control systems requiring isolated SCR modules.
• Rectification circuits utilizing split dual configurations.
• Applications necessitating isolation between the module base and electrical terminals.

Procurement Notes

Verify component authenticity by cross-referencing the part number CT230802 with official Powerex documentation. Confirm compliance with RoHS standards and lead-free status as specified in manufacturer records. Ensure the packaging details match the FLANGE MOUNT, R-XUFM-X6 specification to guarantee correct physical integration and terminal compatibility during procurement.

Selection Notes

Select this component when an isolated dual SCR solution is required for high-current applications. Verify that the 800 Volt rating and 20 Ampere continuous current meet circuit demands. Consider the 6-terminal layout and flange mount style for thermal management and mechanical fit. Ensure gate drive capabilities align with the 50 mA maximum DC gate trigger current requirement.

Part Context

The CT230802 belongs to the POW-R-BLOK family of power modules from Powerex Inc., located in Youngwood, Pennsylvania. This series is engineered for robust performance in industrial environments. The specific model integrates two separate SCR elements into a single isolated package, distinguishing it from standard single-element or non-isolated counterparts within the broader power semiconductor market.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verification of functional equivalents requires consulting official Powerex catalogs or authorized distributor databases for compatible split dual SCR modules with matching voltage, current, and isolation ratings.
