C46N

Scrs Overview

The Powerex C46N is a Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features an 800V repetitive peak off-state voltage and supports a maximum average on-state current of 400A. The device utilizes a TO-200AB (TO-3P) metal case package with stud mounting, ensuring robust thermal dissipation capabilities. Classified as a standard recovery type SCR, it operates within a junction temperature range of -45°C to +125°C. Key electrical characteristics include a non-repetitive peak surge current of 800A and a gate trigger voltage of up to 3V. The component is RoHS compliant and carries an EAR99 classification.

Scrs Feature Summary

• Standard recovery switching characteristic suitable for general-purpose rectification
• Robust metal stud mount construction for efficient heat transfer
• High surge current capability for handling transient load conditions

Scrs Applications

• Industrial motor drives and control systems
• High-power DC power supplies and rectifiers

Scrs Procurement Notes

Verify the specific suffix or variant code against the manufacturer's official datasheet to ensure compatibility with required voltage and current ratings. Confirm that the TO-200AB package dimensions match the intended heatsink interface. Check for RoHS compliance requirements if operating in regulated environments. Ensure proper torque specifications are followed during installation to maintain thermal performance and mechanical integrity.

Scrs Selection Notes

Select this component based on its 800V blocking capability and 400A continuous current rating. Evaluate the thermal resistance of the mounting assembly to ensure the junction temperature remains within the specified limits under worst-case operating conditions. Consider the gate drive requirements, specifically the maximum DC gate trigger voltage, when designing the control circuitry. Verify that the surge current rating exceeds the expected fault currents in the application.

Scrs Part Context

Powerex Inc., now part of Semikron Danfoss, specializes in high-power semiconductor devices. The C46N belongs to their line of silicon controlled rectifiers, which are critical components in power electronics for converting AC to DC.
