C45E

Scrs Overview

The Powerex C45E is a Phase Control Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features an average on-state current rating ranging from 1460 Amperes to 1640 Amperes, depending on the specific variant configuration. The device supports blocking voltages between 500 Volts and 1400 Volts. Key electrical characteristics include a circuit turn-off time of 150 microseconds and a critical rate of rise of off-state voltage of 400 V/µs. Gate triggering requirements specify a maximum DC gate trigger current of 200 mA and a maximum DC gate trigger voltage of 5 V. The component operates at a maximum junction temperature of 125°C.

Scrs Feature Summary

• Engineered for phase control applications requiring high current handling capabilities
• Robust construction supporting high surge currents and rapid voltage transitions
• Optimized gate drive characteristics for reliable triggering in industrial environments

Scrs Applications

• Industrial motor drives and variable speed controls
• High-power rectification systems
• Static power switching for heavy machinery

Scrs Procurement Notes

Verify the specific suffix or sub-model designation when ordering, as ratings for average current and voltage vary across the C45E series variants. Confirm thermal management requirements and mounting hardware compatibility with the selected unit's physical dimensions. Ensure that gate drive circuits match the specified trigger parameters to prevent device failure during operation.

Scrs Selection Notes

Select the appropriate C45E variant based on the required blocking voltage and average current load. Evaluate the system's di/dt and dv/dt stresses against the device's rated limits. Consider the thermal resistance and cooling method necessary to maintain the junction temperature within the specified 125°C maximum limit under continuous operating conditions.

Scrs Part Context

The C45E belongs to Powerex's lineup of high-current phase control SCRs. These devices are typically housed in robust ceramic or metal cases suitable for bolt-down mounting. They are engineered to withstand harsh electrical environments common in heavy industrial power conversion and control systems.

Scrs Replacement Considerations

Direct replacements must match the current and voltage ratings precisely. Cross-reference with other manufacturers' phase control SCRs having similar 1460A-1640A ratings and 500V-1400V blocking capabilities. Verify pinout compatibility and thermal interface specifications before substituting.
