C782LE

SCRs - Modules Overview

The Powerex C782LE is a Phase Control Silicon Controlled Rectifier (SCR) designed for high-power industrial applications. It features an average on-state current of 2300 Amperes and a repetitive peak off-state voltage of 2500 Volts. The device utilizes a disk button package with a ceramic, metal-sealed cofired body. Key electrical characteristics include a circuit commutated turn-off time of 250 µs, a maximum DC gate trigger current of 250 mA, and a maximum DC gate trigger voltage of 4.5 V. It supports a non-repetitive peak on-state current of 35000 A and operates within a temperature range of -40 °C to 125 °C.

SCRs - Modules Procurement Notes

Verify the specific suffix 'LE' against official Powerex documentation to confirm exact voltage and current ratings, as suffixes often denote specific blocking voltage grades or testing criteria. Ensure compatibility with existing heatsinking and gate drive requirements before procurement.

SCRs - Modules Selection Notes

Select this component based on the required 2300 A average current and 2500 V blocking voltage. Confirm that the gate trigger parameters (250 mA max, 4.5 V max) align with the available drive circuitry. Verify the disk button package dimensions for mechanical integration.

SCRs - Modules Part Context

The C782LE belongs to the Powerex C782 series of high-power phase control SCRs. This series is characterized by large disk packages designed for high thermal dissipation and robust performance in demanding power electronics environments.

SCRs - Modules Replacement Considerations

Check for direct cross-reference part numbers from Powerex or other manufacturers offering identical 2300 A / 2500 V disk button SCRs. Ensure pinout and mechanical dimensions match exactly.
