C358N

Scrs Overview

The C358N is a standard recovery Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc. It features an 800V repetitive peak off-state voltage and a 140A RMS on-state current rating. The device utilizes a TO-200AB (Press-Pak) package configuration with lead-free and RoHS compliant construction. Designed for high-power applications, it supports a maximum operating junction temperature of 125°C and a minimum of -45°C. The component is classified as a single-element thyristor suitable for industrial power control systems.

Scrs Feature Summary

• Standard recovery characteristics optimized for general power switching applications
• Robust TO-200AB Press-Pak mechanical interface for secure mounting
• Lead-free and RoHS compliant manufacturing process

Scrs Applications

• Industrial motor drives and control circuits
• AC power regulation and phase control systems
• General purpose rectification in medium-power converters

Scrs Procurement Notes

Verify the specific suffix against official Powerex documentation to confirm exact electrical tolerances and thermal characteristics. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the delivered units match the specified TO-200AB package dimensions and pinout configuration required for the target application board or heatsink assembly.

Scrs Selection Notes

Select this component when an 800V blocking capability and 140A continuous current handling are required in a standard recovery configuration. The TO-200AB form factor is appropriate for applications requiring robust mechanical clamping and efficient thermal dissipation through a dedicated heatsink interface rather than surface-mount constraints.

Scrs Part Context

The C358N belongs to the Powerex C358 series of silicon controlled rectifiers. This family includes variants with different voltage ratings such as the C358PB (1200V) and C358PD (1400V). All share similar structural designs but differ in their peak voltage specifications, allowing engineers to select the precise voltage rating needed for their circuit isolation requirements.

Scrs Replacement Considerations

Direct cross-replacement requires matching the 800V/140A specification and TO-200AB package. Verify gate trigger parameters and thermal resistance values against original design requirements before substituting with other manufacturers' SCR equivalents.
