Procurement Notes
Verify the specific datasheet version from Powerex Inc. to confirm exact thermal resistance values and mounting torque specifications. Ensure compatibility with existing cooling infrastructure. Check RoHS compliance status if required by project regulations. Confirm lead times directly with authorized distributors as availability may vary.
Selection Notes
Select this component when an 800V blocking voltage and 125A RMS current capacity are required in a stud-mount form factor. Consider the standard recovery time for switching frequency limitations. Evaluate thermal dissipation requirements based on the 80A average current rating and ambient operating conditions.
Part Context
This part belongs to the T50 series of SCRs from Powerex Inc., which are widely used in medium to high-power electronic applications. The TO-94 package provides a standardized mechanical interface for heatsink mounting. The series offers various voltage and current ratings to suit different circuit demands.
Replacement Considerations
Direct substitutes must match the 800V VRRM, 125A IT(RMS), and TO-94 package dimensions. Verify that alternative parts maintain similar gate trigger characteristics and thermal performance. Cross-reference with other manufacturers' T50-style SCRs for mechanical fit.
