- Robust voltage blocking performance up to 400 V in the off-state
- Standard recovery characteristic suitable for general power control
- Stud mount construction for efficient thermal management
Applications
- Industrial motor drives
- Power supply rectification
- Welding equipment inverters
Procurement Notes
Verify the specific suffix 'BY' against official Powerex documentation to confirm exact pinout and mechanical tolerances. Confirm that the TO-209 variant package matches your chassis mounting requirements. Ensure the 400 V rating aligns with your circuit's peak inverse voltage demands. Check for any specific storage or handling guidelines provided in the manufacturer datasheet.
Selection Notes
Select this component when a 250 A RMS current capacity and 400 V blocking voltage are required in a stud-mount form factor. Consider the 150 mA gate trigger requirement for driver circuit design. Evaluate thermal resistance values from the official datasheet to determine appropriate heatsinking solutions for continuous operation at rated currents.
Part Context
This part belongs to Powerex's discrete semiconductor portfolio, specifically within their high-power SCR line. These components are engineered for robust performance in industrial power conversion systems. The TO-209 variant package allows for direct mounting to cold plates or heatsinks, facilitating effective heat dissipation in high-current applications.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the 250 A current rating, 400 V voltage rating, and compatible TO-209 stud mount dimensions.
