Overview
The Powerex T820129004DH is a Silicon Controlled Rectifier (SCR) belonging to the T82 series. It features a single element configuration housed in a disk button package with three pins. The device supports surface mount installation and utilizes a ceramic, metal-sealed cofired body material with a round shape. Key electrical ratings include a maximum RMS on-state current of 1657 A and a repetitive peak reverse voltage of 900 V.
Feature Summary
- High current handling capability suitable for heavy-duty power applications
- Robust ceramic and metal-sealed construction for thermal stability
- Surface mount design facilitates automated assembly processes
Applications
- Industrial motor drives
- Power supply rectification
- Inverter circuits
Procurement Notes
Verify the specific suffix DH against official Powerex documentation to confirm pinout and mounting specifications. Ensure compatibility with existing PCB footprints designed for the T82 disk button package. Cross-reference datasheets for thermal resistance values to validate heatsinking requirements for the intended operating environment.
Selection Notes
Select this component when high RMS current capacity and 900V blocking voltage are required in a surface mount form factor. Compare against other T82 variants to match exact current ratings. Verify gate trigger characteristics align with control circuit capabilities. Ensure the disk button package fits within mechanical constraints.
Part Context
This SCR is part of Powerex's T82 series, which offers various current and voltage ratings in a standardized disk button package. The series is designed for high-power applications requiring reliable switching. Other models in the series differ primarily in current handling and voltage ratings while maintaining similar physical dimensions.
Replacement Considerations
Check for direct substitutes within the T82 series with matching 900V and 1657A ratings. Verify pin compatibility and thermal characteristics before substituting with components from other manufacturers.
