Overview
The Powerex T720105504DN is a Silicon Controlled Rectifier (SCR) designed for high-power switching applications. It features a single element configuration housed in a T72 disk button package with three terminals. The device supports a maximum RMS on-state current of 1050 A and a repetitive peak reverse voltage of 500 V. Key electrical characteristics include a gate trigger current of up to 150 mA and a circuit turn-off time of 10 µs. The component operates within a temperature range of -40 °C to 125 °C junction temperature.
Feature Summary
- High current handling capability suitable for industrial power conversion
- Fast circuit commutation for rapid switching cycles
- Robust ceramic-metal sealed disk button construction
Applications
- Industrial motor drives
- Power supply rectification
- Inverter circuits
Procurement Notes
Verify the specific suffix DN against official Powerex documentation to confirm pinout and thermal interface specifications. Ensure the procurement channel provides original manufacturer traceability. Cross-reference the datasheet revision date to validate the 10 µs turn-off time parameter. Confirm compliance with relevant safety standards required for the target installation environment before finalizing orders.
Selection Notes
Select this component when a 500 V blocking voltage and 1050 A RMS current rating are required in a T72 package. Evaluate the 10 µs turn-off time against the system's AC line frequency or switching speed requirements. Consider the 150 mA gate drive capability for driver circuit design. Compare thermal resistance values if multiple packages offer similar electrical ratings.
Part Context
This SCR belongs to the Powerex T72 series, which utilizes a disk button form factor. This series is engineered for high-reliability applications requiring robust mechanical mounting and efficient heat dissipation through the base plate. The T72 case style is standard for medium-to-high power thyristors in industrial settings.
Replacement Considerations
Consult official cross-reference guides for equivalent T72 package SCRs with matching 500 V and 1050 A ratings. Verify that substitute devices maintain identical terminal configurations and thermal characteristics.
