BTW69-800RG

Scrs Overview

The BTW69-800RG is a standard SCR thyristor from STMicroelectronics, rated for a maximum repetitive blocking voltage of 800 V and an average on-state current of 50 A. It features a surge current rating of 610 A and a maximum gate trigger current of 80 mA. The device utilizes the TOP3 insulated package, providing high power handling capabilities and superior thermal dissipation. This component is designed for industrial environments requiring robust performance in solid state relays, welding equipment, and high-power motor control applications.

Scrs Feature Summary

• High surge current handling capability based on clip assembly technology
• Internal ceramic pad provides 2500V RMS high voltage insulation
• Complies with UL standards (File ref: E81734) for safety isolation

Scrs Applications

• Solid state relays
• Welding equipment
• High power motor control
• Power converters

Scrs Procurement Notes

Verify the specific suffix 'RG' against official STMicroelectronics documentation to confirm RoHS compliance and halogen-free status. Ensure the TOP3 insulated package type matches the required PCB footprint and mounting constraints. Cross-reference the 800V rating with system voltage requirements to prevent overvoltage failure during operation.

Scrs Selection Notes

Select this component when high surge tolerance and electrical isolation are critical. The TOP3 insulated package is suitable for applications requiring direct heatsink mounting without additional insulators. Compare the 50A continuous current rating against the application's duty cycle and thermal management capabilities to ensure reliable long-term operation under load.

Scrs Part Context

This part belongs to the BTW69 series of standard SCR thyristors from STMicroelectronics. The series shares common design features such as clip assembly technology and internal ceramic insulation. Variants within the series differ primarily by their voltage ratings, such as the BTW69-600 or BTW69-1200, while maintaining similar current handling and packaging characteristics.

Scrs Replacement Considerations

Direct substitutes include other BTW69 series variants with matching voltage ratings, such as the BTW69-800N. Verify that any replacement maintains the TOP3 insulated package form factor and meets the same 2500V RMS isolation requirements for safe integration into existing designs.
