T630-600W

Overview

The T630-600W is a 6A Snubberless™ Triac in the ISOWATT220AB package. It features an RMS on-state current of 6 A at Tc=105°C and a non-repetitive surge peak on-state current of 80 A (50Hz). The device supports a maximum repetitive peak off-state voltage of 600 V, with a gate trigger current (IGT) of 30 mA. Thermal resistance from junction to case is 3.4 °C/W for AC conduction. Operating junction temperature ranges from -40°C to +125°C, while storage temperature spans -40°C to +150°C. The part complies with UL standards under file reference E81734.

Feature Summary

• Snubberless technology providing high commutation performance for inductive loads
• Insulated tab compliant with UL standards

Applications

• Rice cookers
• General purpose mains power AC switching
• Inductive load control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact electrical characteristics and packaging details. Ensure the component meets all required safety certifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring high commutation capabilities without external snubber networks. The 600V rating suits standard mains applications, while the 30mA gate sensitivity requires appropriate drive circuitry. Verify thermal management requirements based on the specified junction-to-case thermal resistance.

Part Context

This Triac belongs to the T6xx series designed for general-purpose AC switching. It utilizes STMicroelectronics' proprietary Snubberless technology to handle inductive loads effectively. The ISOWATT220AB package provides electrical insulation between the terminal and heatsink, simplifying mounting in appliances requiring safety isolation.

Replacement Considerations

Direct replacements include the T620-600W, which shares the same package but has a lower gate trigger current of 20 mA. Higher voltage variants such as the T630-800W are also available within the same series for applications requiring increased blocking voltage capability.
