T630-800W

Overview

The T630-800W is a 6A Snubberless Triac rated for 800V in an ISOWATT220AB package. It features a maximum RMS on-state current of 6A at 105°C case temperature and supports non-repetitive surge peak currents up to 84A at 60Hz. The device operates within a junction temperature range of -40°C to +125°C, with storage limits extending to +150°C. Key electrical parameters include a gate trigger current (IGT) of 30mA maximum, a holding current (IH) of 35mA maximum, and a critical rate of rise of on-state current (dI/dt)c of 50 A/µs. Thermal resistance from junction to case is 3.4°C/W.

Feature Summary

• Snubberless technology providing high commutation performance suitable for inductive loads
• ISOWATT220AB package offering voltage insulation compliant with UL standards

Applications

• Inductive load switching such as rice cookers
• General purpose AC switching circuits

Procurement Notes

Verify the specific ordering suffix matches the required voltage rating of 800V and gate sensitivity of 30mA. Confirm the package type is ISOWATT220AB. Ensure compliance with RoHS directives if applicable to your region. Check for any specific handling requirements related to the plastic housing during assembly.

Selection Notes

Select this component when high commutation capability is required for inductive loads without external snubber networks. The 800V rating suits mains applications requiring higher blocking voltage than standard 600V devices. Consider the 30mA gate sensitivity for logic-level driving compatibility. Evaluate thermal management based on the 3.4°C/W junction-to-case resistance.

Part Context

This part belongs to the T6xxW series of medium current Triacs from STMicroelectronics. It shares the Snubberless architecture with variants like T620-800W but differs in gate sensitivity. The series is designed for value-sensitive appliances needing reliable AC switching. The ISOWATT220AB package provides electrical isolation for safety-critical designs.

Replacement Considerations

Direct substitutes include T620-800W for lower gate sensitivity applications. Other T6xxW series members may serve as alternatives if voltage or current ratings align. Verify pinout compatibility and thermal characteristics before substitution.
