T3050H-6I

Overview

The T3050H-6I is a 30 A, 600 V H-series Triac from STMicroelectronics, housed in an insulated TO-220 package. It supports junction temperatures up to 150°C and features Snubberless technology for high noise immunity. Key electrical parameters include a maximum gate trigger current of 50 mA, a maximum holding current of 75 mA, and a surge current rating of 284 A. The device operates within a temperature range of -40°C to +150°C.

Feature Summary

• Snubberless design with high noise immunity levels valid up to maximum junction temperature
• Internal ceramic pad providing 2500 VRMS voltage insulation
• Low thermal resistance achieved through clip bonding technology
• High three-quadrant commutation capabilities at elevated temperatures

Applications

• Control of universal motors in power tools
• Inductive load control in major appliances
• General purpose mains power AC switching

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. Ensure that any additional characters in the part number do not indicate variations in electrical ratings or packaging formats before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high thermal performance and reduced heatsink size due to operation at 150°C. The Snubberless feature simplifies circuit design by eliminating external RC networks, making it suitable for compact applications where space and cost efficiency are critical compared to electromechanical solutions.

Part Context

This device belongs to the T3050H H-series, which includes variants like T3035H-6I and T3050H-6T. These triacs share core technologies such as Snubberless capability and high-temperature operation but differ in packaging (TO-220 vs TO-220AB) and specific gate trigger characteristics defined by their suffixes.

Replacement Considerations

Consider T3035H-6I for similar performance in TO-220 packages with slightly different gate trigger currents. For surface mount requirements, evaluate the T2050H series, though current ratings and package types differ significantly.
