T3050H-6T

Overview

The STMicroelectronics T3050H-6T is a 30 A, 600 V H-series triac designed for high-temperature operation up to 150 °C. It utilizes Snubberless technology to ensure minimal commutation requirements and high noise immunity at maximum junction temperature. The device features low thermal resistance via clip bonding and provides 2500 VRMS insulation through an internal ceramic pad. Key electrical parameters include a maximum gate trigger current of 50 mA, a holding current of 75 mA, and a non-repetitive surge current rating of 284 A.

Feature Summary

• Snubberless design enabling simplified circuit topology without external RC networks
• High thermal efficiency with low thermal resistance achieved through clip bonding
• Enhanced noise immunity and reliable commutation across three quadrants at elevated temperatures

Applications

• Control of universal motors in power tools
• Inductive load switching in major household appliances
• AC power control systems requiring high thermal stability

Procurement Notes

Verify the specific suffix '6T' corresponds to the TO-220AB package variant when sourcing. Confirm RoHS compliance status and UL certification file E81734 validity during procurement. Ensure the supplier provides official datasheets matching the T3050H series specifications to avoid substitution errors with similar part numbers.

Selection Notes

Select this component for applications demanding robust performance at junction temperatures up to 150 °C. The Snubberless feature reduces bill-of-materials complexity by eliminating external snubber circuits. Verify that the required RMS current does not exceed 30 A and that the voltage rating of 600 V aligns with the system's peak blocking voltage requirements.

Part Context

The T3050H-6T belongs to the T3050H H-series family of high-current triacs from STMicroelectronics. This series is engineered specifically for environments where thermal management is critical. The device shares core technological attributes with other members of the H-series, such as enhanced commutation capabilities and optimized thermal dissipation structures.

Replacement Considerations

Publicly confirmed substitute part number: Q6035RH5TP (Littelfuse Inc.). Verify pinout compatibility and thermal characteristics before implementation.
