T3050H-6G

Overview

The T3050H-6G is a Snubberless Triac from STMicroelectronics, rated for 30 A RMS on-state current and 600 V repetitive peak off-state voltage. It operates within a junction temperature range of -40°C to +150°C and utilizes a D2PAK surface-mount package. Key electrical parameters include a maximum gate trigger current (Igt) of 50 mA, a maximum gate trigger voltage (Vgt) of 1 V, and a maximum holding current (Ih) of 75 mA. The device supports non-repetitive surge currents of 270 A at 50 Hz and 284 A at 60 Hz. It features an internal ceramic pad providing 2500 VRMS isolation.

Feature Summary

• Snubberless technology enabling minimal commutation requirements and high noise immunity up to maximum junction temperature
• Optimized thermal dissipation with low thermal resistance via clip bonding for heatsink size reduction
• High three-quadrant commutation capabilities maintained at elevated temperatures up to 150°C
• Internal ceramic pad providing enhanced voltage insulation

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure the selected variant matches the required mounting style and thermal management constraints for the target application environment.

Selection Notes

Select this component when designing circuits that require robust performance at high junction temperatures without external snubber networks. The D2PAK package is suitable for surface-mount assembly where space efficiency and thermal conductivity are critical. Compare the 30 A rating against the actual load requirements to ensure adequate margin for surge currents during startup or fault conditions.

Part Context

This part belongs to the T3050H H-series of Triacs, which are specifically engineered for high-temperature operation. The series shares common Snubberless technology characteristics but varies in current ratings and packaging options. The T3050H-6G represents the 30 A variant in the D2PAK surface-mount form factor, distinct from through-hole versions like the T3050H-6T.

Replacement Considerations

The T3050H-6G is parameter-equivalent to the T3050H-6G (tube packaging). Verify pinout compatibility and thermal resistance values when substituting with other 30 A, 600 V Snubberless Triacs from different manufacturers.
