T835H-8G-TR

Overview

The T835H-8G-TR is an 8 A medium current Triac from the H-Series, housed in a D2PAK surface-mount package. It features an 800 V symmetrical blocking voltage and supports a maximum junction temperature of 150 °C. Key electrical parameters include an on-state RMS current of 8 A, a non-repetitive peak on-state current of 84 A, and an on-state voltage of 1.5 V. The device operates with a gate trigger voltage of 1.3 V and a gate trigger current of 35 mA, while maintaining a holding current maximum of 35 mA. It exhibits a low off-state leakage current of 1.5 uA at VDRM and functions within a temperature range of -40 °C to +150 °C.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number T835H-8G-TR with official STMicroelectronics documentation. Confirm the specific suffix indicates the reel packaging format. Ensure compliance with RoHS directives and UL94-V0 flammability standards as specified in the datasheet before integration into production workflows.

Selection Notes

Select this component when designing compact surface-mount circuits requiring reliable control of hard-to-commutate loads. The D2PAK package facilitates heatsink size reduction compared to traditional through-hole options. Ensure the application demands an 800 V rating and 8 A continuous current capacity to fully utilize the device's Snubberless performance characteristics.

Part Context

This Triac belongs to the T835 family, which includes variants like T835T-8G-TR and T835H-8G. The H-Series designation typically denotes specific thermal or packaging optimizations within the broader Snubberless portfolio. These devices are engineered to replace standard Triacs that require external snubber circuits, simplifying the design for AC power control applications.

Replacement Considerations

Direct substitutes within the same series include T835H-8G (tube packaging) and T835T-8G-TR. Verify pinout compatibility and thermal resistance values when transitioning between different package types such as D2PAK and TO-263 to ensure adequate heat dissipation in the final assembly.
