T835-600G

Overview

The T835-600G is an 8 A Snubberless Triac manufactured by STMicroelectronics, housed in a surface-mount TO-263 package. It features a repetitive peak off-state voltage of 600 V and supports a surge current rating of 84 A at 50 Hz. The device operates with a maximum gate trigger current of 35 mA and a gate trigger voltage of 1.3 V, while maintaining a peak on-state voltage of 1.55 V. Designed for robust performance, it withstands junction temperatures up to 150 °C and offers a holding current of 35 mA. This component is part of the Snubberless T8 Series, optimized for high commutation capabilities without external snubber circuits.

Feature Summary

• Snubberless design enables direct operation on inductive loads without requiring external RC snubber circuits
• High static dV/dt and dynamic commutation performance ensures reliable switching in demanding environments
• Logic level interface allows direct connection to low power drivers such as microcontrollers

Applications

• Static relays for general purpose AC switching
• Heating regulation systems
• Induction motor starting circuits
• Phase control operation in light dimmers
• Motor speed controllers

Procurement Notes

Verify the specific suffix 'G' against official STMicroelectronics documentation to confirm pinout and thermal characteristics. Ensure the TO-263 footprint matches your PCB layout requirements. Cross-reference datasheet limits for gate trigger parameters to validate driver compatibility. Confirm RoHS compliance status through the manufacturer's latest release notes before finalizing procurement.

Selection Notes

Select this component when high commutation capability is required for inductive loads without adding external snubber circuitry. The TO-263 package suits applications needing surface-mount assembly with adequate thermal dissipation. Verify that the 600 V blocking voltage meets the peak line voltage requirements. Ensure the driving circuit can supply the specified 35 mA gate trigger current reliably across the operating temperature range.

Part Context

The T835-600G belongs to the T835 family of 8 A Snubberless Triacs from STMicroelectronics. This series includes variants like the T835T-8I and T835H-8I, which offer similar electrical ratings but differ in packaging and temperature specifications. The T835 series is engineered for general-purpose AC switching, providing enhanced noise immunity and turn-off commutation compared to standard triacs.

Replacement Considerations

The T835-600G-TR is a tape-and-reel variant of the same component. Other family members include the T835T-8I in a through-hole package. Verify pinout compatibility and thermal resistance differences when substituting with other manufacturers' parts.
