Triacs datasheet and documents for T1635-800G-TR

T1635-800G-TR

Triacs Overview

The T1635-800G-TR is a surface-mount bidirectional triac for AC switching, manufactured by STMicroelectronics. It belongs to the Snubberless™ series and utilizes D2PAK (TO-263) packaging. The device features an 800V repetitive peak off-state voltage and a 16A RMS on-state current. Key electrical parameters include a maximum gate trigger voltage of 1.3V, a maximum gate trigger current of 35mA, and a non-repetitive surge current of 168A. The component operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

Snubberless design allows direct use without external RC snubber circuits when operating within specified limits.
High static dV/dt immunity reduces the risk of false turn-on in noisy environments.
Enhanced dynamic turn-off commutation capability ensures reliable operation with inductive loads.

Triacs Applications

General purpose AC switching
Static relay control
Heating regulation systems

Triacs Procurement Notes

Verify the specific part number against official STMicroelectronics documentation to confirm the 800V rating and D2PAK package configuration. Ensure compatibility with the intended thermal management requirements for the 16A RMS current rating. Confirm that the application respects the defined limits for snubberless operation to maintain device reliability and performance standards.

Triacs Selection Notes

Select this component for applications requiring robust AC load control without the complexity of external snubber networks. The high commutation capability makes it suitable for inductive loads such as motors and transformers. Consider the D2PAK package for efficient surface-mount assembly and adequate heat dissipation for continuous 16A operation in standard ambient conditions.

Triacs Part Context

This device is part of the T1635 family of Snubberless Triacs from STMicroelectronics. The family includes variants with different voltage ratings and packages, such as the T1635-600G-TR for lower voltage applications and the T1635T-8G for higher temperature tolerance up to 150°C. All share the core technology for simplified circuit design and improved reliability in AC power control scenarios.

Triacs Replacement Considerations

Direct substitutes include other STMicroelectronics Snubberless Triacs like the T1635-600G-TR for lower voltage needs or the T1635T-8G for extended temperature ranges. Verify pinout and thermal characteristics when cross-referencing with components from other manufacturers offering similar 16A/800V specifications in D2PAK packages.
