T1635H-6T

Triacs Overview

The T1635H-6T is a Snubberless TRIAC manufactured by STMicroelectronics, rated for 600 V repetitive peak off-state voltage and 16 A RMS on-state current. It features a non-repetitive surge current capability of 168 A and operates within a junction temperature range of -40 °C to +150 °C. The device utilizes a TO-220-3 through-hole package with an internal ceramic insulating pad providing 2500 V RMS isolation. Key electrical parameters include a maximum gate trigger voltage of 1 V, a maximum gate trigger current of 35 mA, and a holding current of 35 mA. The component is RoHS compliant and UL certified.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks in general-purpose AC switching applications.
• High thermal performance allows for reduced heatsink requirements compared to traditional TRIACs due to low thermal resistance clip bonding.
• Internal ceramic insulation pad provides high voltage isolation between the terminal and the mounting surface.

Triacs Applications

• General purpose mains power AC switching
• Motor drive and control systems
• Consumer electronics power regulation

Triacs Procurement Notes

Verify the specific suffix '6T' corresponds to the TO-220AB insulated package variant when sourcing. Confirm RoHS compliance status and UL certification file number E81734 against the latest manufacturer datasheet revision. Ensure the procurement channel provides original packaging to maintain component integrity during storage and handling.

Triacs Selection Notes

Select this component for designs requiring high commutation capabilities in three quadrants without external snubber circuitry. The TO-220-3 package is suitable for automated manufacturing processes requiring through-hole mounting. Consider the 150 °C maximum junction temperature for applications demanding higher thermal margins than standard 125 °C devices.

Triacs Part Context

This part belongs to the STMicroelectronics H-Series Triacs, which are designed for medium current applications up to 20 A. The series offers high switching capability and is available in both through-hole and surface mount packages. The T1635H-6T specifically represents the 16 A, 600 V variant in the TO-220-3 insulated configuration.

Triacs Replacement Considerations

The T1635H-6G is a surface mount alternative in the D2PAK package with identical electrical ratings. Other variants in the T1635H family may offer different voltage or current ratings but share similar Snubberless technology and package options.
