T1635H-600G

Triacs Overview

The STMicroelectronics T1635H-600G is a Snubberless Triac rated for 16 A RMS on-state current and 600 V blocking voltage. Housed in a D2PAK (TO-263) surface-mount package, it supports junction temperatures up to 150°C. Key electrical parameters include a maximum gate trigger current of 35 mA, peak gate power dissipation of 1 W, and non-repetitive surge current capability of 168 A. The device features low thermal resistance via clip bonding and offers high three-quadrant commutation capabilities suitable for general-purpose mains AC switching applications.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks across the main terminals.
• High temperature operation allows junction temperatures to reach 150°C, reducing heatsink requirements.
• Clip bonding technology provides very low thermal resistance for efficient heat dissipation.

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix against official datasheets to confirm voltage rating and package type. Ensure the ordering code matches the required D2PAK configuration and 600V specification. Confirm RoHS compliance status with the manufacturer before finalizing procurement orders.

Triacs Selection Notes

Select this component for designs requiring compact SMD layouts with automated manufacturing compatibility. The 150°C junction rating permits reduced heatsink sizes compared to traditional TRIACs. Verify that the 35 mA gate trigger current aligns with the driving circuit's output capabilities.

Triacs Part Context

This part belongs to the STMicroelectronics H-Series Triacs, which are engineered for high-performance AC switching. The series utilizes internal ceramic pads for insulation in specific packages and is designed to replace larger through-hole components in modern surface-mount PCB designs.

Triacs Replacement Considerations

Direct replacements within the same family include T1635H-6T for through-hole TO-220-3 mounting or T1635H-6G for identical D2PAK specifications. Verify pinout compatibility and thermal characteristics when substituting between package types.
