T1635H-6G

Triacs Overview

The T1635H-6G is a Snubberless™ Triac from STMicroelectronics, rated for 16 A RMS on-state current and 600 V repetitive peak off-state voltage. It operates within a junction temperature range of -40°C to +150°C and utilizes a D2PAK surface-mount package. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1 V, and a non-repetitive surge current capacity of 168 A. The device features a low on-state voltage of 1.5 V and a maximum off-state leakage current of 5 µA at VDRM.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber circuits in general-purpose AC switching applications.
• High commutation capability supports reliable operation across three quadrants without external protection components.
• Integrated internal ceramic pad provides 2500 V RMS voltage insulation between the case and the heatsink.

Triacs Applications

• General purpose mains power AC switching
• On/off or phase angle control functions
• AC motor speed control

Triacs Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and manufacturing origin through the manufacturer's latest product data sheets before finalizing procurement orders.

Triacs Selection Notes

Select this component for designs requiring high thermal performance up to 150°C junction temperature. Ensure the gate drive circuit can supply sufficient current to meet the 35 mA trigger requirement. Verify that the load current does not exceed the 16 A RMS rating under all operating conditions.

Triacs Part Context

This part belongs to the H-Series Triacs family, designed for robust AC power control. It shares architectural similarities with other devices in the series but offers specific current and voltage ratings tailored for medium-power industrial and consumer applications.

Triacs Replacement Considerations

Direct replacements must match the 16 A / 600 V rating and D2PAK footprint. Verify pinout compatibility and thermal resistance characteristics to ensure equivalent performance in existing PCB layouts.
