T1635H-6I

Triacs Overview

The T1635H-6I is a high-temperature Triac from the STMicroelectronics H-Series, rated for 600 V repetitive peak off-state voltage and 16 A average 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 pad providing 2500 V RMS insulation. Key electrical parameters include a maximum holding current of 35 mA, gate trigger voltage of 1 V, and gate trigger current of 35 mA.

Triacs Feature Summary

• Snubberless design optimized for general-purpose AC switching applications
• High thermal performance allowing reduced heatsink requirements at elevated temperatures
• Insulated package variant offering enhanced voltage isolation safety

Triacs Applications

• General purpose mains power AC switching
• Motor drive and control systems
• Consumer electronics requiring robust AC load management

Triacs Procurement Notes

Verify the specific suffix 'I' against official STMicroelectronics documentation to confirm it denotes the insulated TO-220AB package variant. Ensure the procurement channel provides valid RoHS compliance certificates and UL recognition file references. Confirm that the component matches the required 2500 V RMS insulation rating for your specific circuit isolation needs before finalizing orders.

Triacs Selection Notes

Select this component when high commutation capability and operation up to 150 °C are required. The insulated package is suitable where galvanic isolation between the heatsink and circuit ground is necessary. Compare the 35 mA holding current against load requirements to ensure reliable turn-off. Consider the TO-220-3 form factor for through-hole assembly processes in industrial or consumer designs.

Triacs Part Context

This part belongs to the T1635H series of medium-current Triacs designed for high-temperature environments. It shares core electrical characteristics with other variants in the family but differs in packaging and insulation properties. The H-Series designation indicates specialized thermal handling capabilities compared to standard Triacs, enabling more compact thermal management solutions.

Triacs Replacement Considerations

Direct replacements include T1635H-6T (non-insulated) and T1635H-6G (surface mount D²PAK). Verify pinout compatibility and insulation requirements when substituting. Ensure the alternative package supports the same thermal dissipation profile and mounting constraints as the original TO-220-3 insulated design.
