BTA16-800SWRG

Triacs Overview

The BTA16-800SWRG is a Snubberless TRIAC from STMicroelectronics rated for 16 A RMS on-state current and 800 V repetitive peak off-state voltage. It operates within a junction temperature range of -40°C to +125°C and features a maximum gate trigger voltage of 1.3 V with a maximum gate trigger current of 10 mA. The device supports a non-repetitive surge current of 168 A and maintains an on-state voltage of 1.55 V. Packaged in a TO-220 through-hole housing, it includes an internal ceramic pad providing 2500 V RMS insulation.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Integrated insulated tab utilizing internal ceramic pad for electrical isolation
• Logic-level gate sensitivity enabling direct drive from microcontrollers or logic circuits

Triacs Applications

• Static relay switching applications
• Induction motor starting circuits

• Motor speed controllers

Triacs Procurement Notes

Verify the specific suffix 'S' against official STMicroelectronics documentation to confirm the exact gate trigger current rating, as standard variants may differ. Ensure the component matches the required thermal management specifications for the intended application environment.

Triacs Selection Notes

Select this component for AC switching tasks requiring robust handling of inductive load commutation without external snubber networks. The TO-220 package facilitates effective heat dissipation for continuous 16 A operation. Confirm that the 10 mA gate trigger requirement aligns with the driving circuit capabilities.

Triacs Part Context

This part belongs to the BTA16 series of medium-current TRIACs designed for general-purpose mains power AC switching. The series offers both standard and Snubberless versions in various packages, providing flexibility for industrial and consumer electronics applications requiring reliable phase control.

Triacs Replacement Considerations

BTA16-800CWRG: Standard Snubberless variant with potentially different gate trigger characteristics. BTA16-800BWRG: Alternative Snubberless version with distinct gate parameters. Verify pinout compatibility and thermal resistance values before substitution.
