BTB16-800BRG

Triacs Overview

The BTB16-800BRG 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. Key electrical parameters include a maximum gate trigger current (Igt) of 100 mA, a maximum gate trigger voltage (Vgt) of 1.3 V, and a holding current (Ih) of 50 mA. The device supports a non-repetitive surge current of 168 A and exhibits a peak on-state voltage of 1.55 V. It is housed in a TO-220-3 through-hole package.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Logic level gate sensitivity compatible with standard logic outputs
• Integrated internal ceramic pad providing 2500 Vrms insulation between tab and terminals

Triacs Applications

• Static relays and AC switching circuits
• Heating regulation systems
• Induction motor starting circuits
• Phase control operation in light dimmers
• Motor speed controllers

Triacs Procurement Notes

Verify the specific suffix 'BRG' against the manufacturer's official datasheet to confirm compliance with RoHS directives and packaging type. Ensure that the procurement documentation explicitly states the component meets industrial grade specifications and UL 1557 certification requirements where applicable.

Triacs Selection Notes

Select this component when an insulated tab is required for safety isolation without external insulators. The 100 mA gate trigger current allows direct drive from certain logic families. Verify that the 16 A RMS rating and 168 A surge capability are sufficient for the specific load profile and duty cycle of the application.

Triacs Part Context

This part belongs to the BTA16, BTB16, and T16 series of 16 A triacs designed for general-purpose mains power AC switching. The BTB variant specifically denotes a surface-mount or through-hole configuration depending on the exact sub-series, offering low thermal resistance through clip bonding technology for efficient heat dissipation.

Triacs Replacement Considerations

Compatible substitutes within the same family include BTA16-800BRG and BTA16-800BWRG. These alternatives share identical electrical ratings but may differ in package style or specific gate sensitivity characteristics. Confirm pinout compatibility before substitution.
