BTB16-800CWRG

Triacs Overview

The BTB16-800CWRG is a Snubberless™ Triac from STMicroelectronics, rated for 16 A RMS on-state current and 800 V repetitive peak off-state voltage. It features a maximum gate trigger current of 35 mA and a peak gate power dissipation of 1 W. The device supports a non-repetitive surge current of 168 A and maintains a holding current of up to 35 mA. Operating within a junction temperature range of -40°C to +125°C, it utilizes a TO-220 package with three pins. Key electrical parameters include a peak on-state voltage of 1.55 V, a maximum gate trigger voltage of 1.3 V, and a repetitive peak off-state leakage current of 5 μA.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Logic level gate sensitivity allowing direct drive from low-power control circuits
• Insulated tab construction providing dielectric isolation between the terminal and mounting surface

Triacs Applications

• General purpose mains power AC switching
• Static relay applications
• Heating regulation systems
• Induction motor starting circuits
• Phase control operation in light dimmers and motor speed controllers

Triacs Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official datasheet specifications. Confirm the specific suffix 'CWRG' corresponds to the required RoHS compliance and packaging format. Request the original data sheet to validate the electrical characteristics match the intended circuit requirements before finalizing procurement decisions.

Triacs Selection Notes

Select this component when designing circuits requiring robust handling of inductive load commutation without external snubber networks. Ensure the gate drive circuit can supply at least 35 mA to guarantee reliable triggering. Verify that the thermal management solution accommodates the TO-220 package dimensions and the expected power dissipation under continuous 16 A operation.

Triacs Part Context

This part belongs to the BTB16 series of 16 A Triacs, which are available in both through-hole and surface-mount packages. The series includes variants with different voltage ratings (600 V, 700 V, and 800 V) and gate sensitivities. The BTB16-800CWRG specifically denotes the 800 V version in a standard TO-220AB package, distinct from the insulated BTA16 variant.

Triacs Replacement Considerations

Direct functional substitutes within the same family include the BTA16-800CWRG, which offers identical electrical performance but includes an electrically insulated tab. Other compatible parts in the series are the BTB16-800BRG and BTA16-800BWRG, though gate trigger current specifications may vary slightly between these sub-types.
