BTB16-800SWRG

Triacs Overview

The BTB16-800SWRG is a Snubberless™ Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an RMS on-state current rating of 16 A and a repetitive peak off-state voltage (VDRM) of 800 V. The device supports a non-repetitive surge current of 168 A and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger current (Igt) of 10 mA, a maximum holding current (Ih) of 15 mA, and 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 with low gate trigger current requirements
• Insulated tab construction providing 2500 V RMS isolation compliance

Triacs Applications

• Static relays and AC power 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 'WRG' against official STMicroelectronics documentation to confirm RoHS compliance and packaging details. Ensure the procurement channel provides valid traceability for industrial-grade components. Cross-reference the part number with the latest datasheet revision to confirm active status and any potential process change notifications before finalizing orders.

Triacs Selection Notes

Select this component for applications requiring robust handling of inductive load commutation without external snubber networks. The 800 V voltage rating suits standard mains voltage environments. Consider the TO-220-3 package for thermal management needs and verify that the 10 mA gate drive capability matches the control circuit output specifications.

Triacs Part Context

This device belongs to the BTA16, BTB16, and T16 series of 16 A Triacs from STMicroelectronics. The BTB variant specifically denotes the TO-220AB package configuration. These components are engineered for medium-current AC switching tasks, offering a balance of high current handling and reliable gate triggering characteristics for industrial and consumer electronics.

Triacs Replacement Considerations

Direct functional substitutes within the same series include BTA16-800CWRG and BTA16-800BWRG. Verify pinout compatibility and exact electrical tolerances when substituting between BTA and BTB packages due to potential differences in insulation ratings.
