BTA20-600CWRG

Triacs Overview

The BTA20-600CWRG is a Snubberless Triac manufactured by STMicroelectronics, designed for general-purpose AC switching applications. It features an RMS on-state current of 20 A and supports repetitive peak off-state voltages of 600 V and 700 V. The device utilizes high-performance glass passivated chip technology and employs a clip assembly technique to ensure superior surge current handling capabilities. Key electrical parameters include a maximum gate trigger current (Igt) of 35 mA or 50 mA depending on the specific quadrant operation. The component is housed in a TO-220 package with a voltage-insulated tab rated at 2500 V rms, complying with UL standards.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC suppression networks
• High surge current handling capability due to clip assembly technique
• Voltage insulated tab providing 2500 V rms isolation

Triacs Applications

• Phase control circuits
• Static switching on inductive loads
• Static switching on resistive loads

Triacs Procurement Notes

Verify the specific datasheet revision and exact Igt rating (35 mA vs 50 mA) required for your application quadrant. Confirm that the TO-220 package dimensions and thermal characteristics meet your system's heat dissipation requirements. Ensure the 2500 V rms insulation rating aligns with your safety isolation needs.

Triacs Selection Notes

Select this component when designing AC switches that require robust surge handling without external snubber circuits. The 20 A current rating suits moderate power applications. Consider the 600 V or 700 V voltage variants based on line voltage requirements. Verify compatibility with standard TO-220 mounting hardware and heatsinking solutions.

Triacs Part Context

This part belongs to the BTA series of Snubberless Triacs from STMicroelectronics. The series is characterized by glass passivated chip technology and is suitable for various AC control applications. The BTA20 variant specifically offers a 20 A current capacity, distinguishing it from lower or higher current models within the same family.

Triacs Replacement Considerations

Direct replacements within the STMicroelectronics BTA series with equivalent current and voltage ratings should be considered. Verify pinout compatibility and thermal resistance values when substituting with other manufacturers' triacs.
