BT137-600G0TQ

Triacs Overview

The BT137-600G0TQ is a four-quadrant triac manufactured by WeEn Semiconductors, designed for general-purpose bidirectional switching and phase control applications. It features a sensitive gate structure with a maximum RMS on-state current of 8 A and a repetitive peak off-state voltage rating of 600 V. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 20 mA, a non-repetitive peak on-state current of 71 A, and a typical on-state voltage of 1.3 V. The component is housed in a surface-mount DPAK-3 (TO-252-3) package.

Triacs Feature Summary

• Sensitive gate design for reliable triggering with low gate drive requirements
• Planar passivated construction ensuring high voltage ruggedness and long-term reliability
• Four-quadrant operation capability for versatile AC phase control applications

Triacs Applications

• General purpose bidirectional switching circuits
• AC phase control systems
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix G0TQ against official WeEn Semiconductors documentation to confirm pinout and packaging details. Ensure compatibility with standard SMD reflow profiles for the TO-252-3 package. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement specifications.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required in a compact surface-mount form factor. The sensitive gate characteristic simplifies driver circuit design compared to standard gate devices. Verify thermal management requirements for the DPAK package under continuous load conditions.

Triacs Part Context

This part belongs to the BT137 series of four-quadrant triacs from WeEn Semiconductors. The series includes variants with different packages such as TO-220AB and TO-252. The BT137S-600 variants share similar electrical characteristics but differ in physical mounting style. This model specifically utilizes the surface-mount DPAK configuration.

Triacs Replacement Considerations

Compatible substitutes include the BT137S-600 and BT137-600E/DG, provided the package type matches the PCB layout. Verify that replacement parts maintain the same 8 A RMS current and 600 V voltage ratings.
