BT137X-600F,127

Triacs Overview

The BT137X-600F,127 is a four-quadrant triac manufactured by WeEn Semiconductors. It features an RMS on-state current rating of 8 A and a repetitive peak off-state voltage of 600 V. The device supports a non-repetitive surge current of 71 A and operates within a junction temperature range of -40°C to +125°C. Electrical characteristics include a maximum gate trigger voltage of 700 mV and a maximum holding current of 20 mA. It is housed in a TO-252 (DPAK) surface-mount package.

Triacs Feature Summary

• Four-quadrant sensitive gate operation for reliable triggering across all polarity combinations.
• Planar passivated construction designed for general-purpose bidirectional switching applications.
• Surface-mount DPAK packaging optimized for automated PCB assembly processes.

Triacs Applications

• General purpose bidirectional switching circuits
• Phase control applications
• Lighting dimmer implementations

Triacs Procurement Notes

Verify the specific suffix '127' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required surface-mount footprint and thermal management constraints for the target design environment.

Triacs Selection Notes

Select this component when an 8 A RMS current capacity and 600 V blocking voltage are required in a compact surface-mount form factor. Confirm that the 700 mV gate trigger voltage aligns with the driving circuit capabilities and that the DPAK package thermal resistance meets the system's heat dissipation requirements.

Triacs Part Context

This part belongs to the BT137 series of four-quadrant triacs from WeEn Semiconductors. The series includes various voltage ratings and package options, such as through-hole TO-220 variants like the BT137-600E. The BT137X-600F specifically adapts these electrical characteristics for surface-mount technology.

Triacs Replacement Considerations

Compatible substitutes include the BT137S-600F and BT137S-600,118 from WeEn Semiconductors, which share identical electrical ratings and the DPAK-3 package configuration.
