BT137B-600E,118

Triacs Overview

The BT137B-600E,118 is a sensitive gate four-quadrant triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 8 A and a repetitive peak off-state voltage 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 gate trigger voltage of 1.5 V, and a gate trigger current of 10 mA. It is housed in a DPAK-3 (TO-252-3) surface-mount package.

Triacs Feature Summary

• Sensitive gate architecture designed for direct interfacing with microcontrollers and low-power logic circuits.
• Four-quadrant triggering capability ensuring reliable operation across all gate polarities.

Triacs Applications

• General purpose bidirectional switching
• Phase control applications

Triacs Procurement Notes

Verify the specific suffix '118' against official manufacturer documentation to confirm the tape-and-reel packaging configuration. Ensure that the selected component matches the required surface-mount footprint and thermal management specifications for the target design.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required in a compact SMD form factor. Confirm compatibility with the driving circuit's ability to supply the specified 10 mA gate trigger current under varying temperature conditions.

Triacs Part Context

This part belongs to the BT137 series E triacs from WeEn Semiconductors. The series is characterized by planar passivation technology and sensitive gate structures intended for robust performance in AC power control environments.

Triacs Replacement Considerations

Cross-reference with other 8 A, 600 V sensitive gate triacs in TO-252 packages. Verify pinout compatibility and thermal characteristics before substituting with equivalent parts from other manufacturers.
