• Planar passivated construction ensuring robust performance in phase control environments

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official documentation, as it may indicate a distinct electrical characteristic or packaging format compared to other variants like 'D'. Confirm RoHS compliance status through the latest datasheet revision. Ensure the component matches the required TO-220FP-3 footprint for PCB integration.

Triacs Selection Notes

Select this component when a high-sensitivity gate is required to interface directly with digital logic without additional buffer drivers. The 600 V rating suits standard AC line voltage applications. Verify that the 100 mA maximum gate trigger current aligns with the driving circuit's output capabilities to ensure reliable turn-on.

Triacs Part Context

This part belongs to the BT137X series of sensitive gate triacs from WeEn Semiconductors. The series is engineered for applications requiring low gate power consumption. The 'X' designation typically denotes the sensitive gate variant, distinguishing it from standard gate versions within the broader product family.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other sensitive gate triacs only if electrical parameters such as Igt, Vdrm, and package type are strictly matched.
