BT138-600G0TQ

Triacs Overview

The BT138-600G0TQ is a four-quadrant sensitive gate triac manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 12 A. The device has a non-repetitive peak on-state current of 105 A, a maximum on-state voltage of 1.4 V, and a holding current of 30 mA. Gate triggering parameters include a maximum gate trigger voltage of 700 mV and a maximum gate trigger current of 11 mA. It operates within a junction temperature range of -40 °C to +125 °C and is housed in a TO-220AB-3 package.

Triacs Feature Summary

• Four-quadrant sensitivity for reliable triggering across all gate polarities
• Sensitive gate design enabling direct interfacing with logic level ICs
• Passivated chip construction for enhanced robustness

Triacs Applications

• General purpose switching applications
• Phase control circuits
• Lamp dimmers

Triacs Procurement Notes

Verify the exact suffix 'G0TQ' against official WeEn Semiconductors documentation, as standard listings typically use suffixes like 'E,127'. Confirm RoHS compliance status and specific packaging details directly with the manufacturer or authorized distributors to ensure alignment with project requirements.

Triacs Selection Notes

Select this component for AC power control applications requiring 12 A continuous current handling at 600 V blocking voltage. Ensure the driving circuit can supply sufficient gate current (up to 11 mA) for reliable turn-on. Verify thermal management capabilities are adequate for the expected load conditions given the TO-220AB-3 package.

Triacs Part Context

This part belongs to the BT138 series of four-quadrant sensitive gate triacs from WeEn Semiconductors. The series is designed for general-purpose AC switching and phase control. Variants within the series differ primarily in voltage ratings (e.g., 600 V vs. 800 V) and specific gate sensitivity characteristics.

Triacs Replacement Considerations

Direct replacements may include other 12 A, 600 V four-quadrant triacs such as the BT138-600E,127 or equivalent parts from other manufacturers offering similar IT(RMS), VDRM, and package specifications.
