BT139-600E/DG,127

Triacs Overview

The WeEn Semiconductors BT139-600E/DG,127 is a planar passivated four-quadrant triac housed in a TO-220F (SOT186A) plastic package. It features a rated on-state RMS current of 16 A and a repetitive peak off-state voltage of 600 V. The device supports a non-repetitive surge current of 170 A and operates within a junction temperature range up to +125 °C. Key electrical parameters include a maximum gate trigger current of 22 mA and a holding current of 45 mA.

Triacs Feature Summary

• Planar passivated four-quadrant design for high bidirectional transient and blocking voltage capability
• TO-220F full pack plastic package optimized for high thermal cycling performance
• Suitable for applications requiring robust static switching and industrial control

Triacs Applications

• Motor control systems
• Industrial lighting regulation
• Domestic heating controls
• Static switching circuits

Triacs Procurement Notes

Verify the specific suffix DG against official manufacturer documentation to confirm pinout or marking variations. Ensure the component matches the SOT186A package profile. Cross-reference the part number with authorized distributors to confirm availability status and production lifecycle stage before finalizing procurement plans.

Triacs Selection Notes

Select this component when a 16 A RMS current rating and 600 V blocking voltage are required in a through-hole TO-220F package. Consider the 22 mA gate trigger current for driver compatibility. Evaluate thermal management requirements given the 125 °C maximum junction temperature limit and the specific thermal resistance characteristics of the rail pack housing.

Triacs Part Context

This part belongs to the BT139X series of high-power triacs from WeEn Semiconductors. It shares the core silicon structure with variants like the BT139X-600,127 but may differ in packaging configuration or specific manufacturing lot markings indicated by the DG suffix. It serves as a replacement for legacy NXP/Philips triacs in similar power handling classes.

Triacs Replacement Considerations

Direct substitutes include the BT139X-600,127. Verify pin compatibility and thermal performance equivalence before substitution. Other family members like the BT139-600E,127 offer different current ratings and should be evaluated based on specific circuit load requirements.
