BT139-600-0Q

Triacs Overview

The BT139-600-0Q is a four-quadrant planar passivated triac manufactured by WeEn Semiconductors. It is housed in a TO-220AB plastic package designed for through-hole mounting. The device supports a repetitive peak off-state voltage of 600V and an RMS on-state current of 16A. It features a non-repetitive surge current rating of 170A, with a maximum holding current of 45mA. The gate trigger voltage is specified at 700mV, while the gate trigger current reaches 25mA. Operating temperatures range from -40°C to +125°C.

Triacs Feature Summary

• Four-quadrant triggering capability ensures reliable operation across all gate polarities.
• Planar passivation technology provides enhanced stability and protection against environmental factors.
• TO-220AB package design facilitates efficient heat dissipation for high-current applications.

Triacs Applications

• Industrial motor speed control systems

• High-power lighting dimmer controls

Triacs Procurement Notes

Verify the specific suffix '0Q' against official manufacturer documentation to confirm pinout and electrical tolerances. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards. Confirm that the supplier offers traceability for the semiconductor batch.

Triacs Selection Notes

Select this component when a robust 16A triac is required for AC power control. The 600V voltage rating suits standard industrial line voltages. Consider the thermal resistance of the TO-220AB package for heatsink requirements. Compare gate sensitivity against driving circuit capabilities to ensure reliable turn-on under varying temperature conditions.

Triacs Part Context

This part belongs to the BT139 family of high-current triacs from WeEn Semiconductors. The series is engineered for demanding power electronics applications. The BT139-600 variant specifically targets 600V blocking requirements. It complements other devices in the lineup offering different voltage or current ratings.

Triacs Replacement Considerations

Check equivalent models from other manufacturers such as STMicroelectronics or Nexperia. Verify that substitute parts match the 16A current and 600V voltage specifications. Ensure the replacement maintains the same TO-220AB footprint for mechanical compatibility.
