Selection Notes

Select this component for applications requiring a 4 A RMS current rating in a compact through-hole package. Ensure the gate drive circuit can supply at least 30 mA to guarantee reliable triggering at the specified 700 mV threshold. Consider the 600 V blocking voltage for appropriate line voltage compatibility.

Part Context

This part belongs to the BT134 series of rail triacs from WeEn Semiconductors. The series offers various current ratings and voltage options within standardized packages like SOT-82-3 and TO-220FP. The BT134-600 variant specifically targets general-purpose AC power control needs with balanced electrical characteristics.

Replacement Considerations

Check datasheets for equivalent parts such as BT134-600R or BT136X-600D if pinout and package compatibility are required. Verify that replacement devices meet the same 4 A RMS and 600 V specifications.
