BTA204W-600E,135

Triacs Overview

The BTA204W-600E,135 is a planar passivated triac manufactured by WeEn Semiconductors. It operates in a SOT-223 surface-mount package with four terminals. The device supports an RMS on-state current of 1 A and withstands a rated repetitive peak off-state voltage of 600 V. It features a maximum on-state voltage of 1.2 V and a gate trigger current of up to 10 mA across quadrants Q1, Q2, and Q3. The component handles a non-repetitive peak on-state current of 10 A and maintains a maximum holding current of 20 mA. It functions within a junction temperature range up to +125 °C and exhibits a dV/dt rating of 30 V/µs.

Triacs Feature Summary

Triacs Selection Notes

Select this component when a surface-mount solution is required for low-current AC switching applications. The SOT-223 package suits space-constrained designs. Ensure the 1 A RMS current rating meets load requirements. Verify that the 600 V blocking voltage aligns with the system's peak line voltages. Confirm compatibility with the driving circuit's ability to supply the specified gate trigger currents.

Triacs Part Context

This part belongs to the BTA204W series of planar passivated triacs from WeEn Semiconductors. The series is engineered for industrial applications requiring robust commutation in surface-mount formats. The BTA204W-600E variant specifically targets 600 V systems. It shares architectural similarities with through-hole counterparts like the BTA204-600E but utilizes a different thermal and mechanical interface suitable for PCB mounting.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same package and electrical class include the BTA204W-600D, which offers similar specifications but with a lower dV/dt rating of 20 V/µs and stricter gate trigger limits. Cross-package alternatives such as the BTA204-600E provide higher current capacity but require through-hole mounting.
