BTA420X-800CT/L02Q

Triacs Overview

The BTA420X-800CT/L02Q is a 3Q Hi-Com Triac manufactured by WeEn Semiconductors, designed for high-performance AC power control applications. It features an RMS on-state current (It rms) of 20 A and a non-repetitive peak on-state current of 220 A. The device supports a rated repetitive peak off-state voltage (Vdrm) of 800 V with a maximum off-state leakage current of 200 uA at Vdrm. Key electrical parameters include an on-state voltage of 1.2 V, a holding current (Ih) maximum of 40 mA, a gate trigger voltage (Vgt) of 700 mV, and a gate trigger current (Igt) of 35 mA. It operates within a temperature range up to +150 C and utilizes a TO-220F through-hole package.

Triacs Feature Summary

• High commutation capability enabled by 3Q Hi-Com technology
• Sensitive gate design for reliable triggering with low gate current
• Robust thermal performance supporting operation up to +150 C

Triacs Applications

• Industrial motor speed control systems
• High-power heating element regulation
• Lighting dimmer circuits requiring high surge tolerance

Triacs Procurement Notes

Verify the specific suffix /L02Q against official WeEn Semiconductors documentation to confirm packaging details, as standard variants may differ in reel or tube configuration. Confirm RoHS compliance status and REACH SVHC declarations directly from the latest datasheet before integration. Ensure the procurement channel provides valid traceability for this discontinued or limited-stock component type.

Triacs Selection Notes

Select this component when a 20 A RMS triac with 800 V blocking voltage is required for high-surge industrial loads. The sensitive gate characteristic (35 mA Igt) allows for efficient drive from standard logic interfaces. Consider the TO-220F package for adequate heat dissipation without external heatsinks in moderate duty cycles. Validate that the 1.2 V on-state voltage meets system efficiency targets compared to higher-voltage alternatives.

Triacs Part Context

This part belongs to the BTA420X series of 3Q Hi-Com Triacs from WeEn Semiconductors. The series is characterized by high dv/dt immunity and robustness against false triggering. The L02Q suffix typically denotes specific marking or packaging variations within the TO-220F form factor, distinguishing it from standard tube-packaged versions like the BTA420X-800CT/127.

Triacs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing circuit designs if considering alternative manufacturers' 20 A, 800 V Hi-Com Triacs.
