BTA204X-800C/L03Q

Triacs Overview

The BTA204X-800C/L03Q is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220F-3 full pack plastic package designed for through-hole mounting. The device features an 800 V rated repetitive off-state voltage and supports a 4 A RMS on-state current with a 27 A non-repetitive peak current. Key electrical parameters include a maximum gate trigger current of 35 mA across all quadrants, a 1000 V/us static dV/dt rating, and a maximum junction temperature of +125°C. This component is engineered for applications requiring high commutation performance without snubber assistance.

Triacs Feature Summary

• High commutation capability allows full rated RMS current switching at maximum junction temperature without external snubber circuits
• Planar passivated construction provides robust protection against environmental stress and electrical transients
• Three quadrant operation ensures reliable triggering and commutation across multiple gate signal polarities

Triacs Applications

• Industrial motor control systems requiring high dv/dt immunity
• Solid state relays operating under high dynamic load conditions
• Power regulation circuits interfacing with logic ICs where high commutation is critical

Triacs Procurement Notes

Verify the specific suffix L03Q against official manufacturer documentation to confirm packaging and tape-and-reel specifications. Ensure that the TO-220F-3 package variant matches your thermal management requirements. Cross-reference the 12NC code with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Triacs Selection Notes

Select this component when circuit designs demand high commutation performance at elevated temperatures without adding passive snubber components. The 800 V blocking voltage suits medium-voltage AC loads. Verify that the 35 mA gate drive capability aligns with the output strength of the controlling microcontroller or driver IC to ensure reliable turn-on across all operating quadrants.

Triacs Part Context

This part belongs to the BTA204X series of high commutation triacs from WeEn Semiconductors. The 'Series C' designation specifically indicates optimization for circuits experiencing high static and dynamic dv/dt and di/dt stresses. It shares the core die technology with other BTA204X variants but differs in packaging and specific commercial suffixes.

Triacs Replacement Considerations

Direct replacements within the same family include BTA204X-800C/127. Other compatible alternatives may include BTA204X-600C for lower voltage applications or BTA204-800E if standard TO-220AB packaging is acceptable instead of the insulated TO-220F.
