BTA310-800E,127

Triacs Overview

The BTA310-800E,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It operates in a TO-220AB (SOT78) plastic package with through-hole mounting. The device supports an RMS on-state current of 10 A and a non-repetitive peak on-state current of 85 A. It features a rated repetitive peak off-state voltage of 800 V and a maximum junction temperature of +125°C. Gate trigger current is specified at 10 mA across quadrants Q1, Q2, and Q3, while the static dv/dt rating is 50 V/µs.

Triacs Feature Summary

• Three-quadrant operation designed for high commutation performance
• Planar passivated structure for improved reliability
• Balanced gate sensitivity suitable for low power drivers

Triacs Applications

• Interfacing with microcontrollers
• Low power driver circuits
• Industrial control systems

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing method. The standard configuration utilizes a horizontal rail pack format. Confirm RoHS compliance status and lead-free conversion dates against the latest manufacturer documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when interfacing with low power drivers requiring balanced commutation performance and gate sensitivity. Ensure the application voltage does not exceed the 800 V rating and that thermal management supports the 125°C maximum junction temperature limit within the TO-220AB package constraints.

Triacs Part Context

This part belongs to the Series E triac family from WeEn Semiconductors. It is specifically engineered to balance commutation performance with gate sensitivity. The design targets applications requiring reliable switching in industrial environments where compatibility with low power logic interfaces is essential.

Triacs Replacement Considerations

Check for direct substitutes within the same series, such as the BTA310X-800E,127, which offers identical electrical characteristics but utilizes a TO-220F full pack package. Verify pinout compatibility and thermal resistance differences before substituting.
