BTA310X-800D,127

Triacs Overview

The BTA310X-800D,127 is a planar passivated high commutation three-quadrant triac housed in a SOT186A (TO-220F) full pack plastic package. Designed for interfacing with low-power drivers including microcontrollers, this Series D device balances commutation performance and gate sensitivity. Key electrical parameters include a repetitive peak off-state voltage of 800 V, an on-state RMS current of 10 A, and a non-repetitive peak on-state current of 85 A. The maximum gate trigger current is 5 mA across all quadrants, with a critical rate of rise of off-state voltage of 20 V/µs. The component supports industrial qualification and operates up to a maximum junction temperature of 125 °C.

Triacs Feature Summary

• Planar passivated structure designed for high commutation performance
• Three-quadrant operation capability for versatile AC control
• Optimized gate sensitivity for direct interface with low-power logic drivers

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the complete orderable part number includes the suffix ,127 to ensure correct packaging configuration. Confirm RoHS compliance and lead-free status against the latest chemical content documentation provided by WeEn Semiconductors. Cross-reference the 12NC code 9340 661 77127 during procurement to match specific manufacturing batches and quality standards.

Triacs Selection Notes

Select this component when a TO-220F package is required for thermal management alongside 800 V blocking capability. Ensure the application circuit can handle the 20 V/µs dV/dt rating without additional snubber networks. Verify that the driving circuit provides sufficient gate current to trigger the device within the specified 5 mA limit across all operating quadrants.

Triacs Part Context

This device belongs to the BTA310X series of high commutation triacs from WeEn Semiconductors. It shares the same core electrical characteristics as the BTA310X-800C and BTA310X-800E variants but differs in gate sensitivity and dV/dt ratings. The Series D designation specifically targets applications requiring a balance between robust commutation and compatibility with sensitive microcontroller outputs.

Triacs Replacement Considerations

Direct functional substitutes within the same package and voltage class include the BTA310X-800C and BTA310X-800E. Note that these alternatives exhibit different gate trigger currents and dV/dt ratings, necessitating a review of the gate drive circuit and snubber requirements before substitution.
