BTA316X-800E,127

Triacs Overview

The BTA316X-800E,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220F (SOT186A) plastic package and designed for industrial applications. The device features an 800 V rated repetitive off-state voltage and conducts a continuous RMS on-state current of 16 A. It supports a non-repetitive peak on-state current of 140 A with a maximum junction temperature of 125 °C. Key electrical characteristics include a gate trigger current of 10 mA across all quadrants and a static dv/dt rating of 60 V/µs.

Triacs Feature Summary

• High commutation capability suitable for circuits with high static and dynamic dv/dt and di/dt stresses
• Sensitive gate design optimized for direct interfacing with low power drivers such as microcontrollers
• Planar passivation technology provides robust protection against mechanical stress and environmental factors

Triacs Applications

• Industrial motor control systems requiring high noise immunity
• Solid state relays operating under high dv/dt conditions
• General purpose AC power switching applications

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing method. The standard designation indicates a TO-220F full pack configuration. Confirm RoHS compliance status and lead-free plating requirements prior to integration. Ensure the selected variant matches the required thermal management specifications for the target application environment.

Triacs Selection Notes

Select this component when high commutation performance is critical alongside sensitive gate drive requirements. The TO-220F package offers a balance between thermal dissipation and mounting flexibility compared to smaller surface mount options. Verify that the 125 °C maximum junction temperature aligns with the system's thermal design constraints and ambient operating conditions.

Triacs Part Context

This part belongs to the BTA316 series of three quadrant triacs from WeEn Semiconductors. The 'X' suffix specifically denotes the SOT186A (TO-220F) full pack plastic housing. This distinguishes it from other series variants like the BTA316E or BTA316ET which utilize different package styles or higher temperature ratings within the same electrical family.

Triacs Replacement Considerations

Direct replacements must match the 800 V voltage rating, 16 A current capacity, and TO-220F footprint. Verify that substitute components maintain equivalent three quadrant operation and sensitive gate sensitivity to ensure compatibility with existing driver circuitry without modification.
