BTA316X-800C,127

Triacs Overview

The BTA316X-800C,127 is a planar passivated high commutation three-quadrant triac in a TO-220F plastic package. It features an RMS current of 16 A and a repetitive peak off-state voltage of 800 V. The device supports a non-repetitive surge current of 140 A with a maximum on-state voltage of 1.5 V. Gate triggering requirements are specified at 35 mA across quadrants Q1, Q2, and Q3, with a maximum holding current of 35 mA. It operates within a junction temperature range up to +125 °C and exhibits a critical rate of rise of off-state voltage of 500 V/µs.

Triacs Feature Summary

• High commutation capability allows full rated RMS current commutation at maximum junction temperature without snubber circuits.
• Three-quadrant operation provides reliable switching performance under varying load conditions.
• Planar passivated construction ensures robustness against high static and dynamic dv/dt and di/dt stresses.

Triacs Applications

• Industrial motor control systems requiring high dv/dt immunity
• General purpose AC power switching applications
• Lighting control circuits

Triacs Selection Notes

Select this component for applications demanding high commutation performance at elevated temperatures. The Series C designation indicates optimized gate sensitivity for standard drivers compared to sensitive gate variants. Ensure thermal management accommodates the 125 °C junction limit and verify that the 16 A RMS rating aligns with the continuous load requirements of the target circuit design.

Triacs Part Context

This part belongs to the BTA316 series of high-power triacs from WeEn Semiconductors. It shares the core electrical architecture with the BTA316-800C but utilizes the TO-220F "full pack" package for enhanced mechanical stability and thermal dissipation. The Series C variant is distinct from the Series E (sensitive gate) and Series CT (high temperature) versions within the same family.

Triacs Replacement Considerations

Direct replacements include the BTA316-800C in the TO-220 package or the BTA316X-800E if lower gate drive current is acceptable. Verify pinout compatibility and thermal resistance differences when substituting between TO-220AB and TO-220F packages.
