BTA212B-800E,118

Triacs Overview

The BTA212B-800E,118 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It operates in a D2PAK-3 (SOT-404-3) surface-mount package with an 800 V rated repetitive off-state voltage and a 12 A RMS on-state current. The device features a maximum non-repetitive surge current of 105 A and a gate trigger current of 10 mA across all quadrants. It maintains a low holding current of 25 mA and supports junction temperatures up to 125 °C. This component belongs to the 'Series E' sensitive gate family, designed for interfacing with low-power drivers.

Triacs Feature Summary

• Three-quadrant operation providing balanced commutation performance and gate sensitivity
• Sensitive gate architecture optimized for direct interface with microcontrollers and low-power drivers
• Planar passivated construction ensuring robust industrial reliability

Triacs Applications

• Industrial motor control systems requiring reliable switching
• Solid-state relay circuits utilizing low-power logic interfaces
• General-purpose AC power regulation applications

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. The part number indicates reel packing configuration. Confirm RoHS compliance status and lead-free conversion dates through authorized channels prior to procurement. Ensure design compatibility with the specified thermal and electrical limits.

Triacs Selection Notes

Select this component when a surface-mount solution is required for moderate current AC switching applications. The 800 V rating suits standard industrial line voltages. Consider the 10 mA gate drive requirement for driver circuit sizing. Evaluate thermal management needs given the 125 °C maximum junction temperature limit in the D2PAK package.

Triacs Part Context

This triac is part of the BTA212 series from WeEn Semiconductors. It serves as a volume production component within the 'Series E' lineup. The manufacturer notes it as a non-preferred choice for new designs, recommending the BTA312 series instead. It shares the same physical footprint and general electrical characteristics as other variants in the BTA212 family.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Designers should consult the manufacturer's recommendation to transition to the BTA312 series for new implementations.
