BTA312B-600C,118

Triacs Overview

The BTA312B-600C,118 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT404 (D2PAK) surface-mountable plastic package designed for circuits with high static and dynamic dV/dt and dI/dt. The device features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 12 A. Non-repetitive peak on-state current reaches 100 A. Gate trigger current maximums are 35 mA across quadrants Q1, Q2, and Q3. The component supports a maximum junction temperature of 125 °C and offers a dV/dt rating of 500 V/µs.

Triacs Feature Summary

• High commutation capability allows full RMS current commutation at maximum rated junction temperature without snubber assistance.
• Planar passivated construction provides robustness against high static and dynamic dV/dt and dI/dt conditions.
• Three-quadrant operation ensures reliable triggering and switching performance across multiple gate signal polarities.

Triacs Applications

• Industrial motor control systems requiring high dV/dt immunity
• Solid-state relay designs utilizing surface-mount packaging
• AC power switching applications with high transient voltage stress

Triacs Procurement Notes

Verify the complete ordering part number includes the suffix ,118 to confirm reel packing configuration. Confirm RoHS compliance and lead-free status through official chemical content documentation. Ensure the supplier source aligns with WeEn Semiconductors authorized distribution channels to guarantee component authenticity and traceability.

Triacs Selection Notes

Select this variant when a D2PAK surface-mount package is required for thermal management and PCB space constraints. Choose the Series C specification if the application demands a dV/dt rating of 500 V/µs and a maximum junction temperature of 125 °C. Verify that the 12 A RMS current rating meets the continuous load requirements of the target circuit design.

Triacs Part Context

This component belongs to the BTA312 series of high commutation triacs from WeEn Semiconductors. The Series C designation specifically denotes the electrical characteristics including the 500 V/µs dV/dt rating and 125 °C thermal limit. It shares the same core silicon structure as Series B but differs in specific switching parameters and package handling specifications within the industrial thyristor portfolio.

Triacs Replacement Considerations

Direct pin-compatible alternatives include the BTA312B-600CT for higher temperature operation up to 150 °C. The BTA312B-600B offers a higher dV/dt rating of 1000 V/µs. Cross-reference datasheets to ensure gate trigger current and holding current parameters match the existing drive circuit design before substitution.
