BTA312B-800E,118

Triacs Overview

The BTA312B-800E,118 is a planar passivated high commutation three-quadrant triac housed in a TO263 (D2PAK) surface-mountable plastic package. This Series E device balances commutation performance with gate sensitivity for interfacing with low-power drivers. Key electrical parameters include a rated repetitive peak off-state voltage of 800 V and an on-state RMS current of 12 A. The maximum non-repetitive surge current is 100 A. Gate trigger current is limited to 10 mA across quadrants Q1, Q2, and Q3. The device supports a dV/dt rating of 500 V/µs and operates at a maximum junction temperature of 125 °C.

Triacs Feature Summary

• Planar passivated structure designed for high commutation performance in three-quadrant operation.
• Sensitive gate architecture optimized for direct interfacing with low-power logic drivers and microcontrollers.
• Surface-mountable TO263 package construction suitable for automated assembly processes.

Triacs Applications

• Industrial motor control systems requiring robust switching capabilities.
• Solid-state relay circuits utilizing sensitive gate drive interfaces.
• High-temperature industrial environments where reliable commutation is critical.

Triacs Procurement Notes

Verify the complete orderable part number includes the suffix ,118 to ensure correct reel packaging configuration. Confirm RoHS compliance status and lead-free plating specifications against current environmental regulations. Check the latest datasheet revision for any updates to thermal characteristics or qualification standards before finalizing procurement documentation.

Triacs Selection Notes

Select this component when a three-quadrant triac with high dV/dt immunity is required alongside sensitive gate drive compatibility. Ensure the application circuit can handle the specified 12 A RMS current within the thermal constraints of the TO263 package. Consider the 125 °C junction limit when designing heat dissipation strategies for continuous operation scenarios.
