ACTT12B-800CTJ

Overview

The ACTT12B-800CTJ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO263 surface-mountable plastic package and features self-protective clamping capabilities against low and high energy transients. The device supports full RMS current commutation at a maximum junction temperature of 150°C without requiring a snubber circuit. Key electrical parameters include an 800V rated repetitive off-state voltage, a 12A on-state RMS current, and a non-repetitive peak on-state current of 120A. Maximum gate trigger currents are specified at 35mA across all quadrants.

Feature Summary

• High junction operating temperature capability up to 150°C
• Self-protective clamping against transient energy
• Snubberless operation at maximum rated temperature

Applications

• Circuits with high static and dynamic dV/dt
• Applications requiring high dI/dt handling
• Industrial power switching systems

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's official documentation to confirm packing details and RoHS compliance status. Ensure the orderable part number matches the required reel specifications for automated assembly processes.

Selection Notes

Select this component when applications demand high thermal stability and robust transient protection in a surface-mount format. The absence of snubber requirements simplifies design complexity while maintaining performance under high di/dt conditions.

Part Context

This part belongs to the WeEn Semiconductors ACTT series of AC thyristor triacs. It utilizes a planar passivated structure designed for industrial environments where reliability under extreme electrical stress is critical.

Replacement Considerations

Direct substitutes include the BTA312B-800CTJ, which shares identical electrical ratings and the TO263 package form factor.
