Overview
The ACTT16-800CTNQ is a bidirectional thyristor (triac) manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 16 A and a rated repetitive peak off-state voltage of 800 V. The device operates with a maximum junction temperature of +150 °C and includes self-protective clamping capabilities against low and high energy transients. Packaged in a surface-mount TO-263 (D2PAK) format, it supports full RMS current commutation at maximum rated temperatures without requiring a snubber circuit.
Feature Summary
- Integrated self-protective clamping to handle transient energy events
- High thermal stability allowing operation up to 150 °C junction temperature
- Snubberless commutation capability at maximum rated operating conditions
Applications
- AC power control circuits requiring high junction temperature tolerance
- Industrial motor speed control systems
- Solid-state relays and contactors
Procurement Notes
Verify the specific suffix 'Q' against the official manufacturer datasheet to confirm packaging configuration and marking details. Ensure compatibility with standard SMT reflow profiles for the TO-263 package. Cross-reference the 12NC code for accurate ordering and traceability requirements.
Selection Notes
Select this component when a surface-mount triac with robust transient protection is required. The 16 A rating suits moderate power loads, while the 800 V blocking voltage provides adequate margin for standard industrial AC lines. Verify gate trigger characteristics match the driving circuit constraints.
Part Context
This part belongs to the ACTT series of planar passivated triacs from WeEn Semiconductors. It shares the core electrical architecture with the ACTT16B-800CTN but utilizes the 'Q' suffix to denote specific tape-and-reel packaging or regional compliance variations within the D2PAK form factor.
Replacement Considerations
The ACTT16B-800CTN is a verified equivalent in the same family with identical electrical ratings. For through-hole replacements, consider the BTA16-800BQ, noting the package change from surface-mount to leaded.
