ACTT16B-800CTNJ

Overview

The ACTT16B-800CTNJ is a high commutation triac manufactured by WeEn Semiconductors, housed in a TO263 (D2PAK) surface-mount package. It features an 800 V rated repetitive off-state voltage and supports a 16 A RMS on-state current. The device handles a non-repetitive peak surge current of 140 A and maintains a low on-state voltage of 1.22 V. Key electrical characteristics include a maximum holding current of 60 mA and a gate trigger current of 35 mA across all quadrants. It operates at a maximum junction temperature of 150 °C with a dV/dt rating of 1500 V/µs.

Feature Summary

• High commutation capability allows full RMS current commutation at maximum rated junction temperature without snubber circuits.
• Self-protective clamping capabilities against low and high energy transients enhance device reliability.
• Industrial qualification ensures suitability for demanding power switching applications.

Applications

• High junction operating temperature power switching circuits
• AC thyristor power control systems requiring high dV/dt immunity
• Industrial motor control and heating regulation

Procurement Notes

Verify the specific suffix 'J' indicates the reel packaging format as documented in official ordering lists. Confirm RoHS compliance and lead-free status through the manufacturer's chemical content documentation. Ensure the TO263 footprint matches the design layout before procurement.

Selection Notes

Select this component when high thermal stability up to 150 °C is required without external snubber networks. The 16 A current rating and 800 V blocking voltage suit medium-power AC loads. Verify that the 35 mA gate drive capability aligns with the control circuit output specifications.

Part Context

This part belongs to the ACTT series of planar passivated triacs designed for robust performance in high-stress environments. The 'CT' designation signifies high commutation characteristics, while the 'N' suffix typically denotes specific tape-and-reel packaging configurations within the product line.

Replacement Considerations

Direct substitutes include BTA416-800CT and ACTT16B-800CTN. Verify pinout compatibility and thermal resistance values when cross-referencing with these equivalent devices from the same manufacturer family.
