Overview
The ACTT8B-800C0TJ is a bidirectional thyristor (Triac) manufactured by WeEn Semiconductors. It features an RMS on-state current of 8 A and a rated repetitive peak off-state voltage of 800 V. The device has a non-repetitive peak on-state current of 80 A, an on-state voltage of 1.3 V, and a maximum holding current of 35 mA. Gate trigger voltage is 800 mV with a gate trigger current of 30 mA. It operates within a temperature range of -40°C to +125°C and utilizes a surface-mount D2PAK package.
Feature Summary
- Planar passivated construction for enhanced voltage ruggedness and reliability
- Capable of triggering in all four quadrants for versatile control applications
- High noise immunity suitable for demanding industrial environments
Applications
- Motor drive and control systems
- Industrial automation and process control
- Lighting dimmer circuits
- HVAC solid-state switching
Procurement Notes
Verify the specific suffix 'TJ' against official manufacturer documentation to confirm tape-and-reel packaging specifications and marking details. Ensure compatibility with standard SMT assembly processes for the D2PAK form factor. Cross-reference part numbers with authorized distributors to confirm current availability status and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when an 8 A RMS current rating and 800 V blocking voltage are required in a compact surface-mount footprint. Compare gate sensitivity requirements, specifically the 30 mA trigger current, against available driver capabilities. Evaluate thermal management needs for the D2PAK package under expected load conditions and ambient temperatures up to 125°C.
Part Context
This Triac belongs to the ACTT series from WeEn Semiconductors, designed for general-purpose AC power switching. The series offers various current ratings and packages, with the ACTT8 variant balancing moderate current handling with robust voltage blocking in a space-efficient SMD housing.
Replacement Considerations
Direct substitutes include other 8 A, 800 V Triacs in D2PAK packages such as the BTA16 or equivalent logic-level gate variants. Verify pinout compatibility and thermal resistance values before substitution.
