Overview
The ACTT8X-800C0TQ is a bidirectional thyristor manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current (It RMS) of 8 A and supports a non-repetitive peak on-state current of 80 A. The device has a rated repetitive off-state voltage (VDRM) of 800 V. Key electrical parameters include an on-state voltage of 1.3 V, a maximum holding current (Ih) of 35 mA, a gate trigger voltage (Vgt) of 800 mV, and a gate trigger current (Igt) of 30 mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- High thermal stability with a maximum operating junction temperature of 125°C
- Sensitive gate triggering capability for efficient control circuit interfacing
- Robust surge current handling with 80 A non-repetitive peak rating
Applications
- AC motor speed control systems
- Solid-state relay modules
- Lighting dimmer circuits
Procurement Notes
Verify the specific suffix 'TQ' against official manufacturer documentation to confirm tape-and-reel packaging details and marking variations. Ensure compatibility with standard TO-220F mounting requirements during integration. Cross-reference datasheet revisions to confirm compliance with current environmental directives before finalizing procurement specifications.
Selection Notes
Select this component when an 8 A RMS current rating at 800 V blocking voltage is required in a through-hole package. Compare gate trigger sensitivity against alternative triacs if low-power drive signals are used. Verify that the 1.3 V on-state voltage meets thermal dissipation constraints for the intended load profile.
Part Context
This part belongs to the ACTT8X series of high-performance triacs from WeEn Semiconductors. The series is engineered for general-purpose AC power control, offering reliable switching in compact packages. It complements other variants in the family that may differ in current ratings or packaging styles.
Replacement Considerations
Check for direct pin-compatible substitutes within the same voltage and current class. Verify that any replacement maintains identical gate trigger characteristics and thermal resistance values to ensure circuit stability without redesign.
