Overview
The ACTT12-800CQ is a bidirectional thyristor (Triac) manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 12 A and a non-repetitive peak on-state current of 13.7 A. The device supports a rated repetitive peak off-state voltage of 800 V with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include an on-state voltage of 1.6 V, a maximum holding current of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 20 mA. It operates within a temperature range from -40°C to +125°C and utilizes a TO-220AB-3 through-hole package.
Feature Summary
- High current handling capability suitable for demanding AC load control
- Robust thermal performance with a maximum junction temperature of 125°C
- Sensitive gate triggering characteristics for efficient drive circuit integration
Applications
- AC motor speed control systems
- Solid-state relay implementations
- Industrial heating element regulation
Procurement Notes
Verify the specific suffix 'CQ' against official WeSem datasheets to confirm exact packaging configuration and marking details. Ensure compatibility with existing thermal management designs given the 12 A RMS rating. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when an 800 V blocking voltage and 12 A continuous current are required in a through-hole format. Compare the 1.6 V on-state voltage against alternatives to assess conduction losses. Verify that the 20 mA gate trigger current aligns with the available drive signal strength in the target application circuit.
Part Context
This Triac belongs to the ACTT series from WeEn Semiconductors, which focuses on high-power AC switching solutions. The series typically offers various current ratings and voltage classes packaged in standard through-hole and surface-mount formats. The ACTT12 variant specifically targets mid-to-high power industrial applications requiring reliable AC phase control.
Replacement Considerations
Consult official substitution guides for equivalent 12 A, 800 V Triacs in TO-220 packages. Verify pinout compatibility and thermal resistance values before replacing with parts from other manufacturers such as STMicroelectronics or Littelfuse.
