ACTT10-800CTNQ

Overview

The ACTT10-800CTNQ is a bidirectional thyristor (triac) manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 10 A and a non-repetitive peak on-state current of 99 A. The device supports a rated repetitive off-state voltage of 800 V with a maximum on-state voltage of 1.3 V. Gate triggering requirements include a maximum gate trigger voltage of 1 V and a maximum gate trigger current of 35 mA. The holding current is specified at a maximum of 55 mA. It operates within a temperature range of -40°C to +125°C and is housed in a TO-220AB-3 through-hole package.

Feature Summary

• High current handling capability with 10 A RMS rating for robust AC load control
• Low on-state voltage drop of 1.3 V to minimize conduction losses
• Sensitive gate configuration allowing direct interface with logic-level drivers
• Thermal resilience supporting operation up to 125°C junction temperature

Applications

• AC motor speed control circuits
• Solid-state relay implementations
• Lighting dimmer switches
• Heating element regulation systems

Procurement Notes

Verify the specific suffix 'Q' against official manufacturer documentation to confirm any distinct marking or compliance variations compared to standard variants. Ensure the ordering quantity aligns with factory packaging constraints, typically multiples of 1000 units. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards and RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when an 800 V blocking voltage and 10 A continuous current capacity are required in a through-hole format. The low gate trigger current facilitates drive from microcontrollers or optocouplers without additional amplification. Consider thermal management solutions given the TO-220AB-3 package's power dissipation characteristics under high-load conditions. Validate that the 1.3 V on-state voltage meets efficiency targets for the specific application load profile.

Part Context

This part belongs to the ACTT series of triacs from WeEn Semiconductors, which focuses on general-purpose AC power switching. The series offers various current ratings and voltage classes packaged in both surface-mount and through-hole configurations. The ACTT10 variant specifically addresses mid-power applications requiring reliable switching performance in compact industrial and consumer electronics designs.

Replacement Considerations

Potential substitutes include other 800 V, 10 A triacs in TO-220 packages such as the BTA16 series or equivalent parts from STMicroelectronics. Verify pinout compatibility and ensure that gate sensitivity and holding current parameters match the existing circuit design constraints before substitution.
