Overview
The ACTT8-800C0TQ is a bidirectional thyristor (triac) manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 8 A and a repetitive peak off-state voltage of 800 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220F-3 through-hole package. Key electrical characteristics include a maximum holding current of 35 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 30 mA. The on-state voltage is specified at 1.3 V, with a non-repetitive peak on-state current capability of 80 A.
Feature Summary
- Designed for general-purpose AC switching in static relays and heating regulation circuits
- Suitable for phase control operations in light dimmers and motor speed controllers
- Capable of interfacing with low-power drivers via logic-level triggering specifications
Applications
- Static relay ON/OFF functions
- Heating regulation systems
- Induction motor starting circuits
- Light dimmer phase control
- Motor speed controller applications
Procurement Notes
Verify the specific suffix 'Q' against official manufacturer documentation to confirm packaging details, as suffixes often denote tape-and-reel configurations rather than functional changes. Confirm RoHS compliance status and lead-free conversion dates directly from the datasheet or product change notifications provided by WeEn Semiconductors prior to ordering.
Selection Notes
Select this component when an 8 A RMS current rating and 800 V blocking voltage are required for AC load control. Ensure the TO-220F-3 package fits the thermal and mechanical constraints of the design. Verify that the gate trigger requirements align with the driving circuit's output capabilities, particularly regarding the 30 mA gate current specification.
Part Context
This triac belongs to the ACTT series from WeEn Semiconductors, which includes various current ratings such as 10 A variants like the ACTT10-800CTQ. These devices are part of the broader thyristor family intended for industrial and consumer AC power management, offering planar passivation for improved reliability under high dV/dt conditions.
Replacement Considerations
Cross-reference with other 8 A, 800 V triacs in TO-220 packages if availability is limited. Verify pinout compatibility and thermal resistance values before substituting with equivalent parts from other manufacturers.
