ACTT4X-800C/DGQ

Overview

The ACTT4X-800C/DGQ is a triac manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 4 A and supports non-repetitive peak on-state currents up to 38.5 A. The device has a rated repetitive peak off-state voltage of 800 V and maintains a maximum on-state voltage of 1.6 V. Gate triggering specifications include a maximum gate trigger voltage of 800 mV and a maximum gate trigger current of 23 mA. The component operates within a junction temperature range of -40°C to +125°C and is housed in a TO-220F-3 through-hole package.

Feature Summary

• Logic-sensitive gate architecture enabling reliable triggering with low drive power requirements.
• High thermal stability supporting continuous operation at elevated junction temperatures up to 125°C.
• Robust construction providing high surge current capability for handling transient loads.

Applications

• Solid-state relays requiring compact AC load switching
• Motor speed control circuits for small appliances
• Lighting dimmer modules for residential or commercial use

Procurement Notes

Verify the specific suffix DGQ against official manufacturer documentation to confirm marking orientation and rail pack packaging details. Ensure compatibility with assembly processes regarding the TO-220F-3 lead form. Cross-reference part number aliases such as 934072167127 for accurate inventory matching during sourcing.

Selection Notes

Select this component when a 4 A RMS current rating and 800 V blocking voltage are required in a standard through-hole configuration. Evaluate the 23 mA maximum gate trigger current against the driving circuit capabilities to ensure sufficient sensitivity. Confirm that the TO-220F-3 thermal dissipation characteristics meet the system's heat management requirements under expected load conditions.

Part Context

This part belongs to the ACTT series of logic-sensitive triacs from WeEn Semiconductors. The series offers various current ratings and voltage classes packaged in both surface-mount and through-hole formats. The ACTT4X variant specifically targets mid-power AC control applications where moderate current handling and standard isolation are necessary.

Replacement Considerations

Consult official substitution guides for equivalent triacs with matching 4 A RMS, 800 V, and TO-220F-3 specifications. Verify pinout compatibility and thermal resistance values before implementing any cross-brand replacements.
