ACTT10-800CTQ

Overview

The ACTT10-800CTQ 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 supports a non-repetitive peak on-state current of 99 A. The device withstands a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include an on-state voltage of 1.3 V, a maximum holding current of 55 mA, a gate trigger voltage of 1 V, and a gate trigger current of 35 mA. It operates within a temperature range up to +125 C and is housed in a TO-220AB-3 through-hole package.

Feature Summary

• High thermal stability with a maximum operating temperature of +125 C
• Robust surge handling capability with 99 A non-repetitive peak current
• Low gate sensitivity requiring 35 mA trigger current for reliable activation

Applications

• AC power control circuits
• Solid-state relay implementations
• Motor speed control systems

Procurement Notes

Verify the specific ordering suffix CTQ against the manufacturer's official datasheet to confirm packaging details and marking conventions. Ensure that the procurement channel provides valid traceability documentation. Confirm compliance with RoHS and REACH standards as specified in the component's environmental declarations before finalizing purchase orders.

Selection Notes

Select this component when a 10 A RMS current rating and 800 V blocking voltage are required for through-hole assembly. The TO-220AB-3 package facilitates effective heat dissipation for moderate power levels. Evaluate the 1.3 V on-state voltage drop against system efficiency requirements and ensure the driving circuit can supply the necessary 35 mA gate trigger current for consistent switching performance.

Part Context

This Triac belongs to the ACTT series from WeEn Semiconductors, which focuses on general-purpose AC power switching solutions. The part utilizes standard silicon thyristor technology optimized for industrial and consumer electronics. It serves as a discrete alternative to integrated power modules, offering flexibility in custom PCB layout design while maintaining compatibility with standard mounting hardware.

Replacement Considerations

Cross-reference with other 10 A, 800 V Triacs in TO-220 packages such as BTA16 or BTB16 variants if pinout compatibility allows. Verify that substitute devices meet or exceed the 10 A RMS and 99 A surge current specifications. Check gate trigger characteristics to ensure driver circuit compatibility without modification.
