ACTT12-800CTNQ

Overview

The ACTT12-800CTNQ is a snubberless triac manufactured by WeEn Semiconductors, designed for AC power switching applications. It features an RMS on-state current of 12 A and a rated repetitive peak off-state voltage of 800 V. The device supports a non-repetitive peak on-state current of 95 A and maintains 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 component operates within a junction temperature range up to +150 °C and is housed in a TO-220AB-3 through-hole package.

Feature Summary

• Snubberless operation enabling full RMS current commutation at maximum rated junction temperature without external snubber circuits
• Self-protective clamping structure providing safe high over-voltage withstand capability against low and high energy transients
• High junction operating temperature capability allowing reliable performance at elevated thermal conditions

Applications

• AC power switches requiring high thermal stability
• Industrial motor control systems
• Solid-state relays
• Lighting dimmers

Procurement Notes

Verify the specific suffix 'Q' against official manufacturer documentation to confirm packaging or qualification variations. Ensure compatibility with existing thermal management designs due to the 150 °C junction rating. Cross-reference datasheet parameters for gate sensitivity and holding current before integration into final assemblies.

Selection Notes

Select this component when snubberless functionality is required to simplify circuit design and reduce component count. The 12 A RMS rating suits moderate power loads, while the 800 V blocking voltage provides adequate margin for standard industrial AC lines. Consider the TO-220AB package for through-hole mounting and robust heat dissipation needs.

Part Context

This part belongs to the ACTT series of triacs from WeEn Semiconductors, which are engineered for robust AC power control. The CTN designation typically indicates specific internal clamping and snubberless characteristics. These devices are commonly used in applications demanding high reliability and simplified peripheral circuitry compared to traditional triacs requiring external RC networks.

Replacement Considerations

Check for direct substitutes such as the ACTT12-800CTN or TOPT12-800C0, ensuring pinout and electrical ratings match. Verify that alternative components support the same 150 °C junction temperature and snubberless operation requirements.
