ACTT8B-800CTNJ

Overview

The ACTT8B-800CTNJ 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 non-repetitive peak on-state current of 80 A. The device supports a rated repetitive peak off-state voltage of 800 V with an on-state voltage of 1.3 V. Key gate parameters include a maximum holding current of 35 mA, a gate trigger voltage of 800 mV, and a gate trigger current of 30 mA. It operates within a temperature range of -40 °C to +125 °C and is housed in a TO-263 (D2PAK) surface-mount package.

Feature Summary

• Surface-mountable plastic package design suitable for automated assembly processes
• Self-protective clamping capabilities against low and high energy transients
• High junction operating temperature capability up to 150 °C for snubberless commutation

Applications

• AC power switches requiring high junction operating temperature capability
• Applications demanding self-protective clamping against transient voltages
• Snubberless circuit designs utilizing full RMS current commutation at maximum temperatures

Procurement Notes

Verify the specific ordering suffix CTNJ against the manufacturer's official documentation to confirm package type and packing configuration. Ensure compatibility with standard SMD reflow profiles for the D2PAK form factor. Cross-reference the 12NC code 9340 692 29118 for accurate supply chain tracking and compliance verification.

Selection Notes

Select this component when a surface-mount Triac with 800 V blocking voltage and 8 A RMS current is required. The CTN series variant is appropriate for designs needing enhanced thermal performance up to 150 °C junction temperature. Verify that the D2PAK footprint matches the PCB layout constraints and that the gate drive circuitry can supply the specified trigger requirements.
