ACTT4S-800C,118

Overview

The ACTT4S-800C,118 is a logic-sensitive gate triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 4 A and a rated repetitive peak off-state voltage of 800 V. The device is housed in a D2PAK (TO-252) surface-mount package. Key electrical parameters include a maximum non-repetitive peak on-state current of 39 A at 50 Hz, a maximum holding current of 20 mA, and a maximum gate trigger voltage of 1 V. The component supports a maximum junction temperature of 125°C and complies with RoHS3 standards.

Feature Summary

• Logic-sensitive gate design for simplified drive circuitry
• Surface-mount D2PAK package for automated assembly
• High thermal stability up to 125°C junction temperature

Applications

• AC power switching applications
• Lighting control systems
• General purpose AC load control

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact packaging and reel specifications. Confirm RoHS3 compliance status directly with the supplier or official datasheet prior to procurement. Ensure the D2PAK footprint matches the target PCB layout requirements.

Selection Notes

Select this component for applications requiring 4 A RMS current handling at 800 V blocking voltage in a surface-mount format. Verify that the gate trigger requirements align with the logic-sensitive characteristics. Ensure the operating environment remains within the specified 125°C junction temperature limit.

Part Context

This part belongs to the ACTT series of triacs from WeEn Semiconductors. The series includes variants with different current ratings and packages. The 'S' designation typically indicates a specific package type, while '800' denotes the voltage rating. This model is distinct from through-hole or higher-current variants in the same family.

Replacement Considerations

Direct replacements must match the 4 A RMS, 800 V rating and D2PAK package. Check equivalent parts from other manufacturers for compatible gate trigger characteristics and thermal performance. Verify pinout compatibility before substitution.
