T610T-8FP

Overview

The T610T-8FP is a logic-level TRIAC from the STMicroelectronics ACS™/A.S.D® series, rated for 800 V repetitive peak off-state voltage and 6 A RMS on-state current. It features a maximum gate trigger current of 10 mA, enabling direct microcontroller drive. The device operates within a junction temperature range of -40°C to 125°C and is housed in an insulated TO-220FPAB fullpack package providing 2000 VRMS isolation. Non-repetitive surge currents are rated at 47 A for 60 Hz operation.

Feature Summary

• Logic-level sensitivity allows direct interfacing with standard digital logic or microcontrollers without additional buffer circuits.
• Insulated TO-220FPAB package provides high dielectric strength for safety isolation between control and power sides.
• High performance characteristics include elevated thermal capability and robust dI/dt and dV/dt ratings.

Applications

• On/off switching and phase angle control in general-purpose AC power applications
• Residential appliance motor control such as washing machines and air conditioners
• Heating element regulation in ovens and water heaters

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment for the TO-220FPAB form factor. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 6 A RMS current rating and 800 V blocking voltage are required for AC load control. The logic gate sensitivity simplifies driver design compared to standard TRIACs. Consider the insulated package for applications requiring galvanic isolation without external optocouplers. Verify that the thermal management solution supports the specified junction temperature limits under expected load conditions.

Part Context

This device belongs to the T610T family of medium-current TRIACs designed for AC switching. It shares functional similarities with the T610T-8T but utilizes a through-hole package instead of surface mount. The product line emphasizes compatibility with modern digital control interfaces while maintaining robust power handling capabilities for household and industrial AC loads.

Replacement Considerations

The T610T-8T serves as a surface-mount alternative within the same electrical family. Other compatible options include the T1210T-8FP for higher current requirements or the ACST610-8FP for similar performance in a comparable package. Verify pinout compatibility and thermal resistance differences before substitution.
