T810T-8FP

Overview

The STMicroelectronics T810T-8FP is a logic-level Triac designed for general-purpose AC switching applications. It operates with an RMS on-state current of 8 A and supports a repetitive peak off-state voltage of 600 V. The device features a low gate trigger current of 10 mA, enabling direct control by microcontrollers. It utilizes the ECOPACK2 package, which is halogen-free and RoHS compliant. The component is rated for a maximum junction temperature of 150 °C and offers three-quadrant triggering capability.

Feature Summary

• Logic-level gate sensitivity allows direct interfacing with standard microcontroller outputs without additional driver circuitry.
• ECOPACK2 surface-mount packaging ensures environmental compliance through halogen-free and RoHS-compliant materials.
• Three-quadrant operation provides reliable switching performance across various gate signal polarities.

Applications

• General purpose AC switching with resistive loads
• Phase angle control circuits
• On/off control functions in industrial equipment

Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm pinout and electrical ratings. Ensure the procurement channel sources genuine components from authorized distributors to maintain quality standards. Check for recent product change notifications regarding manufacturing updates or obsolescence status before finalizing orders.

Selection Notes

Select this component when a compact surface-mount solution is required for 8 A AC load control. The logic-level gate characteristic simplifies drive circuit design compared to standard gate devices. Consider the 600 V blocking voltage rating relative to the line voltage requirements of the target application.

Part Context

This Triac belongs to the T-series family optimized for high EMI constraints and simplified MCU integration. It complements other medium-current thyristors in the ST portfolio, offering a balance between current handling capacity and physical footprint for automated PCB assembly processes.

Replacement Considerations

Direct substitutes include the T810T-8G (D2PAK) for similar electrical characteristics in a different package. For through-hole equivalents, consider the T810T-8T. Verify compatibility with existing board layouts and thermal management strategies when transitioning between package types.
