T1610T-8G

Overview

The T1610T-8G is a logic level T-series Triac in a D²PAK surface-mount package. It features an RMS on-state current of 16 A and a repetitive peak off-state voltage of 800 V. The device supports a non-repetitive peak off-state voltage of 900 V and has a maximum junction temperature of 150 °C. Gate trigger current is limited to 10 mA, enabling direct microcontroller control. Electrical characteristics include a holding current of 25 mA maximum and a threshold on-state voltage of 0.85 V at 150 °C.

Feature Summary

• Logic level operation allows direct driving by microcontrollers with simplified circuitry
• Optimized for high electromagnetic interference constraints within the T-series family
• D²PAK package utilizes halogen-free molding compound compliant with UL94 V0 flammability standards

Applications

• General purpose AC line load switching
• Small home appliances with resistive loads
• Hybrid relays
• Inrush current limiting circuits
• Overvoltage crowbar protection

Procurement Notes

Verify the specific ordering suffix when purchasing components. The standard tube packaging corresponds to the base part number without additional letters, while tape and reel options utilize a TR suffix. Confirm that the received units match the required packing format for automated manufacturing processes or manual assembly workflows.

Selection Notes

Select this component for applications requiring compact SMT designs with automated manufacturing capabilities. The extended thermal margin up to 150 °C provides increased operational flexibility compared to standard 125 °C devices. Ensure the gate drive circuit can supply the specified 10 mA trigger current for reliable activation across all three quadrants.

Part Context

This device belongs to STMicroelectronics' T-series Triac lineup, which is engineered for high EMI performance. The T1610T-8G specifically targets general-purpose AC switching applications where space-saving surface mount technology is preferred over through-hole alternatives like the TO-220AB insulated variants found in other series members.

Replacement Considerations

Direct functional replacements within the same package and rating profile include the T1610T-8I (TO-220AB Insulated) and T1610T-8T (TO-220AB). For PCB layout compatibility, no other D²PAK triacs share identical pinout and thermal specifications without mechanical modification.
