T1610T-8G-TR

Overview

The T1610T-8G-TR is a logic-level triac in the STMicroelectronics T-series, packaged in a surface-mount D²PAK (TO-263) housing. It supports an RMS on-state current of 16 A and offers repetitive peak off-state voltages of 800 V at 125 °C and 600 V at 150 °C. The device features a maximum gate trigger current of 10 mA, enabling direct microcontroller interfacing. Non-repetitive surge peak on-state currents reach 126 A for a full cycle at 25 °C initial junction temperature. Operating junction temperatures range from -40 °C to +150 °C.

• Small home appliances with resistive loads
• Hybrid relays
• Inrush current limiting circuits
• Overvoltage crowbar protection

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The TR suffix indicates tape and reel packaging, while the absence of a suffix denotes tube packaging. Confirm that the required quantity aligns with the base delivery mode specified in the manufacturer's ordering information table to ensure correct fulfillment.

Selection Notes

Select this component when designing compact SMT layouts requiring automated manufacturing processes. The extended thermal margin up to 150 °C provides increased operational flexibility compared to lower-rated devices. Ensure the application voltage does not exceed the 800 V rating under standard operating conditions to maintain reliable blocking performance.

Part Context

This part belongs to the STMicroelectronics T-series of triacs, which are engineered for high EMI constraints. The T1610T-8G variant specifically targets medium-current applications where low gate drive requirements simplify the interface with digital control logic. The D²PAK form factor facilitates efficient heat dissipation through the exposed tab.

Replacement Considerations

Direct replacements include other T-series triacs such as the T1610T-8I or T1610T-8T, provided the package type matches the design constraints. Verify that alternative components meet the same 16 A RMS current and 800 V voltage ratings to ensure functional equivalence in existing circuits.
