T1610T-8T

Overview

The T1610T-8T is a logic level Triac in a TO-220AB through-hole package, rated for 16 A RMS on-state current and 800 V repetitive off-state voltage. It features a maximum gate trigger current of 10 mA, enabling direct microcontroller drive. The device supports three-quadrant triggering with a maximum junction temperature of 150 °C. Key electrical parameters include a non-repetitive surge peak on-state current of 120 A at 50 Hz, a critical rate of rise of on-state current of 100 A/µs, and a static dV/dt immunity of 250 V/µs at 125 °C.

Feature Summary

• Logic-level sensitivity allows direct interfacing with microcontrollers via low gate current requirements.
• Three-quadrant triggering capability ensures reliable operation across various gate signal polarities.
• High thermal performance supports extended junction temperatures up to 150 °C.

Applications

• General purpose AC line load switching
• Motor control circuits
• Small home appliances
• Lighting systems
• Inrush current limiting circuits

Procurement Notes

Verify the specific ordering code T1610T-8T against the manufacturer's latest datasheet revision DS10472 Rev 3. Confirm that the TO-220AB package variant matches the required mechanical footprint and lead configuration for the target PCB layout. Ensure compliance with ECOPACK2 environmental standards if halogen-free materials are mandated for the assembly process.

Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current capacity are required in a standard through-hole form factor. The 10 mA gate trigger threshold makes it suitable for low-power digital logic interfaces without additional driver stages. Evaluate thermal management needs based on the 60 °C/W junction-to-ambient resistance for free-air convection scenarios.

Part Context

This part belongs to the STMicroelectronics T-Series Triacs, optimized for high EMI constraints and general-purpose AC switching. The 'T' suffix indicates the TO-220AB insulated package, while '8' denotes the 800 V rating. It is designed as a medium-current solution bridging lower power logic triacs and higher power industrial thyristors.

Replacement Considerations

Cross-reference with other ST T-Series Triacs such as the T1610T-8G (D2PAK) or T1610T-8I (TO-220AB Insulated) for pin-compatible or functionally equivalent alternatives depending on packaging preferences.
