Overview
The STMicroelectronics T810T-8G is a Logic level T-series Triac in a surface-mount D²PAK package. It features an RMS on-state current of 8 A and a repetitive peak off-state voltage of 800 V, with a non-repetitive surge capability of 900 V. The device supports a maximum junction temperature of 150 °C and operates across a range from -40 °C to +150 °C. Key electrical parameters include a gate trigger current (IGT) of 10 mA maximum, a holding current (IH) of 15 mA maximum, and a critical rate of rise of on-state current (dl/dt)c of 100 A/µs at 25 °C.
Feature Summary
- Logic level design enabling direct microcontroller control via low gate trigger current
- High commutation performance on resistive loads with three-quadrant operation
- Extended thermal margin supporting a maximum junction temperature of 150 °C
- ECOPACK2 compliant packaging that is halogen-free and meets 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. The 'TR' suffix indicates tape and reel delivery, while the absence of a suffix denotes tube packaging. Confirm the exact part number against the datasheet to ensure the correct packing quantity and delivery mode are obtained for your manufacturing requirements.
Selection Notes
Select this component for applications requiring high EMI constraints and compact SMT designs. The Logic level characteristic allows simplified circuitry by driving directly from MCUs. Ensure the thermal management design accommodates the 150 °C junction limit and verify that the load conditions remain within the specified 8 A RMS and 900 V surge ratings.
Part Context
This device belongs to STMicroelectronics' T-series Triacs, which are optimized for high EMI constraints. The T810T-8G variant specifically utilizes the D²PAK surface-mount package to facilitate automated manufacturing and compact board layouts compared to through-hole alternatives.
Replacement Considerations
The T810T-8G-TR is the tape and reel version of the same component. Other variants in the T810T series may offer different packages or current ratings but share similar logic-level characteristics.
