Overview
The T820T-6I is an 8 A Snubberless™ and logic level Triac manufactured by STMicroelectronics. It features a rated repetitive off-state voltage (VDRM) of 600 V and supports through-hole mounting in a TO-220AB-3 package. Key electrical parameters include an on-state RMS current (It RMS) of 8 A, a non-repetitive peak on-state current of 63 A, and an on-state voltage of 1.6 V. The device operates within a temperature range of -40 °C to +150 °C, with a maximum holding current of 25 mA and a gate trigger current of 20 mA.
Feature Summary
- Snubberless design enables direct control from logic devices without external RC snubber networks.
- High static and dynamic commutation capability ensures reliable switching performance.
- Low thermal resistance achieved through clip bonding technology for efficient heat dissipation.
Applications
- General purpose AC switching applications requiring high commutation capability
- On/off or phase angle control functions in value-sensitive appliances
- Motor control circuits in power tools and kitchen aids
Procurement Notes
Verify the specific ordering suffix to confirm package type and compliance status. Confirm RoHS directive adherence and UL certification file references before integration. Ensure the procurement channel provides valid traceability documentation for the TO-220AB insulated package variant.
Selection Notes
Select this component when a medium current Triac with logic-level gate drive compatibility is required. The 600 V rating suits standard AC line voltages. Verify that the 8 A RMS current meets the load requirements and that the TO-220AB package fits the available thermal management space.
Part Context
This part belongs to the T8T series of Triacs designed for general-purpose AC switching. The series offers optimized performance for value-sensitive appliances while maintaining robust electrical characteristics suitable for demanding commutation environments.
Replacement Considerations
Consider the T820W for higher voltage ratings up to 800 V. Evaluate other T8T series variants if different gate sensitivity levels or package configurations are needed for the specific application constraints.
