Overview
The STMicroelectronics T2050H-6G is a bidirectional triac in the H-series, housed in a D2PAK (TO-263) surface-mount package. It supports an RMS on-state current of 20 A and a non-repetitive peak surge current of 210 A. The device offers a rated repetitive peak off-state voltage of 600 V with a maximum on-state voltage of 1.5 V. Gate triggering requires a maximum current of 50 mA at 1 V. Operating temperatures range from -40°C to +150°C, featuring a holding current of 75 mA and a peak gate power dissipation of 1 W.
Feature Summary
- Snubberless design capability for simplified circuit implementation
- High thermal performance utilizing internal ceramic pad insulation
- Robust commutation characteristics across multiple quadrants
Applications
- General purpose mains power AC switching
- Solid state relays
- Motor speed control circuits
Procurement Notes
Verify the specific suffix 'G' against official datasheets to confirm RoHS compliance status and pinout configuration. Ensure the ordering quantity aligns with manufacturer minimum order requirements for the D2PAK tube or reel packaging options available through authorized channels.
Selection Notes
Select this component when a 20 A RMS current rating and 600 V blocking voltage are required in a surface-mount form factor. The high junction temperature limit of 150°C makes it suitable for applications demanding robust thermal management without excessive heatsinking compared to lower-rated alternatives.
Part Context
This part belongs to the T10xxH/20xxH/30xxH series of Snubberless Triacs designed for general-purpose AC power control. It shares functional similarities with the T2050H-6T but differs in physical mounting style, offering a compact surface-mount solution for automated PCB assembly processes.
Replacement Considerations
Direct substitutes include the T2050H-6T for through-hole compatibility or other H-series triacs with matching 20 A ratings. Verify that alternative packages maintain equivalent thermal resistance and pin configurations for direct board replacement.
FAQ
What is the maximum operating junction temperature?
The maximum operating junction temperature is +150°C.
Does this device require a snubber circuit?
No, the T2050H-6G features a Snubberless design, eliminating the need for external RC snubber networks in most applications.
What is the package type?
It is packaged in a D2PAK (also known as TO-263) surface-mount case.
