Overview
The T2550-12G-TR is a Snubberless Triac manufactured by STMicroelectronics, rated for 25 A on-state RMS current and 1200 V blocking voltage. It utilizes the D²PAK (TO-263) surface-mount package with three pins. Key electrical parameters include a maximum gate trigger current of 50 mA, a maximum gate trigger voltage of 1.3 V, and a peak gate power dissipation of 1 W. The device supports an operating temperature range from -40°C to 125°C and features a surge current rating of 252 A.
Feature Summary
- Snubberless design optimized for noise immunity and dynamic commutation in inductive, capacitive, or resistive load control applications.
- High static commutation capability and high endurance reliability suitable for demanding industrial environments.
- Compact high-voltage construction enabling efficient use in 3-phase industrial systems.
Applications
- Three-phase industrial motor control systems
- Inductive load switching circuits
- Capacitive load control applications
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets. Ensure the D²PAK footprint matches PCB layout requirements. Cross-reference the manufacturer part number directly with STMicroelectronics documentation to avoid counterfeit components.
Selection Notes
Select this component for applications requiring 1200 V blocking voltage and 25 A continuous current in a surface-mount format. Consider the 50 mA gate trigger sensitivity for driver compatibility. Evaluate thermal management needs given the 125°C maximum junction temperature limit. Compare against TO-220 variants if through-hole mounting is preferred.
Part Context
This part belongs to the T2550-12x family of Snubberless Triacs, which includes variations in packaging such as TO-220AB and insulated TO-220AB. The T2550-12G variant specifically denotes the D²PAK package, while the '-TR' suffix typically signifies tape-and-reel delivery for automated assembly processes.
Replacement Considerations
T2550-12G is the direct equivalent without the reel suffix. T2550-12I offers identical electrical specifications but uses a TO-220AB through-hole package. Substitution requires verifying package compatibility and ensuring the replacement maintains the 1200 V and 25 A ratings.
