Overview
The T830-8FP is an 8 A Snubberless Triac designed for general-purpose AC switching applications requiring high commutation capability. It features a rated repetitive off-state voltage (VDRM) of 800 V and operates in a TO-220-3 FP through-hole package. Key electrical parameters include a maximum holding current (Ih) of 30 mA, a gate trigger voltage (Vgt) of 1 V, and a gate trigger current (Igt) of 30 mA. The device exhibits a static dV/dt rating exceeding 2000 V and maintains a maximum off-state leakage current of 50 mA under specified conditions.
Feature Summary
- Snubberless design eliminates the need for external RC snubber circuits when operating within defined limits
- High static and dynamic commutation capability for reliable switching performance
- Provides UL certified insulation rated at 1500 V rms
Applications
- General purpose AC on/off switching functions
- Applications requiring high commutation capability without snubber networks
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official STMicroelectronics documentation. Confirm that the received device matches the specified TO-220-3 FP package and electrical ratings. Ensure compliance with RoHS directives and ECOPACK standards as indicated in the product specifications before integration into final assemblies.
Selection Notes
Select this component for designs necessitating robust AC control with minimal external passive components. The 800 V blocking voltage suits standard mains voltage applications. Verify that the load current remains within the 8 A RMS limit and that the gate drive circuit can supply the required 30 mA trigger current to ensure reliable turn-on across the operating temperature range.
Part Context
This device belongs to the T830 series of Snubberless Triacs from STMicroelectronics. It is distinct from similar models like the T835 series by its specific packaging and parameter set. The T830-8FP utilizes the TO-220-3 FP leaded package, differentiating it from surface-mount variants such as the T835-8G found in D2PAK packages.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult official STMicroelectronics documentation for qualified alternatives or verify compatibility with other 8 A, 800 V Snubberless Triacs from the same family.
