Overview
The Littelfuse S2008VS3TP is a sensitive silicon-controlled rectifier (SCR) rated for 8 A on-state current and 600 V repetitive peak off-state voltage. It features a gate trigger current of 500 µA maximum and utilizes an electrically isolated TO-220 package with a mounting tab. The device withstands a minimum high potential test of 4000 V ac rms from leads to the mounting tab, ensuring safe isolation in high-voltage applications.
Feature Summary
- Electrically isolated TO-220 package allows direct mounting to heatsinks without external insulators
- High surge capability supports non-repetitive peak forward currents up to 100 A
- Glass-passivated junction provides long-term reliability and parameter stability
Applications
- AC power control circuits requiring electrical isolation
- Solid-state relay designs
- Motor speed control systems
Procurement Notes
Verify that the component matches the specific 4000 V isolation rating indicated by the 'V' suffix in the part number. Confirm the package type is the isolated TO-220 variant. Ensure the ordering documentation specifies the correct gate sensitivity class corresponding to the 500 µA maximum trigger current requirement.
Selection Notes
Select this component when an SCR requires both high voltage blocking capability and electrical isolation between the circuit and the heatsink. The 8 A rating suits moderate power loads, while the 600 V rating handles standard industrial line voltages. Verify thermal management requirements against the specified thermal resistance values for the TO-220 package.
Part Context
This device belongs to the Teccor line of sensitive SCRs manufactured by Littelfuse. It complements the broader portfolio of power SCRs by offering lower gate drive requirements. The product line includes various packages such as TO-92, Compak, and D-Pak, with ratings spanning from 0.8 A to 10 A and voltages up to 600 V.
