Overview
The Littelfuse S2006VS3TP is a sensitive silicon-controlled rectifier (SCR) designed for half-wave unidirectional gate-controlled rectification. It features an electrically isolated TO-220 package with a glass-passivated chip junction for parameter stability. The device supports a maximum on-state current of 6 A and offers a repetitive peak off-state voltage rating of 600 V. Key electrical characteristics include a DC gate trigger current of 500 µA, a peak one-cycle forward surge current capability of 100 A, and a typical holding current of 0.8 mA. The component operates within a junction temperature range of -40 °C to +110 °C.
Feature Summary
- Electrically isolated TO-220 package allows safe mounting to heatsinks without external insulators
- Glass-passivated junction provides rugged protection against contamination and ensures long-term reliability
- High surge current capability suitable for demanding transient conditions
- RoHS compliant construction
Applications
- AC power control circuits
- Lighting dimmer applications
- Motor speed control systems
- Solid-state relay inputs
Procurement Notes
Verify the specific suffix configuration against the manufacturer's official documentation to confirm isolation ratings and lead form. Ensure the ordering part number matches the required voltage and gate sensitivity specifications for the target circuit design before finalizing procurement.
Selection Notes
Select this component when high-voltage blocking capability and electrical isolation are required in a compact surface-mount compatible through-hole package. The 500 µA gate sensitivity suits low-power triggering interfaces. Verify thermal management requirements based on the RMS current derating curves provided in the datasheet.
Part Context
This part belongs to the Teccor line of sensitive SCRs manufactured by Littelfuse. It is part of a broader family offering various current ratings from 0.8 A to 10 A and voltage ratings up to 600 V. The 'VS' designation indicates the specific voltage rating and isolation type within this product series.
Replacement Considerations
Direct replacements must match the 6 A current rating, 600 V blocking voltage, and isolated TO-220 package. Verify that substitute devices maintain equivalent gate trigger current and surge capabilities to ensure circuit compatibility.
