Overview
The Littelfuse S2008DS3TP is a sensitive silicon-controlled rectifier (SCR) rated for 8 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a gate trigger current of 500 µA maximum at 25 °C, with an operating temperature range from -40 °C to +110 °C. The device utilizes a TO-252 D-Pak surface-mount package and incorporates glass-passivated junctions for parameter stability. Key electrical characteristics include a non-repetitive surge current capability of 100 A and a holding current of 8 mA maximum.
Feature Summary
- Glass-passivated chip junctions ensure long-term reliability and protection against contamination.
- High surge capability supports demanding transient load conditions.
- Surface-mount D-Pak package facilitates automated assembly.
Applications
- Half-wave unidirectional gate-controlled rectification
- General-purpose power control circuits
- Sensitive switching applications requiring low gate drive currents
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's official documentation to confirm tape-and-reel packaging availability. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering part number matches the required voltage and current ratings for the intended circuit design.
Selection Notes
Select this component when an 8 A RMS current rating and 600 V blocking voltage are required in a surface-mount form factor. The 500 µA gate sensitivity allows for direct interfacing with standard logic or low-power drivers. Verify thermal management requirements based on the specified case temperature limits for the chosen RMS current load.
Part Context
This device belongs to the Teccor line of sensitive SCRs, which complement the manufacturer's broader power SCR portfolio. The product family offers ratings from 0.8 A to 10 A and voltages up to 600 V. The S2008DS3TP specifically addresses the need for high-current surface-mount thyristors with defined gate sensitivity profiles.
Replacement Considerations
Consult the manufacturer's catalog for electrically equivalent devices within the same series. Verify that any substitute maintains the 8 A IT(RMS), 600 V VDRM, and compatible TO-252 package dimensions.
