S2008DS3RP

Scrs Overview

The Littelfuse S2008DS3RP is a sensitive Silicon Controlled Rectifier (SCR) from the Teccor line, designed as a half-wave unidirectional gate-controlled rectifier. It features an 8 A RMS on-state current rating and a 400 V repetitive peak off-state voltage capability. The device utilizes a D-Pak (TO-252) surface-mount package with electrical isolation between leads and the mounting tab. Key electrical parameters include a maximum DC gate trigger current of 500 µA, a peak on-state voltage of 1.6 V, and a non-repetitive surge current rating of 100 A. It operates within a junction temperature range of -40 °C to +110 °C.

Scrs Feature Summary

• Glass-passivated chip junctions for long-term reliability and parameter stability
• Electrically isolated TO-252 package allowing low-cost assembly techniques
• High sensitivity gate control requiring minimal trigger current
• RoHS compliant construction

Scrs Applications

• AC switching and phase control circuits
• Speed controls for motors
• Temperature modulation controls
• Lighting controls requiring noise immunity

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and isolation ratings. Confirm RoHS compliance status for the specific batch. Ensure the procurement documentation matches the exact part number S2008DS3RP to avoid confusion with similar series variants.

Scrs Selection Notes

Select this component for applications requiring high gate sensitivity and surface-mount integration. The 400 V rating suits medium-voltage AC control tasks. Verify thermal management requirements based on the specified case temperature limits and power dissipation curves provided in the official documentation.

Scrs Part Context

This device belongs to the Teccor sensitive SCR family, which complements standard power SCRs by offering lower gate drive requirements. The S2008DS3RP specifically represents the 8 A current class within the 400 V voltage bracket, packaged in the compact D-Pak form factor for automated surface-mount assembly.

Scrs Replacement Considerations

Direct replacements must match the 8 A IT(RMS), 400 V VDRM, and 500 µA IGT specifications. Verify that substitute devices offer equivalent electrical isolation ratings if used in grounded configurations. Check for compatible pinout assignments in the TO-252 package.
