S6008VS3

Overview

The S6008VS3 is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-reliability power control applications. It features an 8 A RMS on-state current rating and a 600 V repetitive peak off-state voltage capability. The device utilizes a sensitive gate structure with a maximum gate trigger current of 500 µA and a gate trigger voltage of 800 mV. Packaged in a TO-251AA (DPAK) surface-mount format, it supports through-hole mounting styles within its series family. The component operates within a junction temperature range of -40 °C to +110 °C, ensuring stable performance in demanding industrial environments.

Feature Summary

• Sensitive gate architecture enabling reliable triggering with low input drive requirements
• Robust thermal management capabilities inherent to the TO-251AA surface-mount package design
• High surge current handling capacity suitable for inductive load switching applications

Applications

• Industrial motor control circuits requiring precise phase-angle firing
• Solid-state relay designs utilizing thyristor-based switching elements
• AC power regulation systems for heating and lighting control

Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm exact pinout and packaging variations. Ensure the procurement channel provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the part number with the latest datasheet revision history to confirm parameter consistency before finalizing supply agreements.

Selection Notes

Select this component when a surface-mount SCR with moderate current ratings and sensitive gate sensitivity is required. Compare the TO-251AA package thermal resistance against available PCB copper area to ensure adequate heat dissipation. Evaluate the 600 V blocking voltage margin relative to the maximum line voltage peaks in the target application circuit to prevent premature breakdown.

Part Context

This device belongs to the Sxx08xSx series of silicon controlled rectifiers from Littelfuse. The series is characterized by standardized electrical parameters across various package options, allowing designers to interchange form factors while maintaining consistent current and voltage ratings. The S6008VS3 specifically adapts these characteristics for surface-mount assembly processes.

Replacement Considerations

Direct replacements include the S6008VS3TP variant, which shares identical electrical specifications but differs in tube packaging. Verify mechanical footprint compatibility when substituting with other TO-251AA thyristors from different manufacturers.
