S6004VS2TP

Scrs Overview

The S6004VS2TP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, designed for high-reliability power control applications. It features an RMS on-state current rating of 4 A and a rated repetitive peak off-state voltage of 600 V. The device utilizes a TO-251-3 surface-mount package for efficient thermal management and circuit board space optimization. Key electrical characteristics include a gate trigger voltage of 800 mV and a gate trigger current of 200 uA. It operates within a temperature range from -40 °C to +110 °C, with a maximum holding current of 6 mA and a non-repetitive peak on-state current capability of 100 A.

Scrs Procurement Notes

Verify the specific Littelfuse datasheet for the S6004VS2TP to confirm detailed mechanical dimensions and thermal resistance values before finalizing the design. Ensure that the ordering suffix matches the required packaging format, as variations may exist between tube and tape-and-reel configurations. Cross-reference the component marking code with official manufacturer documentation to authenticate the source and prevent counterfeit components in the supply chain.

Scrs Selection Notes

Select this SCR when a 4 A RMS current capacity at 600 V blocking voltage is required in a compact surface-mount form factor. Compare the 200 uA gate trigger current against available drive circuit capabilities to ensure reliable turn-on. Evaluate the thermal performance in the TO-251-3 package against the expected ambient temperature and duty cycle to maintain junction temperatures within the specified operational limits.

Scrs Part Context

This component belongs to the Littelfuse Sxx04xSx series of sensing SCRs, which are engineered for sensitive gate triggering. The 'VS' designation typically indicates a specific internal structure or sensitivity level compared to standard SCRs. This series is part of Littelfuse's broader portfolio of thyristors aimed at providing robust solutions for industrial and consumer power electronics applications requiring reliable switching.

Scrs Replacement Considerations

Direct replacements must match the 4 A RMS current, 600 V voltage rating, and TO-251-3 package. Verify that substitute parts offer equivalent or lower gate trigger currents to ensure compatibility with existing drive circuits. Check for identical thermal characteristics and pinout configurations to avoid PCB redesign.
