S6008R

Overview

The Littelfuse S6008R is a Silicon Controlled Rectifier (SCR) designed for efficient switching in low-current circuits. It features an 8 A RMS on-state current and a 600 V rated repetitive off-state voltage. The device utilizes a TO-220AB flange mount package with three pins, connecting the case to the anode. It operates within a temperature range of -40°C to +110°C. Key electrical characteristics include a maximum gate trigger current of 15 mA and a non-repetitive peak on-state current of 100 A. The component is lead-free compliant and suitable for applications requiring sensitive gate control.

Feature Summary

• Sensitive gate architecture allows direct interfacing with microprocessors using minimal gate current.
• Flange mount construction facilitates effective heat dissipation for thermal management.
• Glass passivated junctions provide enhanced durability against environmental stress.

Applications

• Capacitive-discharge ignition systems
• Fluid level sensors
• Strobe light controllers

Procurement Notes

Verify the specific suffix designation when ordering, as Littelfuse part numbers often include codes indicating packaging or material variations. Confirm that the TO-220AB package matches your board layout requirements. Ensure the 600V rating aligns with your circuit's peak voltage demands. Check RoHS compliance status if required by your manufacturing standards. Validate the 8A RMS current capacity against your application's continuous load.

Selection Notes

Select this SCR for applications requiring moderate power handling with precise gate control. The 600V blocking voltage suits general-purpose AC/DC switching tasks. Consider the TO-220AB package for through-hole mounting and heatsinking needs. Compare the 15mA gate trigger current against your driver capabilities. Evaluate thermal resistance requirements given the 8A RMS rating and flange mount design.

Part Context

This component belongs to Littelfuse's discrete silicon-controlled rectifier portfolio, optimized for reliable switching in electronic controls. The S6008R shares family characteristics with other 8A, 600V SCRs but differs in package and specific gate parameters. It complements Littelfuse's broader range of thyristors used in industrial and consumer electronics for power regulation and protection functions.

Replacement Considerations

Direct substitutes must match the 8A RMS current, 600V voltage rating, and TO-220AB package. Verify gate trigger current compatibility to ensure proper firing from existing drive circuits. Check holding current and dv/dt ratings for circuit stability. Alternative packages like TO-220 or D2PAK may require mechanical adaptation.
