C106DG

Scrs Overview

The Littelfuse C106DG is a sensitive gate silicon controlled rectifier (SCR) from the C106 Series, housed in a TO-225AA surface-mount package. It features a peak repetitive off-state voltage of 400 V and an on-state RMS current rating of 4.0 A. The device supports an average on-state current of 2.55 A and withstands a non-repetitive surge current of 20 A. Key electrical characteristics include a maximum gate trigger current of 200 μA at 25°C and a peak forward on-state voltage of 2.2 V. Operating junction temperatures range from -40°C to +110°C.

Scrs Feature Summary

• Sensitive gate triggering for low power control applications
• Glass-passivated PNPN structure for reliability and uniformity
• Flat thermopad construction for efficient heat dissipation

Scrs Applications

• Temperature control systems
• Light dimming circuits
• Speed control mechanisms

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct shipping configuration. Confirm that the component meets RoHS compliance requirements for your assembly process. Cross-reference the part marking system to validate authenticity upon receipt.

Scrs Selection Notes

Select this SCR when a 400 V blocking voltage and 4 A RMS current capacity are required in a compact surface-mount form factor. Ensure the driving circuit can supply the specified sensitive gate trigger parameters. Verify thermal management capabilities align with the junction-to-case thermal resistance specifications.

Scrs Part Context

This component belongs to the C106 Series of thyristors designed for high-volume consumer electronics. The series offers various voltage ratings including 200 V, 400 V, and 600 V options within the same package family to simplify inventory management for common control applications.

Scrs Replacement Considerations

The C106D1G is documented as the European equivalent for the C106DG. Verify pinout compatibility and exact electrical tolerances before substituting.
