2N6404G

Scrs Overview

The Littelfuse 2N6404G is a silicon gate-controlled thyristor (SCR) in a TO-220AB package. It features a peak repetitive off-state voltage of 600 V and an average on-state current rating of 10 A at a case temperature of 100°C. The device supports a non-repetitive surge current of 160 A and operates within a junction temperature range of -40°C to +125°C. Electrical characteristics include a maximum gate trigger voltage of 2.5 V at -40°C and a holding current of up to 60 mA under cold conditions.

Scrs Feature Summary

• Glass passivated junctions for enhanced parameter uniformity and stability
• Thermowatt construction providing low thermal resistance and high heat dissipation
• Lead-free manufacturing compliant with environmental standards

Scrs Applications

• Half-wave AC control applications
• Motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm packaging details, such as tube versus box quantities. Ensure that the procurement channel sources genuine components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability.

Scrs Selection Notes

Select this component when a 600 V blocking voltage is required alongside a 10 A continuous current capacity. Consider the thermal management requirements based on the 1.5 °C/W junction-to-case resistance. Verify that the gate drive circuitry can supply the necessary trigger current across the specified operating temperature range.

Scrs Part Context

This part belongs to the 2N640x series of surface mount thyristors designed for robust performance in power control circuits. The series offers various voltage ratings from 50 V to 800 V while maintaining consistent current handling capabilities and rugged thermowatt construction for reliable operation in demanding environments.

Scrs Replacement Considerations

Consult the official datasheet for compatible substitutes within the 2N640x family, such as the 2N6403G or 2N6405G, which share identical mechanical and thermal specifications but differ in voltage ratings.
