2N6405G

Scrs Overview

The Littelfuse 2N6405G is a silicon gate-controlled thyristor in a TO-220AB package, rated for a peak repetitive off-state voltage of 800 V. It supports an on-state RMS current of 16 A and an average on-state current of 10 A at a case temperature of 100°C. The device features glass-passivated junctions and thermowatt construction for low thermal resistance (1.5 °C/W junction-to-case). Electrical characteristics include a maximum gate trigger voltage of 1.5 V at 25°C and a holding current of 40 mA. It operates within a junction temperature range of -40 to +125°C and withstands a non-repetitive surge current of 160 A.

Scrs Feature Summary

• Glass-passivated junctions ensure parameter uniformity and stability
• Thermowatt construction provides low thermal resistance and high heat dissipation
• Designed for half-wave AC control applications

Scrs Applications

• Motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific part number suffix 'G' confirms lead-free compliance as documented in the official Littelfuse datasheet. Confirm the package style matches the required TO-220AB form factor for your PCB or chassis mounting constraints. Ensure the 800V blocking voltage rating aligns with your circuit's peak reverse voltage requirements. Check that the 16A RMS current capacity meets your load demands under specified thermal conditions.

Scrs Selection Notes

Select this component when an 800V blocking capability is required alongside 16A RMS current handling in a through-hole TO-220AB package. Consider the 1.5 °C/W thermal resistance for heatsinking calculations. Verify that the gate trigger characteristics suit your drive circuitry. Compare against other members of the 2N640x series if different voltage ratings are needed.

Scrs Part Context

The 2N6405G belongs to the 2N6400 series of surface mount and through-hole thyristors from Littelfuse. This family offers various voltage ratings from 50V to 800V while maintaining consistent current and thermal performance characteristics across the lineup.

Scrs Replacement Considerations

Other parts in the 2N640x series share identical current and thermal specifications but differ in voltage ratings. Direct substitutes must match the 800V rating and TO-220AB package.
