2N6400G

Scrs Overview

The Littelfuse 2N6400G is a silicon gate-controlled thyristor (SCR) designed for half-wave AC control applications. It features glass-passivated junctions and rugged TO-220AB thermowatt construction. The device supports a peak repetitive off-state voltage of 50 V and an on-state RMS current of 16 A at 100°C case temperature. It handles a non-repetitive surge current of 160 A and operates within a junction temperature range of -40 to +125 °C. Key electrical parameters include a maximum gate trigger current of 60 mA, a holding current of up to 60 mA, and a thermal resistance from junction to case of 1.5 °C/W.

Scrs Feature Summary

• Glass-passivated junctions ensure parameter uniformity and long-term stability.
• Thermowatt construction provides low thermal resistance and high heat dissipation capabilities.
• Designed specifically for half-wave AC control applications such as motor controls and power supplies.

Scrs Applications

• Half-wave AC motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm package type and shipping quantity. The 2N6400G variant typically ships in boxes of 1000 units, while other series members may use tubes. Confirm Pb-free status and JEDEC registration requirements directly with the manufacturer or authorized distributors before finalizing procurement specifications.

Scrs Selection Notes

Select the 2N6400G when a 50 V blocking voltage rating is required for half-wave AC circuits. Ensure the application current does not exceed the 16 A RMS limit at a 100°C case temperature. Consider the 1.5 °C/W thermal resistance for heatsink design. Verify that the gate trigger requirements align with the specified 60 mA maximum at -40°C.

Scrs Part Context

The 2N6400G belongs to the 2N640xG family of surface mount and through-hole thyristors from Littelfuse. This series offers blocking voltages ranging from 50 V to 800 V. All devices in this family share similar rugged thermowatt construction and glass-passivated junction technologies, providing a scalable solution for various power control needs within the same component lineage.

Scrs Replacement Considerations

Direct replacements within the same family include the 2N6401G, 2N6402G, 2N6403G, 2N6404G, and 2N6405G, which differ primarily in their peak repetitive off-state voltage ratings. Ensure the substitute part meets the specific voltage requirements of the circuit design.
