2N6399G

Scrs Overview

The Littelfuse 2N6399G is a surface mount thyristor designed for half-wave AC control applications. It features glass passivated junctions and rugged Thermowatt construction for low thermal resistance and high heat dissipation. The device supports blocking voltages up to 800 V with an on-state RMS current of 12 A at TC = 90°C. Peak non-repetitive surge current reaches 100 A, while the operating junction temperature range spans from -40°C to +125°C. Thermal resistance from junction to case is 2.0 °C/W.

Scrs Feature Summary

• Glass passivated junctions ensure greater parameter uniformity and stability
• Thermowatt construction provides low thermal resistance and high durability
• Surface mount design suitable for compact circuit layouts

Scrs Applications

• Motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific ordering suffix (e.g., G or TG) against the manufacturer's datasheet to confirm package style and shipping quantity. Confirm that the component meets Pb-Free requirements if environmental compliance is necessary for the assembly process. Cross-reference JEDEC registered data points for critical electrical parameters before finalizing procurement specifications.

Scrs Selection Notes

Select this component when a surface mount SCR with 800 V blocking capability is required. Ensure the application allows for a maximum junction temperature of 125°C and can accommodate the specified gate trigger characteristics. Verify that the PCB layout supports the TO-220AB package dimensions and thermal management needs for 12 A RMS operation.

Scrs Part Context

This part belongs to the 2N639x series of surface mount thyristors from Littelfuse. The series includes variants with different voltage ratings, such as 50 V, 100 V, and 400 V. All devices in this family share similar physical construction and thermal characteristics, differing primarily in their peak repetitive off-state voltage capabilities.

Scrs Replacement Considerations

Direct replacements within the same series include the 2N6394G, 2N6395G, and 2N6397G, provided the lower voltage ratings are acceptable for the circuit design. Verify pinout compatibility and thermal resistance values when substituting.
