2N6399TG

Scrs Overview

The Littelfuse 2N6399TG is a surface-mount silicon-controlled rectifier (SCR) designed for half-wave AC control applications. It features glass-passivated junctions and rugged Thermowatt construction in a TO-220AB package. The device supports a peak repetitive off-state voltage of 800 V and an on-state RMS current of 12 A at 90°C case temperature. It handles a peak non-repetitive surge current of 100 A and operates within a junction temperature range of -40 to +125°C. Key electrical characteristics include a maximum gate trigger voltage of 1.5 V, a holding current of up to 50 mA, and a turn-off time of 35 µs at elevated temperatures.

Scrs Feature Summary

• Glass-passivated junctions ensure parameter uniformity and long-term stability.
• Thermowatt construction provides low thermal resistance and high heat dissipation capabilities.
• Sensitive gate design allows for direct interfacing with microprocessors using minimal gate current.

Scrs Applications

• Motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm packaging details. The 'TG' designation indicates tube packaging containing 1000 units per box. Ensure compatibility with lead-free soldering processes as the device is Pb-Free compliant. Confirm that the selected component meets all environmental and regulatory requirements for the intended application before finalizing procurement.

Scrs Selection Notes

Select this component when an 800 V blocking voltage and 12 A RMS current rating are required in a surface-mount configuration. The TO-220AB package facilitates efficient heat transfer to a heatsink. Consider the 100 A surge capability for transient protection scenarios. Verify that the gate trigger requirements align with the driving circuit's output capabilities, noting the maximum continuous DC gate trigger voltage of 1.5 V.

Scrs Part Context

The 2N6399TG belongs to the 2N639x series of surface-mount SCRs from Littelfuse. This family offers blocking voltages ranging from 50 V to 800 V, sharing identical current ratings and package dimensions. The series utilizes a standardized CASE 221A footprint, allowing for consistent board layout across different voltage variants within the same product line.

Scrs Replacement Considerations

Direct replacements must match the 800 V rating, 12 A RMS current, and TO-220AB package. Verify that alternative devices meet the same thermal resistance and surge current specifications to ensure equivalent performance in existing designs.
