2N6397TG

Scrs Overview

The Littelfuse 2N6397TG is a surface-mount silicon-controlled rectifier (SCR) 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 a peak repetitive off-state voltage of 400 V and an on-state RMS current of 12 A at 90°C case temperature. It operates within a junction temperature range of -40 to +125°C and utilizes a TO-220AB package.

Scrs Feature Summary

• Glass passivated junctions ensure parameter uniformity and stability
• Thermowatt construction provides low thermal resistance and durability
• Sensitive gate design allows direct interfacing with microprocessors

Scrs Applications

• Motor controls
• Heating controls
• Power supplies

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package style and lead-free status. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the selected part number matches the required blocking voltage and current ratings for the intended circuit design before finalizing procurement.

Scrs Selection Notes

Select this component based on its 400 V blocking capability and 12 A RMS current rating. Consider the thermal resistance of 2.0 °C/W when designing heatsinking solutions. Verify that the gate trigger characteristics align with the driving circuit's output capabilities. Ensure the operating environment stays within the specified -40 to +125°C junction temperature range.

Scrs Part Context

This device belongs to the 2N639x series of surface-mount thyristors from Littelfuse. The series offers blocking voltages ranging from 50 V to 800 V, allowing designers to choose appropriate voltage ratings for various AC control applications while maintaining consistent package dimensions and thermal performance across the family.

Scrs Replacement Considerations

Compatible substitutes include other 2N639x series parts such as the 2N6394, 2N6395, or 2N6399, provided their voltage ratings meet the circuit requirements. Verify pinout compatibility and thermal characteristics when substituting.
