2N6397G

Scrs Overview

The Littelfuse 2N6397G 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 offers a peak repetitive off-state voltage of 400 V and an on-state RMS current rating of 12 A at a case temperature of 90°C. It supports a peak non-repetitive surge current of 100 A and operates within a junction temperature range of -40 to +125 °C. The component utilizes a TO-220AB package with four terminals.

Scrs Feature Summary

• Glass-passivated junctions ensure parameter uniformity and stability
• Thermowatt construction provides low thermal resistance and high durability
• Surface mount design suitable for space-constrained PCB layouts

Scrs Applications

• Motor controls
• Heating controls

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package style and shipping quantity. Confirm RoHS compliance status and lead-free certification requirements before finalizing procurement orders. Ensure the selected variant matches the required thermal management specifications for the target application environment.

Scrs Selection Notes

Select this component based on the 400 V blocking voltage requirement and 12 A continuous current capacity. Evaluate the thermal resistance characteristics relative to the expected ambient operating conditions. Consider the surface mount form factor when designing the PCB footprint and soldering profile.

Scrs Part Context

This part belongs to the 2N639x series, which includes variants with different voltage ratings such as 50 V, 100 V, and 800 V. All members share similar current handling capabilities and physical packaging styles. The series is engineered for robust performance in industrial power control environments requiring reliable switching characteristics.

Scrs Replacement Considerations

Compatible substitutes include other 2N639x series devices like the 2N6394G or 2N6395G, provided the voltage ratings meet the circuit requirements. Verify pinout compatibility and thermal resistance values when cross-referencing with equivalent components from other manufacturers.
