2N6402G

Scrs Overview

The Littelfuse 2N6402G is a silicon gate-controlled thyristor (SCR) designed for half-wave AC control applications. It features glass-passivated junctions and rugged Thermowatt construction for high heat dissipation. The device offers a peak repetitive off-state voltage of 200 V and an on-state RMS current of 16 A at 180° conduction angles with the case held at 100°C. It supports a peak non-repetitive surge current of 160 A and operates within a junction temperature range of -40°C to +125°C. Packaged in a TO-220AB flange mount configuration, it provides reliable performance for motor controls, heating systems, and power supplies.

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping quantity. The datasheet indicates that the 'G' suffix denotes lead-free status, while other suffixes may alter the shipping format or physical mounting style. Confirming these details ensures compatibility with assembly requirements and regulatory standards.

Scrs Selection Notes

Select this component based on the required blocking voltage and current handling capabilities. Ensure the thermal management design accommodates the specified thermal resistance and maximum junction temperature limits. Verify that the gate trigger characteristics align with the driving circuit specifications for reliable turn-on across the operating temperature range.

Scrs Part Context

This part belongs to the 2N640x series of surface-mount capable thyristors from Littelfuse. The series covers blocking voltages ranging from 50 V to 800 V, allowing designers to choose the appropriate voltage rating for their specific application while maintaining consistent packaging and thermal characteristics across the family.

Scrs Replacement Considerations

Direct replacements within the same series include the 2N6400G, 2N6401G, 2N6403G, 2N6404G, and 2N6405G, which share identical current ratings but differ in blocking voltage. The 2N6403TG variant offers a higher voltage rating of 400 V in a similar package.
