2N6478

Overview

The 2N6478 is a single NPN bipolar junction transistor manufactured by Harris Corporation. It is designed for through-hole mounting in TO-220-3 packages. The device features a maximum collector-emitter voltage of 150 V and a continuous collector current rating of 2.5 A. Thermal performance is characterized by a total power dissipation capacity of 50 W under specified conditions.

Feature Summary

• NPN polarity configuration for standard switching and amplification applications
• Through-hole compatible TO-220-3 package design for robust mechanical mounting
• High voltage handling capability suitable for medium-power circuit topologies

Applications

• General purpose switching circuits
• Linear amplifier stages
• Power regulation modules

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Central Semiconductor Corp. Ensure the component matches the specific electrical ratings of 150 V and 2.5 A. Confirm the package type is TO-220-3 and check for any suffix variations that may indicate different thermal or electrical grades.

Selection Notes

Select this component when a high-voltage NPN transistor with moderate current handling is required. The TO-220-3 package facilitates heat dissipation for power applications up to 50 W. Consider the 150 V breakdown voltage for circuits operating below this threshold. Verify compatibility with existing PCB footprints and thermal management requirements.

Part Context

This component belongs to the family of single bipolar transistors. It serves as a discrete active element for controlling current flow in electronic systems. The part number 2N6478 identifies the specific NPN variant within the broader transistor classification used in industrial and commercial electronics.

Replacement Considerations

Central Semiconductor Corp produces the SL variant with identical specifications. Cross-reference datasheets to confirm pinout and thermal resistance match before substitution.
