The 2N5874 is an NPN silicon power transistor manufactured by Microchip Technology, housed in a TO-66 metal can package. It is rated for a maximum collector current of 7 A and a collector-emitter breakdown voltage of 60 V. The device is designed for high-power switching and amplification applications within the discrete semiconductor category.
Verify the manufacturer origin carefully, as the 2N5874 designation is historically associated with New Jersey Semiconductor. Confirm that the specific unit supplied matches the required TO-66 package dimensions and electrical ratings. Ensure compliance with any applicable military or industrial specifications if the application demands high reliability standards.
Select this component when a hermetically sealed TO-66 package is required for high-current NPN switching. Compare against similar parts like the 2N6316 or 2N5873 which share identical electrical ratings but may differ in manufacturing source. Ensure the thermal management design accommodates the power dissipation limits inherent to the TO-66 form factor.
This part belongs to the family of standard NPN power transistors utilizing the legacy 2N numbering system. It serves as a general-purpose high-power device often used in replacement scenarios for older equipment designs. The TO-66 package provides superior thermal conductivity and environmental sealing compared to plastic alternatives.
