Overview
The 2N6128 is an NPN silicon power transistor manufactured by Microchip Technology. It features a collector-emitter voltage (VCEO) of 45 V and a rated collector current of 10 A. The device operates within a junction temperature range up to +150°C and has a transition frequency (fT) of 50 MHz. It is housed in a TO-61 package, designed for high-power applications requiring robust switching capabilities.
Feature Summary
- High current handling capability with a 10 A rated collector current
- Operates at elevated temperatures with a maximum junction temperature of +150°C
- Utilizes NPN silicon construction for reliable power switching
Applications
- Power switching circuits
- Amplifier stages
- Industrial control systems
Procurement Notes
Verify the manufacturer designation on the component marking, as the 2N6128 part number is historically associated with multiple vendors including Motorola and New Jersey Semi-Conductor. Confirm that the specific unit supplied matches the Microchip Technology specification sheet regarding pinout and electrical characteristics before integration into designs.
Selection Notes
Select this component when a 10 A NPN power transistor is required with a 45 V collector-emitter breakdown voltage. Ensure the thermal management solution supports operation at case temperatures up to 25°C for full 70 W dissipation ratings. Verify compatibility with the TO-61 package footprint during PCB layout.
Part Context
The 2N6128 belongs to the family of general-purpose NPN silicon power transistors. It shares similar structural characteristics with other TO-61 packaged devices but is distinct in its specific 45 V rating and 10 A current capacity compared to higher voltage variants like the 2N5937 series.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with original datasheets from other manufacturers such as Motorola or New Jersey Semi-Conductor is recommended to identify compatible equivalents.
