Overview
The Central Semiconductor 2N6043 PBFREE is an NPN silicon power Darlington transistor housed in a TO-220 package. It features a collector-emitter voltage of 60 V and a continuous collector current rating of 8.0 A, with a peak collector current capability of 16 A. The device dissipates up to 75 W at 25°C case temperature, supported by a thermal resistance of 1.67 °C/W. Operating junction temperatures range from -65°C to +150°C. Electrical characteristics include a minimum DC current gain (hFE) of 1,000 at 4.0 A, a transition frequency (fT) of 4.0 MHz, and a collector-base capacitance of 200 pF.
Feature Summary
- High-gain Darlington configuration for efficient amplification
- Epitaxial base process construction for robust performance
- Flange-mountable TO-220 package design
Applications
- General purpose amplifier applications
- Power switching circuits
- Audio output stages
Procurement Notes
Verify the specific plating type required for your assembly process, as the standard designation allows for either lead-free or tin/lead plated products depending on availability. Confirm that the component meets RoHS compliance standards if restricted substances are prohibited in your manufacturing environment. Ensure the TO-220 mounting interface matches your heat sink specifications prior to procurement.
Selection Notes
Select this component when a high-current NPN switch or amplifier is needed within a 60 V limit. The 8.0 A continuous rating and 75 W dissipation capacity suit medium-power designs. Verify that the 1,000 minimum hFE meets your drive requirements. Consider the complementary 2N6040 PNP variant if a matched pair is necessary for push-pull configurations.
Part Context
This part belongs to the Central Semiconductor 2N6040 through 2N6045 series of complementary silicon power transistors. The series utilizes epitaxial base technology designed for general-purpose amplifier roles. While the 2N6043 provides the NPN option, the series includes PNP counterparts with varying voltage ratings, forming a complete family for balanced circuit designs.
Replacement Considerations
Central Semiconductor has classified the 2N6043 as End of Life (EOL). No suggested replacement part numbers are provided in the official discontinuation notice. Designers must identify alternative sources or equivalent components independently.
