The Microchip Technology 2N6285 is an NPN silicon power Darlington transistor designed for high-voltage and high-current applications. It features a maximum collector-emitter voltage of 100V, a maximum DC collector current of 10A, and a total power dissipation of 160W. The device exhibits a minimum DC current gain (hFE) of 750 at 10A with Vce=3V. Operating junction temperature ranges from -65°C to 200°C. It utilizes a TO-3 package and serves as the complementary counterpart to the PNP 2N6282 series.
Verify the manufacturer marking on the TO-3 package header to confirm Microchip Technology origin. Cross-reference the datasheet revision date against the component batch code. Ensure the pinout configuration matches the standard Base-Emitter-Collector arrangement specified in the official Microchip documentation before integration into PCB layouts.
Select this component when high current drive capability and elevated voltage tolerance are required in a single package. The high hFE reduces base drive requirements compared to standard bipolar transistors. Consider the TO-3 mechanical footprint and thermal resistance characteristics for heat sink design. Evaluate the complementary 2N6282 if push-pull configurations are necessary for the specific circuit topology.
This part belongs to the family of complementary silicon power Darlington transistors. It pairs with the 2N6282, 2N6283, and 2N6284 PNP devices. These components are engineered for robust performance in industrial and commercial power electronics where reliability under high stress conditions is critical.
Official complementary substitutes include the 2N6282, 2N6283, and 2N6284 PNP variants within the same product line. Verify pin compatibility and thermal specifications when substituting with generic equivalents from other manufacturers.
The minimum DC current gain (hFE) is 750, measured at a collector current of 10A and Vce=3V.
The maximum operating junction temperature (TJ) is 200°C.
