Procurement Notes
Verify that the D26Z suffix corresponds to the Tape and Reel packaging option with 2,000 units per reel as specified in the datasheet. Confirm the component origin matches the manufacturer's documentation, noting historical transitions between Fairchild Semiconductor and onsemi manufacturing lines.
Selection Notes
Select this component when circuit designs demand high current gain without complex biasing networks. Ensure thermal management accommodates the 625 mW power dissipation limit in the TO-92 package. Verify that the 40 V collector-emitter breakdown voltage exceeds the maximum expected circuit voltage.
Part Context
This part belongs to the 2N6427 series of NPN Darlington transistors. It is functionally similar to the MPSA14 but optimized for specific gain characteristics. The device is sourced from Process 05, indicating a specific manufacturing technology node used by the producer.

FAQ
What is the minimum DC current gain (hFE) for the 2N6427?
The minimum DC current gain is 10,000 at IC = 10 mA and VCE = 5.0 V.
Does the D26Z suffix indicate a different electrical function?
No, the D26Z suffix specifies the Tape and Reel packaging configuration containing 2,000 units per reel; it does not alter the electrical characteristics.
