• Driver stages for relay or LED control

Single Bipolar Transistors Procurement Notes

Verify the specific suffix D26Z against official manufacturer documentation to confirm packaging details and binning specifications. Confirm RoHS compliance status as required by project standards. Check for end-of-life notices or discontinuance alerts prior to finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with 80 V breakdown and 1 A current handling is required in a TO-92 package. Ensure the application does not exceed the 625 mW power dissipation limit without adequate heatsinking. Consider the complementary PNP variant if push-pull configurations are needed.

Single Bipolar Transistors Part Context

This part belongs to the BC639 series of NPN medium power transistors produced by onsemi. The series is widely recognized for its reliability in consumer electronics and industrial control systems. The D26Z suffix typically denotes specific tape-and-reel packaging or binning criteria defined by the manufacturer.

Single Bipolar Transistors Replacement Considerations

Direct equivalents include the BC639 from other manufacturers such as Fairchild or NXP. Verify pinout compatibility and ensure that replacement parts meet the same 80 V and 1 A ratings.
