Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as Bourns may distribute components originally manufactured by other semiconductor providers such as ON Semiconductor or Fairchild under their own branding. Confirm that the 'S' suffix denotes the standard reel packaging format rather than a functional variation. Ensure the datasheet matches the electrical characteristics of the BDW94C specification if cross-referencing with other vendors. Check for RoHS compliance status on the specific batch documentation provided by the supplier.

Single Bipolar Transistors Selection Notes

Select this component when a PNP Darlington transistor with 12A current capacity and 100V breakdown voltage is required. The TO-220AB package allows for direct heatsinking. Consider thermal resistance requirements for the specific application environment. Verify pinout compatibility with existing PCB footprints. Compare against NPN equivalents if circuit topology requires polarity inversion. Ensure the operating temperature range meets system specifications.

Single Bipolar Transistors Part Context

The BDW94 series belongs to a family of high-power PNP Darlington transistors widely used in industrial and consumer electronics. These devices are often sourced from major semiconductor manufacturers like ON Semiconductor and distributed by passive component suppliers like Bourns. The series is known for its reliability in high-current applications. The BDW94-S variant specifically refers to the packaged form factor available through Bourns distribution channels.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitute part numbers include BDW94C, BDW94CF, and BDW94CFP. These variants share identical electrical specifications but may differ in packaging style or manufacturer origin. Verify pinout and thermal characteristics before substitution.
