BC516_D74Z is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS PNP DARL 30V 1A TO-92-3. Review the specifications below when checking this part for your BOM.
The BC516_D74Z is a small signal NPN Darlington transistor manufactured by onsemi. It features a maximum collector current of 1 A and a collector-emitter breakdown voltage of 30 V. The device utilizes a TO-92 cylindrical package with three through-hole terminals. Key electrical characteristics include a minimum DC current gain (hFE) of 30,000 and a nominal transition frequency (fT) of 200 MHz. The component operates at temperatures up to 150 °C and is constructed from silicon.
Verify the manufacturer marking and date code against official onsemi documentation. Confirm the package type matches the specified TO-92 form factor. Ensure the part number suffix corresponds to the correct variant. Check for compliance with relevant environmental standards if required by the design specifications.
Select this component when a single NPN transistor with high current gain is needed. The 1 A rating supports moderate load currents. Consider thermal management for continuous operation near maximum ratings. Compare with similar Darlington pairs if higher voltage ratings are required.
This component belongs to the family of small signal bipolar transistors. It serves as a discrete semiconductor solution for analog and digital circuit designs. The TO-92 package allows for easy integration into through-hole PCB layouts. It is commonly used in consumer electronics and industrial control systems.
