BC516_D75Z

Single Bipolar Transistors Overview

The BC516_D75Z is a PNP silicon small-signal 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 is housed in a TO-92 through-hole package with three terminals. Key electrical characteristics include a minimum DC current gain (hFE) of 30,000 and a transition frequency (fT) of 200 MHz. It operates within a temperature range of -55 °C to +150 °C.

Single Bipolar Transistors Feature Summary

• High current gain capability suitable for sensitive signal amplification
• Robust thermal performance allowing operation at elevated temperatures
• Standardized through-hole packaging for reliable circuit board integration

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications requiring high input impedance
• Driver stages for power transistors or relays

Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking matches onsemi specifications. Confirm the suffix _D75Z corresponds to the correct tape-and-reel or bulk packaging variant required for your assembly process. Ensure the component meets RoHS compliance standards if mandated by your design requirements. Cross-reference datasheets from authorized distributors to confirm pinout consistency.

Single Bipolar Transistors Selection Notes

Select this component when a single PNP transistor offers insufficient current gain for the application. The Darlington configuration provides high beta values, reducing base drive requirements. Compare against standard bipolar transistors if lower saturation voltage is prioritized over gain. Consider the TO-92 package constraints for thermal dissipation in enclosed environments.

Single Bipolar Transistors Part Context

This part belongs to the BC51x series of Darlington transistors, which are widely used in analog and digital switching applications. The BC516 specifically denotes the PNP polarity variant with defined current and voltage ratings. It is functionally complementary to NPN counterparts like the BC517, facilitating push-pull output stage designs.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the BC516 from other manufacturers such as Fairchild or STMicroelectronics, provided pinouts and electrical limits match. Verify that alternative packages maintain the same thermal resistance and mechanical dimensions for direct replacement without PCB modification.
