BC516-D27Z

Single Bipolar Transistors Overview

The BC516-D27Z is a PNP Darlington transistor manufactured by onsemi, designed for applications requiring extremely high current gain at currents up to 1 A. It features a collector-emitter voltage of -30 V and a continuous collector current rating of -1 A. The device operates within a junction temperature range of -55 °C to +150 °C and offers a minimum DC current gain (hFE) of 30,000 at IC = -20 mA. Packaged in a TO-92-3 lead-formed case, the D27Z suffix indicates a tape and reel shipping configuration with a standard quantity of 2000 units.

Single Bipolar Transistors Feature Summary

• Engineered as a PNP Darlington pair providing exceptionally high DC current gain suitable for sensitive signal amplification
• Capable of handling continuous collector currents up to 1 A while maintaining stable operation across a wide thermal range
• Constructed as a lead-free device compliant with environmental standards

Single Bipolar Transistors Applications

• High-gain audio amplifier stages
• Switching circuits requiring substantial load current control
• General-purpose small-signal amplification

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix D27Z corresponds to the tape and reel packaging format containing 2000 units per standard roll. Confirm that the component meets Pb-Free requirements if environmental compliance is mandatory for the assembly process. Ensure the TO-92-3 package orientation matches the design footprint before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when circuit designs demand a single PNP transistor capable of delivering very high current gain without cascading multiple devices. The -30 V collector-emitter breakdown voltage limits suitability for high-voltage switching applications. Verify that the required operating current remains within the 1 A continuous limit to ensure reliable thermal performance.

Single Bipolar Transistors Part Context

This part belongs to the BC516 family of PNP Darlington transistors produced by onsemi. The base model provides robust amplification capabilities, while the D27Z variant specifically denotes the bulk tape and reel packaging option intended for automated surface mount or through-hole assembly lines.

Single Bipolar Transistors Replacement Considerations

Cross-reference with other PNP Darlington transistors offering similar hFE characteristics and -30 V ratings. Verify pinout compatibility for the TO-92-3 package to ensure direct substitution without PCB layout modifications.
