BC516

Single Bipolar Transistors Overview

The BC516 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 (VCEO) of -30 V and a continuous collector current (IC) of -1 A. The device operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a minimum DC current gain (hFE) of 30,000 at IC = -20 mA and a transition frequency (fT) typical value of 200 MHz. Total device dissipation is rated at 625 mW.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix when purchasing. The standard package is TO-92. Bulk quantities are available in tape and reel formats with specific suffixes such as D27Z. Confirm lead times and availability directly with authorized distributors or the manufacturer, as production status may vary.

Single Bipolar Transistors Selection Notes

Select this component when a single PNP device must provide very high current gain without external feedback networks. Ensure the application voltage does not exceed the -30 V collector-emitter rating. Consider the thermal resistance values if operating near maximum power dissipation limits in enclosed environments.

Single Bipolar Transistors Part Context

This component belongs to the family of discrete bipolar transistors offered by onsemi. It utilizes a monolithic Darlington configuration to achieve superior gain compared to standard single-transistor designs. The device is housed in a TO-92-3 plastic package, suitable for through-hole mounting on printed circuit boards.

Single Bipolar Transistors Replacement Considerations

Check datasheets for equivalent PNP Darlington transitors from other manufacturers. Verify that replacement parts meet or exceed the -30 V VCEO, -1 A IC, and hFE specifications. Ensure pinout compatibility with the original TO-92-3 arrangement.
