BC487

Single Bipolar Transistors Overview

The BC487B is a single NPN bipolar junction transistor manufactured by onsemi, housed in a TO-92 (TO-226) through-hole package. It features a maximum collector-emitter voltage of 60 V and a continuous collector current rating of 500 mA. The device has a transition frequency of 200 MHz and a maximum power dissipation of 625 mW. DC current gain is specified at a minimum of 160 under test conditions of 1 A collector current and 5 V collector-emitter voltage. The saturation voltage is limited to 500 mV at 50 mA base and 500 mA collector currents. Operating junction temperature ranges from -55°C to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation, as the BC487 series includes variants like BC487B with distinct electrical parameters. Confirm component availability status, as some distributors list this part as discontinued or out of stock. Ensure the selected variant matches the required voltage and current ratings for the target circuit design before ordering.

Single Bipolar Transistors Selection Notes

Select the BC487B variant when a 60 V breakdown voltage and 500 mA current capacity are required. Compare the 200 MHz transition frequency against application bandwidth needs. Evaluate the TO-92 package thermal characteristics against the 625 mW power dissipation limit. Verify that the minimum hFE of 160 meets the circuit's gain requirements.

Single Bipolar Transistors Part Context

The BC487 series belongs to onsemi's lineup of NPN small-signal transistors. These components are designed for low-power applications requiring moderate voltage handling and current drive capabilities. The TO-92 packaging provides a cost-effective solution for through-hole PCB implementations in consumer and industrial electronics.
