BC548A

Single Bipolar Transistors Overview

The onsemi BC548A is an NPN epitaxial silicon planar transistor housed in a TO-92-3 through-hole package. It features a maximum collector-emitter voltage of 30 V and a continuous collector current of 100 mA. The device dissipates up to 500 mW with a junction temperature rating of 150°C. Its transition frequency is 300 MHz, and the minimum DC current gain (hFE) is 110 at 2 mA and 5 V. The collector cutoff current is limited to 15 nA.

Single Bipolar Transistors Procurement Notes

Verify part authenticity against official onsemi documentation due to discontinued status. Confirm package marking matches BC548A specifications. Check for RoHS compliance certificates if required by project standards. Ensure sourcing channels provide traceable manufacturing data. Validate that the component meets the specific hFE bin requirements for the intended circuit design.

Single Bipolar Transistors Selection Notes

Select this component when a 30 V NPN transistor with moderate gain is required. Compare hFE ranges against other variants like BC548B or C if higher amplification is needed. Consider thermal dissipation limits in enclosed designs. Verify compatibility with existing PCB footprints for TO-92 packages. Evaluate alternative manufacturers if supply chain stability is a concern.

Single Bipolar Transistors Part Context

The BC548A belongs to the broader BC546–BC550 family of NPN transistors produced by onsemi. This series offers various voltage ratings and gain bins to suit different design needs. The A variant specifically provides a minimum hFE of 110, distinguishing it from higher-gain options. It serves as a standard solution for general electronic applications requiring robust small-signal handling.
