onsemi Small Signal NPN Bipolar Junction Transistor 100 mA 30 V 3-Pin TO-92 BC548CTA

onsemi BC548CTA is a small signal NPN bipolar junction transistor designed for general-purpose amplification and switching applications. It is housed in a compact 3-pin TO-92 package, allowing easy through-hole mounting on printed circuit boards for electronic devices.

This transistor supports a maximum DC collector current of 100 mA and a collector-emitter voltage up to 30 V, enabling it to operate reliably in a variety of low power electronic circuits. The maximum power dissipation is 500 mW, which ensures stable thermal performance during operation.

The device offers a minimum DC current gain (hFE) of 110, making it efficient for amplification purposes. It operates safely between -55°C and 150°C, allowing its use in harsh environmental conditions typically encountered in industrial, consumer electronics, and laboratory instrumentation.

With a maximum transition frequency (ft) of 1 MHz, the BC548CTA is suited for low frequency switching and amplification tasks. Its physical dimensions of approximately 21.77 mm in height, 5.2 mm in length, and 4.19 mm in width contribute to its integration in compact electronic assemblies.
