BC107B NPN Bipolar Transistor in TO 18 Package

BC107B is a general-purpose NPN bipolar transistor rated for 45 V collector-emitter voltage and 100 mA collector current. It uses a TO-18 package, giving technicians a leaded discrete transistor format commonly found in established electronic assemblies. The device provides a defined NPN option when a circuit calls for this voltage and current range. Engineers should confirm the required bias point, load conditions, voltage margin, and thermal environment before selecting it for a replacement or existing design. Its three-terminal bipolar configuration keeps bench testing and circuit tracing familiar during component-level service. BC107B is a practical choice when the specified NPN polarity, TO-18 package, and electrical limits match the board requirements. Request a quote for BC107B.
