BC141 NPN Metal Transistor 60V 1A TO-39

BC141 NPN Metal Transistor 60V 1A TO-39

The BC141 is a silicon planar epitaxial NPN transistor housed in a JEDEC TO-39 metal can. It is designed for medium-power applications where a robust package, good thermal performance and reliable switching are required. The metal case (collector connected to the case) improves heat dissipation and mechanical durability, making the BC141 suitable for repeated soldering cycles and long-term service in through-hole assemblies.

Electrically the BC141 supports up to 60 V collector-emitter voltage and 1 A continuous collector current, with a variety of gain groups offered for selection. Uses include audio output stages, driver circuits, relay and motor drivers, and general-purpose switching in industrial and consumer electronics.

Features:

• Metal TO-39 package (robust mechanical construction).
• Good thermal dissipation (case-mounted collector).
• Medium-power switching and amplification capability.
• Available in gain groups for matched circuits.
• Low saturation voltages at moderate drive currents.
• Suitable for audio and general-purpose driver stages.
