2N3055 PDF Specs and Replacement
The 2N3055 is a classic NPN power bipolar junction transistor widely used in linear and switching applications. Built in a TO3 metal package, it offers high durability and effective heat dissipation, making it suitable for high-current designs. The transistor typically handles up to 15A of collector current and supports a maximum collector-emitter voltage of around 60V, depending on the manufacturer. Its DC current gain ranges roughly from 20 to 70 at moderate currents, while the transition frequency is relatively low (2.5 MHz), indicating that the 2N3055 is optimized for low-frequency power stages rather than high-speed circuits. Because of its rugged construction and predictable thermal behavior, it remains a popular choice for power supplies, audio amplifiers, motor drivers, hobbyist electronics despite the availability of more modern power transistors.
