The devices are manufactured in planar technology with “base island” layout and are
suitable for audio, power linear and switching applications.

The 2N3055 was designed for medium-current and high-power circuits. Commercially, it was used in many linear power supplies, audio amplifiers and low frequency power converters. It was second sourced by other manufacturers; Texas Instruments listed a single-diffused mesa version of the device in an August 1967 datasheet.One limitation was that its frequency response was rather low (typically the unity-gain frequency was 1 MHz).
