SK3157

High-voltage PNP silicon complementary Darlington power transistor designed for low-frequency power amplification and linear switching lanes. | TO-220 Plastic Package | Mid-1980s solid-state instrument amplifiers, multi-rail linear bench power supplies, industrial servo controllers. | SK3157 | NTE264 | SK3157 | 2N6051, TIP127, 2SB676, BD650, MJE6044 | Push-Pull Audio Power Output Amplifier: Paired directly with its NPN counterpart (TIP122) to build a discrete Class-AB power stage capable of driving an 8OHM studio monitor speaker box cleanly. | Pioneer and Marantz Premium Stereo Receiver Power Amps: This high-reliability PNP configuration was custom-deployed inside classic home Hi-Fi chassis to minimize crossover distortion artifacts across low-frequency audio bands.
