Persamaan Transistor D998 B778

For audio quality, buy matched pairs or measure hFE. Original parts had hFE range 40–140. Modern equivalents (e.g., 2SC5200) are typically 55–160. Close matching between NPN and PNP reduces distortion.

They are commonly found in high-fidelity (Hi-Fi) stereo amplifiers, PA systems, and high-end car audio amplifiers from the 1990s–2000s (e.g., brands like Technics, Kenwood, JVC, Pioneer). Persamaan Transistor D998 B778

The h FE linearity from 0.5A to 10A is excellent for this type, minimizing crossover distortion. The f T of 15-20 MHz is ideal for audio (20Hz-20kHz), providing enough gain bandwidth for stability without risking parasitic RF oscillations when properly laid out.
