Persamaan Transistor D998 B778 __full__

). Karena keduanya dirancang sebagai pasangan komplementer (NPN dan PNP), mereka sangat ideal untuk rangkaian penguat kelas AB dengan daya keluaran yang direkomendasikan sekitar 45W hingga 50W

The and 2SB778 (PNP) are a complementary pair of power transistors widely used in audio power amplifiers , particularly in the output stages of high-fidelity (Hi-Fi) stereo systems, home theater receivers, and professional PA amplifiers. Known for their high current handling and wide Safe Operating Area (SOA), this pair has become a standard in many Japanese-brand amplifiers from the 1980s–2000s (e.g., Pioneer, Kenwood, Technics, and Sansui).

If you cannot find the original D998/B778, several equivalents offer similar or superior power handling. When replacing, it is critical to replace both (the pair) with the same model to maintain balance. 2SD718 / 2SB688 2SD718 / 2SB688 These are or high-gain single

These are or high-gain single transistors (check datasheet – most versions are single BJT, not Darlington). They require proper biasing and a heat sink.
