Pasangan transistor D998 (2SD998) B778 (2SB778) adalah komponen daya silikon yang sering digunakan dalam tahap penguat audio ( audio amplifier
The D998/B778 are discontinued but still available as NOS (New Old Stock) from specialized vendors. If unavailable, consider:
The D998 and B778 function as a "push-pull" pair, where the NPN (D998) handles the positive half of the signal cycle and the PNP (B778) manages the negative half. This configuration is essential for Class AB amplifiers, as it balances current flow and significantly reduces harmonic distortion. Key shared specifications include: Persamaan Transistor D998 B778
