Transistor 2SD998 (D998) and 2SB778 (B778) are complementary power transistors frequently used in the output stages of audio amplifiers. They are designed for high-power applications, typically in the 45–50W range. Core Specifications These transistors are almost always used as a matched pair: High-power silicon transistor. 2SB778 (PNP): Complementary partner to the D998. Voltage ( VCEOcap V sub cap C cap E cap O end-sub ): 120V. Current ( ICcap I sub cap C ): 10A. Power Dissipation ( PCcap P sub cap C ): 80W to 100W, depending on the manufacturer.
Salah. Transistor tegangan tinggi (Vceo 200V+) biasanya memiliki gain rendah di arus tinggi (Ic >5A). Ini menyebabkan suara clipping keras. Untuk tegangan simetris amplifier antara 45V hingga 65V DC, Vceo 120V - 160V sudah ideal.
