Saat melakukan perbaikan atau perakitan elektronik, komponen orisinal terkadang sulit ditemukan atau harganya terlalu mahal di pasar lokal. Artikel ini akan mengulas secara mendalam mengenai spesifikasi teknis utama, daftar persamaan yang aman, panduan pemilihan komponen pengganti, hingga tips mendeteksi komponen asli vs palsu. Spesifikasi Teknis Utama Transistor D998 dan B778 : Used in voltage regulator circuits due to
Their reputation for robust construction, high safe operating area (SOA), and excellent linearity makes them a favorite among audiophiles and repair technicians. They are designed for high-power applications, typically in
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.
Both transistors use the (Sanyo’s large, insulated power package) or sometimes TO-3P/TO-247 variants, though the classic Sanyo MT-200 is most common.
