Both transistors are housed in a or TO-3PF package, known for excellent heat dissipation during prolonged use. 2SD998 (NPN) 2SB778 (PNP) Polarity Collector-Emitter Voltage ( VCEOcap V sub cap C cap E cap O end-sub ) Collector Current ( ICcap I sub cap C ) Power Dissipation ( PCcap P sub cap C ) Current Gain ( hFEh sub cap F cap E end-sub ) 55 – 160 55 – 160 Persamaan (Equivalents & Substitutes) Apply a thin layer of heat sink compound

Saya membalik papan PCB (Printed Circuit Board). Dengan hati-hati, saya mencoba melepas sisa-sisa transistor yang rusak menggunakan solder sucker . Setelah bersih, saya menelusuri jalur PCB dengan AVO meter. persamaan transistor d998 b778 install

Apply a thin layer of heat sink compound to both sides of the insulator for better heat transfer.
