Persamaan Transistor D998 B778: Install

D998 (2SD998) B778 (2SB778) are a popular pair of complementary silicon power transistors widely used in the output stages of audio power amplifiers. They are typically found in Class AB push-pull configurations to deliver balanced power to speakers. Technical Specifications

What is a Transistor?

Verify Polarity: Double-check which is NPN (D998) and which is PNP (B778). Swapping them will damage the circuit. persamaan transistor d998 b778 install

• Orientasi: D998 (NPN) biasanya dipasang di sisi VCC (+). B778 (PNP) dipasang di sisi VEE (-). Jangan tertukar posisi pada board.
• Soket vs Solder: Untuk transistor final, sangat disarankan untuk langsung menyolder kaki ke PCB daripada menggunakan soket, karena arus besar (10A) akan melelehkan soket murah dan menyebabkan resistansi tinggi.
