Selain lebih mudah dicari, harganya juga lebih terjangkau.
Bagi para pecinta audio, terutama penggemar power amplifier klasik, nama dan B778 pasti sudah tidak asing lagi. Pasangan transistor final ini sering ditemukan pada power amplifier kelas High Fidelity (Hi-Fi) dari era 90-an hingga awal 2000-an. persamaan transistor d998 b778 install
The and B778 (2SB778) are a popular pair of complementary silicon power transistors primarily used in the output stages of high-power audio amplifiers. They are designed to work together in a push-pull configuration, where the NPN-type D998 handles the positive half-cycle of the audio signal and the PNP-type B778 handles the negative half-cycle. This synergy allows them to deliver high-quality audio amplification with minimal distortion. Technical Specifications Selain lebih mudah dicari, harganya juga lebih terjangkau
: Always refer to the datasheet for the specific transistor you are using. The datasheet provides critical information on maximum ratings (e.g., voltage and current), thermal characteristics, and electrical characteristics. The and B778 (2SB778) are a popular pair
These transistors are designed for high-voltage and high-current environments, making them ideal for driving 45–50W audio systems.
