B778 Install — Persamaan Transistor D998

Most D998/B778 setups use the heatsink as a common ground or a different voltage rail. You use a Mica insulator or a Silicone pad between the transistor and the heatsink.

Before looking for a replacement, you need to know what you are matching. The D998 and B778 are typically housed in a or TO-247 package. Type: D998 (NPN) / B778 (PNP) Collector-Emitter Voltage (Vce): 120V Collector Current (Ic): 10A Power Dissipation (Pc): 80W persamaan transistor d998 b778 install

In the world of audio power amplifiers, the and B778 (2SB778) are a legendary pair of complementary power transistors. Often found in car audio systems and home theater receivers, these NPN and PNP components work together to drive speakers with high fidelity. Most D998/B778 setups use the heatsink as a
