Persamaan Transistor D998 B778 Install __top__ -
If you are in a pinch, these work, but they are generally "slower" (lower fT) than the D998/B778. Cheap and easy to find.
Because they are popular, watch out for "fake" or low-quality clones. 2. The Direct Match: 2SD1047 / 2SB817 These are very close in characteristics to the originals. Specs: 140V, 12A, 100W. persamaan transistor d998 b778 install
If you cannot find the exact part numbers, you need a pair that meets or exceeds the voltage and current ratings while maintaining a similar frequency response. 1. The Upgrade Choice: 2SC5200 / 2SA1943 If you are in a pinch, these work,
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 If you cannot find the exact part numbers,
A bit more "headroom" than the D998/B778 without requiring major circuit adjustments. 3. The TIP Series: TIP35C / TIP36C
However, since these parts are older, finding original replacements can be tricky. This guide covers the best , technical specs, and essential installation tips to ensure your repair lasts. Technical Specifications: Understanding the Power
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.
