Equivalent transistors often have higher power ratings (e.g., 150W–230W vs 100W). This is safe, but ensure the mica insulator and thermal paste are properly applied.
Most D998 and B778 transistors use the package with the following pinout (looking at the front face): Persamaan Transistor D998 B778
For optimal performance in push-pull output stages, the D998 and B778 are : Equivalent transistors often have higher power ratings (e
