Persamaan Transistor D998 B778 Install

Both transistors share similar absolute maximum ratings to ensure balanced performance in a push-pull circuit: Parameter 2SD998 (NPN) 2SB778 (PNP) 120V (Min) -120V (Min) Collector Current ( ICcap I sub cap C ) 10A (Continuous) -10A (Continuous) Collector Power Dissipation ( PCcap P sub cap C ) DC Current Gain ( hFEh sub cap F cap E end-sub ) 55 – 160 55 – 160 Package Type TO-3PML / TO-3P TO-3PML / TO-3P Pinout Diagram (Front View)

Sebelum menyalakan sirkuit dengan tegangan penuh, gunakan Avo Meter untuk memastikan resistansi antar jalur normal.

If using a mica insulator, apply a very thin, even layer of thermal grease to of the mica pad. If using a modern sil-pad (silicone), thermal grease is generally not required. persamaan transistor d998 b778 install

Bagian tembaga/besi di badan transistor adalah Kolektor . Saat pemasangan, pastikan bagian ini tidak menyentuh heatsink (ground/chasis) jika tidak menggunakan mica insulator .

Rated at 100V, 25A, and 125W. Note: Check the voltage rail of your circuit, as the voltage rating is slightly lower (100V vs 120V), but current handling is superior. 3.
