Persamaan Transistor D998 B778 💯

| NPN Equivalent | PNP Equivalent | Notes | | :--- | :--- | :--- | | | TIP36C | Only if voltage is ≤100V (Vceo=100V). Not a perfect match but works in low-voltage amps. 125W, 25A. | | 2N3055 | MJ2955 | Very old; 60V only. Not recommended unless amplifier is low-voltage (<±35V supply). |

| Parameter | 2SD998 (NPN) | 2SB778 (PNP) | | :--- | :--- | :--- | | | 180 V | 180 V | | Collector-Emitter Voltage (Vceo) | 160 V | 160 V | | Emitter-Base Voltage (Vebo) | 5 V | 5 V | | Collector Current (Ic) | 12 A (15 A peak) | 12 A (15 A peak) | | Power Dissipation (Pc) | 100 W | 100 W | | DC Current Gain (hFE) | 40 – 140 | 40 – 140 | | Transition Frequency (ft) | 25 MHz | 25 MHz | | Package | TO-3P (or TO-247) | TO-3P (or TO-247) | Persamaan Transistor D998 B778

If you cannot find the exact D998/B778 pair, you can consider these substitutes, but always verify the pinout and physical package size (TO-3P/TO-3PF) before installation: Transistor D998 - Mercado Libre | NPN Equivalent | PNP Equivalent | Notes

Oleh karena itu, menggunakan dari merek ternama seperti Toshiba, Sanken, atau Fairchild adalah solusi paling rasional. | | 2N3055 | MJ2955 | Very old; 60V only
