If original D998/B778 are unavailable, use these complementary pairs (verify pinouts and hFE):

With a maximum power dissipation of (at case temp 25°C), a large heatsink is mandatory. For stereo 100W/channel amplifiers: Persamaan Transistor D998 B778

These transistors were widely used in older audio equipment (stereo amplifiers, receivers) and are now often found in electronics repair scenarios. While they are robust, they are considered "legacy" components, meaning modern equivalents are often used for replacements.

Sepasang transistor ini (2SD998 dan 2SB778) dirancang khusus untuk panggung output penguat audio ( audio amplifier final stage ) berdaya menengah, seperti pada sistem audio mobil (car amplifier) dan penguat daya rumahan berefisiensi tinggi.

The D998 and B778 are typically utilized as a in Class B or Class AB push-pull amplifier configurations. These transistors can handle moderate voltage (up to

: Employed in DC motor driver circuits where high current (up to 10A) is required. Purchasing Information This pair is widely available from retailers such as . Prices typically range from

Note: Do not confuse with TO-247 or TO-3P. MT-200 has wider body and different pin shape.

: Karena bagian belakang bodi transistor (tab metal/kolektor) menghantarkan listrik, gunakan isolator mika atau lembaran silikon saat memasangnya kembali ke heatsink aluminium. Pastikan juga sekrup pengencang diberi cincin isolator plastik ( bushing ). The D998 and B778 are typically utilized as

yang dari komponen aslinya. Jangan pernah menggunakan komponen pengganti dengan spesifikasi yang lebih rendah karena akan memicu kerusakan fatal pada sirkuit.
