Persamaan Transistor D998 B778 ^new^ -

The (NPN) and 2SB778 (PNP) are a complementary high-power transistor pair developed primarily for audio power amplifier output stages . Manufactured by Sanyo (now part of ON Semiconductor), these devices were widely used in high-fidelity (Hi-Fi) stereo amplifiers, public address systems, and industrial power drivers during the late 1980s through the 2000s.

Transistor dengan kode (nama lengkap: 2SD998 ) adalah tipe NPN , sedangkan B778 (nama lengkap: 2SB778 ) adalah tipe PNP . Keduanya dirancang untuk bekerja secara berpasangan ( matched pair ) dalam sistem penguat sinyal Push-Pull Class AB .

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

Jika hanya salah satu yang rusak (misal D998 putus, B778 masih bagus), Anda bisa mengganti satu sisi saja dengan pasangan yang masih berkeluarga.

In the realm of power electronics, complementary transistor pairs are essential for efficient power amplification. The and 2SB778 are silicon epitaxial planar transistors designed for high-power applications. They are widely used in audio frequency (AF) output stages and general-purpose switching.

(tergantung produsen). Hanya gunakan opsi ini jika tegangan suplai ( Vcccap V sub c c end-sub ) power amplifier Anda di bawah 2. Persamaan Upgrade (High Performance) | Ciri | Original Sanyo | Palsu (Aspal)

For any medium-to-high power analog application requiring ±140V and 15A, the D998/B778—or its modern equivalent—remains a solid engineering choice.
