Persamaan Transistor D998 — B778 Install

| Transistor Asli | Persamaan Terbaik | Level Kesulitan Install | Resiko Panas | | :--- | :--- | :--- | :--- | | | 2SC5200 | Mudah (plug and play) | Rendah | | B778 (PNP) | 2SA1943 | Mudah | Rendah | | D998 (NPN) | NJW0281 | Sedang (butuh re-bias halus) | Sangat Rendah | | D998 (NPN) | TIP41C (Darurat) | Sulit (arus drop) | Tinggi |

Untuk performa audio optimal, matching gain sangat penting. Idealnya, nilai (penguatan arus DC) antara transistor NPN dan PNP dalam satu channel harus sedekat mungkin.

Persamaan Sanken yang memiliki kualitas baik. 2. Persamaan Berdasarkan Karakteristik: TIP35C / TIP36C (Package TO-247) 2SC5198 / 2SA1941 persamaan transistor d998 b778 install

Artikel ini akan membahas secara mendalam spesifikasi utama dari pasangan D998 dan B778, daftar komponen pengganti (persamaan) yang aman, urutan kaki (pinout), hingga langkah-langkah installasi yang benar pada pendingin (heatsink). Spesifikasi Utama Transistor D998 & B778

Use a multimeter in "Diode Mode" to check for shorts between the Collector and the Heatsink. Go to product viewer dialog for this item. | Transistor Asli | Persamaan Terbaik | Level

Dihubungkan ke output driver (jalur basis) melalui resistor (biasanya 10 Ohm). Kaki 2 (Kolektor):

Use a multimeter in continuity/resistance mode to verify insulation. Measure the resistance between the metal tab/center pin of the transistor and the bare metal of the heatsink. It must read as an open circuit (infinity). If there is continuity, remove it and check for an insulation puncture. Step 4: Soldering and Final Testing Go to product viewer dialog for this item

Check for at the speaker terminals (it should be near 0V).

merupakan pasangan transistor daya ( power transistors ) komplementer yang sangat populer digunakan pada sistem penguat suara ( audio amplifier ) seperti power audio mobil, home theater , dan speaker aktif. Transistor D998 (2SD998) bertipe NPN, sedangkan pasangannya, B778 (2SB778) , bertipe PNP.
