Product Description
The BC557 transistor is a general‑purpose PNP bipolar junction transistor (BJT) designed for low‑current amplification and switching applications. Packaged in a compact TO‑92 case, it is widely used in audio circuits, complementary push‑pull stages, and signal processing. With a maximum collector current of 100 mA and voltage rating up to 45 V, the BC557 is ideal for small load control and low‑noise amplification. Its complementary nature to the BC547 makes it perfect for paired designs in educational, DIY, and professional electronics projects.
