SS8550 PNP Bipolar Transistor – 3 Pieces

The SS8550 is a general-purpose PNP bipolar junction transistor designed for medium-current switching and amplification applications. Manufactured by Changjiang Electronics, it supports a maximum collector current of 1.5A and a collector-emitter voltage of 25V, making it suitable for driver stages, audio amplifiers, power control circuits, and medium-load switching. With stable DC gain, low saturation voltage, and reliable thermal performance, the SS8550 is widely used in embedded electronics, battery-powered circuits, and complementary transistor designs alongside NPN types like S8050.
