SS8550 PNP Bipolar Transistor – 3 Pieces

The Changjiang SS8550 is a general-purpose PNP bipolar junction transistor designed for medium-current switching and amplification applications. It supports a maximum collector-emitter voltage of 25 V and a continuous collector current of 1.5 A, making it suitable for driver stages, audio amplification, and power control circuits. The device provides stable DC current gain and reliable thermal performance for low- to medium-power designs. It is supplied in a TO-92 through-hole package and operates over a temperature range of –55 °C to +150 °C.
