push({});Where We Can Use it How to Use:S8550 is a general purpose transistor therefore you can use it at the output of your audio amplifier circuits to amplify the output audio signal to 1 watt.and do not use it in the temperature above 150 centigrade and below -65 centigrade.

therefore it is a must to have transistor in your electronics lab.mp3 audio amplifiers and in the output of buzzer circuits etc.
