S8050 Transistor Explained / Description:

S8050 is a commonly used NPN transistor. This transistor is designed for audio amplification and wide variety of general purpose uses in electronic circuits, like switching applications. Its collector current is 1.5A or 1500mA so it can allow maximum current of 1500mA through its collector and emitter pins. Therefore we can only drive loads which are in 1500mA limit. The maximum voltage this transistor can allow through its collector and emitter pins is 20V, therefore you can only use this transistor in circuits which operate under 25V. The normal gain value of the transistor is 85 and the maximum gain value is 300. The max gain value shows the max amplification of a signal you can achieve from a transistor in an electronic circuit.


Where We Can Use it & How to Use:

S8050 transistor is a general purpose transistor, it is a perfect transistor to perform small and general tasks in electronic circuits. You can use it as a switch in electronic circuits to switch on loads under 1500mA. 1500mA is enough to handle variety of loads for example relays, LEDs, bulbs etc. It can also be used as amplifier in small amplification stages or as a separate small signal amplifier.



Class B Amplifiers

Push pull circuits

Switch for small loads

Amplifying low gain signals to high gain


How to Safely Long Run in A Circuit:

To safely run this transistor in your circuit or electronic projects do not operate this transistor from voltage higher than 25V and do not operate any load more than 1500mA or 1.5A. Use a suitable base resistor which will limits the base current to its required level. Do not expose it to heat over 150 centigrade and below -60 Centigrade.
