D880 Transistor In Pakistan

S8050 is an NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at the ground and will be closed (Forward biased) when a signal is provided to the base pin. It has a maximum gain value of 400; this value determines the amplification capacity of the transistor normally S8050. Since it is very high it is normally used for amplification purposes. However, at a normal operating collector current, the typical value of gain will be 110. The maximum amount of current that could flow through the Collector pin is 700mA, hence we cannot drive loads that consume more than 700mA using this transistor. To bias a transistor we have to supply current to the base pin, this current (IB) should be limited to 5mA.
