Brief Description This is a Bipolar PNP transistor available in metal can package, having a high value of current mA with low voltage of 40v.
The condition of being forward biased is when the base connected to the ground or having no supply on it, and as a signal is provided to base pin it goes reverse biased.
The transistor is having DC current gain value of to which shows the amplification capacity of the transistor. As it is used for the amplification and switching. When the transistor is fully biased it allows a maximum of mA current through the collector and provide a voltage collector to emitter of 1. If we provide ground to the base pin then the transistor will be in reverse biased and said to be turn ON. If supply is provided to the base pin it stops conducting current between emitter and collector and said to be in OFF state.
For the protection of transistor a resistance added in series with it. The maximum value of providing base current is mA. So, from that you can find the value of resistance to be added in series with it. There are three configuration used in an amplifier circuit are common emitter, common base, common collector. This transistor is used where low power amplification is needed.
It can also amplifies the power and current. Where amplification of low power is needed we use this transistor. It can also be used in the various switching applications. Used for making siren or dual Led or Lamp flasher. Can be used in Darlington Pair. Component Datasheet.
