Used for making siren or dual Led or Lamp flasher. It can also be used in the various switching applications. This is a Bipolar PNP transistor available in metal can package, having a high value of current mA with low voltage of 40v. If supply is provided to the base pin it stops conducting current between emitter and collector and said to be in OFF state.

Can be used in Darlington Pair. Submitted by webmaster on 5 December It can also amplifies the power and current.


When use as a amplifier, can be operated in the active region. For finding the value of that resistor you can use the formula: Applications Where amplification of low power is needed we use this transistor. As it is used for the amplification and switching.

TL — Programmable Reference Voltage. If we provide ground to the base pin then the transistor will be in reverse biased and said to be turn ON.

Amplification factor usually determined in term of power, for calculating the current gain we use the formula: For finding the value of that resistor you can ratasheet the formula:. The transistor is having DC current gain value of to which shows the amplification capacity of the transistor. When use as a switch, can be operated in saturation region and cut-off region.

The condition of being forward biased is datasheeh 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. For the protection of transistor a resistance added in series with it.

So, from that you can find the value of resistance to be added in series with it. Amplification factor usually determined in term of power, for calculating the current gain we use the formula:. 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. Where, the value of V BE will be 5v for this transistor.

There are three configuration used in an amplifier circuit are common emitter, common base, common collector.

Pin configuration Pin No. The maximum value of providing base current is mA. This transistor is used where low power amplification is needed.
