DATASHEET 2N2907A PDF

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 use as a amplifier, can be operated in the active region. Pin configuration Pin No. Where, the value of V BE will be 5v for this transistor. So, from that you can find the value of resistance to be added in series with it.

If supply is provided to the base pin it stops conducting current between emitter and collector and said to be in OFF state. Submitted by webmaster on 5 2na 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 maximum value of providing base current is mA. This is a Bipolar PNP transistor available in metal can package, having a high value of current mA with low voltage of 40v. It can also be used in the various switching applications.

It can also amplifies the power and current. Amplification factor usually determined in term of power, for calculating the current gain we use the formula:. Used for making siren or dual Led or Lamp flasher. The transistor is having DC current gain value of to which shows the amplification capacity of the transistor. 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. There are three configuration used in an amplifier circuit are common emitter, common base, common collector. When use as a switch, can be operated in saturation region and cut-off region. 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. This transistor is used where low power amplification is needed. Amplification factor usually determined in term of power, for calculating the datashet gain we use the formula: Can be used in Darlington Pair.
