### Brief Description

2N5088 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N5088 has a gain value of 900 (normally), maximum it reaches up to 1200. This value determines the amplification capacity, which is high in this transistor.

### How to Use 2N5088 Transistor in a Circuit?

This transistor like all can be used either as a switch or as an amplifier. The Base-Emitter voltage of this transistor is 3V so you just have to supply this voltage across the base and emitter of the transistor to induce a base current into the transistor. This transistor will make it forward biased and thus closes the connection between collector and emitter. However one important thing to notice is the Base resistor a.k.a current limiting resistor. As the name suggests this resistor will limit the current flowing through the transistor to prevent it from damaging. The value for this resistor can be calculated using the formula

`RB = VBE / IB`

To make things simple we have shown a simplified circuit to make a transistor as switch. In actual circuit modifications might be required. I have used a base voltage of 5V and a value of 1K as current limiting resistor
