2n5088 transistor datasheet

2n5088 transistor datasheetIn this article I am giving 2n5088 transistor datasheet. It is a PNP(negative-positive-negative) bipolar junction silicon transistor which is specially designed for small signal, high speed, general purpose switching applications. It comes in TO-92 package and mostly used for small signal general purpose switching applications.

2n5088 transistor comes with three terminals named as emitter, base and collector. Emitter, base and collector are different in terms of their shape and doping concentrations. Emitter is highly doped as compared to both base and collector.

It is a current controlled device, when voltage is applied at the base terminals, it gets biased and draws current which is used to control large current at the emitter and collector side.


In this NPN transistor, base is positive with respect to emitter and voltage at the collector side is greater than the voltage at the base side.

The ability of base to control number of electrons is used for amplification purpose.

In any transistor movement of electrons plays an important role for the nature of conduction. It is a bipolar junction transistor where conduction is carried out by both charge carriers i.e. holes and electrons but majority charge carriers are electrons because it is an NPN transistor.

When small voltage is applied at the base terminals conduction is carried our between emitter and collector. Emitter emits the electrons which are then collected by collector. Base is used to control the number of electrons.

 2n5088 Pinout


This is the 2n5088 pinout and its functions. Electron reaction gets triggered when voltage is applied at the base terminals which then controls the large current at the emitter and collector side.

Circuit Diagram 2n5088 transistor datasheet


This NPN transistor comes with positive base side and negative emitter side where voltage at the base side is less than the voltage at the collector side.

It can be configured to three main configurations named as common emitter configuration, common collector configuration and common base configuration. Out of these configurations, common emitter configuration is mainly helpful for amplification purpose because it features the same voltage gain and power required for amplification purpose.

Forward current gain is an important factor, also known as amplification factor which determines the measure of current being amplified.

It is called beta, denoted by β, and is a ratio between collector current and base current.

Beta value ranges between 20 to 1000 but most the time standard value of beta is taken as 200. As it is a ratio between two currents so it has no unit.

Another important factor is the current gain which is a ratio between collector and emitter current. It is called alpha and denoted by α.

The alpha value ranges between 0.95 to 0.99 and most of the time alpha value is taken as unity.


Absolute Maximum Ratings


It should be noted that these are the are the stress ratings. If absolute maximum ratings exceed from these stress ratings, they can severely affect the quality of the device.

Similarly, if stresses are applied for extended period of time, they can badly influence the device reliability.

The value of Collector-Emitter voltage and Collector-Base voltage is 30 and 35 respectively.

Maximum power it can draw is 1.5 W.(2n5088 transistor datasheet)
