The common-emitter current gain stands from 15 to 75 which is the capacity of the transistor it can amplify the small input current.The junction temperature ranges from -65 to 150C and the transition frequency is 3MHz which is a measure of the transistor’s high frequency operating characteristics.This PNP transistor comes in TO-220 package with collector current 6A which demonstrates it can support the loads under 6A.Which is the opposite in the case of NPN transistor where electrons are the majority carriers and holes are minority carriers. Both electrons and holes are used for the conductivity, however, holes are the majority carriers and electrons are the minority carriers. The Tip42c is a bipolar transistor which means two charge carriers are used for the conduction process inside the transistor.Don't apply these ratings for more than the desired time, else they will influence the device reliability. These are the main features and the power ratings of the transistor Tip42c. Common-emitter current gain = hfe: 15 to 75.Operating Junction Temperature = Ti: -65 to 150 ☌.The following are the main features of device Tip42c Its value is always less than 1, commonly lies from 0.90 to 0.95 but more often than not its value is taken as unity. One is a common-emitter current gain which ranges from 15 to 75 in this case and common-base current gain which is a ratio between collector current to emitter current, this is normally called alpha. Two current-gains are important while studying bipolar transistors.As this bipolar transistor controls the small current to produce large current, the reason bipolar transistors are considered as a current-controlled device in contrast to FETs(field effect transistor) which is a unipolar transistor (conductivity happens due to one charge carrier) that are voltage-controlled devices.

The two p-doped layers surround the n-doped layer. The n-doped layer represents the base terminal where negative voltage is applied to start the transistor action. Tip42c contains three layers where two are p-doped silicon layers and one is an n-doped silicon layer.The small input current across one pair of terminals is used to generate large output current across other pairs of terminals.These pins are also known as transistor terminals that are connected with the external electrical circuit. It comes with three pins called the emitter, base, and collector.It is composed of silicon material and comes in the TO-220 package.Tip42c is a PNP medium power bipolar transistor mainly used for switching and amplification purpose.Just bear with me for a little while as I’ll be documenting the main features, pinout, applications, and datasheet of this tiny component Tip42c. The 6A is collector current which indicates the value of loads this transistor can support. The 5V is the voltage across base and emitter terminals which projects the value of voltage required to bias this transistor. The voltage across collector and emitter terminals is 100V and the voltage across base and collector terminals is 100V. It is made up of silicon material and falls under the category of PNP transistors. Tip42c is a medium power transistor mainly used for amplification and switching purpose. In this post, I’ll detail the Introduction to Tip42c.
