![]() It can be used for build high power audio amplifier or in the driving stages of audio amplifier. ![]() The maximum DC current gain is upto 1000.Īs mentioned this transistor can be used wide variety of switching and amplification applications. When use as a switch the maximum load this transistor can drive is up to 10A and the maximum load voltage can be upto 100V. TIP142 and all the transistors whether they are NPN or PNP in this series are designed to use in general purpose applications such as amplification and switching. Moreover the PNP transistors in this series are TIP145, TIP146 and TIP147 these are the PNP complimentary types of TIP140, TIP141 and TIP142. But if you are driving load of 80V then you can use TIP141 and TIP142 and if the load is of 100V then you can only use TIP142 from the three. but if you are driving a load under 60V then you can use any of them. ![]() There is some little voltage and current difference between these three such as Collector–Emitter Sustaining Voltage, Collector cutoff current, collector-emitter voltage etc. The TIP142 is the transistor of the TIP14x series other NPN transistors in this series are TIP140 and TIP141. As mentioned above it is a darlington transistor which means it contains two transistors in a single package which are connected in a special way (which can be seen in the diagram in the above image) to increase the gain of the transistor many times.Īs shown in the pinout image above the first pin of the transistor is Base, second is Collector and third is Emitter. However the transistor is also manufactured in other different packages which are TO-3P and TO-247. TIP142 is an NPN darlington transistor manufactured in TO-218 or SOT-93 package. TIP142 Transistor Explained / Description: Max Storage & Operating temperature: -65 to +150 Centigrade. ![]()
