Using the mraa library is the direct way to work with the GPIO lines and you have to master it.
PN2222 TRANSISTOR THRESHOLD HOW TO
It is worth the effort and in this chapter we show you how to set up the IDE and get coding. It is fast, almost as easy as the other languages and gives you direct access to everything. You can program the Edison in Python, JavaScript or C/C+ but there are big advantages in choosing C. This chapter explains how to set up the Edison for both configurations. When you are prototyping with the Edison you are going to need to use one of the two main breakout boards - the Arduino or the mini. If you have ever wondered if you need an Edison or an Arduino or even a Raspberry Pi then this is the place to start.
PN2222 TRANSISTOR THRESHOLD DOWNLOAD
To Download the datasheet just copy and paste the below link in your browser.In this chapter we consider the Edison's pros and cons and get an overview of its structure and the ways in which you can make use of it.
Max collector current is 600mA therefore do not drive load of more than 480mA.To get better performance do not use the transistor to its absolute maximum ratings and always stay 20% below from its max ratings.Safe Operating Guidelines / Absolute Maximum Ratings:įollow these safe operating guidelines to properly operate the transistor in your circuits: The using procedure of the transistor is same as we use any other BJT transistors.Īny type of electronic signal amplification Moreover due its higher transition frequency it can also be used in RF circuits. Other than that it can also be used for amplification purposes. When used as a switch it can drive load of up to 600mA which is quite enough to drive wide variety of loads in electronic circuits such as multiple high power LEDs, high current relays, motors, high power transistors etc.ĢN2222 (Metal Case) is not the exact match of the PN2222 but can be used interchangeably, and there are also some advantages of using the metal case for example it has high collector current of upto 800mA, higher operating temperature and higher collector to emitter voltage but if your load requirements are less then 600mA then PN2222 can be a good choice.įirst of all PN2222 is primarily designed for general purpose uses due to which it can be used for variety of general applications and can also be used as a replacement of other general purpose transistors.Īdditionally It can be used to drive any type of load that falls under 600mA. Looking at the other specs the max collector to emitter voltage is 30V, transition frequency is 250MHz, minimum and maximum DC current gain is 30 to 300 and max collector dissipation is 625 Milliwatt.Īs mentioned it can be used for general purpose switching and amplification purposes. The maximum collector current of the transistor is 600mA, which is quite unique because mostly available TO-92 package transistors have 100mA to 200mA max collector current capability. The transistor is packed with quite good specs in its TO-92 package and low cost which makes it a reliable choice for wide variety of commercial and educational uses. It is a general purpose transistor and can be used in wide variety of switching and amplification applications. PN2222 is a popular transistor NPN bipolar junction transistor (BJT) available in TO-92 package. PN2222 Transistor Explained / Description: Max Storage, Operating & Junction temperature range: -55 to 150 Centigrade.Minimum & Maximum DC Current Gain (hFE): 30 to 300.Max Collector Dissipation (Pc): 625 Milliwatt.
Max Collector-Emitter Voltage (VCE): 30V.
