This table show differences between BC547 and 2N2222ĢN2222 is used in a variety of electronic projects due to its excellent features like a larger collector current 600mA. Other differences between both transistors are given below: Spec This affects the circuit while operating at a higher frequency. The input and output capacitance of 2N222 is slightly higher than BC547. Are there any differences between 2N2222 and BC547 Transistor?īetween BC547 & 2N2222, there are minor changes in output and input capacitance. For most projects, they are used to turn on a load that would kill the I/O pin of a microcontroller or microprocessor. In digital circuits, they switch on and off while in analog circuits they are used to amplify signals. Although using an equivalent transistor requires a detailed comparison, the BC547 is still a good alternative to 2N2222. Transistors are one of the most versatile discrete components in electronics. BC547 transistor is considered the best equivalent of 2N2222 & can work well in your projects. Given below is the list of transistors that are equivalent to 2N2222 and can be used as a replacement. Which transistors are equivalent to 2N2222? The 2N2222A transistor is a common NPN BJT & it is mainly used in the applications of switching & amplifying with less power. Therefore, it is important to refer to the datasheet for the exact part number and manufacturer. P2N2222A Amplifier Transistors P2N2222A Amplifier Transistors NPN Silicon Features These are PbFree Devices MAXIMUM RATINGS (TA 25C unless otherwise noted) THERMAL CHARACTERISTICS Stresses exceeding Maximum Ratings may damage the device. The exact specifications depend on the manufacturer, case type, and variation. This table shows the technical specifications of the 2N2222 Transistor AC analysis linearizes the circuit about the operating point and plots the small. to the limit above the f3dB in this circuit is sensitive to several stongly varaiable transistor properties and >4x variation wouldnt be unexpected a 160 MHz f3dB must be a mistaken sim Spice. The technical specifications of 2N2222 in TO-18 metal packaging and 2N2222A transistor in TO-92 packaging are given below: Spec Datasheets for 2n2222/2n2222a report Ft of 250Mhz or 300Mhz. This can damage the transistor, to prevent this, we use a diode which diverts the. Diode in circuit: It is possible, when motor is spinning, suddenly turn off because the magnetic field inside it collapses, generating a voltage spike. The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V and 75V, 40V, 6V respectively.Īlso, the 2N2222 comes in metal packaging whereas the 2N2222A is available in TO-92 plastic enclosure only.ĢN2222A is a better option considering its higher ratings, low cost, and TO-92 packaging. The connections are easy, see the image above with the breadboard circuit schematic. The emitter is denoted by ‘ E’.ĢN2222 VS 2N2222A: What’s the difference?īoth are similar types of transistors but the 2N2222A has higher Maximum absolute ratings than 2N2222. This pin act as an outlet and the current comes out of the transistor from here. This pin controls the transistor biasing. This pin act as an inlet as the current enters the transistor from here. Original 2N2222 Pinout(TO-18 Package) Pin The 2N2222 is a popular NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications.
