Pn2222a pinout

PN2222A Overview It is an NPN type transistor with an operating temperature range of -55 to 150 degrees Celsius. The component can dissipate 625 mW of power, giving it good thermal control for not being a MOSFET, which is designed for thermal dissipation.

Is PN2222 and 2N2222 the same?

PN2222 and 2N2222 are both NPN bipolar junction transistors, and they are interchangeable under most circumstances.

How much current can a PN2222 handle?

This device is for use as a medium power amplifier and switch requiring collector currents up to 500mA.

Can I use BC547 instead of 2N2222?

The BC547 and 2N2222 transistors are both bipolar NPN transistors. The 2N2222 and BC547 transistors are both general-purpose transistors that are frequently used in electrical circuits; the BC547 transistor is one of the best transistor equivalents for the 2N2222 transistor.

What are the 3 terminals pins of a transistor?

A transistor is an electronic device that contains three terminals named emitter, base, and collector.

What are the 3 pins of a transistor called?

In general, all transistors have three pins: base, collector, and emitter. Transistor is a bi-polar device that is a transistor with two junctions namely BE and CE DE EE FE.

Can I use C945 instead of 2N2222?

As far as specs are concerned the C945 has more gain, Hfe, than the 2N2222, but for most applications yes you could use C945 in place of the 2N2222. One issue though is C945 has different pin out than the 2N2222. The 2N2222 base has pin out of emitter-base-collector (base is center pin).

Can I use BC548 instead of 2N2222?

They are the same and are used interchangeably most of the time. 2N2222 is a metallic package TO-18 and PN2222 is a plastic package TO-92, you can refer to the datasheet of them. Can I use BC548 instead of BC547? NO, BC547 is an NPN and BC548 is a PNP transistor both the transistors are not substituted for each other.

Can I use 2N3904 instead of 2N2222?

The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. For most circuits, a 2N3904 would suffice, however, if you need more above 200mA, a 2N2222 should be used instead.

Why 2N2222 transistor is used?

The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture.

How fast can a 2N2222 switch?

The 2N2222 has a combined rise-time, fall-time, and storage-time of 310ns, thus the maximum switching frequency is about 3MHz so it's not appropriate for this application.

What is a PN2222 transistor used for?

The PN2222 is a conjoint NPN bipolar junction transistor which is used for common persistence less power intensifying or swapping circuits applications. It is intended for low to intermediate current, squat power, intermediate voltage and can activate at a temperately higher speed.

Why BC547 transistor is used?

BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.

Can you use a transistor without a resistor?

A transistor without a resistor on the base is like an LED with no current-limiting resistor. Recall that, in a way, a transistor is just a pair of interconnected diodes. We're forward-biasing the base-emitter diode to turn the load on. The diode only needs 0.6V to turn on, more voltage than that means more current.

What the difference between a BC547 and an 2N2222 transistor?

The 2N2222 has an emitter, base, and collector pinout, whereas the BC547 has a collector, base, and emitter pinout. The collector to base voltage at 2N2222 is 60 volts, whereas it is 50 volts at BC547, and the collector to emitter voltage is 30 volts at 2N2222 vs 45 volts at BC547.

How do I find the pinout of a transistor?

Pin Identification of Transistors In plastic casing, one side of the transistor is Flat which is the front side and the pins are arranged serially. To identify the pins, keep the front flat side facing you and count the pins as one, two etc. In most NPN transistors it will be 1 (Collector), 2 (Base) and 3 ( Emitter ).

How do you test a 3 pin transistor?

Hook the positive lead from the multimeter to the to the EMITTER (E) of the transistor. Hook the negative meter lead to the BASE (B) of the transistor. For an good NPN transistor, you should see “OL” (Over Limit). If you are testing PNP transistor, the meter should show a voltage drop between 0.45V and 0.9V.

How do you identify the terminal of a transistor?

The first step in the transistor test is to identify the terminals (Base, Emitter & Collector) of the transistor. ... Terminal's Identification

Put Multimeter in diode test mode.
Place black (common) probe & red probe on any two terminals at a time.
Test all possible terminal combinations i.e. 1-2, 1-3, 2-1, 2-3, 3-1, 3-2.

How do you know if a transistor is NPN or PNP?

The schematic symbols for NPN and PNP transistors are extremely similar. The sole distinction is the orientation of the arrow on the emitter. It points outward in an NPN (on the left) and inward in a PNP (on the right).
