D882 Datasheet
D882 datasheet
D882 can be used for a wide variety of switching and amplification purposes. It is packed with some very interesting features, the max collector current is 3A which is enough to drive many relays, LEDs, Bulbs, motors, some part of an electronic circuit, etc. the minimum collector saturation voltage is only 0.3V.
What is the equivalent of D882 transistor?
The equivalent for D882: TIP31. BD679. BD136.
What is NEC D882?

What is the use of B772 transistor?
B772 is a medium power bipolar junction transistor mainly used for switching and amplification purpose and belongs to the PNP transistor family. It comes in the TO-126 package and carries a collector current of 3A which means it can support load under 3A.
What are the 3 function of transistors?
transistor, semiconductor device for amplifying, controlling, and generating electrical signals.
What are the 3 leads of a transistor?
Transistors are manufactured in different shapes but they have three leads (legs). The BASE - which is the lead responsible for activating the transistor. The COLLECTOR - which is the positive lead. The EMITTER - which is the negative lead.
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.
Can I use a transistor as a relay?
The transistor here is serving the same function as the relay. However, it can switch much faster than the relay. In addition, because there are no mechanical parts, it will reliably function for more switching operations than the relay. However, current can only flow in one direction through a transistor.
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.
What is the most powerful transistor?
As of 2022, the highest transistor count GPU is Nvidia's H100, built on TSMC's N4 process and totalling 80 billion MOSFETs.
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.
What are the 2 purposes of a transistor?
Transistors are also used for low-frequency, high-power applications, such as power-supply inverters that convert alternating current into direct current. Additionally, transistors are used in high-frequency applications, such as the oscillator circuits used to generate radio signals.
What are the 2 types of transistor?
Transistors typically fall into two main types depending on their construction. These two types are bipolar junction transistors (BJT) and Field Effect Transistors (FET).
What are the two types of voltage?
Voltage is either alternating current (ac) voltage or direct current (dc) voltage.
Why is called transistor?
The word transistor is a combination of transfer and resistance. This is because it transfers the resistance from one end of the device to the other end or we can say, transfer of resistance. Hence, the name transistor. Transistors have very high input resistance and very low output resistance.
Why does a transistor have 3 legs?
The transistor has three legs, these are the base, collector and the emitter. The emitter is always connected to 0v and the electronics that is to be switch on is connected between the collector and the positive power supply. The base of the transistor is used to switch current through the collector and emitter.
Why does a transistor have 3 pins?
Most discrete transistors have 3 terminals representing base, collector and emitter for a bipolar junction transistor (BJT) or gate, drain and source for a field effect transistor (FET) or Metal Oxide (Silicon) FET (MOSFET), hence 3 legs or for some power devices a 'can' which serves as the heatsink mounting (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.
What can I replace a resistor with?
Replace the resistor with a fuse. We can calculate the appropriate current (230 V at 15 ~ 16 A) and have it soldered. This is an even better option since in the worst case it will blow and I will save other components.
Can I use capacitor instead of resistor?
No. Capacitors have a frequency dependent impedance and the magnitude of that impedance is expressed in ohms. But that does not make them a resistor. Not in any way….
