How do you know if a transistor is working?
Connect the base terminal of the transistor to the terminal marked positive (usually coloured red) on the multimeter.
Connect the terminal marked negative or common (usually coloured black) to the collector and measure the resistance.
It should read open circuit (there should be a deflection for a PNP transistor)..
Does water permanently damage electronics?
Pure water will not destroy electronic devices, neither when the device is on nor when it is off. You could technically submerge your device in pure water and it won’t destroy it. Pure water is a very poor conductor, so it won’t affect your electronic devices very much if at all.
Can you fix water damaged electronics?
Once the device is thoroughly dry, it is safe to attempt to replace the battery or power it on. Technology damaged by water offers no guaranteed fix, especially if corrosion has set in. … If your electronics were completely submerged in water, the internal circuitry is likely to be beyond repair.
What can damage electronics?
Electronic components have a wide range of failure modes. These can be classified in various ways, such as by time or cause. Failures can be caused by excess temperature, excess current or voltage, ionizing radiation, mechanical shock, stress or impact, and many other causes.
How do I know if a transistor is bad?
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 are the 2 types of semiconductor devices?

What semiconductors are used for?
Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits. Such devices have found wide application because of their compactness, reliability, power efficiency, and low cost.
What is the most basic semiconductor device?
The most common semiconductor device in the world is the MOSFET (metal–oxide–semiconductor field-effect transistor), also called the MOS transistor. As of 2013, billions of MOS transistors are manufactured every day.
How can you confirm a transistor as defective?
How to Know if a Transistor Defective – PNPGet a DMM and set it to diode mode.Connect the positive probe of the DMM to the base or the “P” or the emitter of the above figure for the PNP type. … Transfer the positive probe of the DMM to the other “P” or the collector pin.More items…•Jun 12, 2019
Do electronics go bad in storage?
If you store your electronics right, they should survive in storage for years. However, it always pays to be prepared for the worst case. After all, electronic devices are not designed to sit unused and without power for days, weeks and months on end.
Can Electronics last forever?
All electronic devices contain semiconductors. … This is the main reason electronics can’t last “forever”. It’s what usually strikes first if the device isn’t damaged.
Do electronics wear out?
Unlike mechanical parts, electrical components generally do not wear out per se. Discrete analog component parameters tend to drift over time and can cause problems with sensitive designs. Integrated circuits can undergo electromigration.
How long do electronic devices last?
Initially expected to last 40+ years, the average lifespan of electronics today ranges from 1.5 to 13 years, with the majority averaging 4-5 years.
What are the 2 types of semiconductor?
Semiconductors are materials that have properties of both normal conductors and insulators. Semiconductors fall into two broad categories: Intrinsic semiconductors are composed of only one kind of material; silicon and germanium are two examples. These are also called “undoped semiconductors” or “i-type semiconductors.
What causes transistors to fail?
Simple short answer is that solid state components don’t like heat. If a transistor starts drawing too much current, then heat is the result and the junction can fail.
How do you kill electronic devices?
the classic method to destroy a piece of solid-state electronics is with an electromagnetic pulse (EMP), as is generated by the explosion of an atomic or nuclear bomb, or a device called a disruptor- which is used by police to disable an explosive device with an electronic timer in it.

What is failure analysis semiconductor?
Semiconductor Failure analysis (FA) is the process of determining how or why a semiconductor device has failed, often performed as a series of steps known as FA techniques. … Failure analysis is necessary in order to understand what caused the failure and how it can be prevented in the future.
