The first clue is a burnt board. There are many different types of transistors which complicates determining "for sure", beyond this visual observation. The absolute best way is to remove it from the circuit and test it per the specifications in the data sheet for that particular transistor.
A simple test to see if "maybe" it is good can be done by checking the base or gate voltage to emitter. This is usually .5-.7 volts in a BJT. If it is burnt out, or there is not enough voltage applied to the base, it may be burnt out. If you can open the circuit up to verify a small current is flowing from base to emitter in a BJT (in a MOSFET, there shouldn't be current flow), and verify current flow from collector to emiitter. If one of these is now an open (I.E. no current flow) you can probably assume this is a burnt out transistor.
So...the simple, sad truth is it is a lot of hassle to check this! In my opinion it is just easier to replace the transistor, assuming you can determine its' exact model number (some manufacturers scrub these, making it harder to reverse engineer things).
A Unijunction Transistor is a transistor that acts solely as a switch.
the best way is to compeair the data sheet of that transistor to the readings of that transistor. . . . .and u can get the readings of that transistor by using a fungction genrator and a c.r.o
When facing the flat side of the transistor, the Emitter - E - is on the left.
Transistor with 2 gate on top and bot of the channel
typically the amplification of a transistor 100 times.
The film transistor(TFT) is also know as Active matrix
I dont know
well either the radio control is not sending the signal or you burnt a transistor in the circuit board. that means you have to find the faulty transistor and switch it for another identical one.
You'll know if he burnt you if you saw him burn you with something really hot.
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
if they scream
burned is a verb burnt is the past tense - strange i know. e.g. : he burned down the building the building was burnt down
I know it was BELL laboratory in the fifty I believe
A silicon transistor is a transistor made of silicon.
When The Veggies Are Burnt!
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
A Unijunction Transistor is a transistor that acts solely as a switch.
