In transistor the heat is created during transition stage means from cutoff to saturation and reverse, so if transistor used for high frequency application power loss can be minimized. The heat produced during switching is actually power loss.

What are metalloids in transistor radios used for?
The metalloids is combined in transistor radios to make them of high quality.
How do vfd's change the AC to dc current and back into AC?
Variable frequency drives use a rectifier to "chop off" the top part of the ac wave, then use capacitors to "fill in" the gaps in the voltage, making a "near dc" power. They use IGBTs, a fancy term for a high speed, high current transistor, or electronic switch, to pulse the "near dc" power out to the motor, in a pattern that appears like ac to the motor.
What is the difference between jfet and mosfet?
1-BJT is bipolar while JFET is unipolar. 2-BJT has low input impedence while JFET has high input impedence. 3-JFET has low power discipation as compared to BJT. 4-JFET has low noise as compared to BJT. 5-BJT is current controlled while JFET is voltage controlled. 6-JFET is mostly used in digital circuits.
Why class AB amplifier have high efficiency?
A class AB amplifier of the complementary transistor type has two transistors in series. Both transistors can change the resistance. If the upper transistor, a npn type, has minimum resistance and the lower transistor, a pnp type, has maximum resistance, the output voltage is near the supply voltage. One transistor is totally open and has zero current, the other transistor is totally closed and has zero voltage. Working together both transistors can set the output to any voltage between 0 and supply voltage. The class AB efficiency maximum is 100% minus the bias-power, see for example D. M. Snider, "A Theoretical Analysis and Experimental Confirmation of the Optimally Loaded and Overdriven RF Power Amplifier", 1966. Today the overdriven class AB amps are called class D.
What is the Cost of high speed steel per kg in India?
What rupees of per kg high speed steel
Is BJT used for high speed power application?
Yes
Transistor 603 12F?
a 603 12F high current power, multi-emitter transistor.
What are the advantages and disadvantages of N MOS circuits as compared to TTL?
TTL stands for Transistor-Transistor-Logic. N-MOS is a type of a metal oxide semiconductor technology. TTL is faster, but generally uses more power. MOS based devices are slower, they and they use less power. Speed is an issue when dealing with high speed data processing.
What does x denote in 74x151 ic?
It's the "family" the device belongs to. The 74151 is the original Transistor-Transistor Logic (TTL) device. The 74L151 is the low-power ("L") version. Slower than the original TTL family. Others are: S - Schottky (high-speed) LS - low-power high speed. About equivalent in speed to the original TTL, but lower power. ALS advanced low-power high-speed C - Complementary Metal-Oxide Silicon, which uses a different technology (CMOS rather than bipolar transistors), but conforms to the "74"-series logic functions. Much lower power consumption than TTL devices described above.
What is meaning of bfw11 in fet?
B=sillicon f=fet w=used in high frequency application 11=gain of transistor
What is power transistor briefly?
One capable of being used at power rating of greater than about 10 watts, and generally requiring some means of cooling
What is mean SL in SL100 transistor?
S stands for slew and L stands for low frequency... and 100 is the gain of the transistor
Where is the 1993 delta 88 high speed blower relay location?
Sorry but it is not a relay. It is a power transistor voltage regulator board located on the center area of the firewall and controlled by the Climate control computor. I have an 89 with low speed blower working only. I tapped into the module wire connection to a small switch I installed under the dash for high speed operations.
Why is a Junction transistor so named?
In a transistor a current from low resistance input circuit is transferred to a high resistance output circuit with almost unchanged magnitude. This results in a power gain. Infact the name 'transistor' is coined from 'transfer resistor'
Why is 13003 used in chargers?
It's a good high voltage power transistor designed with small SMPS in mind.
What is the difference between power electronics and digital electronics?
in digital electronics, engineers use low voltages like 5 or 12 or 24 volts but when they want to transfer electrical energy in high power which means high voltage and high ampere they use power electronics . in power electronics sometimes the transistor or diode or in power electronics language IGBT and thyristor can work in 10000 volt or higher voltages
Why the single stage common emitter transistor amplifier is famous and widely used in most of the application?
because of low cost and gain is high well amplified
