...is constant, i. e.,. Basic Theory—Variable Resistance. A PIN diode is essentially a variable resistor. To determine the value. dQS = 0, so that. of this resistance, consider a volume comparable to a typical PIN. dt. Q. diode chip, say 20 mil diameter and 2 mils thick. This chip has a. I. S. F. = Idc =. T...

1/2w ,1w , 5w,10w,and 50 watt. Go to Top. Why is the semiconductor device called a tunnel diode?. With a standard germanium diode a potential barrier of 0.3 volts must be exceeded before the diode can conduct. However in a tunnel diode, according to quantum theory, a particle, in a highly doped diode...

...blue-violet laser diode source with a long coherence length and some level of wavelength tuning. Prior approaches, such as external cavities with diffraction gratings [1], have been used to generate single longitudinal mode tunable lasers near 405 nm. Such cavities require a very low reflectivity...
