PPT-Zener diode Z ener diode

is a special type of device designed to operate in the zener breakdown region reverse breakdown region The breakdown voltage of a zener diode is carefully set by controlling the doping level during manufacture . The resistance value of the PIN diode is determined only by the forward biased dc current In switch and attenuator applications the PIN diode should ideally control the RF signal level without introducing distortion which might change the shape of t Course .
