Description : Justify the statement. Antiparallel diode is connected across MOSFET.
Answer :
In MOSFET current is flow from drain to source but when the load is inductive the current may flow in opposite direction. To avoid the opposite flow of current and to protect MOSFET the antiparallel diode is connected across MOSFET.
Answer :
PN junction of zener diode is heavily doped than ordinary diode. For the occurrence of Zener effect the zener diode is heavily doped. If the zener diode is not heavily doped then Zener effect ... breakdown voltage is sharp. If the diode is lightly doped the diode will have higher breakdown voltage.
