1.	As the voltage on the drain is increased, a value is reached at which the pn junction between the drain region and substrate suffers avalanche breakdown known as(a) Weak avalanche(b) Strong avalanche(c) Weak storm(d) Punch-throughI have been asked this question in unit test.This interesting question is from The Body Effect topic in chapter MOS Field Effect Transistors (MOSFETs) of Electronic Devices & Circuits
Answer» Correct choice is (a) Weak avalanche The explanation: As the VOLTAGE on the drain is INCREASED, a value is REACHED at which the pn junction between the drain region and substrate suffers avalanche BREAKDOWN. This breakdown usually OCCURS at voltages of 20 V to 150 V and results in a somewhat rapid increase in current (known as a weak avalanche).
