# Relationship between Vgs ang Vds

Above is the output characteristics graph of IRFZ44N mosfet. As we can see, the output for various Vgs values are plotted. The highest two Vgs values (10v, 15v), have their Vds points halted below 10v whereas other Vgs values have their corresponding vds output going all the way above 10v. So is that means at vgs above 10v, the corresponding Vds output will be limited at that voltage range? Or else they are for some other reasons?

• Peak current limitation. – winny Nov 26 '19 at 17:15
• Plus power dissipation limits. For the 10V and 15V curves, they stop at about 150 watts and 3 volts Vds. This is equivalent to about 450 watts. – WhatRoughBeast Nov 26 '19 at 18:11
