I want to measure threshold voltage of a power mosfet, and while searching texts..I came to know that we measure Vth by:
please see Vth on page no 2 on this link.....
http://www.aosmd.com/res/application_notes/mosfets/Power_MOSFET_Basics.pdf
I want to ask that why we use specifically 250uA, whats the theory behind it ??
as i have also checked datasheets, there also they have used the same thing....please refer page 2, (testing conditions of mosfet, for Vth)
http://www.datasheetcatalog.org/datasheet/stmicroelectronics/9387.pdf
Please help....
- we connect gate to drain
- and then we pass 250uA through drain to source.
