I'm planning to use this MOSFET as on/off switches for various loads ranging from roughly 100 to 250VDC and 0.1 - 1A. I believe it to be more than adequately sized. I can also add quite a bit of cooling power if needed (although I think even that may be largely unnecessary.) They won't be switching often, they'll completely on or off for several hours at a time between switches.
The drive voltage is listed as: Drive Voltage (Max Rds On, Min Rds On): 10V I'm a bit confused as to how maximum and minimum can be the same value.
Here is the chart that I think is most relevant to my question:
Question 1: The gate doesn't need any specific amount of current, correct?
Question 2: Am I correctly interpreting the plateau in this graph to say that if I use 9V to drive the gate instead of 10V that the FET will operate nearly identically to 10V? I simultaneously think and hope that this is the case.
Question 3: What happens if I apply 12V to the gate? Do I insta-fry it, does it slowly cause damage, is it totally fine?
Bonus: Explain what's going on with both RDS minimum and maximum both being 10V.
The reason I ask is that I can most easily supply 12V or 9V to the gates. Sourcing a perfect 10V is in no way prohibitively difficult, but it would be a bit more of a pain than using 9 or 12, based on what I have on hand. I understand that the truest answer to the title of this post is likely "10V, you dummy" but I'm hoping one of either 9V or 12B will suffice. I don't need perfect precision for my application, I just need to not fry the FETs.
