mosfet gate drive impedance
gearhead - 15:15 14-01-08
I have a situation where I need to use a pretty stiff pull-up resistor
on a mosfet gate because I'm going to use a comparator
to turn it off, and I plan to limit the current the ... Read More

mosfet driver question
14:35 12-01-07
I'm thinking of getting a TC1427 mosfet driver to power a motor by
parallel port. I'm about to place the order, then I thought of a few
questions:
Can I drive a 1A load direc... Read More

Mosfet
Roger Dewhurst - 17:44 15-10-07
How are the pins of a mosfet identified please.
The project requires a 45V/16A Schottky diode or similar. I cannot find a
supplier. What is special about a Schottky diode? ... Read More

Mosfet as a 12V Switch (and opto)
ProgrammerChicago@gmail.com - 12:46 07-10-07
I've been stuck on this for awhile. I've got a MOSFET that is not
behaving the way I expect.
I was hoping it would act similar to the following animation where

mosfet? transistor? hexfet?
14:46 21-12-06
When would one use a transistor? mosfet? hexfet?
Basically looking into PWM switching of medium-sized DC motors (12V,
~5A or so).
Which should I use...? A beefy transisto... Read More

MOSFETs and PWM
Randy Day - 13:05 24-02-07
I've built some TTL motor/relay controllers
out of NPN transistors in a Darlington
configuration, and I'm considering using
mosfets instead.

nulling offset in a comparator
gearhead - 16:46 29-12-07
I need a blocking diode that will
conduct about ten amps. I have a
leftover comparator out of a quad,
so I decided to use parts the circuit
already has and run the comparator

MOSFET ratings
Jon Slaughter - 21:23 07-04-08
Does the current rating of a mosfet take into account all maximum
circumstances under normal operating circumstances? e.g., basically if it
says X amps and I run it < 80%X or ... Read More
