Apr 18, 2020 · The Mosfet is acting like a switch, the PWM output of the arduino should not be loaded with more than about 10mA, so for a tiny current spike at every switch on / switch off change, the …

Sep 19, 2017 · Discussed here are two circuits to perform that function. Below is the LTspice simulation of a simple ideal-diode MOSFET circuit using all transistors. The components are inexpensive, …

Dec 15, 2025 · I am using a P-channel MOSFET (SUD50P06-15L-E3 / SUD50P06-15-GnE3) as a high-side electronic switch in a 12–14 V automotive electrical system to control auxiliary lighting.

I used an H-bridge and got that working fine. Then, I decided to simplify things and get a single mosfet instead of a multi-channel H-bridge and have gotten myself very confused. I'm trying to understand …

Feb 5, 2021 · I am trying to select an n-channel MOSFET to switch a 12 V power rail. The use case here is to switch on/off a couple of LEDs which are wired in series. The LEDs (datasheet) can draw a …

When a channel exists in a MOSFET, current can flow from drain to source or from source to drain - it's a function of how the device is connected in the circuit.

Jun 14, 2021 · When The Drain and Gate of a MOSFET are connected together, A two-terminal device known as a ''diode-connected transistor'' results. if drain and gate is shorted then MOS will behave …

May 14, 2013 · I've been on this site now a couple of months and I notice various symbols used for MOSFETs. What is the preferred symbol for an N Channel MOSFET and why?

Nov 7, 2014 · Why is pulsed drain current higher than continuous drain current in MOSFETs? In MOSFET data-sheets, pulsed drain current is much higher than (by at least 2x) continuous drain …

6 Your equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the …
