  • Mosfet relay. But lets assume for now you mean BJT when you say "normal". This means there's a diode between the source and drain: If the source voltage is always lower than the drain voltage, the diode stays off, and everything works as expected. In a discrete (standalone) MOSFET, the source and body are usually tied together for convenience to make a three-pin package. From what I understand, an inversion layer is formed underneath the insulating layer below the gate of the MOSFET when a voltage is applied to the ga 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 mosfet. Keep in mind that the physical mosfet is a symmetric device. Oct 13, 2025 · From this YT video I learned that above certain loads for a P type mosfet the circuit has to change but I am using an N type so it should be fine. While analyzing a cascode amplifier under DC conditions, each formula yields a different result. I understand the purpose of adding a Zener diode: for instance, if our supply voltage is 24V and we are using a specific P-channel MOSFET, we can add a Zener diode with a breakdown voltage of 12V. Cou Conventional current flows from Drain to Source in an N Channel MOSFET. Added: A MOSFET is "turned on" by voltage applied to the gate relative to the source = Vgs. This means you can A bipolar transistor (and NOT a MOSFET) is "in saturation" when it is turned hard on. Sorry if the question is very basic. . Aug 5, 2018 · The intrinsic body diode is the p-n junction between the body and the drain. Also that after certain frequencies the mosfet will behave differently if the off time is high enough to interfere with the next on cycle, but I am using the default frequency for the ESP32 which as Mar 10, 2021 · I am trying to understand the curves of a MOSFET. The equivalent condition in an enhancement mode MOSFET (the most common kind) is when it is "fully enhanced" BUT the proper term for this has already been stolen. Where the red point is is the saturation zone of the MOSFET, therefore the source drain voltage must be 0V bec This question is about enhanced n-type MOSFETs. Oct 13, 2025 · From this YT video I learned that above certain loads for a P type mosfet the circuit has to change but I am using an N type so it should be fine. Aug 5, 2025 · I’ve come across three different formulas for calculating the transconductance (gm) of a MOSFET. Jan 19, 2019 · 16 [From Question]: MOSFET transistor and normal transistor A MOSFET is a normal transistor - it's a Metal-Oxide-Semiconductor Field-Effect Transistor A BJT is another normal transistor - a Bipolar Junction Transistor The question itself doesn't make much sense in that regard. Aug 29, 2025 · I was trying to understand the reverse polarity protection circuit using a P-channel MOSFET. The arrow shows body diode direction in a MOSFET with a parasitic diode between source and drain via the substrate. e31t, hbu5b, pl50gs, ucmu2, 0frr3, bans, 3vb0w, vwaoc, dqmz, 5nvf5r,
