Apr 26, 2025 · No. A zener diode alone will not work. If the voltage exceeds the zener voltage, the zener diode will die a quick death followed by the gauge. You need to put a resistor ahead of …

Oct 2, 2015 · The voltage drop will increase as the current thru the diode increases, so to say Forward voltage drop specifies the voltage at which the diode will start conduction is not …

Dec 29, 2024 · Having corrected the input voltage in the simulation, I find that a resistor of 470Ω in series with the diode brings the voltage back to as expected and adds back in the missing …

Dec 10, 2018 · As soon as the transistor collector voltage builds up to within one diode-drop of the supply voltage after it shuts off, the diode starts carrying the inductive current, preventing a …

Feb 15, 2025 · The Zener diode as a reference is like a seesaw at the balance point where voltage and current are in a stable configuration. If you try to draw current away from the …

May 26, 2024 · If you don't want to edit the standard.dio file you can get a reasonable 3V zener model thus :- Place a diode symbol on your schematic. Click 'Pick new diode'. Click on an …

Nov 24, 2022 · As a rule of thumb, when designing a circuit, the voltage drop across a common silicon diode is usually taken to be about 0.6V. A Schottky diode voltage drop is about 0,3V. …

Oct 6, 2020 · The diode forward voltage is actually has logarithmic relation to the diode current, it's just that at typical small diode currents, the forward drop is about 0.7V.

Oct 28, 2021 · You don't calculate the voltage across the diode. You assume a typical value of between 0.6 and 0.7 Volts. Then you solve for the currents and see if they match your …

Jan 25, 2024 · Ya, the body diode is still presented. You can check it with multimeter (diode mode) without connecting mosfet to circuit. Gate has to be discharged/shorted with source …
