WebIf we assume that each LED has a voltage drop across it when illuminated of 1.2 volts, then the voltage drop across all three will be 3 x 1.2v = 3.6 volts. If we also assume that the three LEDs are to be illuminated from the same 5 volt logic device or supply with a forward current of about 10mA, the same as above.

WebOct 3, 2011 · ok I am going to use the total voltage for the voltage drops in each diode. So for D1, the voltage drop would be Vd1 = VR - .7. Which is Vd1 = 36-.7 = 35.3 For D, the voltage drop would be Vd = VR - .3. Which is Vd = 36-.3 = 35.7 Does that help? No, in fact it's rather bizarre The voltage drop across the silicon diode is 0.7V. WebCON), body-diode conduc-tion losses (P BD), and gate losses (P GATE). There are no switching losses because of the body diode. The body diode conducts and the voltage across the FET is the diode voltage, which is zero. The body diode ensures zero-voltage switching per Equation 7.
