Diode forward voltage at low current. The forward voltage at a specific forward current is also lower for a schottky barrier diode than for a pn junction diode. A diode forward voltage refers to the voltage drop that occurs when an electrical current passes through a diode in an electrical circuitit is generally independent of the amount of current passing through the diode and will be the same for a given family of diodes. This recombination can occur within the quasi neutral regions within the depletion region or at the metal semiconductor ohmic contacts.

Current consumption of my rtc module is only 14ua i think i should find a diode whose reverse current is lower than 02ua to reach the minimum cost. For example at 2 ma forward bias current a low barrier silicon schottky diode will have a forward voltage of 03 volts while a silicon pn junction diode will have a voltage of 07 volts. But this simple rule that low forward voltage drop corresponds to low switching loss does not hold for real schottkys of type voltage above approximately 80 v.

Under forward bias the diode current is due to recombination. The diode will work for sure with extremely low forward voltage. But keep in mind the reverse leakage current which is far more than your actual forward current if you are designing low power battery operated device.

I found in4148 but the forward voltage is too high and some schottky diode has the low enough forward voltage but the reverse current is too high 10ua. In real life diodes only conduct current once the voltage is above a certain level and they tend to leak minute amounts of current when blocking the reverse voltage. For silicon diodes which are generally the most common the diode forward voltage drop is about 07 volts v.

For ultra low power use and the low voltage levels involved you need to be careful about the type of diode used. The current in a p n diode is due to carrier recombination or generation somewhere within the p n diode structure. We have to take into account that forward voltage drop is the sum.

These schottky barrier diodes are designed for high current handling capability and low forward voltage performance. Features low forward voltage 024 volts typ at if 10 madc.
