The parallel resistor is effectively shorted out by the diode. Put a drop resistor calculate its value in such a way that given the known load resistor parallel to the zener the voltage across the load in the load drop series without the zener should be grater than your zener diodes regulating voltage.

The use of diodes in parallel is commonly found in power electronic design.

Resistor parallel to diode. If the diode is considered to be ideal then you are correct to say the volt drop 0. It also means that the diode has zero resistance so the current in the circuit will be given by the supply voltage divided by the series resistor. This application note highlights the cause of the behavior of several diodes are connected in parallel.

Load voltage appears for the negative half cycle. So no load voltage appears. Considering the diode to be ideal if such a connection is employed with an energy source ac then it would result in a short circuit for ve half of ac cycle.

A diode in parallel with a gate resistor when driving a fet or an igbt is usually used to compensate for the usually slower turn off of the device so usually the diode allows the gate to drain faster. Resistors and diodes andrew masters. Although current sharing is very effective the power loss in the resistor is very high.

Overview of circuit components resistor capacitor inductor transistor. In figure 3 the current sharing resistor r establishes values of id1 and id2 that are nearly equal. We can assume the dc operation via ve half cycle of ac signal.

Current sharing resistors are required for each paralleled diode primarily to handle the negative temperature coefficient ntc effect on diode forward voltage. Calculations involving diodes and resistors in series. Parallel diodes can be forced to share current by connecting a very small resistor in series with each diode.

An important consideration for this practice is the current sharing between diodes due to the difference of electrical characteristics. This blog demonstrates how the multiple diodes can be connected in parallel with a suitable series resistance per diode.
