electricpy.zener_diode_required_resistor(Vin, Vo, I)[source]

Zener diode required resistance function .

A zener diode is uses to allow current to flow “backwards” when the zener voltage is reached. This function use to calculate the required resistor value following below formula:

\[R = \frac{V_{in(min)} - V_{out}}{I_{load}+0.01}\]

Parameters:

  • Vin (float) – Minimum input Voltage in Volt

  • Vo (float) – Output Voltage in Volt

  • I (float) – Load Current in Ampere

Returns:

R – Load Resistance in Ohm

Return type:

float
