What is the desired ratio between the forward and reverse biases of a regular diode?

The desired ratio between the forward and reverse biases of a regular diode is typically around 10 to 1. This means that in normal operating conditions, the diode is designed to conduct current efficiently in the forward bias condition while effectively blocking any current in the reverse bias condition.

In forward bias, a diode allows current to flow through it when the voltage exceeds a certain threshold (the forward voltage drop), thus facilitating the intended operation in circuits, such as in rectification or signal amplification. Conversely, during reverse bias, the diode prevents any significant current from flowing until a certain voltage level is reached (known as the breakdown voltage).

The 10 to 1 ratio reflects a balance that ensures the diode performs optimally; it allows sufficient forward conduction while effectively limiting the reverse leakage current. This ensures better reliability and efficiency in electronic circuits where diodes are employed, by minimizing losses and potential damage from unintended conduction in reverse bias.
