What is breakdown voltage and saturation current?
(N/A) $1$. Breakdown Voltage: It is the minimum reverse bias voltage applied to a $P-N$ junction diode at which the junction breaks down and a large current flows through it. This occurs due to Zener effect or Avalanche effect.
$2$. Saturation Current: In a $P-N$ junction diode under reverse bias,the current is due to minority charge carriers. This current is very small and remains almost constant regardless of the increase in reverse bias voltage. This constant current is known as the reverse saturation current $(I_0)$.

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: $A$ diode under reverse-biased condition provides very small current which is nearly independent of voltage until a critical limit at which the current increases drastically.
Reason $R$: Below the critical voltage limit, only majority charge carriers flow which increases drastically above critical voltage.
