Working Principle

The SML4752HE3/5A is a Zener diode, which is essentially a single diode connected in reverse bias. As a conducting element, the Zener diode allows current to flow in one direction and blocks it in the opposite direction. When connected in reverse, a Zener diode diode behaves like an ordinary diode. That is, it blocks any reverse bias current.

Once connected, the Zener diode will behave differently depending on the voltage applied. When reverse biased, the diode behaves similarly to a regular diode, but when the applied reverse voltage is greater than the VZ value, a depletion region forms in the junction that effectively ‘short circuits’ the junction. This action limits the voltage across the junction regardless of the voltage applied and the current that must flow through the junction to keep the gap filled.

The Zener diode is used in this way to establish a precise voltage reference for power supplies, voltage regulators, and other circuits where precise voltage control and regulation is necessary. As a single diode connected in reverse, the SML4752HE3/5A makes a perfect Zener diode for almost any application and excels at voltage regulation.
