It is made using planar silicon epitaxial technology, and comes in a SOD-132 package with a low power dissipation capacity relative to other similar devices. This device has been designed to provide robust, versatile performance in a wide range of general-purpose and industrial electronics applications.

Application Field

Does PLZ33B-HG3/H have many real-world applications? Absolutely. It is primarily used in situations that require precise regulation of voltage or protection against overvoltage. It is also used in switching power supplies, microwave range circuits, output rectifier circuits, and circuit overvoltage protection.

More specifically, PLZ33B-HG3/H diodes can be used in precision-voltage reference circuits or other circuits in which a reliable reference value is required. Its low resistance and diffuse junction make it a good choice for use as an LED driver and transistor bias supply.

Working Principle

The PLZ33B-HG3/H device is a Zener diode, which means that its current passes through it when the reverse voltage is larger than the Zener voltage. In general, the Zener diode does not conduct current in a forward direction. When a reverse bias voltage is applied to the diode and its value exceeds a certain point, current begins to flow through it and the voltage across the diode remains nearly constant.

The breakdown voltage of the diode is caused by the depletion layer narrowing due to an increase in the electric field created by the reverse voltage being applied. This field causes electrons from the n-type material near the junction to be attracted to the holes in the p-type material. This creates a region that is depleted of charge carriers which in turn creates a high electric field, allowing current to pass through the diode.
