Diodes are versatile electronic components designed to electronically control current flow in one or both directions, both for AC and DC uses. Among the different types, Zener Diodes are components of particular interest since they are made primarily for use in reverse breakdown, and this application field makes them useful in voltage regulation. The BZG03B200-HM3-08 is an example of Zener Diode, particularly suitable for medium to high power dissipation applications.

The BZG03B200-HM3-08 is a single diode based on the Zener principle, mainly designed for general-purpose applications. This component has dimensions of 3.2 x 2.0 mm and a maximum height of 1.4 mm, suitable for space-saving design of devices. Compared to other competitors of equal power dissipation, it offers low thermal resistance, typically of 0.5 °C / W.

The maximum average forward current of the component can reach a impressive 100 mA, while the non-operating junction temperature can range up to +175°C. The reverse current is 6 mA (at VR = 5.2V, TA = 25°C), while the reverse breakdown voltage is between 5.0 and 5.6 V.

The component has a wide range of applications. One of these is that it can be used in circuit designs that require protection against high voltage and reverse polarity. It is also used in many circuit designs that require voltage regulation, because a Zener diode works by allowing current to flow both ways, when the voltage exceeds a certain level set by the component. This is known as the Zener voltage, or the breakdown voltage of the component. When the voltage exceeds the specified level, the component breaks down, allowing the current to flow in low level, with no excess voltage.

The working principle of the component is based on the Zener effect. This occurs when a reverse biased diode is subjected to a high electric field, suspended between the cathode and anode. The high voltage applied to the diode suspends the junction and produces a finite number of electron-hole pairs combination, called carriers, which can cross the junction and thereby conducting current.

The BZG03B200-HM3-08 Zener Diode is a versatile component suitable for many applications, especially in medium to high power dissipation designs. Its characteristics, such as the low thermal resistance, maximum current forward and reverse breakdown voltage make it the ideal choice for designs that require voltage regulation, protection against high voltage and reverse current polarity.
