Diodes - Zener - Single

A GDZ4V3B-HE3-18 is a single zener diode that is suitable for a variety of applications. It has a maximum peak reverse voltage (VR) of 3.6 V, providing moderate power output and reliability. It has a thermal resistance rating of 0.75 °C/W making it a suitable choice for moderate temperature environments.

Generally, a diode is an electronic component that allows electricity to pass in one direction and blocks electrical current in the opposite direction. A zener diode is a type of diode that has a high reverse breakdown voltage, allowing it to control the voltage across an electronic circuit. A single zener diode consists of a single diode connected one way, while the maximum peak reverse voltage is defined by the breakdown voltage of the diode.

The GDZ4V3B-HE3-18 is an ideal device for many applications. It can be used as a simple clamp or as a voltage limiter in circuits, where it maintains voltage levels to protect components from over-voltages. It can also be used as a voltage regulator in circuits, where it can provide a consistent voltage level. It can also be used in switching circuits, as it can control the current in a circuit and ensure that it is the correct level.

In addition, the GDZ4V3B-HE3-18 can be used for protection against electrical transients, or spikes in voltage or current. Since it has a reverse breakdown voltage, it is able to absorb and dissipate any excessive voltage or current in the circuit, thus protecting other components. This feature is particularly useful in automotive and industrial applications, where power fluctuations and surges are more common.

The working principle of a GDZ4V3B-HE3-18 is based on the voltage-current relationship of a p-n junction diode. When forward biased, the diode acts as a low-resistance "electrical conduit" and allow electrons to freely pass through it. When reverse biased, a potential barrier is formed at the p-n junction, making it harder for current to pass through the diode and limiting the current.

At first, the current through the diode may be small and insignificant, but eventually, the voltage across the diode will build up until it reaches the maximum peak reverse voltage. This is known as "breakdown voltage" and once this point is reached, the resistance of the diode dramatically decreases, allowing larger amount of current to flow.

The GDZ4V3B-HE3-18 is a versatile component that can be used in a variety of electronic circuits and applications. It is ideal for power circuits and automotive applications, where it can provide protection from environmental transients and ensure the correct level of current. It is also great for protection circuits, where it can provide protection from high current levels. Thus, the GDZ4V3B-HE3-18 is a great choice for any application requiring a reliable, power controlled, single zener diode.
