Introduction to PLZ 5V6 B-HG3/H

The PLZ5V6B-HG3/H is a single Zener diode designed for use in a variety of applications. The device has an anode–cathode breakdown voltage of 5.6V and is housed in the ubiquitous, two-pin SOT-23 package.It has an operating current of up to 400mA and a power dissipation rating of 500mW.

Application Field

The PLZ5V6B-HG3/H is particularly useful in low-power voltage regulation applications and can provide a stable output voltage from an AC or DC power source. It is ideal for applications requiring a low-cost, low-profile, low-voltage regulator. The device is ideal for circuits that require efficient voltage regulation with low quiescent current. It is also perfect for applications requiring low noise and ripple.For instance, the device has been used in the following applications:

• Portable device voltage regulation
• Battery chargers
• DC converters
• LED backlighting
• Motor control

Working Principle

The operating principle of a Zener diode is relatively simple. When the Zener diode is forward-biased, the diode behaves as an ordinary diode, allowing the current to flow in the forward direction through the anode and cathode terminals. However, when the reverse bias voltage is increased beyond the Zener breakdown voltage the device breaks down and the current increases exponentially. This sudden increase in current is known as a \'Zener breakdown\', and it is precisely this breakdown which makes the device useful in voltage regulation applications.When reverse-biased, the Zener diode has a drop in voltage across its terminals. This drop is known as a \'Zener voltage\', and it is the Zener voltage which stabilizes the output voltage in regulation applications. Furthermore, Zener diodes can be used to protect circuits from overvoltage conditions. When an overvoltage condition occurs, the current through the Zener diode increases exponentially, thereby preventing the voltage from exceeding the Zener breakdown voltage.

Conclusion

The PLZ5V6B-HG3/H is a single Zener diode designed for use in a variety of applications. It is capable of providing a stable output voltage from an AC or DC power source, and can be used for low-power voltage regulation applications, as well as for general protection of circuits from overvoltage conditions. The device is housed in a two-pin SOT-23 package and has an operating current of up to 400mA and a power dissipation rating of 500mW.
