The PLZ39B-G3/H is a single zener diode designed for various applications. It has a maximum reverse voltage of 6.1V, operating temperature of -55°C to +150°C, and a thermal resistance of 125°C/W. Its low junction capacitance and reverse leakage current makes it ideal for switching, protection, and output or reference voltage stabilization. It is also suitable for regulator circuits and temperature compensation.
Working Principle
The working principle of the PLZ39B-G3/H is based on p-n junction diode behavior. It utilizes the properties of a reverse biased diode to allow current to flow in its reverse direction. At critical breakdown voltage, the diode permits a large current to pass from anode to cathode. This is called the avalanche breakdown.When an applied reverse voltage across the diode reaches a certain value (Vz), the voltage-current relationship changes radically. This is known as the \'Zener voltage\'. At this voltage, the reverse current increases dramatically and double the forward current. Above this voltage level, the diode’s resistance drops sharply and the Zener current (Iz) increases. Therefore, the diode operates in a reverse breakdown region, creating a stable reverse voltage across the diode’s terminals.Application Field
The PLZ39B-G3/H has a wide range of applications. It is mostly used in linear regulator circuits, where it is used to provide reference voltage. It is also used to provide a stable reference and output voltage in switching power supply circuits. This diode can also be used in frequency control circuits as well as temperature compensation circuits.It is also ideal for over-voltage protection circuits in equipment such as personal computers and electrical appliances. This diode is particularly useful in cell phone chargers and other low power devices, due to its low power consumption and low noise operation.The PLZ39B-G3/H is also suitable for applications that require reverse ESD protection or lightning voltage protection. It is commonly used in automotive electronics such as ECUs, ABS and airbags.Conclusion
The PLZ39B-G3/H is a single zener diode designed for various applications. It comes with a maximum reverse voltage of 6.1V, operating temperature of -55°C to +150°C and a thermal resistance of 125°C/W. It is suitable for applications that require reference or output voltage stabilization. This diode is useful in linear regulator circuits, frequency control circuits, temperature compensation circuits, and over-voltage protection circuits. It is also a great choice for automotive electronics, such as ECUs, ABS and airbags, due to its low power consumption and noise reduction properties.The specific data is subject to PDF, and the above content is for reference
