Diodes are one of the most widely used components in electronic circuits. Zener diodes are a subclass of diodes that are used to provide consistent voltage regulation, surge protection and signal clamping. The BZG05C91TR is a single Zener diode particularly useful for providing constant voltage regulation and protecting against over voltage surges in a wide range of applications.
Application Fields
The BZG05C91TR diode is a Zener diode used to secure voltage sources from dips, spikes and surges. It is designed to protect electronic and electrical components from damages due to sudden overvoltage (voltage discrepancy), typically in the range of ±10% of the nominal voltage. As transistors and other electronic components are typically rated for a specific operating voltage, the BZG05C91TR diode is an effective way to maintain that voltage level by clamping the voltage spikes below its breakdown voltage (VZ), assisting electronics to operate within a safe voltage range.
The BZG05C91TR is mainly employed for low power applications, when the safety and career of sensitive devices are important. It is often used in emergency lighting, alarm systems, LCD backlights, computers, digital televisions, automotive components and other telecommunications-related systems.
Working Principle
Any Zener diode is inherently bi-directional and is composed of a heavily doped p-n junction. It is built to allow the current to flow freely in both the reverse and forward directions.
When the device is operated in the reverse direction, it\'s characteristic breakdown voltage (VZ) is not exceeded until the specific amount of reverse bias voltage is applied to it. After the voltage VZ is reached, the current through the device increases exponentially, a behavior which is known as the Zener breakdown.
A Zener diode is designed to breakdown at a specific reverse voltage, this creates a steep increase in the current passing through the diode, thus clamping the voltage to the breakdown voltage. When operating in normal conditions, the Zener diode appears as an open switch, allowing no current to flow, thus effectively preventing any potential damages due to overvoltage.
The BZG05C91TR diode has a breakdown voltage of 5.6 volts, meaning it will start to conduct somehow around 5000 Volts, this is the main property that makes it ideal for surge and overvoltage protection. If the voltage rises to 6.1 Volts, the diode will allow up to 130 mA of current to flow. Furthermore, the device has a maximum power rating of 500 mW.
In summary, the BZG05C91TR is a single Zener diode used for low power applications which provides voltage regulation, overvoltage protection and signal clamping. It is useful in a variety of applications, such as emergency lighting, automotive components, computers, LCD backlights, alarm systems and other telecommunications-related systems. The device has a breakdown voltage of 5.6 volts, and will start conducting when it reaches 5000 volts or 6.1 volts, allowing up to 130 mA of current to flow. The maximum power rating is 500 mW.
