Diodes - Zener - Single

1PMT5938BE3/TR7 is a series of single zener diodes used in a variety of applications requiring reverse connection protection, overvoltage protection, or high reverse voltage protection.

Application Field

Zener diodes are widely used for their ability to conduct electricity in a reverse direction, allowing them to be utilized for a variety of adjustable voltage regulation or voltage stabilization applications. As single zener diodes, 1PMT5938BE3/TR7 can be used as a standalone diode in adjustable voltage regulators, voltage references, or as part of a voltage divider. Additionally, as part of linear or switching power supplies, 1PMT5938BE3/TR7 can protect circuits against accidental overvoltage and reverse voltage protection. Furthermore, the 1PMT5938BE3/TR7 is beneficial in low and medium noise analog applications where the tight tolerance and low leakage are beneficial in order to reduce any noise produced by the diodes. All of these applications rely on the 1PMT5938BE3/TR7 series of single zener diodes.

Working Principle

The 1PMT5938BE3/TR7 is designed to regulate the output voltage within a certain range when connected to an alternating or direct current source. Zener diodes have a unique breakdown phenomenon referred to as Zener Breakdown in which the voltage applied to the diode exceeds the breakdown voltage and the diode begins to conduct current. This breakdown voltage, known as the Zener Voltage (or Vz), is the unique characteristic of a 1PMT5938BE3/TR7 diode. This property allows it to be used in voltage regulation and voltage stabilization applications. When the voltage applied to the diode is below the Zener Voltage, the diode behaves like an open circuit, allowing no current to flow through. If the voltage applied to the diode is above the Zener Voltage, it will quickly start to conduct current in a reverse direction, limiting the voltage to the Zener Voltage.

When the 1PMT5938BE3/TR7 is connected to a voltage source, it works as a voltage regulator. When the voltage applied to the diode is less than the breakdown voltage of the diode, the diode will remain leaking-free. As the voltage applied to the diode begins to exceed the Zener Voltage, the diode will begin to conduct and regulate the voltage to the Zener Voltage. This allows the 1PMT5919BE3/TR7 to be used in a variety of voltage regulation or voltage stabilization applications requiring a certain output voltage.

The 1PMT5938BE3/TR7 is also beneficial in applications that require reverse connection protection. As the diode will quickly conduct a reverse voltage, it works well in protecting circuits against damage due to incorrect connections or over-voltages. As the diode will conduct a reverse current, it is able to divert the over-voltage away from the circuits, limiting the amount of voltage that is applied.

In conclusion, the 1PMT5938BE3/TR7 series of diodes is an ideal choice for applications requiring voltage regulation, voltage stabilization, over-voltage protection, or reverse voltage protection. With its tight tolerance and low leakage, the 1PMT5938BE3/TR7 series of diodes are an ideal choice for a variety of applications.
