Working Principle
The 1PMT5920E3/TR7 works on the principle of a “Zener breakdown”. This phenomenon occurs when a reverse biased zener diode reaches a certain amount of reverse voltage and begins conducting current in the reverse direction. This happens because of electrical stress on the zener junction caused by the applied reverse voltage. When the voltage reaches a certain threshold, the zener diode shifts into a high conductance state, allowing current to flow in the reverse direction.
As the reverse voltage continues to increase, the current through the diode also increases and the voltage drop across the diode begins to drop. When the forward current reaches a certain level, the diode again shifts into a high-conductance state and the voltage drop across the diode stabilizes. At this point, the voltage across the diode is known as the “Zener Voltage”, and the diode is said to be in a “Zener Breakdown” state.
The 1PMT5920E3/TR7 Zener diode is designed to provide a stable output voltage that is independent of temperature and current load at the Zener breakdown voltage. This provides the user with an efficient and reliable way of regulating the output voltage of a system.
Conclusion
The 1PMT5920E3/TR7 Zener diode is an active component used for a wide range of applications such as power management, audio and video equipment, computer and consumer electronics, telecommunications, lighting controls and industrial equipment. It works on the principle of Zener breakdown, where the voltage across the diode stabilizes and provides a stable output voltage independent of temperature and load. This makes it an efficient and reliable way of regulating the output voltage of a system.
