Introduction
The 1PMT5955A/TR7 is a single Zener diode designed to regulate and protect circuits from electrical over-voltages. It is used in a variety of applications, but is most commonly employed in clipper circuits. This article will discuss the application field and working principle of the 1PMT5955A/TR7.
Application Field
The 1PMT5955A/TR7 is used in many different applications. It can be used to regulate the amount of current passing through a circuit. Specifically, it can be used in clipper circuits in order to prevent surges of high voltage. It can also be used to reduce electro-magnetic interference from one circuit to another, and in electronic voltage regulators.
Additionally, the 1PMT5955A/TR7 is often used in in high-voltage switching circuits. These circuits are designed to switch at the moment when an electric current reaches a certain voltage. Therefore, the 1PMT5955A/TR7 can act as a protector from too much voltage in this type of circuit.
Working Principle
The 1PMT5955A/TR7 works as a regular diode, allowing current to flow in only one direction. This means that any attempted current from the reverse direction is blocked. It is different from regular diodes, however, in that it allows some current leakage when the voltage applied to it is greater than a certain threshold.
This characteristic is possible due to the 1PMT5955A/TR7 having two descending parts connected in series, with a breakdown voltage separating them. The breakdown voltage is a specific voltage of which the reverse current begins to increase dramatically, allowing it to act as a voltage regulator. Therefore, the 1PMT5955A/TR7 is able to limit the voltage across a circuit to its breakdown voltage.
Conclusion
The 1PMT5955A/TR7 is a single Zener diode that is capable of regulating the amount of current through a circuit, as well as reducing electromagnetic interference. It works by employing two descending parts separated by a breakdown voltage, with the breakdown voltage limiting the voltage across the circuit to itself. As such, it can be used in a variety of applications, from clipper circuits to high-voltage switching circuits, in order to protect circuits from electrical over-voltages.
