1PMT4626E3/TR13 Datasheet/PDFDiodes - Zener - Single
The 1PMT4626E3/TR13 is a Zener diode that has a number of applications and operating principles. The most common application for it is to provide reverse voltage protection. It works by using a reverse-biased PV junction. When a reverse voltage is applied to the diode, it causes the "free" electrons from the PV junction to become attracted and create a build-up of electric field in the region. This electric field helps to reduce the current until it reaches a level low enough for the diode to stop conducting.
Zener diodes can also be used as voltage regulators. This is achieved by placing a resistor in series with the diode, so that when the voltage across the diode reaches a certain threshold, the voltage across the diode will stay constant. This is possible because the internal resistance of the diode increases as the voltage increase, and the diode stops conducting at a higher voltage limit.
The 1PMT4626E3/TR13 can also be used as a rectifier. It works by using the reverse-biased PV junction to allow current to flow in one direction while blocking the flow in the other direction. This allows the current to flow in a single direction, while still allowing some current to be absorbed by the diode.
The 1PMT4626E3/TR13 can also be used as a transient voltage suppressor (TVS). It works by using the reverse-biased PV junction to absorb excess energy generated by sudden voltage spikes. This prevents the flow of current from damaging the attached components.
The 1PMT4626E3/TR13 is a handy device for a variety of applications. It can be used for reverse voltage protection, voltage regulation, rectification, and transient voltage suppression. It is important to understand the operating principles of the 1PMT4626E3/TR13 before applying it to any project.
