Working Principle

The 1PMT5939A/TR7 operates by using the Zener effect to create a stable voltage reference. The Zener effect occurs when a reverse-biased p-n junction diode is exposed to a certain level of voltage. As the voltage increases beyond this level, the diode starts to conduct in a reverse bias direction, maintaining the voltage level with low leakage current. The diode is then able to maintain a stable reference voltage with a low drain current consumption.
