Working Principle

The CZRU52C39 consists of a zener diode and a complementary N-Channel MOSFET, designed for linear regulation of a wide range of input voltages. The zener diode is responsible for voltage regulation, while the MOSFET provides over-current protection. When the input voltage exceeds the zener diode\'s breakdown limit, it will allow the excess current to flow through the device. This current is controlled by the MOSFET and it is used to reduce the output voltage to the required value. The voltage is then regulated by a loop, which senses the output voltage and adjusts the MOSFET current to ensure that the output voltage remains within the desired range.
