SZMMSZ4701T1G

The SZMMSZ4701T1G diode is part of a single Zener diode family, designed to regulate and control power output. It is commonly used in power conversion and other purposes requiring voltage transformation or flow control. This device is usually constructed of a N-type semiconductor in combination with a P-type semiconductor.

The main application field of the SZMMSZ4701T1G is power supply management. It is a medium power, surface mount device that is ideal for use in power management applications such as switching power supplies, DC-DC converters, and other low voltage and high current applications. It is capable of regulating the output voltage over a wide range of input voltages, providing ripple free operation and excellent load and line regulation.

As for the working principle, the SZMMSZ4701T1G works by allowing a nominal voltage drop across it when the applied voltage is greater than a preset break-over voltage. This break-over voltage is usually determined by the operating temperature and current limit. The device then limits the voltage drop across it and maintains the output voltage at a steady level, even when input voltage or load changes. This steady state operation depends on the impedance value of the diode. The current limit is maintained by using a Zener breakdown mechanism.

In terms of the output voltage characteristics, the SZMMSZ4701T1G is a voltage-variable device and operates with an output voltage that is largely dependent on the zener impedance curve. During normal operation, the device will provide a voltage drop of between 0.25V to 47V, with a maximum current of 100mA. The device is also capable of providing very efficient power conversion with a power dissipation rating of 0.3W.

The SZMMSZ4701T1G has a typical PUE (power efficiency) of 90%. This is an indication that the device can effectively and efficiently convert electric energy from one form to another. Additionally, the device has a wide AC response range and a high averaging current of up to 1A. This allows it to be used effectively for fast charging applications.

In summary, the SZMMSZ4701T1G diode is a single Zener diode that is designed to regulate and control power output. It is capable of limiting voltage drops and providing steady output voltages, even when the input voltage or load is changed. The device is mainly used in power supplies, DC-DC conversion, and low voltage and high current applications. It is also able to provide very efficient power conversion with high power efficiency and excellent AC response range.
