CLL4750A BK Application Field and Working PrincipleDiodes are components which are used to control the flow of electricity in circuits. Zener diodes, specifically, are diodes which can allow current to flow in only one direction and prevent current from flowing in the opposite direction. A Zener diode is designed to specifically \'break\' at a set voltage level and thereby allow current to flow when the applied voltage is higher than the set value, or to generally regulate or protect the circuit or equipment. The CLL4750A BK is a single Zener diode, particularly designed for voltage regulation or crest voltage protection for various electronic components or equipment. It is manufactured by STMicroelectronics and is usually used in power supplies, frequency counters, and many other components. The CLL4750A BK has a peak inverse voltage (PIV) of 500V, a surge power dissipation of 500mW, and a breakdown voltage of 5.0V.A Zener diode is made of a single silicon semiconductor and is typically operated in the "reverse breakdown region", meaning, in a reverse-biased direction. When a reverse-biased voltage is applied to the Zener diode, the voltage across the diode begins to build until it reaches the breakdown voltage of the diode. At this point the Zener diode breaks down, allowing current to pass through the diode, thus supplying the voltage to the circuit which is regulated by the set breakdown voltage.In the case of the CLL4750A BK, the breakdown voltage is set to a specific value. As such, when the applied voltage exceeds the breakdown voltage of the diode, current is passed through the diode, thus enabling the correct supply of voltage to the circuit. The CLL4750A BK also has an internal resistor, which helps to prevent the Zener diode from ‘zapping’ and causing damage to the circuit. In addition, the CLL4750A BK has a surge power rating of 500mW, meaning that it can handle higher levels of power for short periods of time, but also that it should not be used in high-power applications.Overall, the CLL4750A BK provides an excellent solution for power supplies, frequency counters, and other components which require a reliable and stable voltage supply. It is rugged, reliable, and provides excellent performance, making it an ideal choice for a wide range of components. The CLL4750A BK is an economical solution as well, providing quality and reliability at an affordable price.
