SD101CW-HE3-18 is a single rectifier diode, with a high breakdown voltage, combined with a high surge current capability. This component is widely used in the manufacturing of circuit boards.

It is comprised of a molding compound of PN junction, which is made up of semiconductor silicon. When passing an external voltage, it will allow a current to flow in only one direction, due to the characteristics of the PN junction. Its breakdown voltage is specified at >2500V and the maximum operating temperature is 150°C.

It can be used in a variety of applications, such as high power AC-DC power supplies, bridge rectifier circuit and boost rectifier circuits. In rectifier circuits, it allows only DC signals in the output and eliminates any AC signals. It can be used in switch-mode power supplies since it has a high surge current capability and helps regulate line transients.

The diode also has a fast recovery time, ensuring quick switching between OFF and ON states which helps in controlling display backlight brightness and flicker frequency. The reverse voltage is typically limited to between 1V to 1.5V, and it can be used for a wide range of currents.

The working principle of the SD101CW-HE3-18 rectifier diode is simple. When the anode voltage becomes more positive than the cathode voltage, electrical current flows from the anode to the cathode within the diode. This current flow depends on the voltage applied to the diode. Once the voltage is greater than the threshold voltage and the diode or the junction is forward biased, the diode can conduct current.

When the anode voltage is less than the cathode voltage and the diode junction is reverse biased, no current passes through the diode. This helps in preventing unwanted currents when power is not applied or when transients or noise are present on the line.

It can also be used in power IC’s as ZVS-Flyback circuits, which helps to reduce the ringing of the output stage. The fast recovery time and high surge current capability enables it to handle large output power requirements, making it suitable for use in various high power applications.

In conclusion, the SD101CW-HE3-18 diode has a wide range of application fields, and the working principle is easily understood. It is a much needed component in many electronic circuits and devices, and provides an effective solution for many electronic circuit applications. It has become a vital component in the modern electronic markets, and has become an admired choice for many manufacturers.
