Introduction

The SS35HE3/57T is a rectifier diode that is commonly used in electrical buck converters. It is a high current device with a maximum blocking voltage of 800V and a maximum forward current rating of 35A. It is designed to provide low forward voltage drop, low leakage, and good current handling capability. As a rectifier diode, it serves to block current from flowing in the reverse direction, allowing current to only flow in one direction. This makes it a critical component in electrical buck converters, where it is necessary to regulate the amount of current that flows through the device.

Application Field

The most common application for the SS35HE3/57T is in electrical buck converters. The buck converter is a type of DC-DC converter that is used to reduce the input voltage of a system or device while providing a regulated output voltage. The key to the buck converter is that it uses power switches and capacitors to step down the input voltage while regulating the output voltage and current.The SS35HE3/57T is typically used as the main switch in a buck converter, controlling the flow of current on and off in accordance with the input and output voltages. In this way, it is able to regulate the output current, allowing the buck converter to maintain a constant output voltage regardless of the input voltage.

Working Principle

The working principle of the SS35HE3/57T is based on the PN junction semiconductor structure. This is a device made from two different semiconductor materials, a p-type semiconductor and an n-type semiconductor, that are in contact with each other. The p-type semiconductor is made up of positively-charged ions, while the n-type semiconductor is made up of negatively-charged ions.When the junction between the two semiconductors is connected to a power supply, the PN junction behaves like a diode, allowing current to flow in only one direction. This makes the SS35HE3/57T the perfect choice for use in buck converters, as it allows the input and output voltages to be regulated without allowing current to flow in the reverse direction.

Conclusion

The SS35HE3/57T is a rectifier diode that is commonly used in electrical buck converters. It is designed to provide low forward voltage drop, low leakage, and good current handling capability, allowing for efficient and reliable power control. Its PN junction semiconductor structure allows it to act as a diode, allowing current to flow in one direction while blocking current in the opposite direction. This is the key to its ability to regulate the input and output voltages in electrical buck converters, making it the perfect choice for low cost and reliable power management.
