Digital Isolators provide the ultimate level of isolation due to the completely electrical insulation between the isolated signals and the ground. The most common type of isolator is the Space-Insulated Isolator, SI8710BD-B-ISR, which utilizes a polymer material as insulation material of choice. This article takes an in-depth look at the SI8710BD-B-ISR application field and working principle.

The SI8710BD-B-ISR isolator is most commonly used in power conversion systems, such as power inverters and servo drives, to provide electrical isolation between two devices. This electrical isolation prevents the high voltage spikes from traveling back to the power source and potentially damaging sensitive equipment. It also enables a more efficient use of energy by preventing electrical crosstalk between the devices.

The SI8710BD-B-ISR isolator works by utilizing the unique properties of an organic polymer material, known as Kapton. Kapton is an opaque material with a dielectric breakdown strength of 15kV/mm, making it extremely resistant to electrical interference. This material is also highly resistant to heat, so it can withstand the high temperatures generated by power conversion systems.

The SI8710BD-B-ISR isolator is constructed of two metal plates, each with a layer of Kapton insulation material. The top plate is connected to the power source and the bottom plate is connected to the device that needs power. When power is applied to the top plate, an electrical field forms across the Kapton layer, which blocks any high voltage spikes from travelling back to the source. This isolator also provides a relatively low resistance path for electrical signals, allowing for an efficient transfer of power and data between the two devices.

The SI8710BD-B-ISR also has the benefit of being easy to install and maintain. The metal plates are already mounted, so it simply needs to be connected to the power source and the device that needs power. No additional hardware is needed. Additionally, since it is made of a single layer of insulation, it is very durable and can withstand extreme environmental conditions without degrading.

In conclusion, the SI8710BD-B-ISR is a perfect choice for providing electrical isolation between two devices in a power conversion system. The unique properties of the Kapton provide an extremely high level of electrical isolation while also offering a relatively low resistance path for data and power to travel between the two devices. Additionally, the SI8710BD-B-ISR is very easy to install and maintain, making it a great option for any system.The specific data is subject to PDF, and the above content is for reference
