DD82S08KHPSA1 Datasheet/PDFThe DD82S08KHPSA1 is a low-cost surface mount device made up of an array of 8 ultra-fast, low-capacitance diodes. It is ideal for applications involving ESD protection, signal and power line protection, and transient and surge overload protection. Each of the diode has its own anode, cathode, and isolated Anode-Cathode terminals. The common Anode is also connected to one side of the device, allowing the application of a single external bias requirement.
ESD (electrostatic discharge) protection is the first and foremost requirement when designing signal and power line protection devices. This device is capable of providing ESD protection at levels of up to 30KV on its common anode and up to 15KV on its individual anode-cathode pairs. It offers excellent signal line ESD protection and fast response to transient overvoltage conditions, making it suitable for consumer and telecom applications.
The working principle of the DD82S08KHPSA1 is based on its Bidirectional symmetrical diodes. These diodes are designed in such a way that each diode acts as a pair of diodes with one polarity, and the other polarity being used to protect the device from overvoltage. It also offers superior surge overload protection at peak currents up to 8A. It is available in an SMD package, allowing it to easily be mounted onto circuit boards.
The DD82S08KHPSA1 is well suited for applications requiring signal and power line protection as well as protection from transient voltages. It is also used in consumer applications like telephones, computers, gaming consoles, and audio/video equipment. Additionally, it is also suited for energy-saving applications, since it is capable of providing low-current protection at low Anode voltages.
In summary, the DD82S08KHPSA1 is an ultracompact, low-capacitance, low-cost surface mount device ideal for high-speed signal line protection from ESD (electrostatic discharge) and transient voltage overloads. It offers bidirectional symmetrical diode protection at peak currents up to 8A and can be used in a wide range of applications, such as consumer, telecom, energy-saving and various other applications.
