TVS - Diodes are a type of semiconductor devices designed to protect against overvoltage conditions such as electrostatic discharge (ESD) and power, electrical, and lightning transients. The SA70AHR0G device is a bidirectional transient voltage suppressor (TVS) selected for high surge current and low stand-off voltage.

Application Field of SA70AHR0G

The SA70AHR0G bidirectional Protection Diode TVS can be used across a wide range of applications such as the automotive, consumer electronics, computer, telecom, and industrial markets. In automotive applications the diode can be used to provide a fast response to propagating transients from coil-on-plug ignition systems. In addition, on-board switching power supplies and industrial applications are protected from spikes, as well as power supply distributed on vehicle board. In telecom and data communications, telecom, industrial and computer applications SA70AHR0G can protect interfaces and systems from high-speed data transients.

Working Principle of SA70AHR0G

SA70AHR0G Protection Diodes are made from a light-sensitive semiconductor die, with an etched p-n junction surrounding the diode\'s main body. The working principle is based on the basic Design Structure of the P-N Junction. When a voltage higher than the device stand-off voltage is applied on the two leads of the diode, the avalanche breakdown of the junction between the P-type and N-type regions of the wafer occurs. This develops a strong electric field across the junction of the diode, causing the release of charge carriers into the conduction band and results in a large increase in the current flow. This current quickly dissipates the energy stored in the applied overvoltage condition thereby protecting the surrounding circuitry.

The key features of the SA70AHR0G Protection Diode TVS include low capacitance, fast switching speed, reliable transients protection, low stand-off voltage, and a high level of easy to install integrated protection. In comparison to other commercial devices, this device is designed to respond faster to high-voltage transients while also offering consistent performance.

The SA70AHR0G TVS Diode is capable of providing transient protection up to 6.5kV, with fast response time of less than 1ns. In addition, the device is available in three lead package sizes of UniDoc, Mini Doc or Duo-Doc. Due to its unique size and mounting options, the diode can easily be integrated into various circuit designs, offering enhanced protection for a wide range of circuit designs.

In summary, the SA70AHR0G protection diode TVS is a reliable TVS device designed to serve a wide range of applications. With its unique size and mounting features, the diode can easily be integrated into various circuit designs. With fast response times of less than 1 ns, efficient transient protection from 6.5kV, and enhanced protection from high-voltage transients, the device is a cost-effective solution for many circuit designs.
