SMDJ45A R7G

A Transient Voltage Suppressor (TVS) Diode is a type of diode that can be used to protect circuits from voltages that are outside of their normal operating voltage range. The SMDJ45A R7G is an example of a TVS diode. It is designed to protect electronics from transients from inductive or capacitive loads, or from sudden voltage surges above the breakdown voltage (VBO) of the diode. The diode clamp voltage (VClamp) is typically less than the breakdown voltage by about 1V.

The SMDJ45A R7G is a 5.8V axial-lead unidirectional diode. Its flat lead construction gives it maximum insertion depth and coverage of most PCB designs. It is rated for a peak pulse power of 500W, with a surge current of 10A. Its low capacitance and reverse leakage current give it superior transient protection from spikes and power supply fluctuations.

The diode can be used in various applications including power supplies, circuit protection, industrial control systems, DC/DC converters, and avionics. It can also provide protection for computers, communications, and consumer electronics where overvoltage transient protection is required. The diode is fitted to the application in order to divert the surge through the diode, rather than the actual circuitry. The main purpose of the diode is to protect sensitive devices from damage or malfunctioning due to the presence of a high voltage.

The working principle of SMDJ45A R7G TVS Diode is based on the Zener breakdown effect. When reverse biased, the diode allows avalanche to occur in the near junction area when the voltage applied to the diode exceeds a certain value. This avalanche helps to reduce the voltage below the breakdown voltage, thus protecting the device from overvoltage and transients. The diode can be used as a single device or in series with other components to protect the circuit from all types of ESD and EFT events.

In summary, the SMDJ45A R7G is an axial-lead unidirectional Transient Voltage Suppressor (TVS) Diode designed to protect electronics from transients, overvoltage, and ESD and EFT events. It offers excellent surge current and power rating, as well as low capacitance and reverse leakage current. The diode can be used in various applications including power supplies, circuit protection, and consumer electronics. The diode is a reliable way to protect sensitive devices from damage or malfunctioning due to high voltage transients.
