SMDJ10AHR7G TVS - Diodes Application Field and Working Principle

TVS - Diodes, also known as Transient Voltage Suppressor, Transient Suppressor or just Transil, are very specific kind of diodes which have been specifically designed to help protect sensitive electronics such as microprocessors, analog ICs, and other components from potentially destructive transients that arise from external sources such as electrostatic discharge. The SMDJ10AHR7G is a special Twin-Typed Zener Diode that provides transient voltage protection up to 10V and a breakdown voltage of 7.2V. This diode has become an invaluable asset for protecting delicate electronic components from destructive transients.

Application Field of SMDJ10AHR7G TVS - Diodes

The SMDJ10AHR7G TVS - Diodes can be used in a variety of applications. It is most commonly used as an automotive power line protection for engine control units and other modules, as well as in industrial applications such as AC/DC converters, motor control panels, and computer peripherals. The SMDJ10AHR7G has also found application in home theater electronics, printers, and in telecommunications equipment. Additionally, because of its low capacitance and high frequency response, the SMDJ10AHR7G is suitable for use in applications where high-frequency signals need to be protected from transient voltage spikes.

Working Principle of SMDJ10AHR7G TVS - Diodes

The SMDJ10AHR7G TVS - Diodes works on the principle of voltage breakdown. When the voltage across the diode exceeds a certain threshold, known as the breakdown voltage, current begins to flow freely through the diode. This creates a short circuit, which absorbs the surge energy and prevents it from damaging the delicate electronics connected to the diode.

The breakdown voltage of the SMDJ10AHR7G is 7.2V, and it is capable of absorbing transients up to 10V. This means that it can effectively protect a connected electronic component from voltage surges of up to 2.8V. Additionally, the diode is bidirectional, meaning that it can absorb voltage surges regardless of their direction of flow.

When a transient voltage spike occurs, the SMDJ10AHR7G diode immediately conducts current, creating a low impedance path for the current to flow through. The surge current is then quickly dissipated as heat, which limits the voltage across the protected component to a safe level. The diode also has a very low dynamic resistance of 10 Ω max., which helps to ensure that the transient voltage spike is quickly reduced.

The SMDJ10AHR7G TVS - Diodes is also designed to ensure that the protected component returns to its normal operating voltage as quickly as possible. The diode has a capacitance of 4pF max., which helps to reduce the time it takes for the diode to return to its normal breakdown voltage level.

Conclusion

The SMDJ10AHR7G TVS - Diodes is a versatile and reliable diode that provides efficient protection against destructive voltage transients. The diode has a low breakdown voltage of 7.2V, a high transient voltage absorption capacity of up to 10V, and a low dynamic resistance of 10 Ω max. It has been used in a variety of applications, including automotive and home electronics, telecommunications, industrial power line protection, and computer peripherals. The SMDJ10AHR7G is an invaluable tool for protecting delicate components from damaging voltage transients.
