TVS diodes, also known as transient-voltage suppression diodes, are devices designed to protect electronic components against transient voltage spikes. DF5G7M2N and LF applications, in particular, are for specific uses, such as surge and ESD protection.

What is the DF5G7M2N?

The DF5G7M2N is a dual Bi-Directional Transient Voltage Suppression (TVS) diode designed for ESD and lightning-induced surge protection. It has a symmetrical symmetrical clamping action and can absorb 15A of current at 8/20μs with a peak pulse power rating of 60W. The DF5G7M2N is designed to provide protection in automotive applications, and also supports IEC 61000-4-2 / IEC61000-4-2 LV, ISO 10605 and GL-C criteria.

What is the LF Application?

The LF application, or Low Frequency, is a popular type of TVS diode which is meant for applications that require both low capacitance and low power. This makes it ideal for use as a line terminal clamp that helps to reduce ringing on the high-speed lines. It can handle peak power up to 100W and has an operating voltage between 5V and 50V. The LF TVS diode can handle up to 25A of current.

Working Principle

TVS diodes are designed to protect sensitive electronic components against transient voltage spikes. In a nutshell, when a transient voltage spike occurs, the TVS diode acts like a short circuit, allowing the current to flow through the diode and provide an alternative path for the excess electrical energy, thus protecting the device from damage. The reverse breakdown voltage of the TVS diode determines the voltage at which the diode will conduct and provide protection.

The DF5G7M2N and LF TVS diodes have symmetrical clamping actions that offer more reliable protection than diodes with more traditional designs. As the current passes through the device, it is absorbed so that the voltage across the protected device remains below the specified level, preventing any damage to it. The peak pulse power rating of the diode is an important factor, since it determines how much power it can absorb and dissipate.

TVS diodes also protect connected components from electrostatic discharge (ESD). ESD occurs when static charges build up on an object and discharge in a single electric shock, usually through an unsuspecting victim, but in this case, it’s the electrical components that are at risk. The DF5G7M2N & LF TVS diodes are designed to absorb these sudden ESD shocks and divert them away from the protected components, thus saving them from any damage.

Conclusion

TVS diodes have become a popular choice for protection against transient voltage spikes and ESD shocks in automotive electronics. The DF5G7M2N and LF applications are specifically designed to provide higher levels of protection, thanks to their symmetrical clamping action and peak pulse power ratings. With these devices, manufacturers can ensure that their cars remain protected from the risks of ESD and voltage spikes.
