Transient voltage suppressor (TVS) diodes are electronic components designed to protect networks and other electrical systems from voltage spikes caused by technological events such as lightning strikes, power surges, and electrostatic discharges (ESD). TVS diodes fit into a series of classifications based upon their structure, polarity, and power ratings. DF2S5.1FS,L3M is a type of TVS diode that can be applied to a variety of systems, often in automotive applications, for ESD protection. In this article, we will discuss the application field and working principle of the DF2S5.1FS,L3M type of TVS diode.

The DF2S5.1FS,L3M diode is a small, dual-channel, dual-plug diode with a low peak pulse power rating of 5.1 watts (W). Its maximum reverse stand-off voltage is 6 Volts (V), and its maximum clamped voltage is 10.6 V. This makes it suitable for applications that require ESD protection from low-voltage surges, such as automotive circuit boards. The DF2S5.1FS,L3M diode is commonly used in Automotive Ethernet, USB ports, HDMI ports, and CAN bus systems, among other applications.

The working principle of the DF2S5.1FS,L3M type of TVS diode is based on a simple two-terminal arrangement. The diode can be plugged into a PCB as a single component. When the voltage across the diode’s terminals reaches its reverse stand-off voltage (6V), it enters the breakdown region and starts to conduct current. As the voltage increases further, the current through the diode rises exponentially. Thus, when a voltage spike occurs, the TVS diode will quickly start conducting and clamp down the voltage to its maximum clamping voltage of 10.6 V.

In summary, the DF2S5.1FS,L3M type of TVS diode is a dual-channel diode with a low peak pulse power rating. It is often used in automotive applications for ESD protection, with applications including Automotive Ethernet, USB ports, HDMI ports, and CAN bus systems. Its working principle is based on a two-terminal arrangement, where it can be plugged into a circuit board and used to quickly clamp down voltage spikes. Overall, the DF2S5.1FS,L3M type of TVS diode is a useful component for providing protection from electrical surges.
