DF3A3.3FU(TE85L,F)

TVS (or transient voltage suppressor) diodes are electronic components that are primarily used for safeguarding against voltage spikes and overvoltage transients resulting from electromagnetic interference (EMI) and electrostatic discharges (ESD). The DF3A3.3FU(TE85L,F) is a type of TVS diode which is made from a unique construction of a tiny (less than 0.5mm) zinc oxide varistor which is sandwiched in between two external layers of aluminum electrodes. They are especially well-suited for applications requiring highly reliable overvoltage protection in small form factors.

The DF3A3.3FU(TE85L,F) is characterized by its fast response time (less than 1 nanosecond), a wide operating temperature range from -55°C to 85°C, and excellent power clamping capabilities. It is primarily used to protect sensitive electronic components, such as microcontrollers, microprocessors, and other ICs, from high voltages. Its small size and low profile make it perfect for applications with space restrictions. The DF3A3.3FU(TE85L,F) is also resistant to humidity, temperature, and chemicals, making it especially well-suited for industrial applications.

The working principle of the DF3A3.3FU(TE85L,F) is fairly straightforward. Upon exposure to ESD and high voltages, the varistor element of the TVS diode effectively forms a short circuit between its two external electrodes, thus clamping the voltage at the diode\'s breakdown voltage. This prevents the surrounding components from being damaged by overvoltage transients. In normal operation, the TVS diode acts as an open circuit, providing no voltage drop and not affecting the normal operation of the circuitry.

Overall, the DF3A3.3FU(TE85L,F) is an excellent choice for applications requiring robust overvoltage protection in small form factors. It is relatively compact, with fast response time and wide operating temperature range, while providing excellent power clamping capabilities. Its small size and low profile make it perfect for applications with space restrictions. Furthermore, its resistance to temperature, humidity, and chemicals make it suitable for use in a variety of industrial applications.
