Introduction to 1N4104URThe 1N4104UR is a single, unmarked, unidirectional diode, meaning that current flows only in one direction. It has a Zener work function, which means that it acts like a voltage regulator in a reverse-biased state. Under a minimum of reverse voltage, it will break down and conduct an avalanche current. This allows it to control the voltage to a specific level, independent of the current supplied. 1N4104UR Application Fields1N4104UR diodes are most often used in electronic circuits and systems in the design and production of electronic products. It can be used in Flyback transformers, AC/DC converters, audio amplifiers and other applications. It often appears in the primary and secondary voltage control of televisions, monitors, and other CRT displays, where the Zener work function helps protect delicate circuits from voltage spikes or brownouts.The 1N4104UR diodes are also used as reference or precision voltage regulators, as current limiting devices, and as overvoltage protection devices. These responsibilities can protect sensitive surface mount components from damage caused by unexpected voltage or current levels. 1N4104UR Working PrincipleThe 1N4104UR diode is designed to work in a reverse-biased state. This means that the anode of the diode is connected to the negative voltage source and the cathode is connected to the positive source. When a small reverse voltage is applied, a minority carrier’s diode will break down and allow a controlled reverse current. This ensures that the voltage across the Zener diode will be held at a constant value, independent of the current supplied.In order to prevent avalanche breakdown, the Zener diode exhibits a negative temperature coefficient. This is a characteristic of all Zener diodes and occurs when heat causes a decrease in the reverse breakdown voltage. This helps protect semiconductor devices from unexpected voltage levels.The 1N4104UR diode has a reverse power dissipation of 500mW, a maximum reverse voltage of 10V, and a high forward current capacity of addition to these features, the diode has a typical junction capacitance of 13pf. These features ensure that the 1N4104UR can be used in a wide range of applications.ConclusionThe 1N4104UR diode is a single, unmarked, unidirectional diode with a Zener work function. It is commonly used for voltage control, current limiting, and overvoltage protection. It is designed to work in a reverse-biased state and its reverse power dissipation is 500mW. Furthermore, it has a maximum reverse voltage of 10V and an high forward current capacity. The 1N4104UR has all of these features and is suitable for a variety of applications.
