1N4749A-TP Diodes - Zener - Single

Zener diode is a type of diode whose characteristics are tailor-made for voltage regulation. Zener diode is a kind of two-terminal, nonlinear voltage-regulation component that utilizes the fact that when a current flows into one end of a junction (the zener diode anode terminal), a voltage is produced across the junction. When the voltage across the junction reaches the breakdown voltage of the diode, a large current flows, allowing it to regulate the voltage.The 1N4749A-TP is a 1.8W zener diode. It is a 5.6V, 500mW (500mW maximum power dissipation) device and has a maximum reverse leakage current of 50μA. It has a tolerance of ±5%, and a reverse voltage of 5.6V. The 1N4749A-TP is suitable for applications such as DC/DC and AC/DC converters, electronic circuits, and line regulation.The operating characteristics of a 1N4749A-TP are as follows. It may be operated over a wide range of current, with a maximum current of 150mA and a one-second pulse of up to 500mA. The reverse voltage of the device (Vr) can range from 0V-5.6V. The breakdown voltage of the device (Vz) is between 5.1V and 6.3V, with a typical value of 5.6V. The power dissipation is 500mW maximum. The capacitance of the device is 5-6pF (typical).The main purpose of the 1N4749A-TP is to provide a regulated voltage source to electronic circuits, DC/DC and AC/DC converters and voltage stabilizers. It prevents power fluctuations by providing a constant voltage supply to an electronic circuit. When used in an AC circuit, the 1N4749A-TP acts as a voltage regulator as it prevents overvoltage surges. It also helps in providing line noise rejection and circuit feedback. In addition, the 1N4749A-TP is used in series and shunt regulation, switch mode power supplies, photovoltaic and other isolators, and other regulated voltage sources.In terms of working principle, the 1N4749A-TP works by utilizing its PN junction in the form of a zener diode. The zener diode has two surfaces, the anode and cathode, and a junction between them known as a depletion region. When the current passes through the diode, it creates a potential barrier between the anode and the cathode. This potential barrier allows only certain electrons to pass and regulates the voltage. When the voltage applied to the 1N4749A-TP exceeds the breakdown voltage of the diode, the reverse current flow increases. This in turn increases the power dissipated in the diode and reduces the voltage across it, enabling voltage regulation.In conclusion, the 1N4749A-TP is a 5.6V, 500mW zener diode suitable for a wide range of applications such as DC/DC and AC/DC converters, electro-mechanical equipment, line regulation and other regulated voltage sources. It utilizes the PN junction to regulate voltage, allowing a constant voltage supply to be provided to an electronic circuit. By utilizing its operating characteristics such as wide range of current, maximum current of 150mA and maximum reverse leakage current of 50μA this component offers precise voltage regulation.
