The 1N4736A diode is a single Zener diode, and is a type of diode used for voltage regulation. It is manufactured to meet the JEDEC standards for reliable and accurate electronic device performance, and is suitable for a variety of circuit designs. The 1N4736A is used primarily as a low-power series regulator in power supplies, as a voltage reference for current regulators, and as a protection device in circuits that need to be protected from dangerous voltages.

Overview

The 1N4736A diode has a breakdown voltage of approximately 5.1V, making it a suitable choice for low-power applications. It is constructed with a lead frame and an epoxy-filled, plastic body, which ensure a high degree of robustness, reliability and temperature stability. The 1N4736A diode provides a low-cost Zener diode option with a high degree of performance. The diode is typically used in many applications, including power supplies, voltage references, RF inductors and peak current protection.

Application Field

The 1N4736A diode is a popular choice for voltage regulation in power supplies. When placed in series with the main power supply and then connected to a load, it regulates the output voltage. This is particularly useful when using alternative sources of power, such as solar or wind, as the output voltage can vary when the alternative power supply is not perfectly reliable. The diode is also frequently used to create a reference voltage for current regulation, in circuits with multiple voltages, and to protect the circuit from spikes caused by a sudden increase in voltage.

Working Principle

The 1N4736A diode works by allowing current to flow in one direction while blocking it in the other. When the voltage is below the Zener voltage (Vz) the diode acts like an ordinary diode, allowing current to flow in the forward direction only. Once the voltage exceeds the Vz, the diode begins to conduct in the reverse direction, allowing the voltage across it to remain constant. This constant voltage is known as the Zener voltage and is used to regulate the output voltage of a power supply or protect a circuit from high-voltage spikes. By combining multiple 1N4736A diodes in series, the Zener voltage can be increased accordingly.

Conclusion

The 1N4736A diode is a single Zener diode designed for low-power applications. It is used in voltage regulation, voltage references and peak current protections, such as in power supplies and circuits with multiple voltages. The 1N4736A works by blocking or allowing current to flow in one direction, depending on whether the voltage is below or above the Zener voltage. It also allows for the Zener voltage to be increased by combining multiple diodes in series. The 1N4736A diode is an affordable and reliable choice for a variety of circuit designs.
