The 1N5272A (DO-35) is a type of Zener diode that is single. It has various application fields and one of its most common applications is to regulate voltage in a circuit. Zener diodes are built to have negative resistance, under certain conditions, and are used as voltage regulators in many electronic circuits. Specifically, this diode is designed specifically for low power, high impedance applications where stability is important.

The 1N5272A has a maximum power dissipation of 0.5 watts (at 25°C) and a maximum breakdown voltage of 5.2 volts. It uses silicon chips and has a reverse current of 100 microamps (at a temperature of 25°C). It has a voltage regulator tolerance of 5%, so it provides a stable output voltage.

The working principle of 1N5272A is based on Zener breakdown, which happens when electric current flows in the reverse direction and voltage across the diode’s anode and cathode increases more than the rated breakdown voltage. This results in a high voltage drop across the diode and a spike in the current. This current then increases the electric field in the junction, which causes more electrostatic charges to form and create a current flow.

The main function of 1N5272A is to regulate voltage and provide a stable electrical current in electronic circuits. It is typically used to provide a steady voltage supply to transistors and integrated circuits. The diode can also be used to protect circuits from voltage surges and spikes. It is used as a voltage supervisor or overvoltage protector in many applications, such as a battery tester, field-effect transistors, and driver circuits.

When using 1N5272A, it is important to keep in mind that the diode has a voltage coefficient of -2.2mV/degC, which means the breakdown voltage will vary with temperature. It is also important to make sure the diode is mounted on a suitable heat sink, since it can dissipate a large amount of heat.

The 1N5272A (DO-35) is a versatile Zener diode that can be used in many different applications. It can provide a stable voltage output, protect circuits from overvoltage, and provide a surge protection for transistors and integrated circuits. Additionally, its low power requirements and high current capability make it a great choice for low power, high impedance applications.
