Diodes, or two-terminal rectifying devices, are amongst the most ubiquitous electronics components. One of the most widely used types of diodes is the Zener diode. Zener diodes are widely used as voltage regulators and voltage references in many applications. The 1N4465US is a single Zener diode with a maximum reverse voltage rating of 6 volts. In this article, we will look at the application fields of the 1N4465US, as well as its working principle.

Application Field

The 1N4465US Zener diode is well-suited for a variety of general purpose applications, such as voltage regulation, voltage reference and surge protection. It is particularly well-suited for use in low-voltage switched-mode power supplies, DC-DC converters, general-purpose linear supplies and voltage regulation circuits. Additionally, the 1N4465US can be used in low-voltage ripple filters, low-current applications, coupling and clamping applications, EMI/RFI filtering applications and surge protection applications.

Working Principle

The working principle of the 1N4465US Zener diode is based on the Zener breakdown principle. When the reverse voltage applied across the diode exceeds the Zener voltage or breakdown voltage, a large number of electron-hole pairs are generated due to the avalanche effect. This causes the reverse current through the diode to increase exponentially, while the voltage drop across the diode remains constant. This phenomenon is known as the Zener effect or Zener breakdown.

In operation, the 1N4465US Zener diode draws a small current and does not require an external series resistor for operation. The diode’s Zener voltage is 6V, with a maximum reverse current of 20mA. The 1N4465US has a maximum working temperature of 105°C, with a maximum power dissipation of 500mW. This makes it an ideal choice for low-voltage applications.

Conclusion

The 1N4465US Zener diode is a single Zener diode with a maximum reverse voltage rating of 6 volts. It is suitable for use in a variety of general-purpose applications such as voltage regulation, voltage reference and surge protection. The 1N4465US works on the Zener breakdown principle, in which the reverse voltage applied across the diode causes the reverse current to increase exponentially. The 1N4465US has a maximum working temperature of 105°C, with a maximum power dissipation of 500mW, which makes it an ideal choice for low-voltage applications.
