Diodes are semiconductor devices that allow electricity to flow in one direction. Zener diodes are special types of diodes that allow both directions of current flow, but with different voltages. The 1N4108 (DO35) is a type of Zener diode. It has a maximum voltage of 200 volts and a maximum current of 500 mA. This article will explain the application fields and working principle of 1N4108 (DO35).

1N4108 (DO35) has many application fields. It is commonly used in voltage regulator circuits and as a switching element in power supplies and logic circuits. It is also used as a surge protector in circuits where high voltage transients may occur. 1N4108 (DO35) can also be used as a voltage reference in low voltage circuits, such as switching regulators and linear regulators. Furthermore, it can be used in temperature sensing and temperature compensation circuits, as well as in voltage protection circuits.

1N4108 (DO35) is a PN junction diode and has two terminals, the anode and the cathode. The anode is the positive terminal and the cathode is the negative terminal. When forward biased, the diode allows current to flow from the anode to the cathode. When reverse biased, no current flows. As the reverse voltage is increased, the diode starts to conduct a small current, known as the “Zener breakdown voltage”. This voltage is determined by the doping level of the semiconductor material. The maximum allowable forward and reverse current of the 1N4108 (DO35) diode is 500 mA.

1N4108 (DO35) diodes work best in a temperature range of –65°C to +175°C. The Zener voltage of this type of diode is not temperature dependent. However, the diode can be damaged by excessive temperatures and reverse voltages. 1N4108 (DO35) is a relatively low power device and is best used in low voltage applications. For higher voltage applications, higher power Zener diodes should be used.

In summary, the 1N4108 (DO35) is a PN junction diode that allows both forward and reverse current flow. It has a maximum voltage of 200 volts and a maximum current of 500 mA. 1N4108 (DO35) is commonly used in voltage regulator circuits, switching elements, surge protection circuits and low voltage reference circuits. It works best in a temperature range of –65°C to +175°C. It is a relatively low power device and should be used for low voltage applications only.
