1N4698 (DO35)

1N4698 (DO35) Application Field and Working Principle

The 1N4698 (DO35) is a commonly used single Zener diode produced by several semiconductor manufacturers. They come in two different configurations: a 3. 3 V forward voltage (V_F) and a 3. 6 V forward voltage (V_F). The maximum power dissipation for the 1N4698 (DO35) is 500mW, with a maximum junction temperature at 150°C (T_J).

Application Fields

The 1N4698 (DO35) has several applications. The most common among them are voltage regulation, voltage limiting, and power supply protection. It can also be used as a clamping diode or a Zener switch. Due to its small size, the 1N4698 (DO35) is commonly used in portable devices.

Working Principle

The 1N4698 (DO35) works by allowing current to flow in one direction only, thereby maintaining a regulated voltage. When the voltage reaches a certain limit, the diode will start conducting, preventing further increase in the output voltage. This limits the amount of current that can pass through the diode and hence the output voltage. In addition, it has a certain voltage drop across it, which acts as a limit to the maximum output voltage. This ensures that the output is kept within acceptable limits.

When the voltage drops below the diode\'s breakover voltage, however, the diode starts conducting again and no longer limits the current. As a result, the maximum output voltage can be kept in check. This property is what makes the 1N4698 (DO35) ideal for applications such as voltage regulation and power supply protection.

Conclusion

The 1N4698 (DO35) is a single Zener diode commonly used for, but not limited to, voltage regulation, power supply protection and voltage limiting. It has a 3.3 V forward voltage and a maximum power dissipation of 500mW. It works by allowing current to flow in one direction, preventing the output voltage from reaching too high and protecting the power supply in the process.
