CMOZ27L TR

Diodes - Zener - Single - CMOZ27L TR Application Field and Working Principle

The CMOZ27L TR is a low-cost, low-power diode in the Zener diode family. It is designed to provide a low forward voltage drop and low reverse leakage. This diode is available in a variety of package styles, including surface mount, through-hole, and axial lead configurations. The device provides consistent and reliable performance in a wide temperature range.

The CMOZ27L TR is primarily used for voltage regulation and voltage reference in a variety of applications. It can also be used in rectifiers, switching applications, and as a back-up protection or surge protection device. The CMOZ27L TR also provides ESD protection.

The CMOZ27L TR has a maximum reverse breakdown voltage of 27 V, with a tolerance of ±5%. The device also has a forward current capacity of up to 50 mA. It has a very low forward voltage drop of 0.2 V at 25°C, making it ideal for low-power applications. The maximum power dissipation is 500 mW at 25°C. The device can operate up to a temperature of 175°C.

Working Principle

The CMOZ27L TR operates on the principle of reverse working as a zener diode. When forward biased, the diode passes current from anode to cathode but, when reverse-biased, current is blocked until it reaches the breakdown voltage, at which point it starts to conduct.

When reverse biased, most of the voltage appears across the zener diode, resulting in a constant voltage drop. If a current passes through the diode, it will begin to heat up, which in turn increases its resistance and thus its forward current. This is known as the zener effect and is used to maintain a constant voltage drop.

In applications requiring a regulated power supply, the CMOZ27L TR can be used to create the desired output voltage. With the help of a current-limiting resistor, a stable voltage output can be achieved. The CMOZ27L TR can also be used in switching applications, such as switching between power supply levels or load sources.

Conclusion

The CMOZ27L TR zener diode offers low forward voltage drop and low reverse leakage, and is suitable for a wide range of applications, including voltage regulation and voltage reference, rectification, switching, surge protection, and ESD protection. Its low power dissipation and temperature stability make it an ideal choice for low-power applications.
