CMOZ15V TR

CMOZ15V TR Application Field and Working Principle

The CMOZ15V TR is a general purpose ROHM Zenar diode, used as an active clamping device to suppress high-frequency noise and surge in various applications. It has a total maximum repetitive peak reverse voltage of 15V and a total maximum repetitive peak forward voltage drop of 1.1V. The device has a low forward voltage that is rated 0.85V, compared to the normal VF of 0.7V. The device offers excellent surge protection, low EMI, low reverse recovery time and low clamping voltage.

The CMOZ15V TR diode can be used in a variety of applications. It is commonly used as a clamping device (or Zener diode) in closed-loop feedback circuits, power regulator circuits, power switching circuits and high-frequency circuits. It can be used to protect against reverse voltage by clamping the voltage to a predetermined safe value. The device also acts as an EMI filter to minimize the amount of noise or interference that is radiated or conducted from the system. It can be used as a switching diode in high current switching applications and pulse applications.

Working Principle

The CMOZ15V TR provides excellent overvoltage protection for a wide range of applications. The device clamps the voltage to a safe level when there is a large voltage spike or a negative voltage, preventing the system and the components from being damaged. The device works by having a built-in Zener diode that protects the power supply and the downstream components from overvoltage and overcurrent. The Zener diode increases the voltage level at the drain of the diode, so that any spikes in the supply voltage are clamped at this higher level.

The device acts as an active clamping device that clamps the voltage at a safe level to protect the downstream components. This is done by applying a reverse bias to the diode which turns it on and increases the voltage at the drain of the diode. The device also provides excellent EMI protection by suppressing high-frequency interference. It acts as an EMI filter by providing a low impedance path to ground at the device’s terminals.

Conclusion

The CMOZ15V TR is a general purpose ROHM Zenar diode, designed to provide a wide range of protection against overvoltage, overcurrent and EMI. The device is designed to clamp the voltage to a safe level when there is a large voltage spike or a negative voltage. It also provides EMI protection by acting as an EMI filter. The device is used in a variety of applications, including closed-loop feedback circuits, power regulator circuits, power switching circuits and high-frequency circuits.
