CMDZ5248B BK is a single Zener diode device. It is widely used in applications such as voltage regulation, surge suppression, and low-level rectification.

Package

CMDZ5248B BK comes in a miniature single in-line package (SIP) with a maximum size of 4.3 mm x 4.3 mm.

Features

CMDZ5248B BK features a high voltage tolerance, low leakage current and fast response times. It also has a wide range of operating temperatures and excellent stability over time and temperature.

Applications

CMDZ5248B BK is used in applications such as voltage regulation, surge suppression, and low-level rectification. These applications require a device to reduce the amount of input voltage and maintain a specific level of voltage at the output, even when the load on the device is changed. This can be achieved by the use of a Zener diode, which provides a highly accurate and efficient way to regulate the voltage while providing protection against overvoltage.

CMDZ5248B BK is also used in power electronic converters where a single diode can provide protection for the components. This type of diode can also be used as a transient-protection device in battery systems, providing protection against overvoltage and reverse polarity.

Working Principle

The working principle of the CMDZ5248B BK is based on the Zener effect. The Zener effect occurs when an electric field is applied to an already existing reverse-biased p-n junction, resulting in a breakdown of the reverse-biased p-n junction. The breakdown occurs when the applied electric field is strong enough to cause a tunneling effect across the junction and allows current to flow in the reverse direction to the original bias. This current is known as the Zener current and it is used to regulate the output voltage of the device. The Zener voltage is critical to regulate the output voltage as any change in the Zener voltage will affect the output voltage.

The CMDZ5248B BK features low reverse leakage current (<1 uA) and up to 1-kV breakdown voltage. The device also features a high temperature operating range from -55°C to +150°C.

Conclusion

CMDZ5248B BK is a single Zener diode device which is used in applications such as voltage regulation, surge suppression, and low-level rectification. It has a wide range of operating temperatures, low reverse leakage current, and a maximum breakdown voltage of 1-kV. The device works on the principle of the Zener effect, where a tunneling effect occurs through a reverse-biased p-n junction and allows current to flow in the reverse direction. This current is known as the Zener current and is used to regulate the output voltage of the device.
