CZ5345B TR

The CZ5345B TR is a single Zener diode, typically used in applications where voltage regulation, dynamic impedance matching, impedance adaptation, and noise reduction are required. The device is available with a peak reverse voltage of 5.2V and a peak forward current of 0.7mA. It has a typical dynamic impedance (dynamic resistance) of 2.3Ω, a capacitance of 6pF, and a breakdown voltage of 5.2V.

Application Fields

The CZ5345B TR is typically used in applications where precise voltage regulation is required. Examples include DC-DC converters, automotive electronics, radio communications, and high-frequency switches. This device can provide precise regulation in applications such as voltage monitoring, rectification, and power-supply protection circuits. The device is also well suited for filtering and buffering applications.

Working Principle

The CZ5345B TR is a Zener diode, a type of diode that conducts current in one direction (forward) and blocks current in the opposite direction (reverse). When a sufficient reverse voltage is applied to the diode, it will break down and become conductive. This breakdown voltage is its rated peak reverse voltage. When the voltage increases to the regulated voltage level, current passes through the Zener diode; this is known as reverse breakdown. At this point, the voltage across the diode remains constant, allowing the diode to regulate the voltage.

The CZ5345B TR also provides protection against reverse currents since it blocks current in the reverse direction. This protects other devices in the circuit from damage due to excessive current. In addition, the CZ5345B TR can also be used to provide impedance matching and noise reduction in applications that require precise voltage regulation.
