CZRFR52C18

The CZRFR52C18 is a Zener single diode that provides a high level of electrical and thermal stability, enabling a variety of applications. It has an excellent temperature performance, with a maximum adjustment of 0.3%/◦C that enables it to be used in precision voltage regulation, reference source, and temperature compensation circuits. Its operating temperature range is -55 to 175◦C. This diode is commonly used in various applications where the diode’s electrical and thermal stability, is necessary, such as transient suppression and LED illumination.

The CZRFR52C18’s construction features a single, conventional Zener diode with a gold metallization on the anode side and a metallized cathode for reliable electrical contact. The diode is housed in a hermetically sealed, two-pin ceramic package. This package has integrated leads which are designed for maximum mechanical stability, preventing any ingress of moisture, oxidation, and foreign objects from entering the pins and compromising the circuit’s performance. The package also has a small electrical saturation voltage, so the diode has a good heat sink capability and can accept higher loads.

In terms of working principle, the CZRFR52C18 diode is a depletion mode device, meaning it requires an applied voltage in order to operate. In this type of diode, a continuous flow of current runs in both directions near the diode’s operating temperature range. When applying a voltage, the applied voltage shifts the electrons and positively charged holes at the junction region which increase the charge current, resulting in a zero-voltage nonconductive region. This zero-voltage region helps maintain a stable voltage. As a result, the diode can handle voltage conditions from 0.2 to peak reverse voltage safely.

The maximum reverse voltage capability of the CZRFR52C18 diode is 52 volts and the forward current is up to 18 amperes. It is capable of dissipating up to 225W of power at its maximum load. The diode has a low leakage current and a low junction capacitance, which makes it well suited for use in high-speed switching applications. It is also capable of supplying a regulated voltage when used in voltage regulating circuits.

The CZRFR52C18 single Zener diode is a versatile device that is suitable for use in a wide range of applications. It has excellent electrical and thermal stability, a wide operating temperature range, and a high-power capability. It benefits from a reliable gold metallization and a hermetically-sealed ceramic package with integrated leads. These features make it an ideal choice for use in circuits that require a reliable reference source or transient suppression.
