Diodes are an essential component in almost any electronic system, and the unique properties of Zener Diodes make them valuable for applications where a low breakdown voltage is required, such as voltage regulation and voltage clamping. The CD0603-Z33 is a single Zener Diode designed to fit in a surface mount package of CHIP SCALE 0603 [1.6mm x 0.8mm].

The CD0603-Z33 has a nominal Zener voltage of 3.3 volts and a maximum Zener current of 5.8 mA. The maximum Zener impedance is specified as 50 ohms, which is the equivalent of a maximum equivalent series resistance (ESR) of 50 ohms. In addition, the diode has a maximum reverse leakage current of 3.2 µA.

The working principle of this diode is the same as other Zener Diodes. Zener Diodes are specially designed so that when a certain amount of reverse bias voltage is applied to the diode, it begins to leak current. This current flow is not linear and increases exponentially with voltage, allowing for a very tight voltage regulation for a given load.

The CD0603-Z33 has a low reverse leakage current and maximum Zener impedance, making it ideal for applications requiring a small voltage reference with tight regulation under varying conditions. Applications include voltage references, clamping circuits, overvoltage protection circuits, and resettable circuits.

The CD0603-Z33 also has a wide range of operating temperature, from -55°C to +150°C and has a storage temperature of -40°C to +125°C, making it suitable for use in extreme conditions. It also has a mean time of failure (MTBF) of 40,000 hours at +85°C, ensuring the diode maintains reliable operation over long periods of time.

The CD0603-Z33 has passed the ESD-test (Electrostatic discharge) and is RoHS compliant. It is widely used in various applications where low voltage regulation is needed and comes in a compact CHIP-SCALE package.

In conclusion, the CD0603-Z33 is a popular single Zener Diode with a low breakdown voltage, low reverse leakage current, high Zener impedance, wide operating temperature range and a long MTBF. Its small surface mount package and ability to withstand extreme temperatures make it suitable for many applications, including voltage references, clamping circuits, overvoltage protection circuits and resettable circuits.
