CZRT55C2V4-G

CZRT55C2V4-G is a diode-type voltage regulator device with single Zener in a SOD-323 package. It is an ultra-small SOD-323 sandbar low voltage zener diode designed for voltage regulation, as well as for protection from over-voltage, over-current and electrostatic discharges. The CZRT55C2V4-G uses a Zener diode to protect against over-voltage and over-current conditions, providing optimal stability and ensuring high accuracy over a wide operating temperature range and transient response time.

The CZRT55C2V4-G is ideal for use in hard-to-reach areas in space-constrained applications such as portable and embedded electronics, PCs, and other consumer electronics, to provide over-voltage and over- current protection. It is also suitable for a variety of energy-saving solutions including LED lighting, automotive, solar and industrial systems as well as telecom equipment.

CZRT55C2V4-G also features low capacitance and low power consumption. It operates in a wide range of temperature and voltage conditions, making it suitable for a variety of temperature and voltage sensitive applications such as motor control and power management. It is specially designed to suppress the noise and resonance that accompanies the oscillation of voltage-regulation circuits and pulse generators.

The CZRT55C2V4-G works on the principle of Zener breakdown. The Zener breakdown is an electrical phenomenon that occurs when the voltage applied across a ceramic PN junction diode exceeds its reverse breakdown voltage. When the PN diode is subjected to a large enough reverse bias voltage, a large current begins to flow, leading to breakdown. The process of Zener breakdown creates a tunnel of current flow from the P region to the N region. This creates a low-voltage, low-resistance path for current to flow, even after the applying power is removed.

In the context of the CZRT55C2V4-G, this process is used to regulate the voltage applied across a particular resistor. When the voltage exceeds the breakdown voltage of the Zener diode, the Zener breakdown takes place and this regulates the voltage by dissipating the extra energy as heat. This helps in regulating the voltage applied to the device, thereby protecting it from the effects of over-voltage and over-current.

The CZRT55C2V4-G is a highly reliable and robust device with an operating temperature range up to +150 C. It is designed to protect sensitive devices against over-voltage/over-current conditions for a wide range of voltage and temperature applications. Its ultra-small SOD-323 sandbar package is ideal for use in space-constrained applications, making it ideal for a variety of consumer electronics, medical and automotive applications.
