The CLL4749A TR is a single Zener diode, manufactured by Comchip Technology. Its main application fields and working principles will be discussed in this article. The CLL4749A TR is a single Zener diode and has a broad range of applications, from general-purpose signal conditioning to signal amplification. This diode can be used in television and radio receivers, audio amplifiers and audio equalizers, oscilloscope pre-amplifiers and signal amplifiers, AC adaptors and switch-mode power supplies, electric motor control, and high-frequency switching circuits. In electric and electronic circuits, a Zener diode provides a direct, rectified current to a load, disregarding voltage fluctuations. This diode acts as a regulating element and performs a variety of critical functions, such as surge protection, over-voltage protection, current stabilization, voltage stabilization, and voltage limiting.The CLL4749A TR Zener diode is a two-terminal component with a breakdown voltage of 4.7 volts and a 5.8W power dissipation rating. It operates between -20°C and 80°C and features a 5% tolerance rating. The maximum reverse current is 0.3mA, and the forward current is 49mA with a capacitor and 78mA without a capacitor. Its small size makes it easy to install in confined areas or in large circuits, while its wide operating temperature range makes it suitable for a broad range of applications.The working principle of the CLL4749A TR is simple. When the correct voltage is applied to the diode\'s terminals, an electric current passes through the diode, thereby allowing a signal to be transmitted from one point to another. If the voltage exceeds the breakdown voltage of the diode, a breakdown current is generated, which passes through the diode instead of the load. This is called a clamping or stabilizing effect, and keeps the voltage from rising above the breakdown voltage.The CLL4749A TR Zener diode is a versatile and dependable component, suitable for a wide range of applications that require precision and reliability. Its low forward drop and low reverse current make it an ideal choice for signal conditioning and signal amplification, while its wide operating temperature range makes it well-suited for a range of temperature-sensitive applications. Furthermore, its small size makes it suited for use in cramped areas or large circuits. It is an excellent choice for a variety of voltage-dependent tasks.
