CLL5243B BK Application Field and Working Principle

The CLL5243B BK is a single Zener diode offering a low noise, high performance solution for power management applications. This low capacitance, fast recovery device typicallyoperates at 1.8V to 6V, enabling hyper-low-power operation in various applications. The CLL5243B BK is ideal for low voltage Zener diode applications in portable and low voltage electronic systems. It offers excellent noise performance and low leakage current when compared to general-purpose Zener diodes. The half-sine wave surge capability of the diode is also exceptional, allowing it to provide robust power supply protection. Beyond its voltage-referencing functionality, the device can also be used to provide reverse-polarity protection, hysterisis, and ultra-low voltage clamping in a variety of protected systems. The device is fabricated using a BK dielectric process and a CMOS chip fabrication technology for improved cleanliness and better die performance. The die is then tested and evaluated for reliability, endurance and stability. The CLL5243B BK is packaged in a variety of standard packages and is available in a wide range of sizes and configurations for use in a variety of design requirements. The CLL5243B BK produces voltage-referencing based on the Zener principle. When connected in a circuit and a breakdown voltage is exceeded, a small current will flow, enabling a voltage drop at the anode. This is then used to create a voltage that is set in the reference of the circuit. The special feature of Zener diodes is their ability to operate in both forward and reverse voltage directions, allowing the voltage drop to be used to clamp a signal to a specific level. This can be used to protect sensitive circuits from transients or over-voltage conditions. The CLL5243B BK has a low temperature coefficient, which gives it a high degree of accuracy for Zener diode applications. In stringent applications, such as low voltage circuits, the CLL5243B BK is the ideal solution. The device is also rated for a very high reverse leakage current at the breakdown voltage, reducing power consumption and allowing the device to handle current surges with minimal degradation. The CLL5243B BK has an operating temperature range of -40°C to +85°C, making it suitable for use in a variety of applications requiring extended temperature operation. It is also robustly rated, with its breakdown voltage and dynamic resistance rated for more than 18V at room temperature. It is also very reliable, possessing a minimum stability of 2.00V. The minimum storage temperature rating makes the CLL5243B BK suitable for use in demanding environmental conditions. Overall, the CLL5243B BK is an excellent example of a single Zener diode. It operates at a wide voltage range with a low-noise and high-performance package, making it ideal for powering and protecting a variety of low-voltage, portable and low-power electronic systems. It also offers excellent surge capability and low temperature coefficients, making it especially well-suited for use in low-voltage protection and voltage-referencing applications in hostile environments. The CLL5243B BK is available from many leading manufacturers in a variety of packages and configurations. The device is well-suited for a wide range of applications and is reliable and robust in operation. Engineers and designers should consider the CLL5243B BK for their voltage-referencing, reverse-polarity protection, and low voltage clamping needs.
