Introduction

The CLL4735A BK diode is a single Zener diode with a breakdown voltage of 18V. It is part of the CLL Series, a series of high-speed, low-power Zener diodes produced by Diodes Incorporated. The CLL Series has a wide range of breakdown voltages, from 5V to 200V. The CLL4735A BK diode has a maximum reverse current of 3mA, a maximum power dissipation of 1W, and a maximum toggle frequency of 10KHz. It is available in a small, easy to mount SOT-23 package, with a maximum operating temperature of 150°C.

Application Fields

The CLL4735A BK diode is most commonly used in consumer electronics and automotive applications. It is used as a reference and protection diode, to regulate an unregulated source to a constant voltage and protect components from overly high voltages. It is also commonly used as a voltage clamping and overvoltage protection device. Its high speed and low power make it an ideal choice for these applications. Other applications for the CLL4735A BK Zener include radio frequency shielding, RC oscillator circuits, voltage clamping circuits, flyback diodes, and power switching circuits.

Working Principle

The CLL4735A BK diode is a single Zener diode, which is a diode that is designed to break down at a predetermined voltage and dissipate current. Unlike a normal diode, the CLL4735A BK will allow current to flow even if the voltage across it is higher than its reverse breakdown voltage. This is because when the voltage across the diode reaches the Zener voltage, it will begin to conduct and dissipate a large amount of current. When the reverse voltage across the CLL4735A BK is below the Zener voltage, the diode acts like a regular diode and limits the current to a specified amount (in this case, 3mA). When the reverse voltage exceeds the Zener voltage, the diode will begin to break down and dissipate current. This current is known as the Zener current, and it is proportional to the amount of voltage applied.

Conclusion

The CLL4735A BK diode is a single Zener diode with a breakdown voltage of 18V. It is used in many different applications, including consumer electronics, automotive, and radio frequency, as well as voltage clamping and overvoltage protection. The diode is designed to break down at a predetermined voltage and dissipate current. When the reverse voltage across the CLL4735A BK is below the Zener voltage, it acts as a regular diode and limits the current to a specified amount. When the reverse voltage exceeds the Zener voltage, the diode begins to break down and dissipate current.
