Diodes - Zener - Single

Zener diodes are heavily used in a number of different applications. The CDLL5917B is a single Zener diode designed and manufactured using planar technology. This allows for a much more reliable product than with an older Zener diode. The CDLL5917B is primarily used in applications requiring ESD protection, voltage clamping and current limitation.

Applications

The CDLL5917B is used in a variety of applications, the main ones being ESD protection, voltage clamping, and current limitation. In ESD protection, the Zener diode will clamp any incoming voltage that is above a certain threshold. This prevents power spikes from damaging delicate electronics. This Zener diode is ideal for ESD protection, as it is able to withstand up to 25kV simultaneously.

The second application for this device is for voltage clamping. This allows for a fixed output voltage, regardless of input voltage. This makes this a very useful device for stabilizing an AC source, or for a constant source of voltage for a load. The CDLL5917B is able to regulate the voltage over a range from 3.3 V to 5.6 V.

The third main application is current limitation, which helps protect electronics from drawing too much power. The Zener diode acts as a resistor, limiting the current. This is useful in applications such as power supplies, where power surges and overloads can be damaging.

Working Principle

Zener diodes operate on a principle known as reverse breakdown. Under normal operation, a diode will block the flow of current with the reverse bias voltage below a certain threshold. In the case of a Zener diode, however, the voltage threshold is lowered, allowing the current to pass through the diode. This current is limited by the Zener diode, and it is also regulated, ensuring that the output voltage is constant.

The CDLL5917B is a single Zener diode and contains two separate terminals. One is the anode, which connects to the power source, and the other is the cathode, which connects to the output. The energy from the power source flows through the anode, into the diode. The diode then limits and regulates the current, and the output voltage is regulated at 3.3 V to 5.6 V.

Properties

The CDLL5917B has several useful properties, making it an ideal choice for a number of applications. For example, it is designed with low power consumption and low forward voltage, allowing for a more efficient power system. This device also has excellent thermal stability and a wide temperature range, allowing it to be used in extreme temperatures.

The CDLL5917B also has excellent ESD protection, withstanding up to 25kV ESD. This makes it ideal for use in applications where ESD can be a significant problem. Finally, this device is highly reliable and has a long life expectancy, due to its planar technology.

Conclusion

The CDLL5917B is a single Zener diode, designed and manufactured using planar technology. It is mainly used in applications requiring ESD protection, voltage clamping and current limitation. This Zener diode has excellent properties, including low power consumption, low forward voltage, excellent thermal stability and wide temperature range, ESD protection, and long life expectancy. The CDLL5917B is an ideal choice for a number of applications.
