Diodes are an essential element of numerous electrical and electronic applications, ranging from very simple rectification of AC power to complex circuits responsible for the control of high-voltage and large-current systems. Zener diodes, as a subset of diodes, are designed to allow voltage control over a range of currents. The BZV49-C68,115 is a single Zener diode specifically designed to provide efficient and accurate voltage regulation over a range of currents.

Description

The BZV49-C68,115 is a single Zener diode with a maximum power rating of 150mW. It has a breakdown voltage of 6.8V and presents a nominal zener impedance of 115 ohms. It also operates at a reverse voltage of 6.8V and has a Power Dissipation at Temperature Rise of 150mW. The device is composed of an anode, a cathode and a body that encases a junction. The junction is designed to create a potential barrier between the cathode and anode made of silicium and doping processes.

Applications

Due to its low leakage current, wide operating temperature range and low zener impedance, the BZV49-C68,115 finds a great number of applications. It is commonly used for the purpose of voltage regulation in power supplies, voltage references, voltage clamping and noise reduction. Other areas where BZV49-C68,115 is utilized include RF switching applications, transceiver voltage regulation and computer peripherals.

Working Principle

A typical diode relies on a pn-junction to function, while a Zener diode utilizes a reverse biased pn-junction to conduct current. The breakdown voltage of the BZV49-C68,115 is usually specified as 6.8V when it is operating at a nominal current; the Zener voltage increases or decreases according to changes in current. Whenever the total loading current on the BZV49-C68,115 is lower than its recommended breakdown current, the device acts as a normal diode which prevents the current from flowing through Zener junction resulting in its reverse breakdown. When in operation mode, the BZV49-C68,115 develops a flat pinch-off voltage that is precisely equal to the specified Zener breakdown voltage.

Conclusion

The BZV49-C68,115 can easily be implemented into an electronic circuit and it is highly reliable and efficient. It is able to operate in temperatures ranging from -50 to +200°C, thus providing users with the versatility they need in all sorts of projects. Its low leakage current and wide operating temperature range make it suitable for all sorts of applications. This Zener diode is commonly used for voltage regulation, voltage referencing, voltage clamping and EMI/RFI noise reduction.
