The BZX84C47-G3-08, a single Zener diode, is a reliable and crucial component to many modern devices, with many applications ranging from circuit protection to level shifting. This diode’s details are often found on circuit data sheets as designers find this device helpful in their designs.

Construction & Operation

The BZX 84C47-G3-08 is constructed like any other diode and operates with a doped p-n junction. This junction acts as a sort of gate between the two sides of a circuit, allowing current to flow in one direction, but blocking it in the opposite direction. The construction is meant to take advantage of the diode’s unique properties in order to facilitate circuit needs.

The Zener Voltage Rating

What differentiates the BZX 84C47-G3-08 from other diodes is its Zener voltage rating, which is a measure of the reverse bias voltage necessary to enable this diode’s Zener effect. This Zener voltage rating is an incredibly important factor in many diode applications, and is especially important for this diode, because it determines the diode’s breaker voltage, reverse bias current, and Zener breakdown voltage.

Applications

The BZX 84C47-G3-08 can be used in a variety of applications, however the most common applications are within circuit protection, level shifting, and voltage regulation. In regards to circuit protection, this diode is placed in a circuit and set to a certain voltage such that it operates at a higher voltage than the operating voltage of the circuit. When this happens, the diode will block current from passing through the circuit, protecting components susceptible to large voltage or current swings.

The BZX 84C47-G3-08 is often used in level shifting applications as well. As electronic components grow smaller and more integrated, the voltage supplies necessary to run them also shrink. This diode can be applied to a circuit so that it can take a larger voltage on one side of the diode and scale it down to the desired voltage on the other side. This allows for much simpler designs without the necessity of sophisticated voltage regulators.

The BZX 84C47-G3-08 can also be used to create a stable voltage source. This usually requires the application of multiple Zener diodes. The diodes are organized such that they act in parallel while still keeping the Zener voltage rating of the diode intact. This allows the designer to have greater control over the voltage produced by the circuit, even in environments with fluctuating voltage levels.

Conclusion

The BZX 84C47-G3-08, while a simple device, contains capabilities invaluable to modern circuits. Its Zener voltage rating grants both circuit protection and level shifting capabilities, making it an incredibly useful device for a variety of circuits. On top of this, its ability to be used in stable voltage sources allows for improved voltage control in many applications. The BZX 84C47-G3-08 is simply a must for any designer’s toolkit.
