MMBZ5245C-G3-08 is a single Zener diode manufactured by ON Semiconductor that can be used in variety of applications as an efficient means to protect circuits from overvoltage transients, as well as regulate voltages in secondary circuits.

Application fields

MMBZ5245C-G3-08 has wide range of use, it can be used in telecommunications, power system protection, instrumentation and many other fields.

MMBZ5245C-G3-08 is ideal for secondary circuit protection that operates on AC voltages since it has built-in avalanche capability. It can be used as a voltage reference in switching applications as well as for voltage isolation and voltage clamping applications.

Working mechanisms

MMBZ5245C-G3-08 works on an avalanche mechanism which has the ability to clamp the voltage to a specific level. This voltage level can range from 3.3V up to 63V.

MMBZ5245C-G3-08 has a low-voltage VZ rating which is equal or greater than 5V. It also has a high-current IZT rating which can be as high as 1000mA.

When used in a circuit, MMBZ5245C-G3-08 can protect components from overvoltage transients by clamping the voltage at the avalanche voltage level which is the VZ rating. Once the voltage reaches the avalanche voltage level, the current flowing through the diode will decrease and the diode will no longer be able to carry the current.

The Zener diode can also be used for voltage regulation in a circuit by having the Zener diode across a resistor. The voltage drop across the resistor will cause the current flowing through the diode to decrease, thus decreasing the voltage at the node.

Conclusion

In conclusion, MMBZ5245C-G3-08 is an ideal choice for secondary circuit protection, voltage regulation and other circuit protection applications due to its low-voltage VZ rating, high-current IZT rating and avalanche capability.
