TVS - Diodes

Transient Voltage Suppressors (TVS) are a class of general-purpose diodes that are designed to protect electrical systems from voltage spikes and transients. They use semiconductor materials such as silicon, germanium, and indium to limit the voltage and current entering a system. The BZG04-120TR is a member of the TVS-Diode family and is designed to protect sensitive electronics from electrical surges.

BZG04-120TR Application Field

The BZG04-120TR is a transient voltage suppressor (TVS) diode designed specifically for protection against overvoltage threats. It is applied across a variety of electronic systems such as industrial robots, automobile engines, power supplies, and other sensitive components. It is suitable for use in automotive, medical, telecommunications, and consumer electronic applications

BZG04-120TR Working Principle

The BZG04-120TR is an unidirectional device with two terminals and no exposed metal, allowing it to be applied in a broad range of applications. When a transient voltage exceeds the threshold of the TVS diode, the device starts to conduct current and the voltage is clipped. This results in device overheating and current being absorbed by the device before it can damage connected circuits. The BZG04-120TR also features peak voltage protection, which allows it to absorb any residual energy left over from the transient to prevent further damage.

BZG04-120TR Characteristics

The BZG04-120TR offers a maximum rated surge voltage of 400 V, a clamping voltage of 536 V, and a maximum peak pulse current of 120 A. It has a low dynamic resistance of 0.45 Ω. The device is designed to handle temperatures ranging from -55°C to 85°C. It has a maximum power dissipation of 4.7 W and a capacitance of 22 pF.

Conclusion

The BZG04-120TR is a robust, highly efficient transient voltage suppressor (TVS) diode with an impressive array of features for greater protection against overvoltage. It is easy to install and offers excellent protection against voltage spikes and transients. It is ideal for use in various industrial and automotive applications where reliable protection is a must.
