Advantages Compared with Other Transient Suppressors


1. Better Thermal Properties
A silicon suppressor has only one P-N junction to handle the current, but varistor has millions of P-N junctions to offer better
energy dissipation capability and peak current handling capability.
 

2. Speed of Response
The action of varistor is similar to that of other semiconductor devices, and its conduction happens very fast (nanosecond
range). In other words, varistor is fast enough to response to any practical requirements.
 

3. Stable Clamping Voltage over Temperature
Beyond the breakdown point, the clamping voltage of varistor is almost constant over wide range of operating temperature
while the clamping voltage of zener diode is higher at upper operation temperature. Even though leakage current of varistor
increases following the rise of temperature, its clamping voltage is temperature independent.
 

4. Capacitance
Compared with zener diodes, varistors have higher capacitance. Depending on the application, transient suppressor
capacitance can be a desirable or undesirable feature. In DC circuits, the capacitance of varistors provides both decoupling
and transient voltage clamping functions.
 

5. Less Expensive
Compared with diodes, varistor has small size and is cost-effective

 

Varistor Manufacturering Process

To ensure the highest performance and maximum reliability, tight on-line control is maintained in automated manufacturing techniques.The manufacturing process flow shows each step of the manufacturing process and clearly demonstrates the importance attached to on-line control.Each major step of the manufacturing process is described in the following sections:

 

MILLING AND MIXING
Incoming materials are checked, weighed, milled and mixed
for several hours to make a homogeneous mixture.


GRANULATION
A binder is added to produce larger granules for processing.


PRESSING
The surface area and thickness of the disc help to determine the final electrical characteristics of the varistor, therefore
pressing is a very important stage in the manufacturing process. The granulated powder is fed into dies and formed
into discs using a high speed rotary press.

 

Quality Assurance Process

 

1.Our company's varistors are delivered to users after being tested according to the following standards by our quality unit. The products should meet the technical characteristic indexes of corresponding type; the technical capacity of manufacturing the equipment and the precision of testing equipment should also meet the requirements. The following tests need to be tested to assure stable and high quality. Testing and purification of incoming raw materials 

 

2.Testing and purification of incoming raw materials 

The physical-chemical performances of all raw materials should be tested by required procedures. Some metallic oxide for producing varistors should be purified by our company's original purification technology. This assures the varistor's quality further.

 

3.Final test

We set quality controlled points in the technological process. The products should be tested after every techno-logical process. Meanwhile the production process control was estimated by the uninterrupted monitoring, testing and timely quality analysis.

 

 

Storage Conditions
