Operating Temperature Range

The following values for the operating voltage (same as power dissipation or energy absorption) are admissible in the temperature range from - 40 °C to + 85 °C.

For other ambient temperatures, the values for the maximum operating AC or DC voltage must be reduced as shown.

The graph illustrates the derating of the maximum operating voltage subject to the operating temperature in %.

Technical Data

The values in the table below are absolute limits.

The maximum protection level is related to the class current.

The class current is the peak value of current which is 1/10 of the maximum peak current for 100 pulses.

U / I Characteristic: Series 10M

The characteristic curve is showing the maximum possible voltage at a specific current.

The typical voltage values lie below it.

 

 

Pulse Diagram

If the permissible surge current of another pulse length (at a  fixed number of pulses) cannot be found in the table, please refer to the diagrams.

The graph shows permissible surge current as a function of the number of surges and the pulse length.
