CRD in parallel
The use of CRD in parallel increases their current
handling capabilities.
The compensation of current reduction due to self
heating
Placing resistors in parallel with CRD can correct
any current decrease when the applied voltage
increases. The following values are typical for
correction resistors.
Compensative resistor is not necessary if the
current value is less than 1 mA.

Increasing the voltage range using a zener diode
Connecting zener diodes in series with the line ensures
that the current is constant in high-voltage area.
