CRD is a diode which supplies constant
current to an electric circuit, even when
power supply voltage fluctuations or load
impedance fluctuations occur.
CRD is used for current stabilization and
current limiting.

*1,*2 Pinch-off current limiting current are measured by impulse wave at 25ЊC
*3 ZT is minimum AC impedance when small AC signal voltage of 10KHz is added tc 25 VDC bias. ZT is used as the reference value.
*4 Temperature coefficient is measured between 25ЊC and 50ЊC.
