Diode Current IL Limiting Current of IP minimum used to determine Limiting Voltage, V L Current Temperature Coefficient. V AK anode to cathode Voltage Pinch-off Current: Regulator current at specified Test Voltage, IP is some times identified as IS Peak Operating Voltage: Maximum voltage to be applied to the device. Knee Impedance test voltage: Specified voltage used to establish Knee Impedance Limiting Voltage: Measured at IL, V L, together with Knee ac Impedance, ZK , indicates the Knee characteristic of the device TEST VOLTAGE: Voltage at which IP and ZS are specified Knee ac impedance at Test Voltage: To test a 90Hz signal V K with rms value equal 10% of test voltage K is superimposed V K /iK where iK is the resultant ac current due K. To provide the most constant current from the diode, ZK should be as high as possible, therefore, a minimum value ZK is specified. AC Impedance at Test Voltage: Specified as a minimum value. To test for 90 Hz signal V S with rms value equal 10% of test voltage, S is superimposed v S /iS where iS is the current due v S.
