TECHNICAL DATA
Current Regulator Diodes
Field-effect current regulator diodes are circuit elements that provide a current essentially independent of voltage. These diodes are especially designed for maximum impedance over the operating range. These devices may be used in parallel to obtain higher currents.

SYMBOLS AND DEFINITIONS
ID -- Diode Current. IL -- Limiting Current: 80% of IP minimum used to determine Limiting voltage, VL. IP -- Pinch-off Current: Regulator current at specified Test Voltage, VT. POV -- Peak Operating Voltage: Maximum voltage to be applied to device. l -- Current Temperature Coefficient. VAK -- Anode-to-cathode Voltage. VK -- Knee Impedance Test Voltage: Specified voltage used to establish Knee Impedance, ZK. VL -- Limiting Voltage: Measured at IL, VL, together with Knee AC Impedance, ZK, indicates the Knee characteristics of the device. VT -- Test Voltage: Voltage at which IP and ZT are specified. ZK -- Knee AC Impedance at Test Voltage: To test for ZK, a 90 Hz signal VK with RMS value equal to 10% of test voltage, VK, is superimposed on VK: ZK = VK/iK where iK is the resultant ac current due to VK. To provide the most constant current from the diode, ZK should be as high as possible; therefore, a minimum value of ZK is specified. ZT -- AC Impedance at Test Voltage: Specified as a minimum value. To test for ZT, a 90 Hz signal with RMS value equal to 10% of Test Voltage VT, is superimposed on VT.

APPLICATION NOTE
200 POINT OF LEAD TEMPERATURE MEASUREMENT As the current available from the diode is temperature dependent, it is necessary to determine junction temperature, TJ, under specific operating conditions to calculate the value of the diode current. The following procedure is recommended: Lead Temperature, TL, shall be determined from: TL = LA PD + TA where LA is lead-to-ambient thermal resistance and PD is power dissipation. LA is generally 30-40C/W for the various clips and tie points in common use, and for printed circuit-board wiring. Junction Temperature, TJ, shall be calculated from: TJ = TL + JL PD where JL is taken from Figure 2. For circuit design limits of VAK, limits of PD may be estimated and extremes of TJ may be computed. Using the information on Figures 4 and 5, changes in current may be found. To improve current regulation, keep VAK low to reduce PD and keep the leads short, especially the cathode lead, to reduce JL.
