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.
θ
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.

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 =
θ
LA PD + TA
where
θ
LA is lead-to-ambient thermal resistance
and
PD is power dissipation.
θ
LA is generally 30–40°C/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 +
θ
JL PD
where
θ
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
θ
JL.
