TECHNICAL DATA

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.

APPLICATION NOTE

200

150

As the current available from the diode is temperature dependent,

it is necessary to determine junction temperature, T , under specific

operating conditions to calculate the value of the diode current. The

following procedure is recommended:

POINT OF LEAD TEMPERATURE

MEASUREMENT

Lead Temperature, T , shall be determined from:

= θ

P + T

LA D A

where

and

is lead-to-ambient thermal resistance

is power dissipation.

(MOST HEAT CONDUCTION IS

THROUGH THE CATHODE LEAD)

is generally 30–40°C/W for the various clips and tie points

in common use, and for printed circuit-board wiring.

Junction Temperature, T , shall be calculated from:

= T + θ

Figure 2. Typical Thermal Resistance

For circuit design limits of V , limits of P may be estimated and

extremes of T may be computed. Using the information on Figures

4 and 5, changes in current may be found. To improve current

regulation, keep V

especially the cathode lead, to reduce θ

low to reduce P and keep the leads short,
