Abstract
Electronic circuits in certain space missions are exposed to very low temperatures. Very limited data
exist on the performance and reliability of electronic devices and circuits at cryogenic temperatures
below the manufacturer’s specified operating temperature range. This database can be used as a
design tool for screening and identifying diodes with potential use in extreme temperature
applications. Therefore, the present paper summarizes the preliminary results obtained on the
evaluation of shunt voltage regulators based on different breakdowns of Zener diodes whenever they
operate at very low temperature levels. The performance of Zener voltage regulator was evaluated
under a wide temperature range from 300 to 93 K. In this concern, six sets of Zener diodes of the
types BZV86-1V4, BZX83-C3V6, BZX79-C4V7, BZX79-C5V6, BZX83-C6V8 and BZX55C9V1
covering a wide range of low breakdown voltages (from 1.40 to 9.10 V), were chosen. The devices
were evaluated in terms of their output voltages at different input voltage levels (line regulation), and
at constant load current as a function of temperature. The effect of temperature on load regulation was
also established for different load levels up to 21.0 mA, at constant input voltage, over the low
temperature range of 300 to 93 K.
