NOTE:
3. When used as a zener for reference voltage, the device must not be subjected to more than 0.1mJ of energy from any possible capacitance or
electrostatic discharge in order to prevent degradation of the junction. Maximum operating zener current should be less than 10mA.

4. This circuit was chosen because it conveniently
represents a close approximation in performance to a
properly unilateralized single transistor of this type. The
use of Q3 in a current-mirror configuration facilitates
simplified biasing. The use of the cascode circuit in no
way implies that the transistors cannot be used
individually.
5. E.F. Johnson number 160-104-1 or equivalent.
