PIN FUNCTIONS
Pin 1: Heater Positive. Must have a higher positive value
than Pin 2 and Pin 4.
Pin 2: Heater Negative. Must have a higher positive value
than Pin 4. Must have equal or lower potential than Pin 1.
Pin 3: Zener Positive. Must have a higher positive value
than Pin 4.
Pin 4: Substrate and Zener Negative. Must have a higher
positive value than Pin 7. If Q1 is zenered (about 7V) a
permanent degradation in beta will result.
Pin 5: Temperature Compensating Transistor Collector.
Pin 6: Temperature Sensing Transistor Base. If the base
emitter junction is zenered (about 7V) the transistor will
suffer permanent beta degradation.
Pin 7: Emitter of Sensing and Compensating Transistors.
Pin 8: Collector of Sensing Transistor.
