What is the stability coefficient of a voltage regulator diode?
The stable voltage temperature coefficient of the voltage regulator diode: Changes in temperature will cause VZ to change. In the voltage regulatordiode, when | VZ |>7 V, VZ has a positive temperature coefficient, while reverse breakdown is avalanche breakdown.
When | VZ |<4V, VZ has a Negative temperature coefficient, and reverse breakdown is Zener breakdown.
When 4V<| VZ |<7V, the voltage regulator diode can achieve a temperature coefficient close to zero. This type of voltage regulator diode can be used as a standard voltage regulator.
