Stable voltage Vz

  The voltage value at both ends of the Vz voltage regulator when its current reaches the specified value after reverse breakdown. The Vz range of different types of voltage regulators varies; The same type of voltage regulator often has a certain degree of dispersion due to differences in manufacturing processes.

  So, Vz is generally given as a range value, for example, the Vz of 2CW11 is between 3.2-4.5V (with a test current of 10mA). Of course, the forward conduction characteristics of diodes (including voltage regulators) also have a stabilizing effect, but the stable voltage is only 0.6~0 8V, and it varies greatly with temperature, so it is generally not commonly used
