źródło ,,bocznikowe" (shunt) działa podobnie do diody Zenera?

z wiki:

A subsurface Zener diode, also called 'buried Zener', is a device
similar to the surface Zener, but with the avalanche region located
deeper in the structure, typically several micrometers below the oxide.
The hot carriers then lose energy by collisions with the semiconductor
lattice before reaching the oxide layer and cannot be trapped there. The
Zener walkout phenomenon therefore does not occur here, and the buried
Zeners have voltage constant over their entire lifetime. Most buried
Zeners have breakdown voltage of 5-7 volts. Several different junction
structures are used.[7]
