Constant-current diode - Wikipedia
Constant-current diode is an electronic device that limits current to a maximal specified value for the device. It is known as current-limiting diode (CLD), current-regulating diode (CRD). These diodes consist of an n-channel JFET with the gate shorted to the source, which functions like a two-terminal current limiter or current source (analogous to a voltage-limiting Zener diode).

Breakdown Voltage - an overview | ScienceDirect Topics
The normal reverse characteristic of any silicon diode is to withstand reverse voltages until a threshold value at which reverse current increases rapidly. The Zener type of diode is constructed so that the breakdown of resistance for reverse voltage is particularly rapid, leading to a characteristic for the type illustrated in Figure 3.8 , with a very steep slope at the breakdown voltage .
