WebJun 27, 2024 · Current I z (maximum) – It is the maximum current reading at the rated Zener Voltage, which is V z – 200μA to 200 A Voltage Tolerance – It’s typically ±5% Current I z (minimum) – It is the minimum value of the current reading required for the diode to break down. Temperature Stability – it has the best stability of around 5 V. WebSince diodes with high breakdown voltage are lightly doped, they form a wide depletion layer (forbidden band). Conversely, since diodes with low breakdown voltage are heavily doped, they form a thin depletion layer (forbidden band). When a diode has a wide depletion layer, electron tunneling (Zener breakdown) is less likely to occur, causing ...
