Zener diode SG301SK, USSR, 1984
Corona discharge zener diode is an ion gas discharge electric vacuum device designed to stabilize the voltage (400 V ... 30 kV) at low current consumption (several tens of microamps ) (to power a CRT , PMT , Geiger counters ). Filled with hydrogen under atmospheric pressure.
The corona discharge zener diode has a cylindrical coaxial shape. The outer cylindrical electrode is the cathode , and the inner is the anode . The stabilization voltage depends on the gas pressure.
