Vacuum Tube - 6626 / 0A2WA, Diode, Gas
New-Old-Stock (NOS) tube.
The 0A2WA is a cold cathode, gas-filled diode of miniature construction designed for reliable service as a voltage regulator. It has an operating current range of 5 to 30 milliamperes over which it maintains a substantially constant operating voltage of 150 volts. Three cathode pins are provided which may be used to disconnect the load when the tube is removed from the socket. This type is characterized by long life and it is designed for service where severe conditions of high temperature and mechanical shock or vibration are encountered.
