Diode

The Tung-Sol CH1027 is a subminiature, nitrogen-filled constant-current discharge device marketed as a Curpistor. It uses radioactive ionization to establish highly stable, extremely small currents over a broad voltage range. Different family suffixes provide nominal currents from nanoampere to picoampere levels.
