The Y-820 is a planar triode intended for use as high voltage series regulator or switch tube. The compact, low inductance package allows fast rise and fall times and very short pulse operation. The plate is conduction-cooled and rated at 400 Watts when used with the proper heatsink. When immersed in oil the maximum plate voltage rating is 25 kilovolts. Solder tabs are supplied to facilitate connection to the heater, cathode and grid terminals. Characteristics Plate Dissipation (Max.) Screen Dissipation (Max.) Grid Dissipation (Max.)
