The VR150 is a gas filled discharge tube that exhibits a near constant voltage across the valve for currents within the range 5mA to 40mA. In fact the regulation is 150 plus or minus 5.5 Volts.

The construction is of a central cold cathode within a cylindrical anode.

The classic envelope is 38 mm in diameter and, excluding the IO base pins, is 88 mm tall.
