Half-Wave Rectifier
The 3DJ6 Vacuum tube is a heater - cathode type diode
designed for use in color television receivers as the
high - voltage rectifier to supply power to the anode of
the picture tube. Features of the tube include a
diffusion bonded cathode coating to minimize reverse
emission failures and X- radiation controls.
The Diffusion bonded cathode coating practically
eliminates one of the major failure mechanisms in
high - voltage rectifiers, which is back emission from
the anode due to emissive particles being pulled from
the cathode by the very high electrostatic field.
The 3DJ3 features built - in X - radiation shielding and
additional design and specification controls for the
reduction of X - radiation output.
