The 6DW4 is an efficiency diode for American 525 line television receivers. Full operating details are to be found in the data sheet, but in essence the operation is at high voltage and high peak current in a pulse environment (TV line output system) and the diode clamps the circuit and returns excess energy back into the HT reservoir capacitor.

The anode is formed from a pair of shaped flat plates stitched together. The size is required to dissipate 8.5 Watts.

The wide glass tube envelope is 29 mm in diameter, and excluding the B9D base pins is 77 mm tall.
