The DD41 from Mazda was introduced in 1938. This double diode was designed for signal rectification and features an internal screen as well as external metalisation.
The HL41DD was used in the 1948 Murphy television receiver V114 as a noise suppressor and pulse separator.
The classic envelope is 32 mm in diameter and, excluding the MO base pins, is 68 mm tall.
