Extras ▼

 

The EZ90 miniature HT rectifier follows the normal pattern for a full wave device in that a common cathode is employed.
The data-sheet gives the intended use as compact power supplies such as would be found in car radios.
The central cathode with the anodes stacked around it.
The lower anode is seen face on and the top anode is seen edge on.
The thin glass tube envelope is 18 mm in diameter and the length, excluding the B7G base pins, is 58 mm.
