The EY51 is a high voltage rectifier for use in television and similar EHT circuits.

The valve is designed for pulsed operation. The anode PIV is 17 kV and the rectified current has a maximum average value of 350 µA and a peak value of 80 mA. The reservoir capacitor can take a maximum value of 5,000 pF.

The thin glass tube envelope is 13 mm in diameter and, excluding the base wires is 48 mm tall.
