6X2

6X2 is also designated EY51.

Description

The 6X2 is a heater-coated unipotential tube with no base, as described in the Philips datasheet. It is a diode intended for use in high-voltage rectifier applications, with a maximum overall length of 2.087 inches and a maximum diameter of 0.571 inches. The tube can be mounted in any position.

Ratings

The 6X2 operates with a heater voltage of 6.3 volts and a heater current of 90 mA. The capacitance between plate and cathode is 0.8 µµF.

For operation at 60 c/s with sinusoidal input voltage, the maximum peak inverse plate voltage is 14,000 volts, the maximum DC output current is 3 mA, the maximum filter input capacitor is 0.1 µF, and the minimum total effective plate supply impedance is 0.1 megohm. For operation at 10,000 to 500,000 c/s with sinusoidal voltage, the maximum peak inverse plate voltage is 17,000 volts, the maximum DC output current is 3 mA, the maximum filter input capacitor is 0.01 µF, and the minimum total effective plate supply impedance is 0.1 megohm.

For use as a pulse type E.H.T. supply, the maximum peak inverse voltage is 17,000 volts, the maximum DC output current is 0.2 mA, the maximum peak plate current is 80 mA, and the maximum filter input capacitor is 5000 µµF. In this pulse mode, the maximum pulse duration is ½% of one cycle, with a maximum of 5 microseconds.

Equivalence is asserted only where the archive's own literature states it directly, in at least 40 separate documents. Tubes that merely substitute in some circuits are not listed here.
