30AE3

30AE3 is also designated PY88.

Construction

The Rogers 30AE3 is a booster diode for use in line-timebase circuits of transformerless television receivers. It has a coated, unipotential cathode, an E9-1 base with 9CB basing, a T6 1/2 bulb, and a C1-2 top cap. The tube can be mounted in any position.

Ratings

The heater is rated at 30 volts and 300 mA. Capacitance from plate to all other elements is 8.6 pF, and from cathode to heater is 2.0 pF. Maximum ratings include a supply voltage without current of 550 volts, a supply voltage of 250 volts, a plate current of 220 mA, a peak plate current of 550 mA, a plate dissipation of 5 watts, a peak negative plate voltage of 6000 volts, a peak voltage between heater and cathode of 6600 volts, and a voltage between heater and earth of 220 volts r.m.s. The maximum pulse duration for the peak voltage ratings is 22% of a cycle with a maximum of 18 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.
