150B2

150B2 is also designated 6354.

General

The 150B2 is a cold cathode voltage stabiliser tube. It has a miniature 7-pin base (also given as E7-1) and a T5½ bulb with outline 5-2. The Philips datasheet identifies the 150B2 as a voltage stabiliser tube; the Rogers datasheet identifies it as a cold cathode tube. The tube should be operated only with the cathode negative and the anode positive.

Ratings and Characteristics

At an anode current of 10 mA, the average operating anode voltage is 150 V, with a minimum of 146 V and a maximum of 154 V. The maximum ignition voltage is 180 V at an illumination of 50–500 lux, and 225 V in complete darkness. The regulation, or voltage variation for an anode current change from 5 to 15 mA, is maximum 5 V. The variation of anode voltage during 1000 hours at an anode current of 10 mA is maximum 1%. The temperature coefficient of the anode voltage is 10 mV/°C. The minimum supply voltage necessary to ensure starting throughout tube life is 180 V.

Limits and Operating Conditions

The maximum anode current is 15 mA, the minimum anode current is 5 mA, and the maximum starting current is 40 mA. The maximum ambient temperature is 90 °C and the minimum ambient temperature is -55 °C. The mounting position is any. Equilibrium conditions are reached within 3 minutes. The tube should not be subjected to severe shock or continuous vibration.

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.
