Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Single-way rectifier | 1200V | - | 150 | - | 220mA |
| Two-way rectifier (dual tubes) | 850V | - | 150 | - | 400mA |
| Static Characteristic | 30V | - | - | - | 200mA |
Application Notes
Anode voltage should be switched on only after cathode warmup. If not possible, the maximum inverse voltage must be reduced to 2000V. Serial heater connection of two tubes is allowed only in two-way rectifier configuration.
