CV5109 saturated emission diode
|
This valve measures 72x31mm overall and has an octal base |
This is a directly heated tungsten filament diode intended for operation with temperature
limited emission. The large change in anode current resulting from a small change in filament voltage
together with the stability of the valve make it suitable for use as a control in stabiliser circuits.
| Max filament voltage | 1.8V |
| Max anode voltage | 500V |
| Max anode voltage to ensure saturation | 100V |
| Filament current at 1.8V | 330mA |
| Anode current (Vf=1.8, Va=500) | 0.65mA |
