CV5109 saturated emission diode

Size
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 voltage1.8V
Max anode voltage500V
Max anode voltage to ensure saturation100V
Filament current at 1.8V330mA
Anode current (Vf=1.8, Va=500)0.65mA
Typical operation
Anode current (saturated)0.3mA
Filament voltage1.65V
Filament current320mA
Min anode voltage100V
Max anode voltage500V
