10.3 Switch-off behavior
10.4 Bandwidth
10.5 Dissipation
To limit the diode current an external 1.5 k carbon high-voltage resistor in series with the
cathode output and a 2 kV spark gap are needed (for this resistor value, the CRT has to
be connected to the main PCB).
V
The switch-off behavior of the TDA6107AJF is controllable. This is because the output
pins of the TDA6107AJF are still under control of the input pins for low power supply
voltages (approximately 30 V and higher).
The addition of the flash resistor produces a decreased bandwidth and increases the rise
and fall times.
A distinction must first be made between static dissipation (independent of frequency) and
dynamic dissipation (proportional to frequency).
The static dissipation of the TDA6107AJF is due to voltage supply currents and load
currents in the feedback network and CRT.

The dynamic dissipation P
Where:
The TDA6107AJF must be mounted on the picture tube base print to minimize the load
capacitance.
1. With a capacitor > 20 nF with good HF behavior (e.g. foil); this capacitor must be
2. With a capacitor > 3.3 F on the picture tube base print, depending on the CRT size.
