The TDA6107AJF contains three video output amplifiers which are intended to drive the
three cathodes of a color CRT. The device is contained in a plastic DIL-bent-SIL 9-pin
medium power (DBS9MPF) package, and uses high-voltage DMOS technology.
To obtain maximum performance, the amplifier should be used with black-current control.

8.1 Thermal protection
The internal thermal protection circuit gives a decrease of the slew rate at high
temperatures: 10 % decrease at 130 °C and 30 % decrease at 145 °C (typical values on
the spot of the thermal protection circuit).

The cathode output is protected against peak currents (caused by positive voltage peaks
during high-resistance flash) of 3 A maximum with a charge content of 100 µC. External
protection against higher currents is described in
The cathode is also protected against peak currents (caused by positive voltage peaks
during low-resistance flash) of 6 A maximum with a charge content of 100 nC. External
protection against higher currents is described in
The DC voltage of pin VDD must be within the operating range of 180 V to 210 V during
the peak currents.
10.2 Flashover protection
The TDA6107AJF incorporates protection diodes against CRT flashover discharges that
clamp the cathodes output voltage up to a maximum of VDD+Vd.
To limit the diode current an external 1.5 kΩ 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).
VDD must be decoupled to GND:
1. With a capacitor > 20 nF with good HF behavior (e.g. foil); this capacitor must be
placed as close as possible to pins VDDand GND and must be within 5 mm.
2. With a capacitor > 3.3 µF on the picture tube base print, depending on the CRT size.
10.3 Switch-off behavior
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).
10.4 Bandwidth
The addition of the flash resistor produces a decreased bandwidth and increases the rise
and fall times.

10.5 Dissipation
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 TDA6107AJF must be mounted on the picture tube base print to minimize the load
capacitance.
Inputs and outputs are protected against electrostatic discharge in normal handling.
However, to be completely safe, it is desirable to take normal precautions appropriate to
handling integrated circuits.
14. Soldering
14.1 Introduction to soldering through-hole mount packages
This text gives a brief insight to wave, dip and manual soldering. A more in-depth account
of soldering ICs can be found in our
(document order number 9398 652 90011).
Wave soldering is the preferred method for mounting of through-hole mount IC packages
on a printed-circuit board.
14.2 Soldering by dipping or by solder wave
TDA6107AJF
Triple video output amplifier
Data Handbook IC26; Integrated Circuit Packages
Driven by legislation and environmental forces the worldwide use of lead-free solder
pastes is increasing. Typical dwell time of the leads in the wave ranges from
3 seconds to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb
or Pb-free respectively.
The total contact time of successive solder waves must not exceed 5 seconds.
The device may be mounted up to the seating plane, but the temperature of the plastic
body must not exceed the specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling may be necessary immediately
after soldering to keep the temperature within the permissible limit.
14.3 Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the package, either below the
seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is
less than 300 °C it may remain in contact for up to 10 seconds. If the bit temperature is
between 300 °C and 400 °C, contact may be up to 5 seconds.
