FLASHOVER PROTECTION
The TDA6120Q does NOT include protection diodes that
clamp the cathode output pin to the high voltage supply pin
during a CRT flashover discharge. Therefore an external
high voltage reverse biased diode has to be connected
between the OUTC pin and the VDD pin. An external 147 Ω
carbon high-voltage resistor in combination with a 2 kV
spark gap between the cathode and ground will limit the
maximum clamp current (for this resistor value, the CRT
has to be connected to the main printed-circuit board).
This external network causes an increase in the rise and
fall times and a decrease in the overshoot.
Pin 10 must be decoupled to pin 8:
•By a capacitor >22 nF with good HF behaviour (e.g. foil).
This capacitor must be placed as close as possible to
pin 10 and pin 8; definitely within 5 mm.
•By a capacitor >3.3 µF on the picture tube base printed
circuit board (common for three output stages).

TEST AND APPLICATION INFORMATION
Dissipation
Regarding dissipation, distinction must be made between
static dissipation (independent of frequency) and dynamic
dissipation (proportional to frequency). The static
dissipation of the TDA6120Q is due to supply currents, and
currents in the feedback network and CRT.
The static dissipation is given by the following equation:
Where:
Rf= feedback resistance
IOUTC = DC cathode current.
The dynamic dissipation is given by the following equation:

Where:
CL= load capacitance
Cint = effective internal load capacitance
(approximately 7 pF)
f = frequency
VOUTC(p-p) = output voltage (peak-to-peak value)
b = non-blanking duty cycle (0.8).
The IC must be mounted on the picture tube base
printed-circuit board to minimize the load capacitance CL.
Switch-off
The voltage at output pins OUT and OUTC will be pulled
to ground when the low voltage supply voltage (VCC) is
switched off.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
“IC Package Databook”
(order code 9398 652 90011).
Soldering by dipping or by wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. 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 (Tstg max). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, 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 and 400 °C, contact may be up to 5 seconds.

Information as of 2000-08-22
TDA6120Q; Video output amplifier
The TDA6120Q is a single 30 MHz, 125 V (p-p) video output amplifier contained in a plastic DIL-bent-SIL power package. The device uses
high-voltage DMOS technology and is intended to drive the cathodes of a CRT in High Definition TVs (HDTVs) or monitors.
lHigh large signal bandwidth of 32 MHz (typ.) at 125 V (p-p)
lHigh small signal bandwidth of 47 MHz (typ.) at 60 V (p-p)
lRise/fall time of 12.5 ns for 125 V (p-p)
lHigh slew rate of 10 V/ns
lLow static power dissipation of 2.5 W at 200 V supply voltage
lHigh maximum output voltage
lBandwidth independent of voltage gain
lMaximum overall voltage gain over 46 dB
lHigh Power Supply Rejection Ratio (PSRR)
lFast cathode current measurement output for dark current control loop
lDifferential voltage input.
