Notes
1. If the difference between V
2. SVRR: The ratio of the change in supply voltage to the change in input voltage when there is no change in output
Cathode output
The cathode output is protected against peak currents
(caused by positive voltage peaks during high-resistance
flash) of 5 A maximum with a charge content of 100 C.
The cathode is also protected against peak currents
(caused by positive voltage peaks during low-resistance
flash) of 10 A maximum with a charge content of 100 nC.
Flashover protection
The TDA6101Q incorporates protection diodes against
CRT flashover discharges that clamp the cathode output
pin to the V
has to be within the operating range of 180 to 210 V to
ensure that the Absolute Maximum Rating for V
250 V will not be exceeded during flashover. To limit the
diode current, an external 820
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). This addition produces an
increase in the rise and fall times of approximately 5 ns
and a decrease in the overshoot of approximately 3%.

Switch-off behaviour
The switch-off behaviour of the TDA6101Q is defined:
when the bias current becomes zero, at V
than approximately 5 V, all the output pins
(pins 7, 8 and 9) will be high.
