The best trade-off
To meet market requirements and to provide optimized cost and market segment differentiation
STMicroelectronics has enhanced its damper diode range and has released a new damper
range for CRT TV and new 3-pin full molded TO-220 package for CRT Monitor.
4.1
CRT TV application
For CRT TV application the maximum deflection frequency is 56kHz (HDTV). Both
DTV1500SDFP and DTV1500HDFP are optimized and fit CRT TV horizontal deflection designs
assuming the design rules are fulfilled.
For example, when the design rules are more severe (as regards to the case temperature (T
c
))
or when the deflection frequency increases (V
FP
becomes more critical) the choice can turn to
the DTV1500HDFP.
