(DSA and DSP series protect display driver IC and transistors from damage due to ingress of static surge.)
Screen size 15" under 15" up
Between cathode and GND
Heater
Between grids and GND
Note : For this application, please check for hold over.
Car radio, radio cassette, wireless
Inserted in the antenna input terminal, the surge absorber will protect the semiconductor (frontend IC or FET, etc.)against failure due to static surge entering from the antenna.
RF amplifier
Frequency modulation
Detector
LF amplifier
Boosters (for satellite broadcasting and general TV equipment)
In this application, the surge absorber protects the semiconductor against small surge energies from the vicinity of the antenna or against static electricity due to human contact. The recent use of high-sensitivity FET has led to a stronger requirement for surge protection.
