7. Overvoltage test circuit (DSSV-YD)


When the applied overvoltage is between tip and ring, the communication line is cut off by the wire opening.



8. CRT(cathode ray tube)

(DSA and DSP series protect display driver IC and transistors from damage due to ingress of static surge.)

9. CRT(cathode ray tube)

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. 		 

10. 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.
