Silicon surge protection element (silicon varistor)
Absorb overvoltage (surge) generated in the signal line of telephone sets, digital communication lines and ISDN terminal equipment
Symbol
Features
- 1 Low junction capacitance: Since the junction capacitance is small, it can be connected directly to the signal line.
- 2 It can bidirectional surge absorption and has clamping voltage of 2.75V/6.875V lineup.
Point of selection
- 1 VF2:2.75V products for protecting the line of 2.5V or less… VRYA6, VR-61F1
- 2 VF2: 6.875V products for protecting the line of 5V or less… VRYA15
