UL,cUL approved
Complete lead-free

The signal transmission rate of personal computer peripheral devices and digital devices as represented by USB2.0 devices is being increased year by year, and countermeasures against ESD are critical in high-frequency bands. We have developed Type KVA Surge Absorber to protect the circuits of various electronic devices sensitive to ESD.
Since the surge absorber has a low capacitance of 0.08 pF, it is applicable to high-speed signal lines.
The ecology design of Type KVA is environmentally friendly because of Lead-free and Halogen-free.


Type KVA
Category Temperature Range -40~+125℃
Rated Voltage 24VDC
Trigger Voltage 1000V max. (650V typ.)
Clamp voltage 200V max. (100V typ.)
Capacitance 1608size:0.2pF max. (0.08pF typ.)


  • Usable on high-speed signal lines
  • Large ESD endurance and high insulation resistance
  • No polarity. Protection of circuit against ESD from both directions
  • Suitable for automatic mounting by chip placer
  • Precise dimensions allows high-density mounting and symmetrical construction of terminal provide “Self-Alignment”.
  • Resistance to soldering heat : Reflow or flow soldering 10 seconds at 260℃
  • High accuracy carrier tape by using pressed pocket ensures excellent mounting.
  • Lead-free and RoHS Compliant
