HIGH SPEED TYPE CHIP VARISTORS

•

Typical ESD failure voltage for CMOS and/or Bi Polar is

≥200V.

• 15kV ESD pulse (air discharge) per IEC 1000-4-2.Level 4, generates <2OmJ of energy.

• Low capacitance (<200pF) is required for high-speed data transmission.

• Low leakage current(lL) is necessary for battery operated equipment.

TERMINOLOGY

• VWM: Maximum steady state DC operating voltage the varistor can maintain and not exceed

50

µA leakage current.

• VB: Voltage across the device measured at 1 mA DC current

• VC: Maximum peak voltage across the varistor measured at a specified pulse and

waveform

•

Ipeak: Maximum peak current which may be applied with the specified waveform without

device failure

•

C: Device capacitance measured @0.5Vrms and 1MHz with zero volt bias applied.
