(8/20 µs waveform)
■ ESD protection level better than
IEC 61000-4-2, level 4:
30 kV contact discharge
■ Low leakage current (< 0.5 µA @ 5 V)
Benefits
■ High EOS and ESD protection level
■ High integration
■ Suitable for high density boards
Complies with the following standards:
■ IEC 61000-4-2 level 4
– ±15 kV (air discharge)
– ±8 kV (contact discharge)
■ MIL STD 883G - Method 3015-7: class 3B
– HBM (human body model): ≥8kV
Applications
This product is particularly recommended for the
protection of power supply lines of portable
devices, where EOS and ESD transient
overvoltage protection in sensitive equipment is
required, such as:
■ Computers
■ Printers
■ Communication systems
■ Cellular phone handsets and accessories
■ Video equipment
