Complies with the following standards:
■ IEC 61000-4-2 level 4:
– 15 kV (air discharge)
– 8 kV (contact discharge)
■ MIL STD 883E- Method 3015-7: class3B
– human body model
Applications
Where transient overvoltage protection in ESD
sensitive equipment is required, such as :
■ Computers
■ Printers
■ Communication systems
■ Cellular phone handsets and accessories
■ Other telephone set
■ Set top boxes
Description
The ESDAxxSC5 and ESDAxxSC6 are monolithic
voltage suppressors designed to protect
components which are connected to data and
transmission lines against ESD.
They clamp the voltage just above the logic level
supply for positive transients, and to a diode drop
below ground for negative transient.
