IEC61000-4-2 15kV (air discharge)kV (contact discharge)
COMPLIES WITH THE FOLLOWINGSTANDARDS: T-filtering functionsfor2 wires. ESD protectionof15kV (air discharge) per
IEC61000-4-2 Breakdown voltage: VBR=6V min. Low leakage current<1 μA.
FEATURES
FUNCTIONAL DIAGRAM EMI/ RFI noise suppression. Enhanced ESD protection: IEC1000-4-2 level4 Oneof the smallest protection circuits available High flexibilityin the designof high density
boards
BENEFITSEMI FILTER
WITH ESD PROTECTION
Application Specific Discretes
A.S.D.TM
Where EMI filteringin ESD sensitive equipmentis
required: Mobile phone: handsets and accessories RF communications
MAIN APPLICATIONSThe EMIF01-5250SC5 isa highly integrated
T-filter designedto suppress EMI/ RFI noise on
I/O portsof mobile phonesor RF communication
equipment.
This filter includes ESD protection circuitry which
prevents device destruction when subjectedto
ESD discharges.
The comprehensive layout of the
EMIF01-5250SC5 filter allows design flexibilityon
high density boards.

Figures3 and4 show the EMIF01-5250SC5
responseto air and contact discharge conditions
respectively at input and output pins. These
figures indicate that the responseis spontaneous
and the output levelis keptat safe operating
voltages.
