FEATURES
ESDA6V1BC6With the focusof lowering the operation levels, the problemof malfunction causedby the environmentis
critical. Electrostatic discharge (ESD)isa major causeof failurein electronic system.
Transient Voltage Suppressors are an ideal choice for ESD protection and have proven capablein
suppressing ESD events. They are capableof clamping the incoming transienttoa low enough level such
that damageto the protected semiconductoris prevented.
Surface mount TVS arrays offer the best choice for minimal lead inductance.
They serveas parallel protection elements, connected between the signal lineto ground.As the transient
rises above the operating voltageof the device, the TVS array becomesa low impedance path diverting the
transient currentto ground.
ESD protectionby ESDA6V1BC6
Bidirectional protection for 0V biased signals.The ESDA6V1BC6 arrayis the ideal product for use as board level protectionof ESD sensitive
semiconductor components.
The tiny SOT23-6L package allows design flexibilityin the designof “crowded” boards where the space
savingisata premium. This enablesto shorten the routing and can contributeto improve ESD
performance.
Circuit Board LayoutCircuit board layoutisa critical design stepin the suppressionof ESD induced transients. The following
guidelines are recommended: The ESDA6V1BC6 shouldbe placedas nearas possibleto the input terminalsor connectors. Minimise the path length between the ESD suppressor and the protected device Minimiseall conductive loops, including power and ground loops The ESD transient return pathto ground shouldbe keptas shortas possible. Use ground planes whenever possible.
