ESDA6V1-4BC6
1. ESD protection by ESDA6V1-4BC6
With the focus of lowering the operation levels, the problem of malfunction caused by the environment is
critical. Electrostatic discharge (ESD) is a major cause of failure in electronic system.
Transient Voltage Suppressors are an ideal choice for ESD protection and have proven capable in
suppressing ESD events. They are capable of clamping the incoming transient to a low enough level such
that damage to the protected semiconductor is prevented.
Surface mount TVS arrays offer the best choice for minimal lead inductance.
They serve as parallel protection elements, connected between the signal line to ground. As the transient
rises above the operating voltage of the device, the TVS array becomes a low impedance path diverting the
transient current to ground.
Bidirectional protection for 0V biased signals.

The ESDA6V1-4BC6 array is the ideal product for use as board level protection of ESD sensitive
semiconductor components.
The tiny SOT23-6L package allows design flexibility in the design of “crowded” boards where the space
saving is at a premium. This enables to shorten the routing and can contribute to improve ESD
performance.
2. Circuit Board Layout
Circuit board layout is a critical design step in the suppression of ESD induced transients. The following
guidelines are recommended :
s The ESDA6V1-4BC6 should be placed as near as possible to the input terminals or connectors.
s Minimise the path length between the ESD suppressor and the protected device
s Minimise all conductive loops, including power and ground loops
s The ESD transient return path to ground should be kept as short as possible.
s Use ground planes whenever possible.
