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.
ESD protection with ESDAxxSCx
Electrostatic discharge (ESD) is a major cause of failure in
electronic systems. Transient Voltage Suppressors (TVS) are an
ideal choice for ESD protection. They are capable of clamping the
incoming transient overvoltage 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 and 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.
