DESCRIPTION
The SSESD03C is designed to protect voltage sensitive components from ESD and transient voltage events. Excellent
clamping capability, low leakage, and fast response time, make these parts ideal for ESD protection on designs where
board space is at a premium. Because of its small size, it is suited for use in cellular phones, MP3 players, digital cameras
and many other portable applications where board space is at a premium.

RATINGS AND CHARACTERISTICS CURVES
APPLICATION NOTE
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 to a low enough level such
that damage to the protected semiconductor is prevented.
Surface mount TVS offers the best choice for minimal lead inductance. They serve as parallel protection elements,
connected between the signal lines to ground. As the transient rises above the operating voltage of the device, the TVS
becomes a low impedance path diverting the transient current to ground. The SSESD0
3C is the ideal board-level
protection of ESD sensitive semiconductor components.
The tiny SOD-923 package allows design flexibility in the design of high density boards where the space saving is
at a premium. This enables to shorten the routing and contributes to hardening against ESD.
