Transient Voltage Suppressors for ESD Protection
General Description
LGS0T12LT1G
The LGS0T12LT1G is a transient voltage suppressor
designed to protect components which are connected
to data and transmission lines against ESD. It clamps
the voltage just above the logic level supply for
positive transients, and to a diode drop below ground
for negative transients.

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 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 becomes a low impedance path diverting the transient current to ground. The LGS0T12LT1G is
the ideal board evel protection of ESD sensitive semiconductor components.
The tiny SOT23 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 againt ESD.
