Dual Transient Voltage Suppressors Array for ESD Protection
General Description
The LGSOT12CLT1G is a dual monolithic 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. It can also
work as bidirectional suppressor by connecting only
pin1 and 2.

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 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.
The LGSOT12CLT1G array 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.
