Applications

Mechanical Characteristics

The SMS series of TVS arrays are designed to protect

sensitive electronics from damage or latch-up due to

ESD and other voltage-induced transient events. Each

device will protect up to four lines. They are available

with operating voltages of 5V, 12V, 15V and 24V. They

are unidirectional devices and may be used on lines

where the signal polarities are above ground.

TVS diodes are solid-state devices designed specifically

for transient suppression. They feature large cross-

sectional area junctions for conducting high transient

currents. They offer desirable characteristics for board

level protection including fast response time, low

operating and clamping voltage and no device degrada-

tion.

The SMS series devices may be used to meet the

immunity requirements of IEC 61000-4-2, level 4. The

low cost SOT23-6L package makes them ideal for use

in portable electronics such as cell phones, PDA’s, and

notebook computers.
