SMF4L-T1G Series

Surface Mount - 400 W, Low Leakage Performance

Pb e3

RoHS

Description

The SMF4L-T1G series protects sensitive systems or components

from high voltage, high energy transients. It offers a fast response

time, low Zener impedance, high surge and excellent clamping

capabilities. Because of its small size, it is ideal for use in cellular

phones, portable devices, business machines, power supplies and

other industrial and consumer applications.

Features

Stresses exceeding Maximum Ratings may damage the component. Maximum Ratings are

stress ratings only. Functional operation above the Recommended Operating Conditions is

not implied. Extended exposure to stresses above the Recommended Operating Conditions

may affect component reliability.

Applications

SMF4L-T1G Series is ideal for the protection of I/O interfaces, Vcc

bus and other vulnerable circuit used in cellular phones, portable

electronics, business machines, power supplies and other

consumer applications. The low leakage is particularly well suited

for battery operated electronics.
