The LC04-12 has been specifically designed to protect
sensitive components which are connected to high-
speed telecommunications lines from over voltages
caused by lightning, ESD (electrostatic discharge), and
EFT (electrical fast transients).
The device is in a JEDEC SO-16 NB package. It is
designed to provide metallic (Tip to Ring) or common
mode (Tip to Ground & Ring to Ground) surge protec-
tion for up to two Tip and Ring pairs. The low capaci-
tance topology means signal integrity is preserved on
high-speed lines. The high surge capability (600W,
tp=10/1000µs) makes the LC04-12 suitable for
telecommunications systems operating in harsh tran-
sient environments. The LC04-12 is designed to meet
the lightning surge requirements of Bellcore GR-
1089(intra-building), ITU K.20, and IEC 61000-4-5.
The features of the LC04-12 are ideal for protecting
ADSL, RS-232, RS-423, RS-422, and V.90 interfaces.
