VSMF05LC
MuLti-Line Low CaPaCitanCe tVS aRRay
DeSCRiPtion
The VSMF05LC is a 5 Volt, low capacitance, multi-line TVS array. This device is designed to protect wireless tele-
communications and portable electronic applications from the damaging effects of ESD and EFT. The VSMF05LC is
available in a 4 line unidirectional configuration with a working voltage of 5 Volts and a minimum breakdown voltage
of 6 Volts. This device is rated at 25 Watts peak pulse power, which is sufficient protection for tertiary type lightning
threats at key interface locations.
Packaged in a miniature SOT-953, the VSMF05LC meets IEC 61000-4-2 (ESD) and 61000-4-4 (EFT) immunity require-
ments. Each device should be placed near a connector to provide the best protection against transients.
