The SFC05-4 is a quad flip chip CSP TVS diode array.
They are state-of-the-art devices that utilize solid-state
silicon-avalanche technology for superior clamping
performance and DC electrical characteristics. The
SFC series TVS diodes are designed to protect sensi-
tive semiconductor components from damage or latch-
up due to electrostatic discharge (ESD) and other
voltage induced transient events.
The SFC05-4 is a 6-bump, 0.5mm pitch flip chip array
with a 3x2 bump grid. It measures 1.5 x 1.0 x
0.65mm. This small outline makes the SFC05-4
especially well suited for portable applications. CSP
TVS devices are compatible with current pick and place
equipment and assembly methods.
Each device will protect up to four data or I/O lines.
The CSP design results in lower inductance, virtually
eliminating voltage overshoot due to leads and inter-
connecting bond wires. They may be used to meet the
ESD immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
