The SFC3.3-4 is a quad flip chip TVS diode array. They
are state-of-the-art devices that utilize solid-state EPD
TVS technology for superior clamping performance and
DC electrical characteristics. The SFC series TVS
diodes are designed to protect sensitive semiconduc-
tor components from damage or latch-up due to
electrostatic discharge (ESD) and other voltage in-
duced transient events.
The SFC3.3-4 is a 6-bump, 0.5mm pitch flip chip array
with a 3x2 bump grid. It measures approximately 1.5
by 1.0 mm. It has a very low profile of < 0.65 mm.
This is a crucial specification for many portable applica-
tions. 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
interconnecting bond wires.
The devices are constructed using Semtech’s propri-
etary EPD process technology. The EPD process pro-
vides low standoff voltages with significant reductions
in leakage currents and capacitance over silicon-
avalanche diode processes.
They may be used to meet the ESD immunity require-
ments of IEC 61000-4-2, Level 4 (±15kV air, ±8kV
contact discharge).
