The SFC05-4 is a quad flip chip TVS array. They are
state-of-the-art devices that utilize solid-state silicon-
avalanche technology for superior clamping perfor-
mance and DC electrical characteristics. The SFC
series TVS diodes are designed to protect sensitive
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. Flip
chip 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 flip chip design results in lower inductance, virtu-
ally eliminating voltage overshoot due to leads and
interconnecting bond wires. They may be used to meet
the ESD immunity requirements of IEC 61000-4-2,
Level 4 (±15kV air, ±8kV contact discharge).
