TVS Diode Arrays (SPA® Devices)
Revision: December 19, 2012
SD05C Series
SD05C
General Purpose ESD Protection - SD05C Series
Description
Applications
The bidirectional SD05C TVS diode is designed to replace
multilayer varistors (MLVs) in electronic equipment for low
speed and DC applications. It will protect any sensitive
equipment from damage due to electrostatic discharge
(ESD) and other transient events.
The SD05C can safely absorb repetitive ESD strikes
at ±30kV (contact discharge, IEC 61000-4-2) without
performance degradation and safely dissipate 30A of
8/20μs induced surge current (IEC61000-4-5) with very low
clamping voltages.
Features
• ESD, IEC61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC61000-4-4, 50A
(5/50ns)
• Lightning, IEC61000-4-5,
30A (tP=8/20μs)
• Low clamping voltage
• Low leakage current
• Small SOD323 package
fits 0805 footprints
• Switches / Buttons
• Test Equipment /
Instrumentation
• Point-of-Sale Terminals
• Medical Equipment
• Notebooks / Desktops /
Servers
• Computer Peripherals
