TVS Diode Array (SPA ® Diodes)
Revision: 12/05/18
General Purpose ESD Protection - SD-C Series
Description
Applications
The SD-C series can safely absorb repetitive ESD strikes
at ±30kV (contact discharge, IEC 61000-4-2) without
performance degradation and safely dissipate 30A (SD05C)
of 8/20μs induced surge current (IEC 61000-4-5 2ND Edition)
with very low clamping voltages.
Features
• ESD, IEC 61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC 61000-4-4, 40A
(5/50ns)
• Lightning, 30A (8/20 as
defined in IEC 61000-4-5
2nd edition) SD05C
• Low clamping voltage
• Low leakage current
• Small SOD323 package
fits 0805 footprints
• AEC-Q101 qualified
• RoHS Compliant and
Lead Free
• Moisture Sensitivity Level
(MSL-1)
• Switches / Buttons
Test Equipment /
Instrumentation
Point-of-Sale Terminals
• Medical Equipment
• Notebooks / Desktops /
Servers
• Computer Peripherals
