General Purpose ESD Protection - SP1003 Series
Description
Applications
Zener diodes fabricated in a proprietary silicon avalanche
technology protect each I/O pin to provide a high level of
protection for electronic equipment that may experience
destructive electrostatic discharges (ESD). These robust
diodes can safely absorb repetitive ESD strikes at ±30kV
(contact discharge, IEC 61000-4-2) without performance
degradation. Additionally, each diode can safely dissipate
7A of 8/20µs surge current (IEC61000-4-5) with very low
clamping voltages.
Features
• ESD, IEC61000-4-2,
±30kV contact, ±30kV air
• EFT, IEC61000-4-4, 40A
(5/50ns)
• Lightning, IEC61000-4-5,
7A (8/20µs)
• Low leakage current of
100nA (MAX) at 5V
• Tiny SOD723/ SOD882
(JEDEC MO-236) package
saves board space
• Fits solder footprint of
industry standard 0402
(1005) devices
• AEC-Q101 qualified
(SOD882 package)
• Mobile phones
• Smart phones
• PDAs
• Portable navigation
devices
• Digital cameras
• Portable medical devices
