SP1003 Series

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

±30kV contact, ±30kV air
