SP1124 Datasheet Discrete Unidirectional Tvs Diode

Manufacturer: Littelfuse

Overview: TVS Diode Arrays (SPA®®Diodes) General Purpose Surge Protection - SP11xx Series SP11xx Series Discrete Unidirectional TVS Diode RoHS Pb.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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 and air discharge, IEC 61000-4-2) without performance degradation.

Additionally, each diode can safely dissipate 80A (SP1105S) of 8/20μs surge current (IEC 61000-4-5 2nd edition) with very low clamping voltages.

Key Features

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air.
