Littelfuse SP11xx Discrete Unidirectional TVS Diodes

Littelfuse SP11xx Discrete Unidirectional TVS Diodes are fabricated in a proprietary silicon avalanche technology to protect each I/O pin and provide a high level of protection for electronic equipment against electrostatic discharges (ESD). These robust diodes can safely absorb repetitive ESD strikes at ±30kV (contact and air discharge, EIC 61000-4-2) without performance degradation. Each Littelfuse SP11xx diode can safely dissipate 80A (SP1105S) of 8/20µs surge current (IEC 61000-4-5 2nd edition) with very low clamping voltages.

Features

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