TVS Diode Arrays Prevent ESD Damage 0201 Size SP1026 Series

The SP1026 series TVS diode array from Littelfuse protects sensitive electronic equipment from damage due to electrostatic discharges (ESD). Zener diodes fabricated using a proprietary silicon avalanche technology protect each I/O pin to provide a high level of protection against ESD. These robust general-purpose diodes can safely absorb repetitive ESD strikes at ±30 kV without performance degradation. Additionally, each diode can safely dissipate 5 A of 8 / 20 μs surge current with very low clamping voltages. Applications include protection of mobile phones, smart phones, smart watches, tablets, portable navigation devices, and portable medical devices.
