Littelfuse, the world's leading provider of circuit protection solutions, today announced the SP1026 family of 15pF 30kV bidirectional discrete TVS diode arrays designed to protect sensitive electronic equipment from electrostatic discharge (ESD) damage. Zener diodes fabricated using proprietary silicon avalanche technology protect each input/output pin and provide high electrostatic discharge (ESD) protection for the device. This powerful, versatile diode safely absorbs repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) with no degradation in performance. In addition, each diode can safely dissipate 5A of 8/20μs waveform inrush current (IEC61000-4-5) at very low clamping voltages.

Applications for the SP1026 family of diodes include protecting mobile phones, smartphones, smart watches, tablets, portable navigation devices and portable medical devices.
“The SP1026 family complements our portfolio of general purpose ESD protection devices,†said Tim Micun, Product Manager, Transient Suppression Diode Array (SPA® Diode). “This product provides a cost-effective solution for design engineers, and a space-efficient design can easily fit into the increasingly dense board layout of components.
All SP1026 series of TVS diodes offer the following key benefits:
• This space-efficient ESD solution occupies only 0201 size (0.60mm x 0.30-5mm) space, saving PCB space and reducing costs.
• Very low dynamic resistance (1.4Ω) supports the low clamping voltage required to protect modern electronics filled with small form factor integrated circuits.
• Provides high ESD immunity and superior protection (ESD, IEC 61000-4-2, ±30kV contact, ±30kV air discharge; EFT, IEC 61000-4-4, 40A (5/50ns); lightning strike, IEC 61000 -4-5 2nd Edition, 5A (tP=8/20μs), allows manufacturers to offer products with ESD protection performance that exceeds the highest level of IEC standards, and addresses many other threats to ensure product reliability in actual use.
