Littelfuse, Inc., a global leader in circuit protection solutions, has recently launched a new family of compact TVS diode arrays known as the SP3422-04UTG Series. These ultra-small devices are specifically designed to offer high-speed signal pin protection while maintaining excellent electrical performance. The SP3422-04UTG combines a four-channel, ultra-low capacitance rail-to-rail TVS diode with an additional Zener diode, providing reliable ESD protection for sensitive electronic components.
Engineered to meet the highest standards, this advanced component can safely absorb repeated ESD strikes up to the maximum level defined by the IEC61000-4-2 international standard without any loss in performance. This makes it ideal for use in today’s increasingly complex and high-speed electronic systems.
The SP3422-04UTG series is particularly well-suited for applications such as V-by-One interfaces, USB 3.0, USB 2.0, IEEE 1394, MIPI camera and display interfaces, embedded DisplayPort, and other serial bus connections. It also finds use in flat panel displays, LCD/LED TVs, and mobile computing devices like smartphones, where space is at a premium.
“Thanks to its compact design—just one-third the size of a traditional four-line array—the SP3422-04UTG allows for direct PCB routing, eliminating signal integrity issues caused by fan-out,†said Timticic, Littelfuse's Transient Diode Array Business Development Manager. “Its small form factor combined with the lowest load capacitance available in this package makes it perfect for mobile devices that require minimal board space.â€
Key advantages of the SP3422-04UTG series include:
- Provides ESD protection for four lines in a smaller package than traditional SOD-882 configurations, offering significant space savings compared to discrete or dual-channel solutions.
- Direct connection to PCB pins ensures no signal degradation and eliminates the need for fan-out routing.
- Ultra-low parasitic capacitance (typically 0.2pF) preserves signal integrity, making it ideal for high-speed interfaces like USB 3.0, MIPI, and DisplayPort.
- Designed for automotive-grade reliability, it operates effectively across a wide temperature range and maintains performance even in harsh environments.
With its combination of compact size, high performance, and robust protection capabilities, the SP3422-04UTG series is a game-changer for engineers working on next-generation electronic designs.
