Littelfuse TVS Diode Arrays Provide Ultimate Ultra-Low Capacitance Protection from ESD for Ultra High-Speed Interfaces

AEC-Q101-qualified devices outperform polymer-based technologies and spark gaps

Beijing, China, May8, 2019 —Littelfuse, Inc.today introduced two series of bidirectional TVS Diode Arrays (SPA® Diodes) designed to protect ultra high speed consumer electronics interfaces from damaging electrostatic discharge (ESD) in applications where PCB layout is especially challenging. The SP3208-01UTG, the first TVS Diode Array in the SP3208 Series, is mechanically optimized to deliver consistently ultra-low capacitance (nominally 0.08 pF). The SP3213-01UTG, the first SP3213 Series device, offers an option for highly cost-conscious ESD protection solutions.
SP3208-and-SP3213-Sereis-TVS-Diode-ArraysnceBoth of these “Ultimate Ultra-Low Capacitance ESD Protection” devices are AEC-Q101-qualified, employ the same base die, and can safely absorb repetitive ESD strikes at ±12 kV without performance degradation and dissipate 2 A of 8/20 μs surge current.
Typical applications for SP3208 and SP3213 Series TVS Diode Arrays include:
• Ultra-high speed data lines and interfaces, such as USB 3.2, 3.1, 3.0, 2.0, HDMI 2.1. 2.0, 1.4a, 1.3, DisplayPort™, Thunderbolt and V-by-One®,
• Low power antenna ports,
• Consumer, mobile and portable electronics, and
• Tablet PCs and external storage with high speed interfaces.
“Rising data rate speeds present significant challenges to design engineers who need to maintain high signal integrity,” said Tim Micun, Business Development Manager, TVS Diode Arrays (SPA Diodes) at Littelfuse. “Compared to other ESD protection solutions on the market, the SP3208 and SP3213 Series provide 50 percent lower nominal capacitance, which helps preserve signal integrity and minimize data loss. Providing a passband in excess of 30 GHz allows signal integrity engineers to create a high speed, data capable environment.”
SP3208 and SP3213 Series TVS Diode Arrays offer these key benefits:
• Sub-0.1 pF silicon-based ESD protection allows for passbands as high as 30 GHz, enabling high signal integrity for the world’s fastest data interfaces.
• Industry-standard 0201DFN packaging with internal construction enhancements reduce parasitic capacitance, inductance, and resistance, making these TVS Diode Arrays easier to model into a protection scheme.
• Lower parasitic capacitance and inductance permit better dynamic resistance performance, protecting the circuit faster and better.

TE Connectivity Announced Ultra Small Spring Fingers

TE Connectivity (TE)’snew ultra small spring fingers have one of the smallest footprints in the market to save valuable PCB space, allowing for use in a broad range of applications with space constraints across various industries.TE’s ultra small spring fingerscan save valuable PCB space with one of the smallest footprints in the market. Closed-loop contact design ensures reliable connection to the PCB, better normal force and higher current capacity (1.5A). Robust side wall minimizes over- compression. Special anti-lifting design can improve assembly e ciency by locking the tip of the contact within the sidewall of the spring  nger, which helps prevent the contact from getting caught on an operator’s glove during assembly. Pick-and-place area supports auto-assembly processes. It also offered in different heights and styles.As an authorized distributor for TE Connectivity, Heilind Asia provides TE’s products and also value added services. Heilind Asia supports both original equipment …
