Littelfuse Introduces Two Series of 0.5pF, 12kV TVS Diode Arrays

CHICAGO, IL -- Littelfuse, Inc. introduces two series of TVS Diode Arrays (SPA® Diodes) designed to safeguard many of the latest high-speed interfaces from damage due to electrostatic discharges (ESD).

SP7538P Series TVS Diode Arrays integrate eight channels of ultra-low capacitance rail-to-rail diodes and an additional zener diode in a µDFN-9 package; SP0544T Series TVS Diode Arrays have a similar design but are smaller, with four channels of ultra-low capacitance rail-to-rail diodes instead of eight. Both of these robust device series can safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (±8kV contact discharge) without performance degradation. Their extremely low loading capacitance also makes them ideal for protecting high-speed signal pins.

Typical applications for both series include ESD protection for interfaces like V-by-One, Embedded DisplayPort, USB 2.0/3.0 Ports, and HDMI, as well as flat panel displays, LCD/LED TVs, smartphones and mobile computing.

SP7538P and SP0544T Series TVS Diodes offer these key benefits:
• Their extremely low loading capacitance of 0.5pF (typ) per I/O reduces signal degradation and distortion for high-speed applications.
• They offer low dynamic resistance (0.4Ω), which provides low clamping performance to ensure better protection for sensitive chipsets.
• Their enhanced ESD capability (±12kV contact, ±25kV air) permits manufacturers to achieve ESD protection beyond the maximum level stated in the IEC standard and protects against a multitude of other threats to ensure product reliability in the field.

Availability

The SP7538P Series is packaged in a μDFN-9 package; the SP0544T Series comes in a μDFN-10 package. Both are provided in tape & reel packaging in quantities of 3,000. Sample requests can be placed through authorized Littelfuse distributors worldwide.
