Littelfuse SP4315-01WTG TVS Diode Array
Littelfuse SP4315-01WTG Transient Voltage Suppressor (TVS) Diode Array features ultra-low capacitance, a bidirectional design, and protection for electronic equipment susceptible to destructive electrostatic discharges (ESD). This SPA® diode offers a typical capacitance of 0.17pF to ensure excellent signal integrity and provide robust circuit protection. The module safely absorbs repetitive ESD strikes at ±15kV (contact discharge, IEC 61000-4-2) without compromising performance and withstands electrical fast transient (EFT) events of 40A (5/50ns) (IEC 61000-4-4). Littelfuse SP4315-01WTG TVS Diode Array also safely dissipates 7A of 8/20μs surge current (IEC 61000-4-5 2nd edition). This device is ideal for high-speed Ethernet and consumer electronics interfaces, such as DisplayPort, Thunderbolt, USB 3x, USB 4.0, and low-voltage differential signaling (LVDS).
