Płyta msi z270 gaming m7 - Prośba o identyfikację elementów

Prześledziłem cały schemat płyty i znalazłem 3 rodzaje układów 6-nóżkowych, jednak analizując najbardziej pasujący jest element o nazwie NN-HBN2515S6R z dwóch powodów: zgodnie z schematem nóżka 1 jest zwarta z nóżką 4 do masy co zgadzało by się z pomiarami oraz na schemacie znajdują się 3 takie elementy co ma odzwierciedlenie na płycie, gdyż doszukałem się właśnie jedynie 2 + domniemany 3 którego brakuje. Analizując dalej schemat sprawdziłem, że owe NN-HBN2515S6R łączą się z złączami audio, a więc odpowiadają za dźwięk. Więc pytanie czy bez tego płyta wystartuje i jedynie porty audio nie będą działać poprawnie czy może to nieść jakieś konsekwencje ?


AOZ8906
Ultra-Low Capacitance TVS Diode Array

General Description

Features

The AOZ8906 is a transient voltage suppressor array
designed to protect high speed data lines such as HDMI,
USB 2.0, MDDI, SATA, and Gigabit Ethernet from
damaging ESD events.

? ESD protection for high-speed data lines:

This device incorporates eight surge rated, low
capacitance steering diodes and a TVS in a single
package. During transient conditions, the steering diodes
direct the transient to either the positive side of the power
supply line or to ground.
The AOZ8906 provides a typical line to line capacitance
of 1pF making it ideally suited for HDMI 1.3 or USB 2.0
applications, such as Digital TVs,
DVD players, Computing, set-top boxes and MDDI
applications in mobile computing devices.
The AOZ8906 comes in RoHS compliant and halogen
free SOT23-6L package and is rated -40°C to +85°C
junction temperature range.

- IEC 61000-4-2, level 4 (ESD) immunity test
- ?30kV (air discharge) and ?30kV (contact discharge)
- IEC61000-4-4 (EFT) 40A (5/50nS)
- IEC61000-4-5 (Lightning) 7A (8/20uS)
- Human Body Model (HBM) ?30kV
? Array of surge rated diodes with internal TVS diode
? Protects four I/O lines
? Low capacitance between I/O lines: 1pF
? Low clamping voltage
? Low operating voltage: 5.0V

Applications
? HDMI, USB 2.0, MDDI, SATA ports
? Monitors and flat panel displays
? Set-top box
? Video graphics cards
? Notebook computers
