onsemi SZESD8704MUTAG

Overview

SZESD8704MUTAG from onsemi is an ultra-low-capacitance ESD protection diode array designed for high-speed differential data lines including USB 3.0/3.1 and DisplayPort. It delivers 0.30 pF typical junction capacitance at 1 MHz, ±30 kV IEC 61000−4−2 contact ESD protection, and 4.7 V clamping voltage at 8 A TLP, enabling signal integrity preservation in 5–10 Gb/s interfaces.

For engineers reviewing the SZESD8704MUTAG datasheet, pinout, applications, or equivalent options, key selection criteria include low dynamic resistance (0.30 Ω), latch-up-free operation in USB 3.0/3.1 and DisplayPort, wettable flank UDFN10 package compatibility with AOI, and verified 5.0 V breakdown voltage per I/O-to-GND path.

Technical Context

The SZESD8704MUTAG uses a snap-back SCR structure optimized for high-speed serial interfaces, with clamping behavior characterized via TLP testing at 8 A and 16 A pulses. Its flow-through UDFN10 layout supports matched trace routing for differential pairs while minimizing parasitic inductance.

It operates across −55 °C to +125 °C junction temperature, meets AEC-Q101 for automotive use, and features Pb-free, halogen-free construction compliant with RoHS. The device is rated for ±30 kV IEC 61000−4−2 contact discharge and exhibits no latch-up in USB 3.0/3.1 or DisplayPort applications when placed per recommended layout guidelines.

FAQ

What is the maximum clamping voltage of SZESD8704MUTAG under IEC 61000−4−2 contact discharge?

The SZESD8704MUTAG does not specify a single maximum clamping voltage for IEC 61000−4−2 contact discharge in its datasheet; instead, it provides oscilloscope waveforms (Figures 1–2) showing clamping below 12 V for ±8 kV events. Its TLP-derived clamping is 4.7 V at 8 A and 6.6 V at 16 A, which correlates to robust protection for 3.3 V I/O rails. This performance is confirmed in the Electrical Characteristics table and Figure 5–6 I–V curves for SZESD8704MUTAG.

Is SZESD8704MUTAG suitable for HDMI 2.0 applications?

No, SZESD8704MUTAG is not recommended for HDMI 2.0 applications. The datasheet explicitly states potential latch-up in HDMI 1.4/1.3a TMDS interfaces due to load-line intersection characteristics of its SCR structure. For HDMI, onsemi recommends ESD8104 or ESD8040 - devices validated for latch-up-free operation. SZESD8704MUTAG is qualified only for USB 2.0/3.0/3.1, DisplayPort, and eSATA per Table 1 and latch-up analysis on page 8.

What is the meaning of "SZ" prefix in SZESD8704MUTAG?

The "SZ" prefix in SZESD8704MUTAG denotes automotive-grade qualification and unique site/control change requirements. It signifies AEC-Q101 qualification, PPAP capability, and manufacturing traceability aligned with automotive quality standards. This distinguishes SZESD8704MUTAG from the commercial-grade ESD8704MUTAG variant, though both share identical electrical specs and UDFN10 packaging. All SZESD8704MUTAG units meet the same 0.30 pF capacitance and ±30 kV ESD rating.

Does SZESD8704MUTAG require external biasing or control signals?

No, SZESD8704MUTAG is a passive, bidirectional ESD protection diode array requiring no external biasing, control signals, or power supply. It operates solely through avalanche and snap-back conduction between I/O pins and GND. Its SCR-based structure triggers automatically during ESD transients above ~5 V, clamping excess energy to ground without any active circuitry - a key feature confirmed in the Functional Description and Latch-Up Considerations sections of the SZESD8704MUTAG datasheet.

How does the UDFN10 package of SZESD8704MUTAG support high-speed layout?

The UDFN10 package of SZESD8704MUTAG features a flow-through pinout (Pins 1–2–4–5 as I/O, Pins 3/8 as GND) that enables straight, symmetric trace routing for differential pairs - critical for maintaining 90 Ω differential impedance and minimizing skew. Its 2.5 × 1.0 mm footprint and wettable flanks allow for AOI-verified solder joints and reduced parasitic inductance versus larger packages. This layout advantage is documented in Figure 14 and the PCB Layout Guidelines section specific to SZESD8704MUTAG.
