Product details
Overview
SZESD8704MTWTAG from onsemi is an automotive-grade, low-capacitance ESD protection diode array in a wettable flank WDFNW10 package, designed for high-speed differential data lines including USB 3.0/3.1 (5–10 Gb/s), eSATA, and DisplayPort. It delivers 0.30 pF typical junction capacitance at 1 MHz, ±30 kV IEC 61000−4−2 contact ESD immunity, and 4.7 V clamping voltage at 8 A TLP, enabling signal integrity preservation in voltage-sensitive interfaces.
For engineers reviewing the SZESD8704MTWTAG datasheet, pinout, applications, or equivalent options, this device is selected for high-speed serial interface protection where ultra-low capacitance, AEC-Q101 qualification, wettable flank AOI compatibility, and latch-up-free operation in USB 3.0/3.1 and DisplayPort are mandatory design requirements.
Technical Context
The SZESD8704MTWTAG integrates four independent bidirectional ESD protection channels in a single flow-through WDFNW10 package, with common GND connection and no internal connections to pins 3, 6, 7, 9. Its snap-back SCR structure provides low dynamic resistance (0.30 Ω) and fast response to IEC 61000−4−2 transients while maintaining latch-up immunity in USB 3.0/3.1 and DisplayPort applications per load-line analysis.
It operates across −55 °C to +125 °C junction temperature, supports 3.3 V working peak voltage, and achieves 6.0 V breakdown voltage (min) at 1 mA. The device's 0.31 pF capacitance at 5 GHz ensures minimal insertion loss (−0.09 dB at 2.5 GHz fundamental) and preserves 5–10 Gb/s eye diagrams without degradation.

FAQ
What is the primary function of the SZESD8704MTWTAG in a high-speed data interface?
The SZESD8704MTWTAG functions as a four-channel bidirectional ESD protection diode array that clamps transient overvoltages on high-speed differential lines such as USB 3.0/3.1 and DisplayPort. It operates with ultra-low 0.30 pF capacitance to avoid signal degradation while delivering ±30 kV IEC 61000−4−2 contact ESD protection and 4.7 V clamping at 8 A TLP-ensuring robust, signal-transparent protection for the SZESD8704MTWTAG's target applications.
Does the SZESD8704MTWTAG support automotive production requirements?
Yes, the SZESD8704MTWTAG is AEC-Q101 qualified, PPAP capable, and features a wettable flank WDFNW10 package for automated optical inspection-meeting critical automotive manufacturing requirements. Its latch-up immunity has been verified for USB 3.0/3.1 and DisplayPort interfaces, and it operates across −55 °C to +125 °C junction temperature, making the SZESD8704MTWTAG suitable for automotive infotainment and ADAS data links.
How does the flow-through pinout of the SZESD8704MTWTAG benefit PCB layout?
The SZESD8704MTWTAG's flow-through pin configuration (I/O–I/O–NC–I/O–I/O–NC–NC–GND–NC–GND) allows straight-through routing of differential pairs with matched trace lengths-preserving impedance continuity and minimizing skew. This layout advantage directly supports USB 3.0/3.1 and DisplayPort signal integrity requirements and reduces design iteration time for the SZESD8704MTWTAG in high-density PCBs.
What is the maximum clamping voltage of the SZESD8704MTWTAG under real-world ESD stress?
The SZESD8704MTWTAG achieves a clamping voltage of 4.7 V at 8 A TLP (transmission line pulse) and 6.6 V at 16 A TLP for positive polarity, with corresponding values of −4.0 V and −6.7 V for negative polarity. These values-measured per IEC 61000−4−2 waveform equivalents-represent the actual voltage seen by protected ICs during ESD events, confirming the SZESD8704MTWTAG's ability to safeguard 3.3 V I/O structures.
Can the SZESD8704MTWTAG be used in HDMI applications?
No, the SZESD8704MTWTAG is not recommended for HDMI applications due to potential latch-up risk in TMDS lines, as confirmed in the official datasheet (Table 1 and latch-up analysis on page 8). For HDMI 1.4/1.3a, onsemi specifies ESD8104 or ESD8040 instead. The SZESD8704MTWTAG is explicitly validated only for USB 2.0/3.0/3.1, DisplayPort, and eSATA-using its specified load-line characteristics.
