Product details
Overview
ESD8704MUTAG from onsemi is a low-capacitance quad-channel ESD protection diode array designed for high-speed differential data lines. It delivers 0.30 pF typical junction capacitance at 1 MHz, ±30 kV IEC 61000-4-2 contact/air ESD rating, and 4.7 V clamping voltage at 8 A TLP, enabling robust protection of USB 3.0/3.1, eSATA, and DisplayPort interfaces without signal integrity degradation.
For engineers reviewing the ESD8704MUTAG datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance (≤0.5 pF), latch-up-free operation in USB 3.0/3.1 and DisplayPort, flow-through UDFN10 package layout compatibility, and verified IEC 61000-4-2 Level 4 compliance.
Technical Context
The ESD8704MUTAG employs a snap-back SCR-based protection structure optimized for high-speed serial interfaces. Its 0.5 pF max capacitance ensures minimal signal distortion up to 10 Gb/s (5 GHz fundamental), while its 3.3 V reverse working voltage and 1.9 V holding voltage enable safe operation with 3.3 V I/O rails.
Designed specifically for differential pair routing, the flow-through UDFN10 package places I/O pins 1–2 and 4–5 on opposite edges to support matched trace lengths and consistent impedance control. The device is qualified to AEC-Q101 and supports Pb-free, halogen-free manufacturing.

| Operating Temp Range | −55 °C to +125 °C - supports industrial and automotive under-hood environments |
Pinout & Package
ESD8704MUTAG uses the UDFN10 (Case 517BB) 2.5 mm × 1.0 mm, 0.5 mm pitch wettable flank package. Its flow-through layout minimizes stub length and enables symmetric routing for differential pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Channel A+ | Input/output terminal for first differential line (e.g., USB3 TX+) |
| 2 | I/O Channel A− | Input/output terminal for first differential line (e.g., USB3 TX−) |
| 3 | GND | Common cathode connection; minimum one GND required for SCR operation |
| 4 | I/O Channel B+ | Input/output terminal for second differential line (e.g., USB3 RX+) |
| 5 | I/O Channel B− | Input/output terminal for second differential line (e.g., USB3 RX−) |
| 6–7, 9–10 | N/C | No internal connection - electrically isolated, may be used as thermal pads or left floating |
| 8 | GND | Second GND terminal - improves thermal dissipation and grounding path redundancy |
Key Features

Use Value: Enables full compliance with IEC 61000-4-2 Level 4 (±30 kV) while adding <0.05 mm of PCB footprint per channel. |
| DisplayPort Source Protection | Industrial High-Speed Serial Link Protection |
Use Scenario: Shielding DisplayPort 1.2/1.4 source outputs (main link lanes) in monitors, docking stations, and graphics adapters. IC Role / Device Role / Timing Role: Quad-channel ESD suppressor aligned with DP's four main link differential pairs - placed adjacent to edge connectors per layout guidelines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD8006MUTAG | 0.35 pF max capacitance; identical UDFN10 package and 3.3 V VRWM | Qualified for both USB 3.0/3.1 and DisplayPort; same latch-up behavior | Select when dual-source availability or alternate supply chain validation is required |
| ESD8104MUTAG | 0.50 pF max capacitance; higher VHOLD (2.5 V); rated for HDMI TMDS | Required for HDMI 1.4/1.3a due to stricter latch-up margin; not recommended for USB 3.0 | Choose only for HDMI applications - ESD8704MUTAG is superior for USB/DP due to lower capacitance and proven latch-up immunity |
Compared with ESD8006MUTAG, ESD8704MUTAG offers lower typical capacitance (0.30 vs. 0.35 pF) and tighter clamping (4.7 V vs. 5.0 V @ 8 A), making it preferred for 10 Gb/s USB 3.1 Gen 2. Against ESD8104MUTAG, ESD8704MUTAG provides better high-frequency signal fidelity and is explicitly validated for USB/DP - whereas ESD8104MUTAG targets HDMI-specific latch-up margins.

FAQ
What is the maximum junction capacitance of ESD8704MUTAG and at what frequency is it specified?
The maximum junction capacitance of ESD8704MUTAG is 0.50 pF, measured between I/O pins and GND at VR = 0 V and f = 1 MHz. At higher frequencies - 2.5 GHz (USB 3.0 fundamental) and 5.0 GHz (USB 3.1 fundamental) - capacitance drops to 0.40 pF and 0.25 pF respectively, ensuring minimal impact on 5–10 Gb/s signal integrity. This frequency-dependent behavior is confirmed in Figure 10 of the official datasheet.
Is ESD8704MUTAG suitable for HDMI 1.4/1.3a TMDS applications?
No, ESD8704MUTAG is not recommended for HDMI 1.4/1.3a TMDS applications. Datasheet Table 1 explicitly lists HDMI as a "Potential Latch-up" use case for ESD8704MUTAG due to insufficient holding voltage margin. For HDMI, onsemi specifies ESD8104 or ESD8040 - devices with higher VHOLD (2.5 V) and optimized SCR parameters. Using ESD8704MUTAG in HDMI may result in latch-up and permanent failure.
What package type and dimensions does ESD8704MUTAG use?
ESD8704MUTAG uses the UDFN10 package (Case 517BB), measuring 2.5 mm × 1.0 mm with 0.5 mm pitch. It features wettable flank terminations for AOI compatibility and an exposed copper thermal pad. Pin 1 marking is indicated by a microdot or "7D" laser marking. Mechanical drawings confirm body thickness of 0.45–0.55 mm and terminal coplanarity ≤0.10 mm - critical for reliable reflow soldering.
Does ESD8704MUTAG require multiple ground connections for proper operation?
No, ESD8704MUTAG requires only a minimum of one GND connection (Pin 3 or Pin 8) for functional SCR operation, as stated in the datasheet pin configuration note. However, connecting both GND pins (3 and 8) is strongly recommended to reduce dynamic resistance, improve thermal dissipation, and enhance ESD current shunting capability - especially in high-reliability or high-power transient scenarios.
What is the clamping voltage performance of ESD8704MUTAG under IEC 61000-4-2 testing?
ESD8704MUTAG does not specify a single clamping voltage under IEC 61000-4-2 because the standard defines pass/fail criteria, not device-level clamping. Instead, datasheet Figures 1–2 show oscilloscope waveforms demonstrating clamping at ~8–10 V peak during ±8 kV contact discharge. For design purposes, the TLP-derived clamping voltage of 4.7 V @ 8 A (positive) and −4.0 V @ 8 A (negative) is the validated, repeatable metric used for circuit protection analysis in ESD8704MUTAG applications.
