Product details
Overview
SZESD8011MUT5G from onsemi is an ultra-low-capacitance bidirectional ESD protection diode designed for high-speed data lines, featuring 0.10 pF typical junction capacitance, 5.5 V reverse working voltage, and ±20 kV IEC 61000−4−2 contact/air ESD rating - deployed in USB 3.x, SATA, and PCI Express interfaces.
For engineers reviewing the SZESD8011MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 8 A (10.1 V), latch-up immunity for USB 3.0 SuperSpeed, dynamic resistance (1.0 Ω), and X3DFN2 package compatibility with high-density PCB layouts.
Technical Context
The SZESD8011MUT5G uses a snap-back SCR-based structure optimized for transient suppression without latch-up in USB 3.0, DisplayPort, and SATA applications - confirmed by load-line analysis showing single stable operating point (VOP/IOP) under normal bias conditions.
It delivers bidirectional protection with symmetrical clamping behavior (VC = 10.1 V @ IPP = 8 A, 17.2 V @ IPP = 16 A), low dynamic resistance (1.0 Ω), and sub-0.3 nH series inductance to preserve signal integrity up to 5 Gb/s (USB 3.0 fundamental at 2.5 GHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.5 V - ensures safe operation across 3.3 V and 5 V data line rails without leakage-induced signal distortion |
| Junction Capacitance | 0.10 pF (typ) - minimizes insertion loss and preserves eye diagram integrity in 5 Gb/s USB 3.0 channels |
| ESD Rating | ±20 kV (IEC 61000−4−2 contact/air) - meets Level 4 immunity for industrial and automotive interface ports |
| Clamping Voltage | 10.1 V @ 8 A TLP - limits transient overvoltage to protect downstream PHY receivers during ESD events |
| Dynamic Resistance | 1.0 Ω - enables fast voltage clamping response with minimal IR drop during high-current transients |
| Operating Temperature | −55 °C to +125 °C - supports extended-range deployment in automotive infotainment and industrial control systems |

|---|---|---|
| Pin 1 | I/O Terminal | Bidirectional ESD protection node connected to high-speed data line (e.g., USB 3.0 TX+/RX+) |
| Pin 2 | GND | Low-inductance return path for transient current; must be tied directly to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.10 pF typ - avoids signal degradation in >5 Gb/s serial links (USB 3.0, SATA III) |
| Latch-up immunity | Validated for USB 3.0 SuperSpeed, DisplayPort, and SATA - no false triggering or sustained conduction |
| AEC-Q101 qualification | Automotive-grade reliability with PPAP support - suitable for infotainment and ADAS data interfaces |
| SCR-based snap-back architecture | Enables low clamping voltage (10.1 V @ 8 A) while maintaining robust surge handling (3.6 A peak pulse) |
Applications
| USB 3.x Interface Protection | SATA/SAS Data Line Protection |
|---|---|
Use Scenario: Protecting differential TX/RX pairs in host/device USB 3.0/3.1 Gen1 ports against ESD events during hot-plug or system handling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed immediately adjacent to connector, shunting ESD energy to ground before reaching USB PHY. Use Value: 0.10 pF capacitance prevents eye closure; 10.1 V clamping ensures PHY input stays below absolute maximum rating (typically 12 V). | Use Scenario: Safeguarding SATA III 6 Gb/s differential lanes in storage controllers and SSD modules exposed to board-level ESD. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on each lane (TXP/TXN/RXP/RXN), mounted within 3 mm of connector per layout guidelines. Use Value: Sub-0.3 nH inductance and 1.0 Ω dynamic resistance enable effective clamping within <1 ns, preserving jitter budget. |
| PCI Express Gen2/Gen3 Lane Protection | MHL 2.0 Mobile Display Interface |
Use Scenario: ESD hardening of PCIe x1/x4 slots in embedded computing platforms and industrial gateways where connectors are user-accessible. IC Role / Device Role / Timing Role: Per-lane protection device on each differential pair, leveraging symmetric clamping to maintain common-mode noise rejection. Use Value: ±20 kV IEC 61000−4−2 rating exceeds PCIe CEM specification requirements; 5.5 V VRWM aligns with 3.3 V PCIe rail. | Use Scenario: Protecting MHL 2.0 superMHL sideband channel (SBC) and main link in smartphone-to-dock interfaces subject to frequent cable insertion. IC Role / Device Role / Timing Role: Ultra-compact ESD suppressor on 3.3 V–biased differential video/data lines, placed before level-shifting circuitry. Use Value: X3DFN2 footprint (0.62 × 0.32 mm) fits tight mobile PCB real estate; 0.10 pF capacitance avoids MHL 2.0 3 Gb/s eye mask violations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD8004MUT5G | Higher capacitance (0.35 pF typ), lower VRWM (3.3 V), same X3DFN2 package | Optimized for USB 2.0 HS/FS; not recommended for >480 Mbps due to bandwidth limitation | Select when protecting 480 Mbps or lower-speed interfaces where tighter voltage margin is required |
| ESD8006MUT5G | 0.15 pF capacitance, 5.5 V VRWM, higher clamping (12.5 V @ 8 A), same footprint | Validated for DisplayPort and SATA but not USB 3.0 due to marginal latch-up margin | Prefer for DisplayPort 1.2a or SATA III where slightly higher clamping is acceptable for improved robustness |
Compared with ESD8004MUT5G and ESD8006MUT5G, the SZESD8011MUT5G offers the lowest capacitance (0.10 pF) and best latch-up immunity for USB 3.0 SuperSpeed, making it the optimal choice when signal integrity at 5 Gb/s and guaranteed non-latching behavior are mandatory.

FAQ
What is the maximum clamping voltage of the SZESD8011MUT5G at 8 A TLP current?
The SZESD8011MUT5G has a clamping voltage of 10.1 V at 8 A TLP current (IEC 61000−4−2 Level 2 equivalent). This value is measured under Transmission Line Pulse conditions (Z₀ = 50 Ω, tₚ = 100 ns) and reflects the peak voltage seen by protected circuitry during an ESD event. The SZESD8011MUT5G maintains this performance across its full operating temperature range (−55 °C to +125 °C).
Is the SZESD8011MUT5G qualified for automotive applications?
Yes, the SZESD8011MUT5G carries the "SZ" prefix indicating AEC-Q101 qualification and PPAP capability. It is rated for −55 °C to +125 °C junction temperature and designed for automotive infotainment, telematics, and ADAS data interfaces where ESD robustness and long-term reliability are critical. The SZESD8011MUT5G meets all stress test requirements defined in AEC-Q101 Rev D.
Can the SZESD8011MUT5G be used to protect HDMI interfaces?
No, the SZESD8011MUT5G is not recommended for HDMI TMDS lines due to latch-up risk under HDMI 1.3a/1.4 operating conditions. Application Note AND9116/D confirms that ESD8104 or ESD8040 are the validated alternatives for HDMI. The SZESD8011MUT5G's SCR characteristics intersect the HDMI load line at two points, creating potential for sustained conduction after transient events.
What is the package type and dimensions of the SZESD8011MUT5G?
The SZESD8011MUT5G is housed in the X3DFN2 package (Case 152AF), measuring 0.62 mm × 0.32 mm × 0.24 mm with 0.35 mm pin pitch. It features wettable flanks for automated optical inspection and is Pb-free, halogen-free, and RoHS-compliant. The marking code appears rotated 90° clockwise, with "R" denoting the specific device code and "M" the date code.
Does the SZESD8011MUT5G support bidirectional ESD protection?
Yes, the SZESD8011MUT5G provides symmetrical bidirectional protection between Pin 1 (I/O) and Pin 2 (GND), with identical clamping performance for positive and negative transients. Its SCR-based snap-back structure ensures matched turn-on voltage and clamping behavior in both directions - verified by separate positive and negative TLP IV curves in the official datasheet.
