onsemi ESD8011MUT5G

Overview

ESD8011MUT5G from onsemi is an ultra-low-capacitance bidirectional ESD protection diode in a 2-pin X3DFN2 package, rated for ±20 kV IEC 61000−4−2 contact/air discharge, with 0.10 pF typical junction capacitance, 5.5 V reverse working voltage, and 10.1 V clamping voltage at 8 A TLP-designed specifically to protect USB 3.x, SATA, and PCI Express high-speed data lines without signal integrity degradation.

For engineers reviewing the ESD8011MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include sub-0.2 pF capacitance, latch-up-free operation in USB 3.0 SuperSpeed interfaces, AEC-Q101 qualification, and verified IEC Level 4 ESD robustness-critical for high-data-rate serial link protection where insertion loss and timing skew must be minimized.

Technical Context

The ESD8011MUT5G employs a snap-back SCR-based structure optimized for high-speed differential signaling paths, delivering fast turn-on (sub-nanosecond response) and low dynamic resistance (1.0 Ω) to clamp transient energy before IC damage occurs. Its 0.3 nH series inductance and 0.10 pF capacitance preserve signal fidelity up to 10 GHz fundamental frequency, as validated by −0.256 dB insertion loss at 7.5 GHz (3rd harmonic of USB 3.0).

This device is explicitly characterized for latch-up–free operation in USB 2.0 HS/FS, USB 3.0 SS, and DisplayPort-confirmed via load-line analysis per AND9116/D-but excluded from HDMI TMDS due to insufficient VHOLD/IH margin. It meets AEC-Q101 stress requirements and supports automotive PPAP with SZ-prefix variant SZESD8011MUT5G*.

FAQ

What is the primary circuit role of the ESD8011MUT5G in a USB 3.x design?

The ESD8011MUT5G serves as a bidirectional transient voltage suppressor placed directly at the USB 3.x connector, clamping ESD pulses between the differential data line (Pin 1) and ground (Pin 2). Its 0.10 pF capacitance prevents signal integrity loss, while its 10.1 V clamping voltage at 8 A TLP ensures protected PHY pins remain within absolute maximum ratings. This role is confirmed in the datasheet's Typical Applications and Figure 1 insertion loss characterization for USB 3.0.

Is the ESD8011MUT5G qualified for automotive applications?

Yes-the ESD8011MUT5G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the datasheet Features section and Ordering Information table. The SZ-prefix variant SZESD8011MUT5G* is designated for automotive and other applications requiring unique site and control change requirements. Its operating junction temperature range (−55 °C to +125 °C) and qualification testing align with automotive environmental stress standards.

Why is the ESD8011MUT5G not recommended for HDMI applications?

The ESD8011MUT5G is excluded from HDMI TMDS use due to latch-up risk, as confirmed in the Latch-Up Considerations section and Table 1. Its holding voltage (VHOLD = 2.05 V) and holding current (IHOLD = 17 mA) fall below the minimum thresholds required for HDMI 1.4/1.3a (VH min = 1.0 V, IH min = 54.78 mA). Datasheet Figure 4 shows the load-line intersection that creates dual stable points-risking sustained conduction after ESD-so ESD8104 or ESD8040 are specified alternatives.

What does the "MUT5G" suffix indicate in ESD8011MUT5G?

The "MUT5G" suffix denotes the packaging and environmental compliance: "MU" indicates micro-packaged X3DFN2 (Case 152AF), "T5" specifies tape-and-reel packaging with 10,000 units per reel, and "G" certifies Pb-free, halogen-free/BFR-free, and RoHS-compliant construction. This is confirmed in the Ordering Information table on page 7 of the datasheet, where ESD8011MUT5G and SZESD8011MUT5G* share identical package and shipping details.

How does the ESD8011MUT5G achieve latch-up–free operation in USB 3.0 SuperSpeed?

The ESD8011MUT5G achieves latch-up–free operation in USB 3.0 SuperSpeed through precise SCR structure tuning-its VHOLD (2.05 V) and VBR (6.5–7.3 V) values ensure the IV curve intersects the USB 3.0 load line at only one stable point (VOP, IOP), preventing secondary conduction states. This is validated in Figure 4 and Table 1, which list USB 3.0 SS explicitly among latch-up–free applications, unlike HDMI TMDS where dual intersections occur.
