Product details
Overview
ESD8451MUT5G from onsemi is a low-capacitance bidirectional ESD protection diode designed for high-speed data lines including USB 3.0, MHL 2.0, and eSATA interfaces. It features 0.30 pF max junction capacitance at 1 MHz, 3.3 V reverse working voltage, 13.7 V clamping voltage at 3.7 A (8/20 µs), and AEC-Q101 qualification for automotive applications.
For engineers reviewing the ESD8451MUT5G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance for signal integrity, IEC 61000-4-2 Level 4 (±15 kV contact) compliance, dynamic resistance of 1.0 Ω, latch-up-free operation in USB 3.0 SuperSpeed lanes, and X3DFN2 package compatibility with high-density PCB layouts.
Technical Context
The ESD8451MUT5G employs a snap-back SCR-based structure optimized for transient suppression without latch-up in USB 3.0, DisplayPort, and other high-speed serial interfaces. Its bidirectional clamping action protects both positive and negative ESD transients while maintaining sub-0.3 pF capacitance to minimize signal distortion.
It operates across −55 °C to +125 °C junction temperature range and delivers 19.0 V clamping at 16 A TLP (IEC 61000-4-2 Level 4 equivalent), with 2.05 V reverse holding voltage and 17 mA holding current ensuring stable off-state behavior during normal operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD8451N2T5G | Lower dynamic resistance (0.84 Ω), lower clamping voltage (9.0 V @ 8 A TLP), XDFN2 package (1.0 × 0.6 mm) | Better suited for space-constrained designs where larger footprint is acceptable and lower clamping is prioritized | Select ESD8451N2T5G when board layout allows 1.0 mm × 0.6 mm footprint and tighter clamping is required for sensitive receivers |
| ESD8006MUT5G | Higher working voltage (5.0 V), higher capacitance (0.55 pF), same X3DFN2 package | Targeted at 5 V logic rails and slower interfaces like HDMI 1.4 (non-TMDS) or PCIe Gen1 | Choose ESD8006MUT5G only if protecting 5 V tolerant lines where 0.55 pF capacitance is acceptable and 3.3 V operation is not required |
Compared with ESD8451N2T5G and ESD8006MUT5G, the ESD8451MUT5G uniquely balances ultra-low 0.30 pF capacitance, 3.3 V working voltage, and compact 0.62 mm × 0.32 mm X3DFN2 footprint-making it optimal for USB 3.0 and MHL 2.0 in space-limited mobile and embedded systems.

FAQ
What is the maximum junction capacitance of ESD8451MUT5G and why does it matter?
The ESD8451MUT5G has a maximum junction capacitance of 0.30 pF at 1 MHz and 0.25 pF at 2.5 GHz. This ultra-low value minimizes signal distortion and insertion loss on high-speed differential lines, enabling reliable operation at USB 3.0 SuperSpeed (5 Gbps) data rates. Exceeding this capacitance would degrade eye diagrams and increase bit error rates in the protected interface.
Is ESD8451MUT5G qualified for automotive applications?
Yes, ESD8451MUT5G is AEC-Q101 qualified and PPAP capable, with the SZ prefix variant (SZESD8451MUT5G) designated for automotive and other applications requiring unique site and control change requirements. Its −55 °C to +125 °C operating range and robust ESD immunity make it suitable for infotainment, telematics, and ADAS interface protection.
Does ESD8451MUT5G support HDMI TMDS lanes?
No, ESD8451MUT5G is not recommended for HDMI 1.4/1.3a TMDS lanes due to latch-up risk under certain load-line conditions. The datasheet explicitly states that ESD8451 should not be used for HDMI applications and recommends ESD8104 or ESD8040 instead. ESD8451MUT5G is validated latch-up free only for USB 2.0/3.0, DisplayPort, and MHL 2.0.
What is the clamping voltage of ESD8451MUT5G under IEC 61000-4-2 Level 4 stress?
Under IEC 61000-4-2 Level 4 (±8 kV contact discharge), the ESD8451MUT5G exhibits a clamping voltage of 19.0 V (TLP equivalent, IPP = 16 A). At the lower 3.7 A pulse (8/20 µs), its clamping voltage is 13.7 V. These values ensure downstream ICs experience limited overvoltage during real-world ESD events.
What package type does ESD8451MUT5G use and what are its dimensions?
ESD8451MUT5G uses the X3DFN2 package (Case 152AF), measuring 0.62 mm × 0.32 mm × 0.24 mm with 0.35 mm pitch. This ultra-compact, leadless, surface-mount package enables high-density routing on mobile and portable PCBs while providing excellent thermal dissipation via the exposed bottom thermal pad.
