Product details
Overview
VBUS05M2-HT5HG3-08 from Vishay Semiconductors is a 2-line, bidirectional and symmetrical (BiSy) ESD protection diode in DFN1110-3A package, rated for ±5.5 V working voltage, <0.45 pF capacitance, <0.05 μA leakage, and ±20 kV IEC 61000-4-2 ESD immunity-designed for high-speed USB2.0/USB3.0 data line protection.
For engineers reviewing the VBUS05M2-HT5HG3-08 datasheet, VBUS05M2-HT5HG3-08 pinout, VBUS05M2-HT5HG3-08 application, or VBUS05M2-HT5HG3-08 equivalent, key selection criteria include low clamping voltage (11–18 V at 1–3.4 A), dynamic resistance of 1 Ω, AEC-Q101 qualification, and DFN1110-3A footprint compatibility with high-density PCB layouts.
Technical Context
The VBUS05M2-HT5HG3-08 implements a three-terminal BiSy architecture with two identical protection paths (Pin 1→3 and Pin 2→3), each featuring a Zener diode for precise breakdown control and dual low-capacitance switching diodes for fast transient clamping. It delivers symmetrical clamping in both polarities without polarity marking.
Its electrical behavior is defined by reverse stand-off voltage (VRWM = 5.5 V), breakdown voltage (VBR = 7.5–9.5 V at 1 mA), and clamping performance validated under IEC 61000-4-5 (8/20 μs, 3.4 A, 60 W peak power) and TLP (100 ns, up to 16 A), enabling robust surge suppression in high-frequency signal lines.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.8 pF typical capacitance, ±12 kV IEC 61000-4-2, SOT-553 package | Requires two devices for dual-line protection; higher capacitance limits use in USB3.0 | Select when cost-sensitive USB2.0-only designs prioritize small size over ultra-low capacitance |
| ESD56081D05 | 2-channel, 0.35 pF typical, ±25 kV ESD rating, DFN1006-3L package (1.0 × 0.6 mm) | Smaller footprint but tighter layout constraints; no AEC-Q101 qualification stated | Prefer for space-constrained consumer electronics where automotive qualification is not required |
Compared with TPD2E001DRYR and ESD56081D05, the VBUS05M2-HT5HG3-08 uniquely balances ultra-low capacitance (≤0.45 pF), AEC-Q101 qualification, and DFN1110-3A mechanical robustness-making it optimal for automotive-grade USB3.0 and HDMI interface protection where signal fidelity and reliability are co-prioritized.

FAQ
What is the maximum clamping voltage of the VBUS05M2-HT5HG3-08 during an ESD event?
The VBUS05M2-HT5HG3-08 clamps to 11–13 V at 1 A and 15–18 V at its peak pulse current of 3.4 A (IEC 61000-4-5 8/20 μs waveform). These values are measured pin-to-ground (Pin 1→3 or Pin 2→3) and ensure downstream ICs remain within safe operating voltage margins during real-world ESD strikes.
Does the VBUS05M2-HT5HG3-08 require polarity-aware PCB layout?
No-the VBUS05M2-HT5HG3-08 features bidirectional and symmetrical (BiSy) clamping, meaning Pin 1 and Pin 2 behave identically in both positive and negative transient conditions. Its schematic symbol shows no anode/cathode distinction between channels, and the device functions correctly regardless of signal polarity on either protected line.
Is the VBUS05M2-HT5HG3-08 qualified for automotive applications?
Yes-the VBUS05M2-HT5HG3-08 is AEC-Q101 qualified, with documented performance across -55 °C to +150 °C junction temperature and human body model (HBM) ESD rating >8 kV. This makes it suitable for deployment in automotive infotainment, telematics, and ADAS subsystems where environmental ruggedness is mandated.
What is the recommended PCB footprint for the VBUS05M2-HT5HG3-08?
Vishay specifies a DFN1110-3A footprint with 1.1 ±0.05 mm × 1.0 ±0.05 mm pad outline, 0.65 mm pin pitch, and thermal pad clearance per document S8-V-3906.04-062. The recommended land pattern includes solder mask defined pads and a non-solder-mask-defined thermal pad centered beneath the package body to enhance heat dissipation during surge events.
How does the VBUS05M2-HT5HG3-08 achieve ultra-low capacitance while maintaining high ESD robustness?
The VBUS05M2-HT5HG3-08 uses a hybrid structure: each channel integrates a precision Zener diode for breakdown control plus two ultra-low-capacitance switching diodes optimized for transient conduction. This architecture separates voltage reference and low-C conduction functions-enabling 0.37 pF typical capacitance while sustaining ±20 kV IEC 61000-4-2 and 60 W IEC 61000-4-5 surge capability.
