Product details
Overview
VBUS05M2-HT5-G3-08 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 contact/air discharge immunity - deployed in high-speed USB2.0/USB3.0 data line protection.
For engineers reviewing the VBUS05M2-HT5-G3-08 datasheet, VBUS05M2-HT5-G3-08 pinout, VBUS05M2-HT5-G3-08 application, or VBUS05M2-HT5-G3-08 equivalent, key selection criteria include low clamping voltage (11–18 V at 1–3.4 A), dynamic resistance ≤1 Ω, AEC-Q101 qualification, and DFN1110-3A footprint compatibility with high-density PCB layouts.
Technical Context
The VBUS05M2-HT5-G3-08 implements a three-terminal BiSy architecture with two identical protection paths (Pin 1→Pin 3 and Pin 2→Pin 3), each featuring a Zener diode for precise breakdown control and dual low-capacitance switching diodes for fast transient response. Its symmetrical clamping ensures equal positive/negative transient suppression without polarity dependency.
Designed for signal integrity-critical interfaces, it delivers <0.45 pF load capacitance at 0–3.3 V bias and maintains stable clamping performance up to 150 °C junction temperature, supporting automotive-grade reliability per AEC-Q101 with MSL Level 1 soldering compatibility (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Lines | 2 independent bidirectional channels (Pin 1 & Pin 2 to Pin 3) |
| Working Voltage | ±5.5 V max reverse stand-off - supports USB2.0/3.0 and HDMI DC bias rails |
| Clamping Voltage | 11–13 V at 1 A IPP; 15–18 V at 3.4 A IPP - limits downstream IC stress during ESD events |
| Capacitance | 0.37–0.45 pF at 1 MHz and 0/3.3 V - preserves signal integrity up to 5 Gbps |
| ESD Rating | ±20 kV contact & air discharge (IEC 61000-4-2) - exceeds industrial and automotive immunity requirements |
| Leakage Current | <0.001 μA typical at 5.5 V - avoids signal distortion or power loss in always-on lines |
| Dynamic Resistance | ≤1 Ω (TLP, 100 ns) - enables rapid energy diversion with minimal voltage overshoot |
Pinout & Package
VBUS05M2-HT5-G3-08 is housed in a 3-pin DFN1110-3A package (1.1 × 1.0 × 0.4 mm), with exposed thermal pad (non-electrical), e3 tin-plated terminations, and AOI-compatible marking. Pin 1 and Pin 2 serve as protected I/O terminals; Pin 3 is common cathode/anode ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Protected Data Line 1 Input/Output | Bidirectional ESD path to Pin 3; connects to USB D+ or HDMI TMDS+ |
| Pin 2 | Protected Data Line 2 Input/Output | Bidirectional ESD path to Pin 3; connects to USB D− or HDMI TMDS− |
| Pin 3 | Common Ground Reference | Shared cathode/anode node for both protection paths; must connect to low-impedance system ground |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional & Symmetrical (BiSy) Clamping | Equal ±7.5–9.5 V breakdown and ±11–18 V clamping across both polarities - eliminates need for polarity-aware layout |

IC Role / Device Role / Timing Role: Compact 2-channel solution minimizing board area while maintaining independent clamping for each high-speed differential pair. Use Value: DFN1110-3A footprint allows placement adjacent to USB-C receptacle; low leakage avoids phantom charging issues in standby mode. |
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, 0.5 pF typical capacitance, ±12 kV IEC 61000-4-2, no AEC-Q101 rating | Requires two devices for dual-line protection; not qualified for automotive environments | Select when cost-sensitive consumer designs prioritize footprint over automotive qualification and ultra-low capacitance |
| SZ1.8SMAT5G | Unidirectional, 1.8 V standoff, 12 pF capacitance, ±30 kV ESD rating, TO-236 package | Not suitable for high-speed data lines due to high capacitance; requires polarity-aware routing | Choose only for low-frequency power rail or GPIO protection where speed and symmetry are irrelevant |
Compared with TPD2E001DRYR and SZ1.8SMAT5G, the VBUS05M2-HT5-G3-08 uniquely combines dual-channel symmetry, sub-0.45 pF capacitance, AEC-Q101 qualification, and DFN1110-3A packaging - making it the only option that satisfies simultaneous requirements for USB3.0 signal integrity, automotive reliability, and space-constrained layouts.

FAQ
What is the maximum operating temperature range for the VBUS05M2-HT5-G3-08?
The VBUS05M2-HT5-G3-08 supports a junction temperature range of −55 °C to +150 °C, fully compliant with AEC-Q101 requirements for automotive under-hood and infotainment applications. This extended range ensures reliable operation in harsh thermal environments without derating, and its MSL Level 1 rating permits standard reflow soldering without pre-baking.
Does the VBUS05M2-HT5-G3-08 require external biasing or control signals?
No, the VBUS05M2-HT5-G3-08 is a passive, unidirectional/bidirectional Zener-based ESD clamp with no external bias or enable pins. It operates automatically across its ±5.5 V working range, drawing less than 0.001 μA leakage at rated voltage. The device relies solely on its internal BiSy structure - Pin 1 and Pin 2 clamp symmetrically to Pin 3 ground without any active circuitry or configuration.
How does the VBUS05M2-HT5-G3-08 achieve 0.37 pF capacitance while maintaining ±20 kV ESD immunity?
The VBUS05M2-HT5-G3-08 achieves ultra-low capacitance through a hybrid structure: each protection path integrates a precision Zener diode for controlled breakdown voltage (7.5–9.5 V) and two low-capacitance switching diodes optimized for minimal junction area. This architecture separates clamping function from capacitance generation, enabling <0.45 pF at 1 MHz while sustaining ±20 kV IEC 61000-4-2 immunity via robust silicon design and optimized doping profiles.
Can the VBUS05M2-HT5-G3-08 be used to protect a single-ended signal like a UART line?
Yes, the VBUS05M2-HT5-G3-08 can protect a single-ended signal by using one channel (e.g., Pin 1 to Pin 3) while leaving Pin 2 unconnected or grounded, though this underutilizes its dual-channel capability. Its ±5.5 V working range suits 3.3 V or 5 V UART rails, and its <0.05 μA leakage avoids loading. However, for dedicated single-ended protection, smaller-footprint single-channel alternatives may offer better cost-per-channel efficiency.
Is the thermal pad on the VBUS05M2-HT5-G3-08 electrically connected or isolated?
The exposed thermal pad on the VBUS05M2-HT5-G3-08 is electrically isolated from all internal circuitry and serves only for mechanical attachment and thermal conduction. Vishay's package documentation specifies no electrical connection between the pad and any pin; it may be left floating or tied to ground for improved thermal performance, but grounding does not affect ESD clamping behavior or electrical characteristics of the VBUS05M2-HT5-G3-08.
