Product details
Overview
VCUT05B1-DD1-G-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD protection diode in the LLP1006-2M package, rated for ±5.5 V working voltage, 10 pF typical capacitance at 0 V, <0.1 μA leakage at 5.5 V, and ±30 kV IEC 61000-4-2 contact/air discharge immunity. It serves as a low-inductance transient voltage suppressor on high-speed data lines such as USB 2.0 or HDMI interfaces.
For engineers reviewing the VCUT05B1-DD1-G-08 datasheet, VCUT05B1-DD1-G-08 pinout, VCUT05B1-DD1-G-08 application, or VCUT05B1-DD1-G-08 equivalent, key selection criteria include clamping voltage at 1 A (8.3–10.5 V), reverse breakdown (6–8.5 V), low-profile packaging (<0.4 mm height), MSL level 1 soldering compatibility, and BiSy operation for AC-coupled signal paths.
Technical Context
The VCUT05B1-DD1-G-08 employs a symmetrical silicon avalanche structure enabling identical clamping behavior for positive and negative transients without polarity dependence. Its ultra-low parasitic inductance stems from the LLP1006-2M's short internal leads and compact 1.05 mm × 0.65 mm footprint.
It operates within a junction temperature range of –55 °C to +145 °C and delivers 38 W peak pulse power (8/20 μs, IEC 61000-4-5) with a maximum clamping voltage of 12.5 V at 3 A peak current. The device exhibits 8 pF capacitance at 2.5 V bias-critical for preserving signal integrity in 480 Mbps USB 2.0 channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers against ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 10 pF capacitance preserves 480 Mbps eye opening; ±30 kV rating prevents latch-up or damage to PHY ICs. | Use Scenario: Safeguarding the HPD (Hot-Plug Detect) line in HDMI source/sink devices from user-handling ESD. IC Role / Device Role / Timing Role: Low-leakage (≤0.1 μA) clamp that avoids false HPD toggling during normal operation. Use Value: ≤5.5 V stand-off ensures compatibility with 3.3 V or 5 V HPD logic levels while clamping transients below 12.5 V. |
| Smartphone Audio Jacks | Industrial Sensor Interfaces |
Use Scenario: ESD protection for analog audio paths (MIC, EAR, GND) exposed via 3.5 mm TRRS jacks. IC Role / Device Role / Timing Role: Symmetrical clamp preventing DC offset shift or pop-noise during transient events. Use Value: BiSy operation avoids polarity-sensitive routing; 8 pF at 2.5 V minimizes high-frequency attenuation in 20 kHz bandwidth. | Use Scenario: Shielding RS-485 or CAN FD data lines in factory automation nodes from electrostatic discharge in dusty environments. IC Role / Device Role / Timing Role: Standoff-compatible protector for ±5 V differential signaling with minimal added capacitance. Use Value: 38 W peak power rating handles repetitive surges; –55 °C to +145 °C operating range supports extended industrial thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.75 pF lower typical capacitance (9.25 pF), but higher clamping voltage (13.5 V at 1 A); same LLP1006-2M package | Better for >1 Gbps interfaces; less suitable where sub-10 V clamping is critical for 3.3 V I/O tolerance | Select TPD2E001DRYR when minimizing capacitive loading outweighs clamping voltage margin |
| ESD5Z5.0T1G | Higher leakage (0.5 μA max), larger SOD-523 package (1.3 mm × 0.85 mm), 12 pF capacitance | Less space-constrained designs; not recommended for ultra-thin mobile PCBs or high-density USB layouts | Choose ESD5Z5.0T1G only if LLP1006-2M placement is mechanically infeasible |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, VCUT05B1-DD1-G-08 delivers the optimal balance of low clamping voltage (≤10.5 V at 1 A), industry-leading 10 pF capacitance, and ultra-thin 0.4 mm profile-making it preferred for space- and signal-integrity–constrained USB 2.0 and HDMI implementations.

FAQ
What is the maximum clamping voltage of VCUT05B1-DD1-G-08 at 3 A peak current?
The VCUT05B1-DD1-G-08 has a maximum clamping voltage of 12.5 V at 3 A peak pulse current (8/20 μs waveform, per IEC 61000-4-5). This value is specified in the Electrical Characteristics table and confirmed in Figure 5 of the official Vishay datasheet (Doc. #81149, Rev. 2.0). Maintaining clamping below 12.5 V protects 3.3 V and 5 V I/O structures from overstress during severe transients.
Does VCUT05B1-DD1-G-08 require orientation-specific placement on the PCB?
No, VCUT05B1-DD1-G-08 does not require orientation-specific placement. As a bidirectional symmetrical (BiSy) device, its terminals are functionally identical-either pin may connect to the signal line and the other to ground. The bar marking indicates Pin 1 solely for traceability and visual alignment; electrical performance is identical regardless of mounting direction.
What is the moisture sensitivity level (MSL) rating for VCUT05B1-DD1-G-08?
The VCUT05B1-DD1-G-08 carries an MSL level 1 rating per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This is enabled by its LLP1006-2M package construction and moisture-resistant molding compound (UL 94 V-0), simplifying manufacturing logistics for high-throughput SMT lines.
Can VCUT05B1-DD1-G-08 be used on 5 V logic lines?
Yes, VCUT05B1-DD1-G-08 is rated for a maximum reverse stand-off voltage of 5.5 V, making it fully compatible with 5 V logic systems. Its reverse breakdown starts at 6 V (min), ensuring no conduction during normal operation, while clamping transients well below destructive thresholds-validated by ±30 kV IEC 61000-4-2 testing.
What is the typical capacitance of VCUT05B1-DD1-G-08 at 2.5 V reverse bias?
The typical capacitance of VCUT05B1-DD1-G-08 at 2.5 V reverse bias and 1 MHz is 8 pF, as specified in the Electrical Characteristics table (Document #81149, page 2). This lower-bias capacitance is especially relevant for AC-coupled data lines, where reduced loading improves high-frequency signal fidelity beyond what the 0 V value alone indicates.
