Product details
Overview
VCUT0505B-HD1-GS08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD protection diode in LLP1006-2L package, rated for ±5 V working range, 18 pF typical capacitance at 0 V, <0.1 μA reverse leakage at 5 V, and ±20 kV contact/±25 kV air ESD immunity per IEC 61000-4-2 - deployed on high-speed USB 2.0, HDMI, and audio data lines.
For engineers reviewing the VCUT0505B-HD1-GS08 datasheet, VCUT0505B-HD1-GS08 pinout, VCUT0505B-HD1-GS08 application, or VCUT0505B-HD1-GS08 equivalent, key selection criteria include clamping voltage under 16 V at 3.5 A IPPM, ultra-low 0.4 mm profile, MSL Level 1 solderability, NiPdAu (e4) plating, and verified 1-line protection with no X-ray inspection required.
Technical Context
The VCUT0505B-HD1-GS08 implements a symmetrical avalanche-clamping structure optimized for bidirectional transient suppression between signal and ground. Its low-inductance LLP1006-2L layout enables sub-1 ns response to ESD events while maintaining 7 V minimum breakdown voltage and 12 V clamping at 1 A.
It operates within -40 °C to +125 °C junction temperature range and supports peak pulse power of 56 W (8/20 μs), with capacitance dropping to 14.5 pF at 2.5 V reverse bias - critical for preserving signal integrity in 480 Mbps USB 2.0 channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage Range | ±5 V - defines maximum continuous DC or AC signal swing before conduction begins. |
| Clamping Voltage (IPPM = 3.5 A) | ≤16 V - limits transient overshoot on protected line during worst-case IEC 61000-4-5 surge. |
| Capacitance (VR = 0 V, 1 MHz) | 18 pF typ. - ensures minimal signal distortion on high-speed interfaces like USB 2.0 and HDMI. |
| Leakage Current (VR = 5 V) | ≤0.1 μA - prevents measurable DC loading on sensitive analog or logic inputs. |
| ESD Immunity (IEC 61000-4-2) | ±20 kV contact / ±25 kV air - exceeds industrial and consumer ESD robustness requirements. |
| Package | LLP1006-2L - 1.05 × 0.65 mm, 0.4 mm max height, MSL Level 1, e4 NiPdAu plating. |
| Operating Temperature | -40 °C to +125 °C - supports automotive infotainment and industrial control environments. |
Pinout & Package
LLP1006-2L is a 2-terminal leadless plastic package with exposed pad (no thermal pad connection), 0.4 mm maximum profile, and pin 1 identified by bar marking. Soldering complies with J-STD-020 MSL Level 1 (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (symmetrical) | Bidirectional terminal - connects to signal line; identical electrical behavior in either orientation. |
| Pin 2 | Anode/Cathode (symmetrical) | Ground reference terminal - connects to PCB ground plane; no polarity dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 18 pF at 0 V - preserves rise/fall times in 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4a links. |
| Symmetrical clamping | Identical ±12 V clamping at 1 A - eliminates need for polarity-aware placement on differential or AC-coupled lines. |
| Low-profile packaging | 0.4 mm max height - enables use in space-constrained mobile and wearable PCBs with tight Z-axis clearance. |
| Whisker-free termination | NiPdAu (e4) plating - eliminates tin whisker risk in long-life, high-reliability applications without requiring conformal coating. |
| Visual solder inspection | No X-ray needed - flat, coplanar terminals allow 100% AOI validation of solder joint integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.65 mm × 0.65 mm DRY package; 12 pF capacitance; 10 V clamping at 1 A; ±15 kV contact ESD rating. | Lower capacitance suits >1 Gbps interfaces; lower ESD rating limits use in harsh industrial environments. | Prefer when minimizing capacitive loading is critical and system-level ESD stress is ≤±15 kV. |
| ESD5Z5.0T1G | SOD-523 package (1.2 × 0.8 mm); 25 pF capacitance; 14.5 V clamping at 1 A; ±17 kV contact ESD rating. | Larger footprint and higher capacitance reduce suitability for USB 2.0; better thermal mass for repetitive surges. | Choose where board space allows larger package and higher surge repetition tolerance is prioritized over speed. |
Compared with TPD2E001DRYR and ESD5Z5.0T1G, the VCUT0505B-HD1-GS08 offers the optimal balance of ultra-compact size (1.05 × 0.65 mm), industry-leading ±20 kV contact ESD immunity, and 18 pF capacitance - making it preferred for space-constrained, high-reliability USB and HDMI endpoint protection.

FAQ
What is the maximum clamping voltage of the VCUT0505B-HD1-GS08 under full IEC 61000-4-5 surge conditions?
The VCUT0505B-HD1-GS08 clamps to ≤16 V at its peak pulse current of 3.5 A (8/20 μs waveform per IEC 61000-4-5). This value is measured pin-to-pin and guarantees transient suppression below logic-safe thresholds for 3.3 V and 5 V systems. The VCUT0505B-HD1-GS08 maintains this performance across -40 °C to +125 °C junction temperature.
Does the VCUT0505B-HD1-GS08 require orientation-specific placement on the PCB?
No - the VCUT0505B-HD1-GS08 is a bidirectional symmetrical (BiSy) device with identical electrical characteristics regardless of installation direction. Pin 1 and Pin 2 are functionally interchangeable, enabling simplified layout and eliminating polarity-related assembly errors. This symmetry is confirmed in the VCUT0505B-HD1-GS08 datasheet Figure 4 and Absolute Maximum Ratings table.
Can the VCUT0505B-HD1-GS08 be used in automotive applications?
Yes - the VCUT0505B-HD1-GS08 is qualified for operation from -40 °C to +125 °C junction temperature and meets AEC-Q200 stress test recommendations for passive components. Its ±20 kV contact ESD rating and MSL Level 1 solderability support use in automotive infotainment and body control modules, provided system-level qualification is completed per vehicle OEM requirements.
What is the moisture sensitivity level (MSL) rating for the VCUT0505B-HD1-GS08?
The VCUT0505B-HD1-GS08 carries an MSL Level 1 rating per J-STD-020, meaning it has unlimited floor life and may be stored indefinitely at ≤30 °C/60 % RH without dry-pack requirements. Reflow is supported up to 260 °C peak temperature, compatible with standard lead-free assembly processes - a key advantage documented in the VCUT0505B-HD1-GS08 package data section.
How does the capacitance of the VCUT0505B-HD1-GS08 vary with applied reverse voltage?
The VCUT0505B-HD1-GS08 capacitance decreases from 18 pF at 0 V to 14.5 pF at 2.5 V reverse bias (1 MHz), as shown in Figure 3 of the official datasheet. This voltage-dependent behavior helps maintain signal fidelity on AC-coupled lines like USB D+/D−, where dynamic capacitance reduction minimizes harmonic distortion during high-frequency transitions.
