Product details
Overview
VCUT03B1-DD1-G-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD-protection diode in the LLP1006-2M package, rated for ±3.5 V working voltage, 12.5 pF load capacitance, <0.1 μA leakage current, and ±18 kV contact/±20 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 VCUT03B1-DD1-G-08 datasheet, VCUT03B1-DD1-G-08 pinout, VCUT03B1-DD1-G-08 application, or VCUT03B1-DD1-G-08 equivalent, key selection criteria include clamping voltage at 3.5 A (≤11.5 V), ultra-low package height (<0.4 mm), MSL level 1 solderability, and BiSy symmetry enabling single-device protection of bidirectional signal paths without polarity concerns.
Technical Context
The VCUT03B1-DD1-G-08 implements a symmetrical Zener-based clamping structure with matched forward/reverse breakdown characteristics (VBR = 5.8–7.5 V), enabling identical positive/negative transient suppression. Its low-inductance LLP1006-2M layout minimizes overshoot during sub-nanosecond ESD events.
It operates within –40 °C to +125 °C junction temperature range and supports peak pulse power of 40 W (8/20 μs, IEC 61000-4-5). Clamping voltage rises predictably with current: 7.8–9.0 V at 1 A, 9.5–11.5 V at 3.5 A - critical for preserving signal integrity in 3.3 V logic interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±3.5 V - defines maximum continuous signal swing before conduction; compatible with 3.3 V I/O rails. |
| Clamping Voltage @ 3.5 A | ≤11.5 V - limits transient overvoltage seen by downstream ICs during worst-case IEC 61000-4-5 surge. |
| Load Capacitance | 12.5 pF @ 0 V - ensures minimal signal distortion on USB 2.0 (480 Mbps) and audio differential pairs. |
| ESD Immunity | ±18 kV contact / ±20 kV air - exceeds IEC 61000-4-2 Level 4 for robust system-level ESD compliance. |
| Leakage Current | <0.1 μA @ 3.5 V - prevents DC loading on high-impedance sensor or reference lines. |
| Package Height | <0.4 mm - enables use in ultra-thin mobile devices and stacked PCB assemblies. |
| Moisture Sensitivity | MSL level 1 - allows unlimited floor life and standard reflow without baking. |
Pinout & Package
VCUT03B1-DD1-G-08 is housed in the LLP1006-2M surface-mount package (1.05 mm × 0.65 mm × <0.4 mm), featuring two terminals with pin 1 marked by a bar. The package uses NiPdAu (e4) plating to prevent whisker growth and supports vision-based solder inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (symmetrical) | BiSy terminal - interchangeable with Pin 2; connects to protected signal line. |
| Pin 2 | Anode/Cathode (symmetrical) | BiSy terminal - interchangeable with Pin 1; connects to system ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetry (BiSy) | Identical clamping behavior for ± transients - eliminates polarity marking and routing constraints. |
| Ultra-Low Capacitance | 12.5 pF typical - preserves signal rise/fall times on >100 MHz data lines without added jitter. |
| Low-Inductance Layout | Short internal leads in LLP1006-2M - reduces voltage overshoot during <1 ns ESD rise time events. |
| No X-ray Inspection Required | Visible solder joint geometry - enables automated optical inspection (AOI) for high-volume manufacturing traceability. |
| Pb-Free & RoHS Compliant | NiPdAu (e4) termination - meets JEDEC J-STD-609 and avoids tin whisker risk in long-life applications. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Signal-line ESD clamp placed directly at connector, shunting transients to ground before reaching PHY. Use Value: 12.5 pF capacitance avoids degrading 480 Mbps eye diagram; ±18 kV rating ensures pass/fail compliance in system-level IEC 61000-4-2 testing. | Use Scenario: Safeguarding TMDS clock and data channels in portable HDMI sources (e.g., tablets, dongles) exposed to user-touch ESD. IC Role / Device Role / Timing Role: Low-capacitance bidirectional protector between source driver and HDMI connector. Use Value: Symmetrical clamping maintains differential signal balance; <0.4 mm height fits tight space behind micro-HDMI connectors. |
| Smartphone Audio Jacks | Industrial Sensor Interfaces |
Use Scenario: ESD protection for analog audio paths (MIC, HP_L/R) in smartphones where jack insertion generates ±8 kV discharges. IC Role / Device Role / Timing Role: Ground-referenced clamp on unidirectional analog signal lines with DC bias. Use Value: <0.1 μA leakage prevents DC offset shift in amplifier input stages; ±3.5 V working range accommodates typical audio signal swings. | Use Scenario: Protecting RS-485 or CAN FD transceiver I/O pins in factory automation nodes subject to cable-discharge events. IC Role / Device Role / Timing Role: Secondary-level ESD suppressor mounted at field-wire entry point, upstream of transceiver. Use Value: 40 W peak pulse power handles multi-shot surges; MSL level 1 supports reflow after conformal coating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A-E3/57T | Unidirectional, DO-214AC package (4.5 mm × 3.9 mm), 150 pF capacitance, 100 W peak power | Requires polarity-aware layout; unsuitable for high-speed data due to high capacitance | Select only for low-frequency power/signal lines where size and speed are not constraints. |
| TPD2E001DRYR | Two-channel, SOT-553 package, 11 pF per line, ±12 kV contact ESD rating, integrated 5 V VCC clamp | Offers dual-line protection in same footprint; lower ESD rating but includes supply-rail protection | Prefer when protecting both signal and VCC on compact interfaces like I²C or GPIO banks. |
Compared with SMAJ3.3A-E3/57T and TPD2E001DRYR, VCUT03B1-DD1-G-08 delivers superior high-speed interface compatibility via its 12.5 pF capacitance and BiSy symmetry, while occupying <5% of the board area of the SMAJ device - making it optimal for space-constrained, multi-gigabit-per-second signal paths.

FAQ
What is the maximum operating temperature range for VCUT03B1-DD1-G-08?
The VCUT03B1-DD1-G-08 has a specified junction temperature range of –40 °C to +125 °C and storage temperature range of –55 °C to +150 °C. This wide thermal envelope supports deployment in automotive cabin modules, industrial PLCs, and outdoor consumer devices where ambient conditions exceed standard commercial limits. The LLP1006-2M package's low thermal resistance enables reliable operation at full rated power across this range.
Does VCUT03B1-DD1-G-08 require orientation-specific placement on the PCB?
No - VCUT03B1-DD1-G-08 is a bidirectional symmetrical (BiSy) device with identical electrical behavior in either direction, so Pin 1 and Pin 2 are functionally interchangeable. The bar marking indicates Pin 1 solely for traceability and assembly verification; swapping terminals does not affect ESD performance or signal integrity. This simplifies layout and eliminates polarity-related assembly errors.
What is the clamping voltage of VCUT03B1-DD1-G-08 at 1 A and 3.5 A peak pulse current?
The VCUT03B1-DD1-G-08 exhibits a typical clamping voltage of 7.8–9.0 V at 1 A and 9.5–11.5 V at 3.5 A (IEC 61000-4-5, 8/20 μs waveform). These values are measured across the device under standardized surge conditions and define the maximum overvoltage imposed on protected circuitry - critical for ensuring downstream 3.3 V logic ICs remain within absolute maximum ratings during transient events.
Can VCUT03B1-DD1-G-08 be used for protecting 5 V logic interfaces?
No - VCUT03B1-DD1-G-08 has a reverse stand-off voltage (VRWM) of 3.5 V, meaning it begins conducting significantly above that threshold. Using it on a 5 V rail would cause excessive leakage and potential malfunction. For 5 V interfaces, Vishay offers variants such as VCUT05B1-DD1 (VRWM = 5.0 V); always match the stand-off voltage to the system's steady-state signal voltage.
Is VCUT03B1-DD1-G-08 compliant with lead-free soldering standards?
Yes - VCUT03B1-DD1-G-08 features NiPdAu (e4) terminal plating and is qualified for peak reflow temperatures up to 260 °C per J-STD-020. It carries MSL level 1 rating, permitting unlimited exposure to ambient conditions prior to soldering. The device is RoHS-compliant and fully compatible with standard Pb-free reflow profiles used in modern electronics assembly.
