Product details
Overview
VCUT0714BHD1-G3-08 from Vishay Semiconductors is a bidirectional asymmetrical (BiAs) single-line ESD protection diode in DFN1006-2A package, rated for ±25 kV contact / ±30 kV air discharge per IEC 61000-4-2, with clamping voltages of 13 V (pin 1→2) and 27 V (pin 2→1) at 1 A, and typical capacitance of 8 pF at 0 V - deployed in high-speed USB 2.0 and automotive infotainment data lines.
For engineers reviewing the VCUT0714BHD1-G3-08 datasheet, VCUT0714BHD1-G3-08 pinout, VCUT0714BHD1-G3-08 application, or VCUT0714BHD1-G3-08 equivalent, key selection criteria include asymmetrical clamping thresholds (7 V / 14 V stand-off), ultra-low leakage (<0.1 μA), MSL Level 1 solderability, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The VCUT0714BHD1-G3-08 implements an asymmetrical bidirectional clamping architecture: one direction (pin 1 to pin 2) provides low-voltage protection with VRWM = 7 V and VC = 13 V @ 1 A, while the reverse direction (pin 2 to pin 1) supports higher-voltage operation with VRWM = 14 V and VC = 27 V @ 1 A. This enables optimized protection for unidirectional signal paths with ground-referenced transients.
Its DFN1006-2A package delivers minimal parasitic inductance and 8 pF typical capacitance at 0 V, ensuring signal integrity on 480 Mbps USB 2.0 lines. The device operates across -55 °C to +150 °C junction temperature and meets AEC-Q101 stress testing requirements for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±25 kV contact / ±30 kV air per IEC 61000-4-2 - ensures robust immunity against human-body-model ESD events in handheld and automotive interfaces. |
| Clamping Voltage (1→2) | 13 V @ 1 A - limits transient overvoltage on low-voltage signal lines (e.g., USB D+), preventing damage to 3.3 V or 5 V transceivers. |
| Clamping Voltage (2→1) | 27 V @ 1 A - protects higher-voltage rails or bidirectional buses where peak transients exceed 14 V. |
| Capacitance | 8 pF @ 0 V, 4 pF @ 7 V - maintains <0.1 dB insertion loss up to 250 MHz, suitable for USB 2.0 full-speed signaling. |
| Leakage Current | <0.1 μA @ VRWM - avoids DC loading on high-impedance sensor or analog front-end inputs. |
| Package | DFN1006-2A (1.0 × 0.6 × 0.4 mm) - enables placement adjacent to connectors without board area penalty; MSL Level 1 allows standard reflow. |
Pinout & Package
VCUT0714BHD1-G3-08 uses the DFN1006-2A surface-mount package: 1.0 mm × 0.6 mm body, 0.4 mm max height, e3 tin-plated exposed side walls for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode for 7 V path / Cathode for 14 V path | Connects to protected signal line requiring lower clamping (e.g., USB D+); defines asymmetry polarity. |
| Pin 2 | Cathode for 7 V path / Anode for 14 V path | Connects to system ground; forms dual-path clamping network with Pin 1 for BiAs operation. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical Bidirectional Clamping | Enables independent optimization of positive and negative transient suppression - e.g., 7 V working range toward signal, 14 V toward supply rail. |
| Low Capacitance (8 pF) | Preserves signal edge rate and eye diagram integrity on 480 Mbps USB 2.0 differential pairs without equalization. |
| AEC-Q101 Qualified Variant Available | Validated for automotive powertrain and infotainment systems requiring extended temperature (-55 °C to +150 °C) and mechanical stress compliance. |
| e3 Tin Plating | Enables automated optical inspection (AOI) of solder joints without X-ray; eliminates lead-free solder wetting concerns. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 host/device ports against ESD during cable insertion or handling.

Use Value: Enables AEC-Q101-compliant design without adding series resistance or degrading 1.5 Gbps video timing budgets. |
| Industrial HMI Touch Interfaces | Medical Patient Monitor Sensors |
Use Scenario: Guarding I²C or SPI communication lines between touch controller and MCU in factory-floor HMIs exposed to operator ESD. IC Role / Device Role / Timing Role: Low-leakage (<0.1 μA) protector on bidirectional control bus, using asymmetry to accommodate varying pull-up voltages. Use Value: Eliminates false touch interrupts caused by transient-induced logic glitches while preserving bus rise time. | Use Scenario: Safeguarding analog front-end inputs of ECG or SpO₂ sensor modules connected via flexible PCB traces. IC Role / Device Role / Timing Role: Ground-referenced ESD clamp on low-noise amplifier inputs, minimizing added capacitance to preserve SNR. Use Value: Maintains sub-μV input-referred noise floor and prevents saturation during 15 kV ESD events per IEC 61000-4-2. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Unidirectional, 7.0 V VRWM, SMA package (4.5 × 2.7 mm), 100 pF capacitance | Requires external biasing for bidirectional use; unsuitable for high-speed data lines due to high capacitance | Select only for low-frequency power rail protection where size and speed are not constraints. |
| TPD2E001DRYR | Bi-directional symmetric, 5.5 V VRWM, 12 pF capacitance, DRY (SOT-5X3) package | Lacks asymmetry; clamps equally at ±5.5 V - insufficient for 14 V tolerant signal paths | Prefer for symmetric 3.3 V I/O protection; avoid when one side requires higher stand-off voltage. |
Compared with SMAJ7.0A and TPD2E001DRYR, VCUT0714BHD1-G3-08 uniquely delivers asymmetrical clamping (7 V / 14 V), 8 pF capacitance, and DFN1006-2A footprint - enabling compact, high-fidelity protection for mixed-voltage data interfaces without redesigning layout or compromising signal integrity.

FAQ
What is the clamping voltage behavior of VCUT0714BHD1-G3-08 under ESD stress?
The VCUT0714BHD1-G3-08 exhibits asymmetrical clamping: from pin 1 to pin 2, it clamps at 13 V @ 1 A and 15 V @ 3.6 A; from pin 2 to pin 1, it clamps at 27 V @ 1 A and 30 V @ 2 A. This dual-threshold behavior is intrinsic to its BiAs structure and is verified per IEC 61000-4-5 8/20 μs waveform testing. VCUT0714BHD1-G3-08 achieves this without external biasing or additional components.
Does VCUT0714BHD1-G3-08 meet automotive qualification standards?
VCUT0714BHD1-G3-08 itself is not AEC-Q101 qualified; however, the base part VCUT0714BHD1 is offered in an AEC-Q101 qualified variant (e.g., VCUT0714BHD1HG3-08). The -G3-08 suffix denotes RoHS-compliant, lead-free, green packaging with 10k/reel tape-and-reel - confirming that VCUT0714BHD1-G3-08 shares identical die and electrical specs with the qualified version, differing only in environmental coding.
How does the capacitance of VCUT0714BHD1-G3-08 vary with applied voltage?
VCUT0714BHD1-G3-08 capacitance decreases with increasing reverse bias: 8 pF at 0 V, 6.4 pF at 3.5 V (pin 1→2), 4 pF at 7 V (pin 1→2), and 4 pF at 7 V (pin 2→1). This voltage-dependent reduction minimizes signal distortion on biased data lines. All values are measured at 1 MHz and confirmed in the official Vishay datasheet for VCUT0714BHD1-G3-08.
Can VCUT0714BHD1-G3-08 replace a standard bidirectional TVS in USB applications?
Yes - but only when asymmetry is required. VCUT0714BHD1-G3-08 replaces symmetric TVS diodes in designs where one side of the signal path operates near 7 V and the other near 14 V (e.g., USB VBUS-coupled data lines). Its 8 pF capacitance and 13 V clamping on the low-side path make VCUT0714BHD1-G3-08 superior to generic 15–20 pF bidirectional TVS devices for USB 2.0 compliance.
What is the maximum peak pulse current rating for VCUT0714BHD1-G3-08?
VCUT0714BHD1-G3-08 supports 3.6 A peak pulse current (IPPM) from pin 1 to pin 2, and 2 A from pin 2 to pin 1, per IEC 61000-4-5 8/20 μs waveform. These values correspond to 61 W and 50 W peak pulse power respectively. Derating is not required below +125 °C ambient, as the device's thermal resistance and silicon design sustain these ratings within its -55 °C to +150 °C operating range.
