Product details
Overview
VCUT0714BHD1HG3-08 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, 8 pF typical capacitance, and working range of −7 V to +14 V or −14 V to +7 V - deployed in high-speed USB 2.0 and HDMI signal lines.
For engineers reviewing the VCUT0714BHD1HG3-08 datasheet, VCUT0714BHD1HG3-08 pinout, VCUT0714BHD1HG3-08 application, or VCUT0714BHD1HG3-08 equivalent, key selection criteria include asymmetric clamping thresholds, low 8 pF load capacitance, AEC-Q101 qualification status, DFN1006-2A footprint compatibility, and ±25 kV ESD immunity for automotive infotainment interfaces.
Technical Context
The VCUT0714BHD1HG3-08 implements an asymmetrical bidirectional clamping architecture: one path (pin 1→2) clamps at 7 V stand-off and 13 V @ 1 A, while the reverse path (pin 2→1) operates at 14 V stand-off and 27 V @ 1 A - enabling optimized protection for unidirectionally biased data lines like USB D+ or HDMI TMDS pairs. Its DFN1006-2A package delivers <0.1 μA leakage and MSL level 1 solderability.
This device is not a symmetrical TVS; its dual-threshold behavior is intrinsic to its internal diode stack topology, verified by separate VRWM, VBR, and VC values for each polarity direction. It requires no external bias and functions passively between signal line and ground, with minimal parasitic inductance due to ultra-short internal leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±25 kV contact / ±30 kV air per IEC 61000-4-2 - meets automotive and industrial system-level ESD requirements without additional shielding. |
| Clamping Voltage (1→2) | 13 V @ 1 A - protects 3.3 V logic rails from overshoot during fast transients without violating VIH/VIL margins. |
| Clamping Voltage (2→1) | 27 V @ 1 A - safeguards 12 V–15 V auxiliary lines or hot-swap control signals against negative-going spikes. |
| Capacitance | 8 pF @ 0 V, 4 pF @ 7 V - preserves signal integrity on 480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4 channels. |
| Leakage Current | <0.1 μA @ VRWM - avoids DC loading on high-impedance sensor or reference lines. |
| Package | DFN1006-2A (1.0 × 0.6 × 0.3 mm) - enables placement within 1 mm of connector pins for optimal transient suppression. |
| AEC-Q101 Qualified | Yes (per ordering code "H") - validated for automotive powertrain and body electronics applications per stress test conditions. |
Pinout & Package
DFN1006-2A package: 1.0 mm × 0.6 mm × 0.3 mm body, e3 Sn-plated exposed lead frame, MSL level 1, peak reflow ≤260 °C. Pin 1 marked by bar; pin 2 is ground terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Signal Line Anode (for 7 V path) | Connects to protected data line (e.g., USB D+); conducts during negative transients toward ground. |
| Pin 2 | Ground Cathode (common return) | Must be connected directly to low-inductance system ground plane; serves as clamping reference for both polarities. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical Bidirectional Clamping | Enables independent optimization: 7 V/13 V path for low-voltage logic, 14 V/27 V path for higher-bias lines - no external resistor divider needed. |
| Ultra-Low Capacitance | 8 pF typical at 0 V, dropping to 4 pF at 7 V reverse bias - minimizes signal rise-time degradation on high-speed serial links. |
| Low-Leakage Protection | <0.1 μA IR at full VRWM - prevents battery drain in always-on IoT sensor nodes and maintains accuracy in precision analog front-ends. |
| AEC-Q101 Qualification | Validated for temperature cycling, HTRB, and ESD robustness per automotive reliability standards - supports PPAP documentation for Tier-1 suppliers. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|

IC Role / Device Role / Timing Role: Fast-response voltage clamp on CANH/CANL differential pair, exploiting asymmetry to match bus bias (CANH ≈ 3.5 V, CANL ≈ 2.2 V). Use Value: Limits ESD-induced differential skew to <100 mV, preserving bit timing margin at 5 Mbps data rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0AHE3/5BT | Symmetrical 7.0 V VRWM, 12.5 V VC @ 1 A, DO-214AC package (4.5 × 3.3 mm), 100 pF capacitance | Higher capacitance limits use to DC/low-speed lines; larger footprint incompatible with space-constrained USB layouts | Select when board area is unconstrained and only symmetrical clamping is required. |
| TPD2E001DRYR | 2-channel, 5.5 V VRWM, 12 V VC @ 1 A, DFN1006-3 package, 11 pF per channel | Lower stand-off voltage restricts use to 3.3 V-only systems; dual-channel reduces component count but increases layout complexity | Choose for multi-line protection where shared ground and compact dual layout outweigh asymmetry needs. |
Compared with SMAJ7.0AHE3/5BT and TPD2E001DRYR, VCUT0714BHD1HG3-08 uniquely delivers asymmetric clamping in a 1.0 mm × 0.6 mm footprint with sub-8 pF capacitance - making it the only option that simultaneously satisfies automotive HDMI bandwidth, USB 2.0 signal fidelity, and AEC-Q101 compliance in a single device.

FAQ
What is the exact clamping voltage specification for VCUT0714BHD1HG3-08 under 1 A ESD pulse?
The VCUT0714BHD1HG3-08 exhibits two distinct clamping voltages due to its asymmetrical design: 13 V (typical) when current flows from pin 1 to pin 2, and 27 V (typical) when current flows from pin 2 to pin 1. These values are measured per IEC 61000-4-5 8/20 μs waveform and confirmed in the official Vishay datasheet revision 1.5. Both thresholds are guaranteed across −55 °C to +150 °C junction temperature.
Does VCUT0714BHD1HG3-08 meet AEC-Q101 qualification requirements?
Yes, VCUT0714BHD1HG3-08 is AEC-Q101 qualified - indicated by the "H" in its ordering code. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD robustness per JESD22-A114. The device is approved for use in automotive powertrain, body control, and infotainment modules where reliability under thermal and electrical stress is mandatory.
How does the asymmetry of VCUT0714BHD1HG3-08 benefit USB 2.0 interface protection?
The asymmetry of VCUT0714BHD1HG3-08 allows precise matching to USB 2.0 D+ and D− DC bias conditions: the 7 V stand-off path protects the typically 3.3 V referenced D+ line, while the 14 V path accommodates the grounded D− return path. This eliminates over-clamping on one line and under-protection on the other - maintaining differential swing integrity better than symmetrical TVS diodes like SMAJ7.0AHE3/5BT.
What is the maximum allowable PCB trace length between VCUT0714BHD1HG3-08 and the protected connector?
To maintain effective ESD suppression, the PCB trace from VCUT0714BHD1HG3-08 pin 1 to the protected connector should not exceed 3 mm, and the ground connection (pin 2 to ground plane) must be via ≥2 dedicated vias within 1 mm of the pad. Longer traces introduce inductance that degrades clamping response; the DFN1006-2A package's low-inductance design is only fully leveraged with this tight layout.
Can VCUT0714BHD1HG3-08 replace a standard 5 V TVS diode in a 3.3 V logic circuit?
No - VCUT0714BHD1HG3-08 is not a direct replacement for a 5 V symmetrical TVS. Its 7 V stand-off on one path exceeds typical 3.3 V logic VIH max, risking failure to clamp early enough. It is purpose-built for asymmetric bias scenarios (e.g., USB, HDMI). For standard 3.3 V I/O, a 3.3 V-rated symmetrical TVS such as SMF3.3A is appropriate; VCUT0714BHD1HG3-08 requires intentional circuit-level asymmetry to function correctly.
