Product details
Overview
VMMBZ16C1DD1-G3-08 from Vishay Semiconductors is a single-line bidirectional ESD-protection diode in DFN1006-2B package, designed for high-speed data line protection with 14 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 14.5 pF typical capacitance at 1 MHz - deployed in USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the VMMBZ16C1DD1-G3-08 datasheet, VMMBZ16C1DD1-G3-08 pinout, VMMBZ16C1DD1-G3-08 application, or VMMBZ16C1DD1-G3-08 equivalent, key selection criteria include clamping voltage under 8/20 μs surge (23.7 V typ.), dynamic resistance (0.55 Ω), junction temperature range (–55 °C to +150 °C), and AEC-Q101 qualification status.
Technical Context
This device implements a monolithic silicon avalanche diode structure optimized for low-capacitance bidirectional transient suppression. Its symmetrical breakdown behavior (VBR = 16.2–17.3 V at IR = 1 mA) enables robust protection of differential or single-ended signal lines without polarity constraints.
It delivers 108 W peak pulse power per IEC 61000-4-5 (8/20 μs), with clamping voltage tightly controlled at 23.7 V (typ.) during 4 A transients - critical for preserving signal integrity in high-speed interfaces where voltage overshoot must remain below IC absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 14 V - maximum continuous operating voltage before conduction begins; sets upper limit for protected line DC bias. |
| Breakdown Voltage | 16.7 V (typ.) at 1 mA - precise triggering threshold ensuring early clamping before downstream IC damage. |
| Clamping Voltage | 23.7 V (typ.) at 4 A, 8/20 μs - actual voltage seen by protected circuit during worst-case surge event. |
| Capacitance | 14.5 pF at 0 V, 1 MHz - low enough to avoid signal degradation in USB 2.0 (480 Mbps) and HDMI 1.4 applications. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds industrial and automotive ESD immunity requirements. |
| Package | DFN1006-2B (1.0 × 0.6 × 0.4 mm) - ultra-compact footprint enabling placement directly at connector entry points. |
| Operating Temperature | –55 °C to +150 °C - supports under-hood automotive and industrial environments without derating. |
Pinout & Package
DFN1006-2B package: 2-terminal surface-mount device with cathode marking (bar) on terminal 1; no internal die bonding wire - terminals are symmetrical and bidirectional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no fixed polarity required. |
| Terminal 2 | Anode/Cathode (bidirectional) | Complementary terminal forming symmetrical ESD path; both terminals connect to protected line and ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Enables single-device protection of AC-coupled or differential lines (e.g., USB D+/D–) without polarity assignment. |
| Low Capacitance (14.5 pF) | Maintains signal rise/fall time integrity in 480 Mbps USB 2.0 links; avoids eye diagram closure. |
| AEC-Q101 Qualified | Validated for automotive electronics per stress test requirements including HTGB, TCT, and ESD HBM/MM. |
| 0.4 mm Max Height | Allows co-placement with fine-pitch connectors and stacked PCB assemblies without mechanical interference. |
| MSL Level 1 Rating | Enables standard reflow without dry-pack or baking; compatible with high-volume SMT assembly lines. |
Applications
| USB 2.0 Interface Protection | HDMI 1.4 Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D– lines of USB 2.0 ports against ESD events during hot-plug insertion in automotive head units and industrial HMIs. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between connector and USB PHY IC input pins.

IC Role / Device Role / Timing Role: Dual-line ESD clamp (two devices per bus) with shared ground return path. Use Value: –55 °C to +150 °C operation ensures reliability across engine-off cold soak and dashboard solar loading conditions. |
Use Scenario: Protecting CAN-FD physical layer transceiver inputs in factory automation gateways subject to field technician ESD. IC Role / Device Role / Timing Role: Secondary-level ESD guard ahead of primary TVS array, reducing stress on main protection stage. Use Value: 0.55 Ω dynamic resistance enables fast response (<1 ns), limiting transient energy delivered to downstream CAN driver. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14CA | DO-214AC package; 14 V standoff; 33.2 V clamping at 12.3 A; 1000 pF capacitance. | Not suitable for high-speed data lines due to excessive capacitance; limited to power rail or low-frequency I/O. | Select only for non-signal applications where board space and speed are not constraints. |
| TPD2E001DRYR | 2-channel unidirectional; 5 V standoff; 10 pF capacitance; 12 V clamping at 1 A; DRY (X2SON-6) package. | Requires separate devices per polarity; lower clamping but narrower voltage range; not AEC-Q101 qualified. | Prefer for cost-sensitive consumer USB ports where automotive qualification is unnecessary. |
Compared with SMAJ14CA and TPD2E001DRYR, VMMBZ16C1DD1-G3-08 uniquely combines AEC-Q101 qualification, 30 kV ESD immunity, sub-15 pF capacitance, and DFN1006-2B size - making it the only option validated for high-reliability, high-speed automotive data line protection.

FAQ
What is the clamping voltage of VMMBZ16C1DD1-G3-08 under IEC 61000-4-5 surge conditions?
The VMMBZ16C1DD1-G3-08 exhibits a typical clamping voltage of 23.7 V at 4 A peak pulse current with 8/20 μs waveform per IEC 61000-4-5. This value is measured across the device terminals and represents the maximum voltage imposed on the protected line during standardized surge testing - critical for ensuring compatibility with 3.3 V or 5 V logic interfaces.
Is VMMBZ16C1DD1-G3-08 qualified for automotive use?
Yes, VMMBZ16C1DD1-G3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and human-body-model ESD. The qualification applies to the specific DFN1006-2B packaged variant marked "G3-08", confirming suitability for under-hood and cabin electronics in passenger and commercial vehicles.
What is the capacitance of VMMBZ16C1DD1-G3-08 and how does it affect high-speed signals?
VMMBZ16C1DD1-G3-08 has a typical capacitance of 14.5 pF at 0 V and 1 MHz. This low value minimizes signal distortion in high-speed digital interfaces: for example, it introduces <0.5% rise-time degradation in USB 2.0 (480 Mbps) links and preserves HDMI 1.4 eye margin at 2.25 Gbps - verified via TLP and S-parameter modeling in Vishay's application notes.
Does VMMBZ16C1DD1-G3-08 require polarity-aware PCB layout?
No - VMMBZ16C1DD1-G3-08 is a fully bidirectional device with symmetrical electrical characteristics. Its terminals are functionally identical; either can serve as anode or cathode depending on transient polarity. PCB layout requires only a low-inductance path between the protected line and system ground - no orientation-dependent routing or silkscreen polarity marking is needed.
What is the maximum operating temperature for VMMBZ16C1DD1-G3-08?
VMMBZ16C1DD1-G3-08 supports continuous operation from –55 °C to +150 °C junction temperature. This range is validated per AEC-Q101 thermal cycling and high-temperature reverse bias testing, enabling deployment in engine control modules, powertrain sensors, and other under-hood locations where ambient temperatures exceed 125 °C.
