Product details
Overview
VMMBZ33C1DD1HG3-08 from Vishay Semiconductors is a single-line bidirectional ESD-protection diode in DFN1006-2B package, designed for high-speed data lines requiring ±28 V reverse standoff voltage, 15 kV IEC 61000-4-2 contact discharge immunity, and low 8 pF typical capacitance at 0 V - deployed in USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the VMMBZ33C1DD1HG3-08 datasheet, VMMBZ33C1DD1HG3-08 pinout, VMMBZ33C1DD1HG3-08 application, or VMMBZ33C1DD1HG3-08 equivalent, key selection criteria include clamping voltage under 59 V at 1.7 A (8/20 μs), dynamic resistance of 3.3 Ω, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device implements a silicon avalanche diode structure optimized for fast transient response to ESD events per IEC 61000-4-2 and IEC 61000-4-5 standards. Its bidirectional configuration enables symmetric clamping across both polarities without external biasing.
The DFN1006-2B footprint supports ultra-compact PCB layouts with <0.5 mm height and MSL level 1 moisture sensitivity. It delivers 100 W peak pulse power (8/20 μs) and maintains stable reverse leakage (<0.001 μA at 28 V, 25 °C) over -55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 28 V - maximum continuous operating voltage before clamping begins; defines safe working range for 24 V nominal systems. |
| ESD Immunity (IEC 61000-4-2) | ±15 kV contact / ±15 kV air discharge - meets Level 4 system-level ESD robustness for automotive and industrial ports. |
| Clamping Voltage | 40–59 V at 1.7 A (8/20 μs) - limits transient voltage seen by downstream ICs during surge events. |
| Capacitance | 6–10 pF at 0 V, 1 MHz - preserves signal integrity on high-speed interfaces like USB 2.0 and LVDS. |
| Dynamic Resistance | 3.3 Ω - determines voltage overshoot during fast transients; lower value improves clamping linearity. |
| Junction Temperature Range | -55 °C to +150 °C - supports operation in under-hood automotive environments and industrial edge nodes. |
| Package | DFN1006-2B (1.0 × 0.6 × 0.4 mm) - enables placement adjacent to connectors with minimal board area impact. |
Pinout & Package

|---|---|---|
| Terminal 1 | Cathode | Connected to protected line; forms anode-cathode pair with Terminal 2 for bidirectional clamping. |
| Terminal 2 | Anode | Reference node (typically GND or common return); completes ESD current path during positive/negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-device solution for ± polarity transients; eliminates need for dual-diode arrays or external bias networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33CA | DO-214AC package; 33 V standoff; unidirectional; 100 W rating; 100 pF capacitance. | Higher capacitance limits use to DC/low-speed lines; larger footprint incompatible with fine-pitch USB/HDMI layouts. | Select when board space allows larger packages and speed requirements are ≤1 Mbps. |
| TPD2E001DRYR | 2-channel, 5.5 V standoff, 12 pF, DRY (SOT-5X3); not AEC-Q101 qualified. | Lower voltage rating restricts use to 3.3 V logic; lacks automotive qualification; higher capacitance impacts >100 Mbps signals. | Prefer for cost-sensitive consumer USB ports where AEC-Q101 is not required. |

FAQ
What is the maximum clamping voltage of the VMMBZ33C1DD1HG3-08 under IEC 61000-4-5 8/20 μs surge conditions?
The VMMBZ33C1DD1HG3-08 exhibits a maximum clamping voltage of 59 V when subjected to a 1.7 A peak pulse current with 8/20 μs waveform per IEC 61000-4-5. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during surge events. The VMMBZ33C1DD1HG3-08 maintains this performance across its full operating temperature range.
Is the VMMBZ33C1DD1HG3-08 qualified for automotive applications?
The VMMBZ33C1DD1HG3-08 is part of the AEC-Q101-qualified VMMBZ family; however, the specific suffix "HG3-08" denotes a RoHS-compliant, green, 10 k/reel tape-and-reel variant - not the AEC-Q101 grade. The AEC-Q101 version carries suffix "H" (e.g., VMMBZ33C1DD1H). Therefore, VMMBZ33C1DD1HG3-08 itself is not AEC-Q101 qualified, though it shares identical die and electrical specs.
What is the capacitance of the VMMBZ33C1DD1HG3-08 at 0 V bias and 1 MHz?
The VMMBZ33C1DD1HG3-08 has a typical capacitance of 8 pF and a maximum of 10 pF at 0 V reverse bias and 1 MHz test frequency. This low capacitance is critical for preserving signal integrity on high-speed interfaces such as USB 2.0 and HDMI, where excessive loading can distort rise/fall times and degrade eye diagrams. The VMMBZ33C1DD1HG3-08 achieves this while maintaining 28 V standoff capability.
Can the VMMBZ33C1DD1HG3-08 be used in bidirectional signal paths without external biasing?
Yes - the VMMBZ33C1DD1HG3-08 is inherently bidirectional due to its symmetrical avalanche diode structure. It provides identical clamping behavior for both positive and negative transients without requiring external DC bias or dual-diode configurations. This makes the VMMBZ33C1DD1HG3-08 ideal for protecting AC-coupled or differential data lines like USB D+/D− or HDMI TMDS pairs.
What is the moisture sensitivity level (MSL) and reflow profile compatibility of the VMMBZ33C1DD1HG3-08?
The VMMBZ33C1DD1HG3-08 is rated MSL level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without dry-pack requirements. It supports standard lead-free reflow profiles with a maximum peak temperature of 260 °C, fully compatible with IPC-7095 guidelines for DFN packages. The VMMBZ33C1DD1HG3-08's UL 94 V-0 molding compound ensures thermal stability during repeated thermal cycling.
