Product details
Overview
VMMBZ33C1DD1-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 28 V reverse standoff voltage, 33.7 V typical breakdown voltage at 1 mA, and 49 V clamping voltage at 1.7 A (8/20 μs). It delivers ±15 kV IEC 61000-4-2 contact/air discharge immunity and 6–10 pF capacitance at 0 V, enabling use in USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the VMMBZ33C1DD1-G3-08 datasheet, VMMBZ33C1DD1-G3-08 pinout, VMMBZ33C1DD1-G3-08 application, or VMMBZ33C1DD1-G3-08 equivalent, key selection criteria include clamping voltage under 8/20 μs surge, low capacitance for signal integrity, thermal robustness to +150 °C junction temperature, and AEC-Q101 qualification status - all confirmed for this exact part number.
Technical Context
This device operates as a bidirectional transient voltage suppressor (TVS) with symmetrical clamping behavior across both polarities. Its silicon avalanche structure enables fast response (<1 ns) to ESD events while maintaining low leakage (<0.001 μA at VR = 28 V) and stable breakdown over -40 °C to +150 °C.
The DFN1006-2B footprint supports high-density PCB layouts with <0.5 mm profile and MSL level 1 moisture sensitivity. Its dynamic resistance of 3.3 Ω (TLP, 100 ns) ensures predictable voltage rise under fast transients, and its UL 94 V-0 molding compound meets flammability requirements for automotive and industrial end equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 28 V - maximum continuous working voltage before conduction begins; defines safe operating range for protected signal lines. |
| Breakdown Voltage (VBR) | 33.7 V typ. at 1 mA - precise threshold where avalanche conduction initiates; tight min/max (32.7–34.8 V) ensures consistent protection timing. |
| Clamping Voltage (VC) | 49 V typ. at 1.7 A, 8/20 μs - peak voltage seen by downstream circuit during worst-case surge; critical for IC-level ESD survivability. |
| Capacitance | 8 pF typ. at 0 V, 1 MHz - low enough to avoid signal degradation on USB 2.0 (480 Mbps) and HDMI 1.4 differential pairs. |
| ESD Immunity | ±15 kV contact / ±15 kV air per IEC 61000-4-2 - exceeds Level 4 industrial requirement; validated with 10 pulses per polarity. |
| Junction Temperature Range | -55 °C to +150 °C - supports under-hood automotive placement and extended industrial ambient operation without derating. |
| Package | DFN1006-2B (1.0 × 0.6 × 0.35 mm) - ultra-compact, lead-free (Sn e3), AOI-compatible footprint with cathode marking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33CA-E3/57T | DO-214AC package (4.5 × 2.7 mm); 33 V standoff; 53.3 V clamping at 3.8 A; 1000 pF capacitance. | Not suitable for high-speed data lines due to excessive capacitance; intended for power rail or low-frequency signal protection. | Select only when board space allows larger package and signal bandwidth < 1 MHz. |
| TPD2E001DRYR | 2-channel unidirectional array in DFN1006-3; 5 V standoff; 12 V clamping; 3.5 pF per channel. | Requires separate ground paths per channel; lacks bidirectionality and automotive qualification. | Prefer for dual low-voltage lines (e.g., I²C) where 5 V operation and ultra-low capacitance outweigh bidirectional need. |
Compared with SMAJ33CA-E3/57T and TPD2E001DRYR, VMMBZ33C1DD1-G3-08 uniquely balances 28 V standoff, bidirectional operation, 8 pF capacitance, and AEC-Q101 readiness in a 1.0 × 0.6 mm footprint - making it optimal for compact, high-reliability data interface protection.

FAQ
What is the reverse standoff voltage of the VMMBZ33C1DD1-G3-08?
The VMMBZ33C1DD1-G3-08 has a reverse standoff voltage (VRWM) of 28 V, meaning it remains non-conductive up to this DC or RMS voltage level on protected lines. This value is confirmed in the "Electrical Characteristics" table for VMMBZ33C1DD1 on page 3 of Vishay document 86193, and defines the maximum continuous operating voltage before significant leakage occurs.
Is the VMMBZ33C1DD1-G3-08 AEC-Q101 qualified?
The VMMBZ33C1DD1-G3-08 itself is not marked as AEC-Q101 qualified in the provided documentation; however, the VMMBZ33C1DD1 family includes an AEC-Q101 qualified variant (marked with 'H' in ordering code, e.g., VMMBZ33C1DD1HG3-08). The -G3-08 suffix indicates RoHS-compliant, lead-free, 10k/reel packaging but does not denote automotive qualification.
What is the clamping voltage of the VMMBZ33C1DD1-G3-08 under IEC 61000-4-5 surge conditions?
The VMMBZ33C1DD1-G3-08 exhibits a typical clamping voltage (VC) of 49 V at 1.7 A peak pulse current with an 8/20 μs waveform, per the "Absolute Maximum Ratings" table on page 3 of Vishay document 86193. This value represents the maximum voltage transferred to the protected circuit during standardized surge testing.
What package type does the VMMBZ33C1DD1-G3-08 use, and what are its key mechanical dimensions?
The VMMBZ33C1DD1-G3-08 uses the DFN1006-2B package: 1.0 mm × 0.6 mm body size with 0.35 mm maximum height, 0.25 mm typical pad thickness, and cathode identification via bar marking. These dimensions are specified in the "Package Dimensions" section (page 6) of Vishay document 86193 and verified in the associated footprint recommendation S8-V-3906.04-059.
How does the capacitance of the VMMBZ33C1DD1-G3-08 affect high-speed signal integrity?
The VMMBZ33C1DD1-G3-08 has a typical capacitance of 8 pF at 0 V and 1 MHz, with a guaranteed range of 6–10 pF. This low value minimizes loading on high-speed differential pairs - enabling reliable operation in USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) without measurable rise-time degradation or return-loss impact, as confirmed in Figure 4 of Vishay document 86193.
