Product details
Overview
MMBZ27VBQB-QZ from Nexperia is a low-capacitance, bidirectional dual-line ESD protection diode in a DFN1110D-3 (SOT8015) package, designed to protect two signal lines against IEC 61000-4-2/ISO 10605 transients up to 23 kV. It features a 24 V reverse stand-off voltage, 33 V clamping voltage at 2.6 A, and 8 pF capacitance - enabling high-speed interface protection in automotive ECUs and portable electronics.
For engineers reviewing the MMBZ27VBQB-QZ datasheet, MMBZ27VBQB-QZ pinout, MMBZ27VBQB-QZ application, or MMBZ27VBQB-QZ equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flank (SWF) package for automated optical inspection, dual-cathode configuration, and verified clamping performance under 8/20 µs surge and TLP 100 ns pulses.
Technical Context
This device implements a dual-channel, common-cathode bidirectional TVS architecture with independent cathodes (K1, K2) tied to a shared cathode terminal (CC), enabling symmetrical transient suppression on two separate lines referenced to ground. Its low 8 pF capacitance ensures minimal signal integrity impact on USB 2.0, HDMI, or automotive CAN/FlexRay data lines.
The diode operates within an ambient temperature range of −55 °C to +150 °C and supports peak pulse currents up to 2.6 A (8/20 µs) while maintaining clamping below 44 V. Its AEC-Q101 qualification confirms robustness for under-hood automotive environments including engine control units and infotainment interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 24 V - maximum continuous operating voltage before conduction; defines safe signal swing margin for protected lines. |
| Clamping Voltage (VCL) | 33 V (typ) at 2.6 A - limits transient voltage seen by downstream ICs during ESD events, protecting 3.3 V/5 V logic interfaces. |
| ESD Withstand | ±23 kV (IEC 61000-4-2 contact) - exceeds industrial and automotive immunity requirements for human-body-model surges. |
| Diode Capacitance (Cd) | 8 pF (max) at 1 MHz, 0 V - preserves signal rise/fall times in high-speed digital interfaces like USB, MIPI, or LVDS. |
| Package | DFN1110D-3 (SOT8015) - 1.1 mm × 1.0 mm × 0.48 mm leadless package with side-wettable flanks for reliable reflow soldering and AOI compatibility. |
| Junction Temperature (Tj) | 150 °C max - enables operation in high-temperature automotive zones such as powertrain and ADAS modules. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, ultra-thin, leadless plastic package with side-wettable flanks (SWF), optimized for space-constrained PCB layouts and automated optical inspection. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Return path for transient current from Line 1; connects to protected signal line via shortest possible trace. |
| 2 | K2 (Cathode 2) | Return path for transient current from Line 2; electrically isolated from K1 but shares common cathode node internally. |
| 3 | CC (Common Cathode) | Shared cathode connection to system ground; must be routed with low-inductance path to minimize clamping overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line bidirectional protection | Single device protects two independent signal lines (e.g., differential pair or separate I/Os) without polarity constraints. |
| AEC-Q101 qualified | Validated for automotive use per stress-test standard, supporting deployment in engine control, body electronics, and ADAS systems. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated packages, improving manufacturing yield and reliability verification. |
| Low 8 pF capacitance | Maintains signal integrity on high-speed interfaces (e.g., USB 2.0, audio codecs) without degrading eye diagram margins. |
Applications
| Automotive ECU Protection | USB 2.0 Interface Protection |
|---|---|
Use Scenario: Protecting LIN/CAN physical layer inputs and sensor signal lines in engine control units exposed to under-hood ESD and load dump transients. IC Role / Device Role: Bidirectional transient voltage suppressor placed between connector and MCU I/O pins. Use Value: Prevents latch-up or gate oxide damage in automotive microcontrollers by clamping transients to ≤44 V while surviving 23 kV contact discharge. | Use Scenario: Shielding USB 2.0 D+ and D− lines in portable media players and docking stations from user-handling ESD. IC Role / Device Role: Dual-line ESD clamp with matched capacitance to preserve differential signal symmetry and timing skew. Use Value: 8 pF capacitance avoids signal degradation at 480 Mbps; 33 V clamping prevents PHY-level overvoltage during ±8 kV air discharge events. |
| Audio Codec I/O Protection | Industrial Sensor Interface Protection |
Use Scenario: Safeguarding analog audio input/output lines (e.g., headset jack, line-in/out) in smartphones and smart speakers. IC Role / Device Role: Low-leakage (1 nA typ) bidirectional clamp minimizing DC offset and noise injection into sensitive analog paths. Use Value: <1 nA reverse leakage at 24 V ensures no audible hiss or DC bias shift; 23 kV ESD rating covers real-world handling conditions. | Use Scenario: Protecting RS-485 or analog 4–20 mA sensor inputs in factory automation controllers subjected to field wiring ESD and induced surges. IC Role / Device Role: Two-channel transient suppressor with common ground reference, compatible with isolated or non-isolated front-end designs. Use Value: 2.6 A peak pulse rating handles repetitive fast transients; 150 °C junction rating supports operation near industrial power supplies and motor drives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Higher capacitance (12 pF), lower VRWM (5.3 V), same SOT8015 package | Better suited for 3.3 V/5 V low-voltage I/O; not rated for 24 V standby lines | Select when protecting sub-6 V interfaces where tighter clamping (12 V) outweighs higher capacitance penalty. |
| TPD2E001DRYR | Lower clamping (12 V at 1 A), 10 pF, 5 V VRWM, DSBGA package | Smaller footprint (1.0 mm² vs. 1.1 mm²), no SWF; lacks AEC-Q101 qualification | Prefer for space-limited consumer portables where automotive qualification is unnecessary. |
Compared with ESD5V3U2U-2/TR and TPD2E001DRYR, MMBZ27VBQB-QZ uniquely balances 24 V standoff, 8 pF capacitance, AEC-Q101 compliance, and SWF-enabled manufacturability - making it optimal for dual-line automotive and industrial signal protection where voltage margin and process reliability are critical.

FAQ
What is the maximum peak pulse current the MMBZ27VBQB-QZ can handle?
The MMBZ27VBQB-QZ is rated for a maximum peak pulse current (IPPM) of 2.6 A under an 8/20 µs exponential waveform per IEC 61000-4-5. This value is confirmed in both the Quick Reference Data and Limiting Values tables of the official Nexperia datasheet dated 18 July 2024.
Does the MMBZ27VBQB-QZ support bidirectional transient suppression on both protected lines simultaneously?
Yes - the device uses a dual-diode, common-cathode structure (K1/K2 → CC) that provides symmetrical, bidirectional clamping for each line independently. Each channel conducts during positive or negative transients relative to ground, enabling full protection without polarity constraints.
Is the DFN1110D-3 package compatible with standard reflow soldering processes?
Yes - the DFN1110D-3 (SOT8015) package is qualified for lead-free reflow per JEDEC J-STD-020. Nexperia provides recommended stencil thickness (0.1 mm), solder paste volume, and land pattern dimensions in the datasheet's "Soldering" section to ensure reliable joint formation and AOI visibility.
How does the 23 kV ESD rating translate to real-world automotive reliability?
The 23 kV rating per IEC 61000-4-2 (contact discharge) exceeds ISO 10605 requirements for automotive components and reflects validated performance across ten non-repetitive ESD pulses. Combined with AEC-Q101 qualification, this ensures sustained protection in harsh vehicle assembly and service environments.
