Product details
Overview
MMBZ33VZLS-Q from Nexperia is a low-capacitance bidirectional ESD protection diode in DFN1006BD-2 (SOD882BD) package, designed to protect single high-speed data lines against ±30 kV IEC 61000-4-2 ESD events. It features 27 V reverse stand-off voltage, 36 V clamping at 3 A, 14 pF capacitance, and AEC-Q101 qualification for automotive ECU interfaces.
For engineers reviewing the MMBZ33VZLS-Q datasheet, MMBZ33VZLS-Q pinout, MMBZ33VZLS-Q application, or MMBZ33VZLS-Q equivalent, key selection criteria include bidirectional clamping performance, ultra-low signal-line capacitance, side-wettable flanks for solder inspection, and automotive-grade reliability under 150 °C junction temperature.
Technical Context
This device implements a symmetric dual-cathode Zener structure enabling bidirectional transient suppression across a single line without polarity constraints. Its clamping behavior is characterized by 36 V typical VCL at 3 A (8/20 µs), with dynamic resistance optimized for fast ESD pulse response (tr ≤ 1 ns per IEC 61000-4-2).
Designed for placement directly at I/O connectors, it operates within ±27 V standoff range and maintains <1 nA leakage at VRWM, supporting high-impedance analog and digital signal paths. The 14 pF capacitance at 0 V bias ensures minimal signal integrity impact on USB 2.0, audio, and CAN FD lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 27 V - Maximum continuous working voltage before conduction; defines safe operating margin for 24 V automotive data lines. |
| Clamping Voltage (VCL) | 36 V at 3 A (8/20 µs) - Peak voltage seen by protected IC during surge; limits stress on downstream transceivers. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - Full immunity to worst-case human-body-model ESD events. |
| Diode Capacitance (Cd) | 14 pF at 1 MHz, 0 V - Enables use on 480 Mbps USB 2.0 and 20 MHz audio differential pairs without signal degradation. |
| Junction Temperature (Tj) | 150 °C - Supports operation in engine bay ECUs and under-hood infotainment modules. |
| AEC-Q101 Qualification | Qualified - Meets automotive stress test requirements for discrete semiconductors including HTGB, HTRB, and TCT. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless 2-terminal ultra-small surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for automated optical solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Forms one half of symmetrical bidirectional clamp; connects to protected line in series with K2 to enable dual-polarity conduction. |
| 2 | K2 (Cathode of Diode 2) | Completes bidirectional path; terminal pairing allows clamping for both positive and negative transients relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables protection of AC-coupled or floating signal lines (e.g., USB D+/D−, I²S, LIN) without polarity assumptions. |
| Side-Wettable Flanks (SWF) | Facilitates AOI-compatible reflow inspection on bottom-side terminals-critical for automotive PCB process control. |
| Low 14 pF Capacitance | Preserves signal rise/fall times on >20 MHz interfaces; avoids resonance or attenuation in high-frequency data paths. |
| AEC-Q101 Automotive Qualification | Validated for 15-year service life in automotive environments including thermal cycling, humidity, and mechanical shock. |
Applications
| Automotive ECU Interfaces | USB 2.0 Port Protection |
|---|---|
Use Scenario: Protecting LIN bus or sensor interface lines in body control modules exposed to cable-disconnect transients and assembly-line ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed at connector entry point, clamping ±30 kV ESD pulses within 1 ns. Use Value: Prevents latch-up or gate oxide damage in 3.3 V/5 V microcontroller GPIOs while maintaining <1 nA leakage at 27 V bias. |
Use Scenario: Safeguarding USB 2.0 D+ and D− lines on portable media players against user-handling ESD during hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance shunt protector located within 3 mm of USB receptacle, minimizing inductance in transient return path. Use Value: 14 pF capacitance avoids signal integrity loss at 480 Mbps; 36 V clamping prevents PHY overvoltage beyond ABSMAX. |
| Audio Line Input Protection | Infotainment Display Interface |
Use Scenario: Shielding analog audio inputs (e.g., AUX-in, microphone bias lines) in car stereos from ESD-induced pop/noise and DC offset shifts. IC Role / Device Role / Timing Role: High-impedance parallel clamp that remains non-conductive below 27 V, preserving DC bias and THD+N performance. Use Value: <1 nA IRM at VRWM ensures no audible DC shift or gain error in 100 kΩ input stages; 30 kV rating covers factory handling. |
Use Scenario: Securing MIPI D-PHY clock and data lanes between head unit SoC and TFT display module against board-level ESD coupling. IC Role / Device Role / Timing Role: Ultra-small footprint protector placed adjacent to display flex connector, leveraging DFN1006BD-2's 0.65 mm pitch for dense routing. Use Value: 1.0 mm × 0.6 mm size enables placement directly at connector pads; side-wettable flanks ensure solder joint reliability in vibration-prone dash mounts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC33AT3G | Higher 33 V VRWM, larger SMC package (7.1 mm × 6.2 mm), 100 pF capacitance | Suitable for board-level surge (IEC 61000-4-5), not high-speed signal lines | Select when protecting power rails or low-frequency I/O where capacitance and size are secondary to energy handling. |
| Vishay ESDBLE5.0D1W | Lower 5 V VRWM, same DFN1006 package, 12 pF capacitance, ±20 kV ESD rating | Optimized for 3.3 V/5 V logic and USB-C CC lines, not 24 V automotive data buses | Prefer for consumer electronics with strict 5 V system margins; insufficient standoff for 24 V LIN or CAN FD. |
Compared with SZ1.5SMC33AT3G and ESDBLE5.0D1W, MMBZ33VZLS-Q uniquely balances 27 V standoff, 14 pF capacitance, and AEC-Q101 qualification-making it the only option qualified for high-speed automotive data lines requiring both ESD robustness and signal fidelity.

FAQ
What is the maximum peak pulse current this diode can handle?
The MMBZ33VZLS-Q is rated for 3 A peak pulse current under IEC 61000-4-5 8/20 µs waveform conditions. This value is specified in Table 1 and Table 5 of the datasheet and reflects its capability to safely divert transient energy without failure during standardized surge testing.
Is this device unidirectional or bidirectional, and how is that implemented?
It is a bidirectional ESD protector implemented via a symmetric dual-Zener structure with two cathodes (K1 and K2). As confirmed in Section 5 (Pinning Information) and Figure 3 (V-I characteristics), it clamps equally for positive and negative transients applied between pins 1 and 2, making it ideal for AC-coupled or floating signal lines.
Does the marking '9Z' correspond to the full part number MMBZ33VZLS-Q?
Yes-the marking code '9Z' is the top-side laser marking for MMBZ33VZLS-Q, as documented in Table 4 of the datasheet. This 2-character code is used for traceability and visual identification on the DFN1006BD-2 package body and matches Nexperia's standard marking scheme for this product family.
Can this diode be used in place of a traditional TVS array for USB protection?
No-it protects only one line (single-channel), whereas USB 2.0 requires protection on both D+ and D− lines plus VBUS and GND. MMBZ33VZLS-Q is intended for discrete line protection; multi-line arrays like PUSB3FR4 or ESD56411D have separate channels and shared ground architecture required for full USB port compliance.
