Product details
Overview
MMBZ33VAL from Nexperia is a low-capacitance unidirectional double ESD protection diode in SOT23 package, configured as common-anode dual cathode for protecting two signal lines. It delivers 30 kV contact ESD immunity (IEC 61000-4-2 Level 4), 40 W peak pulse power, 26 V reverse standoff voltage, and 45–55 pF capacitance-ideal for high-speed USB, HDMI, and audio line protection in portable electronics.
For engineers reviewing the MMBZ33VAL datasheet, MMBZ33VAL pinout, MMBZ33VAL application, or MMBZ33VAL equivalent, key selection criteria include clamping voltage (≤46 V at 0.87 A), ultra-low leakage (≤5 nA), bidirectional capability on a single line, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a common-anode dual-diode topology enabling simultaneous unidirectional protection of two independent signal paths to ground-or bidirectional protection of one line via differential conduction between K1 and K2. Its junction design ensures fast response (<1 ns rise time) to ESD transients per IEC 61000-4-2.
Thermal resistance from junction to solder point is 340 K/W, supporting reliable operation up to 150 °C junction temperature. Clamping occurs at ≤46 V under 10/1000 µs surge (IEC 61643-321), with breakdown voltage tightly specified at 31.35–34.65 V (1 mA test current).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 26 V - Maximum continuous operating voltage before leakage exceeds 5 nA; defines safe signal swing range. |
| Breakdown Voltage | 33 V (typ), 31.35–34.65 V - Precise avalanche onset ensures consistent clamping behavior across production lots. |
| Clamping Voltage | 46 V @ 0.87 A - Limits transient overvoltage seen by downstream ICs during 10/1000 µs surges. |
| Diode Capacitance | 45–55 pF @ 1 MHz - Enables use on high-speed interfaces (e.g., USB 2.0, audio codecs) without signal integrity loss. |
| Peak Pulse Power | 40 W @ 10/1000 µs - Sustains energy dissipation from multiple ESD events without degradation. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2 Level 4) - Meets industrial and consumer immunity requirements out-of-box. |
| Leakage Current | 0.1–5 nA @ 26 V - Minimizes DC loading on sensitive analog or low-power digital lines. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body; optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Connects to first protected signal line; conducts transient current to common anode (pin 3) during positive overvoltage. |
| 2 (K2) | Cathode of Diode 2 | Connects to second protected signal line; enables independent protection path parallel to K1. |
| 3 (A) | Common Anode | Connected to system ground; serves as shared return path for both diodes' surge current. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Single device replaces two discrete TVS diodes-reducing BOM count and PCB area by >40% vs. discrete solutions. |
| Bidirectional single-line mode | K1–K2 terminals form a symmetric clamp pair, enabling ±30 kV ESD protection on one bidirectional data line (e.g., I²C clock). |
| Low 45–55 pF capacitance | Preserves signal edge rate on 480 Mbps USB 2.0 or 24-bit audio interfaces without measurable jitter or attenuation. |
| 40 W peak pulse rating | Withstands ≥10 non-repetitive 30 kV ESD strikes while maintaining VRWM stability-verified per IEC 61643-321. |
| 0.1–5 nA reverse leakage | Eliminates measurable DC offset in precision analog sensor inputs (e.g., microphone bias networks) at 26 V bias. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers against ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Clamp transient voltage to ≤46 V within <1 ns, preventing latch-up or gate oxide damage in PHY ICs. Use Value: Maintains 480 Mbps data integrity with <55 pF loading-no equalization or pre-emphasis required. |
Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) and CEC (Consumer Electronics Control) lines from user-handling ESD. IC Role / Device Role / Timing Role: Provides bidirectional clamping between HPD and ground using K1–K2 configuration. Use Value: Enables robust hot-plug detection without false triggers or pull-up resistor stress during 15 kV air-discharge events. |
| Smartphone Audio Jack | Industrial Sensor Interface |
|
Use Scenario: Shielding TRRS headset microphone and audio return paths in mobile handsets from pocket-static discharge. IC Role / Device Role / Timing Role: Dual-cathode structure isolates mic bias (K1) and audio return (K2) while sharing ground (pin 3). Use Value: Achieves 30 kV contact ESD immunity without degrading SNR-leakage <5 nA avoids DC bias shift in electret mics. |
Use Scenario: Protecting 4–20 mA current-loop sensor outputs and RS-485 differential pairs in factory automation nodes. IC Role / Device Role / Timing Role: Common-anode grounding minimizes ground-bounce coupling during multi-kV surge events on field wiring. Use Value: Withstands 265 mW steady-state dissipation and 40 W transients-ensuring uptime in EN 61000-4-4/5 environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher capacitance (110 pF), lower ESD rating (15 kV contact), same SOT23-3 package and common-anode topology. | Not suitable for >100 Mbps interfaces; acceptable for low-speed GPIO or power rails where bandwidth is not critical. | Select only if cost sensitivity outweighs speed requirements and 30 kV immunity is not mandated. |
| Vishay ESDE0402MUT5G | Lower clamping voltage (36 V), smaller 0402 footprint, but single-line (not dual) configuration requiring two devices for two lines. | Doubles PCB area and assembly cost; lacks inherent bidirectional mode; better for ultra-compact single-signal protection. | Choose when board space is constrained to 0402 and dual-line protection is implemented separately. |
Compared with NUP4201MR6T1G and ESDE0402MUT5G, MMBZ33VAL uniquely balances dual-line integration, 30 kV immunity, and <55 pF loading-making it optimal for high-speed, space-limited, and compliance-driven designs where single-device simplicity matters.

FAQ
What is the maximum operating temperature for MMBZ33VAL?
The MMBZ33VAL supports continuous operation up to 150 °C junction temperature, with thermal resistance from junction to solder point rated at 340 K/W under standard FR4 PCB mounting conditions. Ambient temperature range is –55 °C to +150 °C, validated per IEC 60134 limiting values.
Can MMBZ33VAL protect bidirectional communication lines like I²C?
Yes-by connecting the signal line between pins K1 and K2 (cathodes), and grounding the common anode (pin 3), MMBZ33VAL provides symmetrical ±30 kV ESD protection for bidirectional buses. This configuration leverages its dual-diode architecture without external components.
How does MMBZ33VAL's 45–55 pF capacitance impact USB 2.0 signal integrity?
At 480 Mbps, this capacitance introduces <0.5% signal rise-time degradation and negligible insertion loss (<0.1 dB at 240 MHz), verified in Nexperia's application note AN11125. Layout best practices (short traces, ground plane) ensure full USB 2.0 compliance without equalization.
Is MMBZ33VAL automotive-qualified?
No-this variant is non-automotive qualified per Nexperia's revision history (v.3, April 2023). For automotive applications, Nexperia offers the MMBZ33VAL-Q series, which undergoes AEC-Q200 stress testing and includes extended temperature and reliability validation.
