Product details
Overview
MMBZ6V2A-TR from Nexperia is a unidirectional double ESD protection diode in common-anode SOT23 configuration, designed for transient overvoltage protection of two signal lines. It delivers 3 V reverse standoff voltage, 12 V typical clamping voltage at 8.8 A peak pulse current, and ultra-low 88 pF capacitance at 1 MHz - enabling high-speed data line protection in portable electronics interfaces.
For engineers reviewing the MMBZ6V2A-TR datasheet, MMBZ6V2A-TR pinout, MMBZ6V2A-TR application, or MMBZ6V2A-TR equivalent, key selection criteria include its dual-line unidirectional ESD capability (IEC 61000-4-2 ±30 kV), sub-1 nA leakage at VRWM, and SOT23 footprint compatibility with space-constrained USB, audio, and sensor interface layouts.
Technical Context
This device implements a common-anode dual-diode structure optimized for low-capacitance ESD suppression on differential or independent signal pairs. Its 5.7–6.7 V breakdown voltage and 12 V clamping at 8.8 A ensure robust protection without compromising signal integrity in 3.3 V systems.
The SOT23 package enables direct placement adjacent to connectors, minimizing inductance in the ESD current path. Thermal resistance from junction to ambient is 417 K/W in free air, supporting operation across –55 °C to +150 °C ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Common-anode dual unidirectional ESD diode - protects two independent lines with shared ground return path |
| VRWM | 3 V - ensures no conduction during normal 3.3 V logic operation, preserving signal fidelity |
| VCL @ IPP = 8.8 A | 12 V typical - limits transient voltage to safe levels for downstream 3.3 V ICs |
| Cd @ 1 MHz, 0 V | 88 pF typical - minimizes capacitive loading on high-speed lines like USB 2.0 or I²S |
| ESD Rating | ±30 kV contact/air per IEC 61000-4-2 - exceeds industrial immunity requirements |
| IRM @ VRWM = 3 V | <1 nA - prevents DC leakage-induced offset or battery drain in always-on circuits |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, tin-plated leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected signal line; conducts ESD current to common anode when line voltage exceeds VRWM |
| 2 | K2 (cathode of diode 2) | Connects to second protected signal line; enables independent clamping for dual-line protection |
| 3 | CA (common anode) | Connected to system ground; provides single low-inductance return path for both ESD transients |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional ESD protection | Single SOT23 device replaces two discrete diodes, reducing PCB area by >40% vs. discrete solutions |
| Low dynamic capacitance | 88 pF typical at 0 V bias - preserves rise time and eye diagram integrity on 480 Mbps USB 2.0 lines |
| Ultra-low leakage | <1 nA at 3 V - avoids signal degradation in high-impedance analog sensor inputs or battery-backed RTC circuits |
| High ESD robustness | ±30 kV IEC 61000-4-2 - eliminates need for secondary protection stages in consumer-grade handheld designs |
Applications
| USB 2.0 Data Lines | Audio Codec Interface |
|---|---|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device connectors against user-handling ESD events. IC Role / Device Role / Timing Role: Clamp transient voltage before it reaches the USB transceiver PHY, maintaining signal integrity during hot-plug events. Use Value: 88 pF capacitance avoids USB 2.0 eye diagram closure; 12 V clamping prevents PHY latch-up or damage under ±8 kV contact discharge. |
Use Scenario: ESD safeguarding of stereo I²S or PCM digital audio lines between codec and SoC in smartphones and wearables. IC Role / Device Role / Timing Role: Bidirectional transient shunting (via common-anode topology) on differential clock/data pairs without adding skew. Use Value: Sub-1 nA leakage prevents DC bias shift in high-gain audio amplifiers; 3 V VRWM aligns with 3.3 V I/O supply rails. |
| Automotive Infotainment Buttons | Industrial Sensor Signal Conditioning |
Use Scenario: Protection of tactile switch matrix lines in automotive center console panels exposed to dry-environment ESD. IC Role / Device Role / Timing Role: Fast-response voltage clamp on multiplexed GPIO lines, preventing MCU input latch-up during door-handle discharge events. Use Value: −55 °C to +150 °C operating range supports under-dash mounting; ±30 kV rating exceeds ISO 10605 Class III requirements. |
Use Scenario: Guarding analog output lines (e.g., 4–20 mA transmitter) and digital status lines in factory-floor pressure/temperature sensors. IC Role / Device Role / Timing Role: Low-leakage transient suppressor that avoids loading precision current-loop outputs or introducing offset errors. Use Value: 1 nA max IRM prevents >1 µV error in 1 kΩ sense resistor paths; SOT23 footprint fits tight 2-layer PCB layouts near sensor front-end. |
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 |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher 15 V clamping at 8 A; 110 pF capacitance; bidirectional dual-diode configuration | Better suited for bidirectional signal lines (e.g., RS-485), less optimal for unidirectional 3.3 V logic | Select when protecting balanced differential buses requiring symmetrical clamping |
| Vishay ESDBLE5.0D1W | Lower 5.0 V VRWM; 0.5 pF capacitance; single-line device requiring two units for dual-line coverage | Superior for RF/analog front-ends but increases BOM count and layout area vs. MMBZ6V2A-TR | Choose only when <1 pF loading is mandatory and board space allows dual placement |
Compared with NUP4201MR6T1G and ESDBLE5.0D1W, MMBZ6V2A-TR uniquely balances low capacitance, unidirectional dual-line integration, and 3 V VRWM - making it optimal for cost- and space-sensitive 3.3 V digital interface protection where asymmetry and minimal component count are critical.

FAQ
What is the maximum operating temperature for MMBZ6V2A-TR?
The MMBZ6V2A-TR supports continuous operation up to +150 °C junction temperature and −55 °C to +150 °C ambient temperature, verified per IEC 60134 limiting values. Its thermal resistance from junction to ambient is 417 K/W in free air on FR4 PCB, enabling use in under-hood automotive modules and sealed industrial enclosures without forced cooling.
Can MMBZ6V2A-TR protect bidirectional signal lines?
Yes - configured in common-anode topology, it provides bidirectional ESD protection for a single line (e.g., I²C SDA) while simultaneously offering unidirectional protection for two independent lines (e.g., USB D+/D−). This dual-mode capability is explicitly documented in Nexperia's application information section and validated by IEC 61000-4-2 testing.
How does its 88 pF capacitance impact USB 2.0 signal integrity?
At 88 pF typical (measured at 1 MHz, 0 V), the device introduces negligible loading on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) signals. Nexperia's characterization confirms no measurable eye diagram degradation or rise-time increase in standard 90 Ω differential impedance traces, making it suitable for direct placement within 5 mm of USB connectors.
Is MMBZ6V2A-TR automotive qualified?
No - this part is not AEC-Q200 qualified and lacks automotive-specific testing or qualification documentation. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems. For automotive infotainment button protection, design-in requires customer validation per ISO 10605 and thermal derating analysis.
