Product details
Overview
MMBZ27VCL from Nexperia is a unidirectional double ESD protection diode in common-cathode SOT23 configuration, designed for transient overvoltage suppression on up to two signal lines. It delivers 30 kV contact ESD immunity (IEC 61000-4-2 Level 4), 22 V reverse standoff voltage, ≤60 pF capacitance, and clamps at ≤38 V under 1 A 10/1000 µs surge.
For engineers reviewing the MMBZ27VCL datasheet, MMBZ27VCL pinout, MMBZ27VCL application, or MMBZ27VCL equivalent, key selection criteria include bidirectional vs. unidirectional line protection mode, low-capacitance signal integrity preservation, thermal resistance to ambient (350 K/W), and compatibility with FR4 PCB layouts requiring minimal trace length to connectors.
Technical Context
The MMBZ27VCL implements a dual-anode, single-common-cathode topology enabling either independent unidirectional protection of two lines (pins 1→3 and 2→3) or bidirectional protection of one line (pins 1↔2 with cathode grounded). Its silicon junction achieves precise 27 V nominal breakdown (±5%) and ultra-low 5 nA max reverse leakage at 22 V.
Clamping behavior follows IEC 61643-321 10/1000 µs waveform standards, delivering 40 W peak pulse power handling with thermal derating above 25 °C. The device operates across –55 °C to +150 °C ambient, supported by validated SOT23 footprint and reflow/wave soldering profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 22 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range. |
| Breakdown Voltage | 27 V (typ) - Junction avalanche onset at 1 mA; sets ESD clamping threshold baseline. |
| Clamping Voltage | 38 V @ 1 A - Maximum voltage seen by protected line during 10/1000 µs surge; limits IC stress. |
| Diode Capacitance | 48–60 pF @ 1 MHz - Low enough for USB 2.0, HDMI, and audio interfaces without signal degradation. |
| ESD Rating | 30 kV contact discharge - Meets IEC 61000-4-2 Level 4; protects against human-body ESD events. |
| Peak Pulse Power | 40 W - Sustains transient energy per IEC 61643-321 without failure; enables robust board-level protection. |
| Leakage Current | ≤5 nA @ 22 V - Minimizes DC loading on high-impedance sensor or bias networks. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body. Standardized footprint compatible with automated placement and reflow/wave soldering per Figures 11–12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Connects to first signal line requiring unidirectional ESD protection toward ground. |
| 2 | Anode (Diode 2) | Connects to second signal line; enables dual-line protection or bidirectional mode with Pin 1. |
| 3 | Common Cathode | Ground reference node; must be routed with minimal inductance to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection | Enables simultaneous safeguarding of two independent data paths (e.g., D+ and D−) without cross-talk. |
| Bidirectional single-line mode | Supports AC-coupled or bipolar signals (e.g., audio, RS-485) using pins 1 and 2 as symmetrical terminals. |
| Low 48–60 pF capacitance | Preserves signal integrity up to ~100 MHz; suitable for high-speed interfaces without added jitter or rise-time degradation. |
| 30 kV contact ESD rating | Exceeds IEC 61000-4-2 Level 4 requirements; eliminates need for external spark gaps or multi-stage protection. |
| Ultra-low 0.1–5 nA leakage | Prevents DC offset drift in precision analog front-ends and battery-powered sensor nodes. |
Applications
| USB 2.0 Data Lines | Smartphone Audio Jacks |
|---|---|
Use Scenario: Protecting D+ and D− pins of micro-USB or USB-C receptacles from user-handling ESD events. IC Role / Device Role / Timing Role: Unidirectional clamp placed within 3 mm of connector, shunting transients to chassis ground before reaching USB PHY. Use Value: Prevents PHY latch-up or permanent damage while maintaining <1 ns response time and <60 pF loading on 480 Mbps signaling. | Use Scenario: Shielding 3.5 mm TRRS headset jack contacts (left/right/ground/mic) in portable handsets. IC Role / Device Role / Timing Role: Bidirectional protection between tip/ring and ground, leveraging pins 1 and 2 with cathode grounded. Use Value: Enables ±15 kV air discharge compliance without degrading audio bandwidth or introducing audible pop/click artifacts. |
| HDMI CEC Channel | Industrial Sensor Interface |
Use Scenario: Safeguarding the single-wire CEC control line shared across HDMI-connected AV equipment. IC Role / Device Role / Timing Role: Unidirectional clamp (pin 1→3) referenced to system ground, absorbing coupling surges from adjacent TMDS lanes. Use Value: Maintains CEC logic-level integrity (0–3.3 V) during hot-plug events while adding <0.5 ns propagation delay. | Use Scenario: Protecting 4–20 mA current-loop analog inputs in programmable logic controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Reverse-biased clamp (pin 2→3) across input terminals, limiting voltage excursion to ≤38 V during 1 A surge. Use Value: Ensures ADC input stays within absolute maximum ratings, avoiding calibration drift or rail-to-rail saturation. |
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 NUP2114 | Lower 15 kV contact ESD rating; 30 pF typ capacitance; dual-channel unidirectional only. | Limited to lower-risk consumer ports; not rated for industrial surge environments. | Select when cost sensitivity outweighs peak ESD margin and capacitance is critical below 40 pF. |
| Vishay ESD9X3.3S | 3.3 V standoff; 120 W peak power; 15 pF typ capacitance; single-line bidirectional only. | Optimized for low-voltage I/O (e.g., GPIO); unsuitable for 22 V signal rails. | Choose for 3.3 V logic protection where clamping voltage must stay below 7 V. |
Compared with NUP2114 and ESD9X3.3S, the MMBZ27VCL uniquely balances 22 V standoff, 30 kV ESD immunity, and dual-mode flexibility-making it optimal for mid-voltage mixed-signal interfaces where both unidirectional and bidirectional configurations may be deployed on the same board.

FAQ
What is the maximum clamping voltage of the MMBZ27VCL under a 1 A 10/1000 µs surge?
The MMBZ27VCL clamps to a maximum of 38 V when subjected to a 1 A 10/1000 µs pulse per IEC 61643-321, measured from either anode (pin 1 or 2) to the common cathode (pin 3). This value is guaranteed across temperature and ensures downstream ICs remain within safe operating voltage limits during surge events.
Can the MMBZ27VCL protect bidirectional analog signals like audio or RS-485?
Yes-the MMBZ27VCL supports bidirectional protection of a single line by connecting the signal between pins 1 and 2, with pin 3 grounded. Its symmetric unidirectional structure allows conduction in both directions relative to ground, making it suitable for AC-coupled audio paths and differential bus lines where polarity reverses during normal operation.
How does the SOT23 package affect thermal performance in sustained surge conditions?
In sustained surge conditions, the SOT23 package exhibits a junction-to-ambient thermal resistance of 350 K/W (FR4, single-sided copper). This limits continuous power dissipation to 440 mW at 25 °C ambient, but the device is rated for short-duration pulses only-its 40 W peak power capability relies on transient thermal mass, not steady-state conduction.
Is the MMBZ27VCL qualified for automotive applications?
No-the MMBZ27VCL is explicitly designated as non-automotive qualified per Nexperia's revision history (v.2, April 2023). It lacks AEC-Q200 qualification and has not undergone automotive-grade stress testing. For automotive use, Nexperia offers Q-qualified variants such as the PESD5V0S1BA, which must be selected instead.
