Product details
Overview
PESD3V3MS-SF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small SMD package, designed to protect one signal line with 3.3 V reverse standoff voltage, 5 pF capacitance, and ±30 kV IEC 61000-4-2 ESD rating-used in high-speed USB, HDMI, and MIPI interfaces of portable electronics.
For engineers reviewing the PESD3V3MS-SF datasheet, PESD3V3MS-SF pinout, PESD3V3MS-SF application, or PESD3V3MS-SF equivalent, key selection criteria include clamping voltage under 18 A IEC 61000-4-5 surge, dynamic resistance ≤0.11 Ω, and layout-critical low-inductance ground path for effective transient suppression.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling ultra-low clamping voltage (5 V at 18 A) during ESD events while maintaining 3.3 V reverse standoff and 1 mA breakdown at 7 V. Its dual-cathode configuration supports bidirectional protection without polarity constraints on the protected line.
The DSN0603-2 package delivers sub-0.3 mm height and 0.4 mm pitch, minimizing parasitic inductance and enabling placement within 2 mm of I/O connectors-critical for suppressing fast-rising ESD transients (tr ≤ 1 ns) per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous DC voltage the line can sustain before conduction begins. |
| Clamping Voltage | 5 V at 18 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge, limiting stress on downstream logic. |
| Diode Capacitance | 5 pF at 1 MHz - Low enough to avoid signal integrity degradation on 480 Mbps USB 2.0 or 1.5 Gbps MIPI D-PHY lines. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - Meets highest industrial immunity requirement for handheld interface ports. |
| Dynamic Resistance | 0.11 Ω (TLP, ±10 A) - Enables rapid voltage collapse during snap-back, reducing energy dissipation in the protected IC. |
| Breakdown Voltage | 7 V at 1 mA - Ensures reliable turn-on only during transients, avoiding false triggering during normal operation. |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package measuring 0.6 mm × 0.3 mm × 0.3 mm with 0.4 mm pitch and cathode-marked top-side orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to protected signal line; forms first half of bidirectional clamp path to ground. |
| 2 | Cathode (Diode 2) | Connects to same protected signal line; completes symmetrical bidirectional clamping architecture. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or dual-polarity data lines (e.g., USB D+/D−, HDMI TMDS) without external biasing. |
| Ultra-low clamping voltage | 5 V peak at 18 A surge ensures sensitive 3.3 V I/Os (e.g., smartphone AP/SoC GPIOs) remain below absolute maximum ratings. |
| Sub-5 pF capacitance | Preserves signal rise/fall times on high-speed interfaces up to 1.5 Gbps without measurable eye diagram degradation. |
| Extremely low-inductance path | Package geometry and dual-cathode layout minimize transient loop inductance, critical for <1 ns ESD pulse suppression. |
| IEC 61000-4-5 surge robustness | 18 A peak pulse current handling enables compliance with Level 3 (2 kV) surge immunity in industrial port designs. |
Applications
| USB 2.0 Interface Protection | HDMI Type-A Port Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and docking stations against repeated ESD events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at the connector, clamping surges before they reach the USB PHY. Use Value: 5 pF capacitance avoids signal integrity loss at 480 Mbps; 5 V clamping prevents latch-up in 3.3 V USB transceivers. |
Use Scenario: Safeguarding TMDS clock and data channels on HDMI Type-A receptacles in monitors and set-top boxes. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp mounted adjacent to the HDMI connector to suppress ±30 kV contact discharges. Use Value: Sub-0.3 mm profile allows placement within 1.5 mm of edge connector; 0.11 Ω dynamic resistance minimizes voltage overshoot during fast transients. |
| MIPI D-PHY Camera Interface | Industrial RS-485 Transceiver Port |
Use Scenario: Shielding high-speed MIPI D-PHY differential pairs (clock/data lanes) in mobile camera modules from assembly-line ESD. IC Role / Device Role / Timing Role: Dual-cathode ESD diode applied per lane to maintain signal symmetry and impedance continuity. Use Value: 5 pF capacitance ensures <1% rise-time degradation at 1.5 Gbps; snap-back behavior limits clamping time to <10 ns. |
Use Scenario: Protecting RS-485 transceiver inputs in factory automation gateways exposed to cable-discharge events. IC Role / Device Role / Timing Role: Standoff-rated clamp on A/B bus lines, absorbing 18 A surges per IEC 61000-4-5 without thermal runaway. Use Value: 3.3 V VRWM matches common 3.3 V RS-485 PHY supply rails; 125 °C max ambient rating supports enclosed industrial enclosures. |
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 ESDBL3.3D3 | Higher capacitance (12 pF), higher clamping (7.5 V at 18 A), same 3.3 V VRWM and DFN0603 package. | Less suitable for >480 Mbps interfaces due to capacitance; better for lower-speed RS-232 or CAN FD lines. | Select when cost sensitivity outweighs speed requirements and board space permits larger decoupling. |
| Vishay VEML3330A | Lower ESD rating (±20 kV), identical 5 pF and 3.3 V VRWM, but uses SOD-923 package (larger footprint, higher inductance). | Not recommended for compact portable designs where PCB area and inductance are constrained. | Choose only if legacy footprint compatibility with SOD-923 is mandatory and 10 kV ESD margin reduction is acceptable. |
Compared with ESDBL3.3D3 and VEML3330A, PESD3V3MS-SF uniquely balances ultra-low capacitance, sub-5 V clamping, and minimal inductance in the smallest available footprint-making it optimal for space-constrained, high-speed consumer interfaces where signal fidelity and ESD margin are both critical.

FAQ
What is the maximum continuous operating voltage for PESD3V3MS-SF?
The maximum continuous reverse standoff voltage (VRWM) is 3.3 V. This means the device remains non-conductive up to this DC or RMS voltage level on the protected line, ensuring no leakage or interference during normal operation of 3.3 V I/O circuits such as USB PHYs or MIPI receivers.
Can PESD3V3MS-SF be used on differential signal pairs like USB D+/D−?
Yes-each PESD3V3MS-SF protects one bidirectional line. For USB D+/D−, two separate devices are required (one per line), placed individually at the connector. Its symmetrical dual-cathode design ensures identical clamping behavior for positive and negative transients on each line.
How does the snap-back clamping mechanism improve protection performance?
The snap-back structure reduces dynamic resistance to 0.11 Ω after breakdown, collapsing clamping voltage rapidly to 5 V during an 18 A surge. This limits energy transfer to the protected IC far more effectively than standard TVS diodes with higher clamping voltages and slower response.
What PCB layout practices maximize ESD suppression with this device?
Place PESD3V3MS-SF within 2 mm of the I/O connector, route the protected signal directly to its terminal with minimal trace length, connect both cathodes to a solid ground plane using multiple vias, and avoid routing unprotected signals parallel to the protected trace-these steps reduce inductance and prevent coupling.
