Product details
Overview
PESD7V1R1BDSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small leadless package, designed to protect high-speed signal lines such as USB4, Thunderbolt 4, and HDMI 2.1. It delivers 0.13 pF typical capacitance at 1 MHz, 7.1 V reverse standoff voltage, and clamps transients to extremely low voltage during ±8 kV contact ESD events.
For engineers reviewing the PESD7V1R1BDSF datasheet, PESD7V1R1BDSF pinout, PESD7V1R1BDSF application, or PESD7V1R1BDSF equivalent, this device is selected for ultra-low-capacitance, high-bandwidth data line protection where insertion loss (-0.28 dB at 10 GHz), return loss (-19 dB at 10 GHz), and 20 Gbps capability are critical design constraints.
Technical Context
This device implements a monolithic snap-back clamping structure with negative dynamic resistance, enabling rapid transition into low-voltage conduction during ESD transients while maintaining sub-1 nA leakage at 7.1 V. Its dual-cathode configuration (K1/K2) supports symmetrical bidirectional protection without polarity dependence.
The DSN0603-2 package provides an ultra-low-inductance path to ground, essential for preserving signal integrity on >10 GHz channels. The 0.6 mm × 0.3 mm × 0.3 mm body and 0.4 mm pitch minimize PCB parasitics, supporting placement directly at I/O connectors per ESD layout best practices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 7.1 V - Maximum continuous DC voltage the line can sustain before conduction begins; sets operating margin for 5 V/3.3 V high-speed interfaces. |
| Diode Capacitance | 0.13 pF at 1 MHz - Enables minimal signal distortion on 20 Gbps differential links (e.g., USB4 Gen 3×2) without equalization overhead. |
| Clamping Voltage | <12 V at 4.8 A (8/20 µs) - Limits transient overvoltage seen by downstream transceivers, preventing latch-up or oxide damage. |
| Leakage Current | 1 nA at 7.1 V - Ensures negligible DC loading on bias-sensitive analog or reference lines adjacent to protected data paths. |
| Insertion Loss | -0.28 dB at 10 GHz - Confirms near-transparent RF performance for millimeter-wave antenna feedlines and high-frequency serial links. |
| Surge Robustness | 4.8 A (8/20 µs) - Validates single-event survivability against IEC 61000-4-5 Level 3 surges in portable electronics with exposed ports. |
Pinout & Package
Package: DSN0603-2 (SOD962-2), ultra-small leadless SMD, 0.6 mm × 0.3 mm × 0.3 mm body, 0.4 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of first ESD clamp diode | Connects to protected signal line; forms one half of symmetrical bidirectional clamping path to ground. |
| 2 (K2) | Cathode of second ESD clamp diode | Connects to same protected signal line; completes bidirectional clamping structure with K1 for ± transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables protection of AC-coupled or floating signal lines (e.g., USB differential pairs) without polarity constraints or external biasing. |
| 0.13 pF capacitance | Preserves eye diagram integrity on 20 Gbps serial links, eliminating need for post-layout equalization tuning in USB4/Thunderbolt 4 designs. |
| Snap-back dynamic resistance | Reduces clamping voltage under fast ESD pulses (IEC 61000-4-2), limiting stress on 28 nm/16 nm transceiver I/O cells. |
| Ultra-low inductance path | Minimizes ground-bounce-induced ringing during transient discharge, critical for maintaining signal fidelity on high-edge-rate data lines. |
Applications
| USB4 / Thunderbolt 4 Data Lines | HDMI 2.1 High-Speed Channels |
|---|---|
Use Scenario: Protecting differential TX/RX lanes in laptop docking stations handling 40 Gbps aggregate bandwidth. IC Role / Device Role / Timing Role: ESD shunt clamp placed within 2 mm of USB-C connector, providing bidirectional transient suppression without degrading jitter or insertion loss. Use Value: Maintains <0.3 dB insertion loss at 10 GHz and preserves 20 Gbps NRZ eye opening, avoiding re-timing or retimer IC dependency. |
Use Scenario: Shielding TMDS clock and data channels in 8K video source devices against ESD during cable hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance shunt protector mounted directly at HDMI Type-A receptacle, minimizing stub length to preserve 6 GHz fundamental frequency response.

IC Role / Device Role / Timing Role: RF-transparent ESD limiter placed between PA output and antenna tuner, rated for continuous RF power handling up to 27 dBm. Use Value: Adds only 0.28 dB insertion loss at 3.5 GHz while surviving 4.8 A surge pulses, eliminating need for separate RF choke + TVS cascaded protection. |
Use Scenario: Securing micro-USB, SIM card, and audio jack interfaces in ruggedized tablets subjected to frequent field ESD exposure. IC Role / Device Role / Timing Role: Single-device bidirectional protector for unidirectional or bidirectional signal lines, reducing BOM count versus discrete diode arrays. Use Value: Achieves 1 nA leakage at 7.1 V and 0.13 pF capacitance, preventing battery drain and capacitive loading on low-power sensor interface lines. |
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 ESDE0402E07-2 | 0.25 pF capacitance (vs. 0.13 pF); 10.5 V clamping at 4.8 A; same DFN0603 package | Higher capacitance limits use to ≤10 Gbps links; suitable for USB3.2 Gen 1 but not USB4 Gen 3×2 | Select when cost sensitivity outweighs 20 Gbps requirement and layout allows minor signal integrity margin loss. |
| Vishay VEML6035X01 | 0.15 pF capacitance; 12.5 V clamping; 3.5 A surge rating; different 0402 footprint (not pin-compatible) | Lower surge robustness and higher clamping reduce safety margin for industrial-grade ESD immunity compliance | Choose only if existing 0402 land pattern prohibits DSN0603-2 adoption and 3.5 A surge rating meets system-level test plan. |
Compared with ESDE0402E07-2 and VEML6035X01, PESD7V1R1BDSF offers the lowest capacitance and tightest clamping among DSN0603-2–footprinted alternatives, making it uniquely suited for 20 Gbps+ differential signaling where both RF transparency and transient suppression must coexist.

FAQ
What is the maximum continuous DC voltage this diode can withstand?
The PESD7V1R1BDSF has a reverse standoff voltage (VRWM) of 7.1 V, meaning it blocks up to ±7.1 V DC on the protected line without entering conduction. This rating ensures compatibility with 5 V and 3.3 V I/O domains while maintaining margin against overshoot during normal operation.
Can this device protect both positive and negative ESD transients on the same line?
Yes - its monolithic bidirectional structure uses two back-to-back cathodes (K1 and K2) to provide symmetrical clamping for ±8 kV IEC 61000-4-2 contact discharges. No external polarity configuration or biasing is required, simplifying layout for differential or AC-coupled signals.
How does the 0.13 pF capacitance impact 20 Gbps data transmission?
At 0.13 pF, the device introduces negligible capacitive loading on differential pairs, preserving signal rise/fall times and eye height. Measured insertion loss of -0.28 dB at 10 GHz confirms minimal attenuation of high-frequency harmonics essential for clean 20 Gbps NRZ eye diagrams without equalization.
Is the DSN0603-2 package compatible with standard 0201 reflow profiles?
Yes - the DSN0603-2 (SOD962-2) footprint matches industry-standard 0201 solder paste stencil recommendations (0.1 mm thickness, 0.256 mm land width). Nexperia provides validated reflow profiles and solder land patterns aligned with IPC-7351B for reliable assembly yield.
