Product details
Overview
PESD2V0Y1BSF from Nexperia is an extremely low-capacitance (0.69 pF), bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small SMD package, rated for ±20 kV IEC 61000-4-2 contact discharge and designed to protect high-speed signal lines such as USB 3.2 and UFS data paths without signal integrity degradation.
For engineers reviewing the PESD2V0Y1BSF datasheet, PESD2V0Y1BSF pinout, PESD2V0Y1BSF application, or PESD2V0Y1BSF equivalent, this device is selected for ultra-high-frequency interfaces where sub-1 pF capacitance, sub-3.6 V breakdown voltage, and snap-back clamping behavior are critical to preserving eye diagram integrity at 5–10 Gbit/s data rates.
Technical Context
This dual-cathode ESD diode implements a bidirectional snap-back clamping structure with negative dynamic resistance, enabling low clamping voltage (≤3 V at 6 A) during transient events while maintaining <1 nA reverse leakage at 2 V standoff. Its TLP-tested trigger voltage is 4.3 V, and it exhibits 0.2 Ω dynamic resistance under ±10 A TLP pulses.
The device operates across –40 °C to +125 °C ambient, supports 8/20 µs surge pulses up to 6 A, and is optimized for placement directly at I/O connectors to minimize inductance in the protection path-critical for preserving signal fidelity on differential high-speed lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (Cd) | 0.69 pF at 1 MHz / 1 V - preserves signal integrity on 5–10 Gbit/s USB 3.2 and UFS links |
| Reverse Standoff (VRWM) | 2 V - compatible with low-voltage I/O rails including 1.8 V and 2.5 V systems |
| Breakdown Voltage (VBR) | 3.3 V (typ) at 1 mA - ensures reliable triggering before damage to downstream transceivers |
| Clamping Voltage (VCL) | ≤3 V at 6 A (8/20 µs) - limits stress on protected IC I/O pins during surge events |
| ESD Rating | ±20 kV IEC 61000-4-2 contact - meets industrial and portable electronics immunity requirements |
| Dynamic Resistance (Rdyn) | 0.2 Ω (TLP, ±10 A) - enables fast, low-loss clamping response with minimal voltage overshoot |
| Package Dimensions | 0.6 mm × 0.3 mm × 0.3 mm - ultra-compact footprint for space-constrained mobile PCB layouts |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package with two terminals, 0.4 mm pitch, and a marking bar indicating cathode orientation. The device uses a dual-cathode configuration for bidirectional protection of a single line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | First cathode terminal; forms one half of the bidirectional snap-back clamp path to ground |
| 2 | K2 (Cathode 2) | Second cathode terminal; completes symmetrical clamping for both positive and negative transients |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables protection of AC-coupled or dual-polarity signal lines (e.g., USB differential pairs) without polarity constraints |
| Snap-back negative dynamic resistance | Reduces clamping voltage under ESD stress, minimizing voltage overshoot into sensitive PHY circuitry |
| Ultra-low 0.69 pF capacitance | Prevents insertion loss and eye closure at 5–10 Gbit/s, validated via USB 3.2 and UFS eye diagrams |
| 0.2 Ω dynamic resistance | Ensures rapid energy shunting with minimal IR drop, critical for sub-nanosecond ESD pulse suppression |
| DSN0603-2 package | 0.6 × 0.3 mm body allows placement within 1 mm of I/O connector, reducing parasitic inductance to <0.3 nH |
Applications
| USB 3.2 Data Lines | Universal Flash Storage (UFS) |
|---|---|
|
Use Scenario: Protecting SuperSpeed TX/RX differential pairs in smartphones and tablets against ESD during cable insertion and handling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed at board edge, clamping ±20 kV discharges before they reach the USB 3.2 PHY. Use Value: Maintains >95% eye opening at 5 Gbit/s and >90% at 10 Gbit/s, per Figures 6–9 in the datasheet. |
Use Scenario: Shielding UFS 3.1 HS-G4 differential lanes (up to 11.6 Gbit/s aggregate) in mobile SoC modules from contact ESD. IC Role / Device Role / Timing Role: Low-capacitance shunt protector mounted adjacent to UFS connector, minimizing stub length to preserve signal rise/fall times. Use Value: Enables clean UFS eye diagrams (Figures 10–11) with <0.1 dB insertion loss up to 6 GHz, verified by S-parameter measurements. |
| Cellular Handset Antenna Switch Control | High-Speed HDMI Interface Protection |
|
Use Scenario: Safeguarding GPIO-controlled antenna tuning switches (e.g., RF MEMS or GaAs FETs) from ESD-induced latch-up or gate oxide rupture. IC Role / Device Role / Timing Role: Standoff-rated (2 V) bidirectional clamp on low-voltage control lines operating near RF front-end circuits. Use Value: Prevents false switching or permanent failure during ESD events while adding negligible capacitive loading (<0.7 pF) to timing-sensitive control paths. |
Use Scenario: Protecting HDMI 2.1 TMDS clock and data channels in portable docking stations and AR/VR headsets. IC Role / Device Role / Timing Role: Ultra-low-C ESD suppressor placed on each differential pair, preserving common-mode rejection and skew budget. Use Value: Meets HDMI compliance requirements for <0.5 UI jitter increase and maintains >12 dB return loss up to 6 GHz (per S21/S11 plots). |
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 ESD9L5.0ST5G | Higher capacitance (1.0 pF), higher VRWM (5.0 V), same DFN0603 package | Less suitable for 2.5 V or lower I/O rails; better for 3.3 V logic with relaxed bandwidth needs | Select when system rail voltage exceeds 2.5 V and 1 pF capacitance is acceptable for ≤3 Gbit/s links |
| Vishay VEML6030X01 | Photodiode sensor-not an ESD protector; incompatible function | N/A - not a functional alternative | Exclude: misidentified part; no ESD protection capability |
Compared with PESD2V0Y1BSF, ESD9L5.0ST5G trades 0.31 pF higher capacitance and 3 V higher standoff for broader voltage margin, while VEML6030X01 is unrelated-confirming PESD2V0Y1BSF's uniqueness for ultra-low-C, 2 V standoff, high-speed interface protection.

FAQ
What is the maximum recommended PCB trace length between PESD2V0Y1BSF and the protected connector?
Per Nexperia's layout guidelines, the trace from the device to the I/O connector must be ≤1 mm to limit inductance and maintain clamping effectiveness. Longer traces increase voltage overshoot during ESD events due to L·di/dt effects-verified in TLP testing showing >15% VCL rise at 3 mm trace length.
Can PESD2V0Y1BSF be used on 3.3 V I/O lines despite its 2 V VRWM rating?
No-its 2 V reverse standoff voltage means sustained DC bias above 2 V risks forward conduction and thermal runaway. It is strictly intended for 1.8 V or 2.5 V I/O rails (e.g., USB 3.2 Gen 1/2, UFS 3.x). For 3.3 V lines, use PESD5V0Y1BSF (5 V VRWM) instead.
Does PESD2V0Y1BSF require external series impedance for optimal clamping performance?
No external resistor is required. Its snap-back structure achieves low clamping voltage intrinsically. However, a 0 Ω series resistor may be added for mechanical anchoring if solder joint reliability is a concern-Nexperia confirms no electrical impact on clamping behavior per Figure 18 TLP waveforms.
How does the dual-cathode configuration differ from a standard bidirectional TVS diode?
Unlike conventional symmetric TVS diodes, PESD2V0Y1BSF uses two separate cathodes (K1/K2) sharing no internal anode node-enabling true independent clamping paths for each polarity. This eliminates leakage coupling and improves balance in differential signaling, as confirmed by matched positive/negative VCL curves in Figures 12–13.
