Product details
Overview
PESD15VS2UQ,115 from Nexperia is a unidirectional double ESD protection diode in SOT663 package, designed to protect two signal lines against IEC 61000-4-2 level 4 ESD (30 kV contact), with 15 V reverse standoff voltage, 32–70 pF capacitance at 1 MHz, and clamping voltage of 23 V at 1 A / 40 V at 5 A peak pulse current.
For engineers reviewing the PESD15VS2UQ,115 datasheet, PESD15VS2UQ,115 pinout, PESD15VS2UQ,115 application, or PESD15VS2UQ,115 equivalent, key selection criteria include low capacitance for high-speed data lines, dual-line unidirectional protection topology, clamping performance under 5 A surge (IEC 61000-4-5), and SOT663 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a common-anode dual-diode configuration: pins 1 and 2 serve as independent cathodes, while pin 3 is the shared anode-enabling simultaneous protection of two unidirectional signal paths referenced to the same ground or supply rail. It operates in avalanche breakdown during transients, with specified clamping behavior up to 5 A (8/20 μs).
Designed for signal integrity preservation, its 32–70 pF capacitance (at 0 V bias) and <1 nA reverse leakage at 15 V support USB 2.0, HDMI DDC, and parallel port applications where capacitive loading and DC leakage must be minimized without sacrificing ESD robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before leakage rises significantly; sets upper limit for protected line DC bias. |
| VCL @ IPP = 5 A | 40 V - Clamped voltage during 8/20 μs surge; determines maximum transient overvoltage seen by downstream ICs. |
| Cd @ 1 MHz, 0 V | 32–70 pF - Diode junction capacitance; directly impacts signal rise time and insertion loss on high-speed lines like USB or audio interfaces. |
| IPP max | 5 A - Peak pulse current rating per diode (8/20 μs); defines surge energy handling capability per protected line. |
| VESD (IEC 61000-4-2) | 30 kV contact - ESD immunity level; exceeds IEC level 4 requirement (8 kV contact / 15 kV air), enabling robust end-equipment certification. |
| IRM @ VRWM = 15 V | <1 nA - Reverse leakage current at rated standoff voltage; ensures negligible DC loading on sensitive analog or logic inputs. |
| PPP | 150 W - Peak pulse power per diode (8/20 μs); supports transient energy dissipation without thermal runaway. |
Pinout & Package
SOT663 is a 3-pin ultra-small flat-lead surface-mount plastic package (1.7 × 1.3 × 0.5 mm), optimized for high-density PCB layouts and automated assembly. Its low profile and 2 mm pitch enable placement adjacent to connectors or IC I/O pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected signal line 1 input; connects to trace requiring unidirectional clamping to common anode (pin 3). |
| 2 | Cathode 2 | Protected signal line 2 input; independent clamping path sharing pin 3 anode; enables dual-line protection in single footprint. |
| 3 | Common anode | Shared return node-typically connected to system ground or low-impedance reference plane; defines clamping reference for both diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Single SOT663 device replaces two discrete diodes-reducing board area by >40% and eliminating layout mismatch between protection paths. |
| Low clamping voltage (40 V @ 5 A) | Ensures downstream logic-level interfaces (e.g., 3.3 V or 5 V GPIO) remain within safe absolute maximum ratings during surge events. |
| Ultra-low capacitance (32–70 pF) | Preserves signal integrity on 480 Mbps USB 2.0 or 100 Mbps parallel bus lines without measurable eye diagram degradation. |
| 30 kV ESD immunity (IEC 61000-4-2 contact) | Meets and exceeds industrial and consumer equipment ESD compliance requirements without external shielding or additional stages. |
| Common-anode topology | Enables protection of two signals referenced to the same rail-ideal for differential pairs with shared ground or single-ended buses with common return. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of a USB 2.0 host or peripheral port against user-handling ESD and cable-induced surges. IC Role / Device Role / Timing Role: Unidirectional clamping diode pair limiting transient overvoltage to ≤40 V while maintaining <70 pF total capacitance across both lines. Use Value: Prevents latch-up or gate oxide damage in USB transceivers without degrading 480 Mbps data eye margin or introducing timing skew between D+ and D−. |
Use Scenario: Safeguarding the bidirectional I²C-based Display Data Channel (DDC) lines (SDA/SCL) between source and display. IC Role / Device Role / Timing Role: Dual-cathode diode providing independent clamping for SDA and SCL, referenced to system ground via shared anode (pin 3). Use Value: Maintains I²C timing compliance (≤400 kHz) with sub-nA leakage and <70 pF load, ensuring reliable EDID read/write during hot-plug events. |
| Parallel Printer Port | Industrial Sensor Interface |
|
Use Scenario: ESD hardening of 8-bit data bus (D0–D7), control (STROBE, ACK), and status (BUSY, ERROR) lines in legacy parallel port peripherals. IC Role / Device Role / Timing Role: One PESD15VS2UQ protects two lines; multiple units cover full 17-line interface with matched clamping and minimal board area. Use Value: Enables CE/FCC Class B compliance for printer docks and adapters by suppressing >15 kV contact discharges without adding series resistance or delay. |
Use Scenario: Protecting analog output lines (e.g., 0–10 V or 4–20 mA transmitter outputs) and digital alarm/status lines in factory-floor sensors. IC Role / Device Role / Timing Role: Cathode-to-signal / anode-to-ground configuration clamps positive transients on active-high outputs and negative excursions on grounded-return lines. Use Value: Eliminates field failures from electrostatic discharge during sensor installation/maintenance while preserving millivolt-level accuracy and noise immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z15T5G (ON Semiconductor) | Same SOT523 package but single-channel; requires two devices for dual-line protection; higher capacitance (100 pF typical). | Larger board area needed; less suitable for ultra-dense layouts where SOT663's 3-pin dual function is critical. | Select when existing design uses SOT523 footprints or requires higher VBR (16.7 V min) at cost of capacitance and area. |
| TPD2E007DRYR (Texas Instruments) | 0.65 mm × 0.65 mm DRY package; 3.5 pF capacitance; lower VRWM (7 V); bidirectional configuration. | Not unidirectional; unsuitable for signals biased above ground; better for low-voltage high-speed interfaces like MIPI. | Select only for sub-7 V rails and ultra-low-capacitance needs; avoid where 15 V standoff or unidirectional clamping is required. |
Compared with ESD5Z15T5G and TPD2E007DRYR, PESD15VS2UQ,115 uniquely delivers 15 V standoff, dual-line unidirectional protection, and 32–70 pF capacitance in a single 1.7 × 1.3 mm SOT663 package-making it optimal for space-constrained industrial and computing interfaces requiring robust 30 kV ESD immunity.

FAQ
What is the maximum continuous operating voltage for PESD15VS2UQ,115?
The reverse standoff voltage (VRWM) is 15 V-this is the maximum DC or RMS voltage that can be continuously applied across either diode (pins 1–3 or 2–3) without exceeding specified leakage current (<1 nA). Operation above this voltage risks premature conduction and increased power dissipation.
Can PESD15VS2UQ,115 protect bidirectional signal lines like RS-232 or CAN?
No-it is strictly unidirectional due to its common-anode architecture; it clamps only positive transients relative to the anode (pin 3). For bidirectional protection (e.g., RS-232, CAN), a symmetric dual-diode array or dedicated bidirectional TVS such as PESD5V0S2UAT is required.
How does the SOT663 package affect PCB layout for optimal ESD performance?
Place PESD15VS2UQ,115 within 2 mm of the protected connector; route protected traces directly to pins 1 and 2 with minimal stub length; connect pin 3 to a solid ground plane using ≥2 vias; avoid routing unprotected signals near the device or its ground path to prevent coupling.
Is PESD15VS2UQ,115 suitable for protecting 3.3 V logic I/O lines?
Yes-but verify system-level clamping margin: with 40 V clamping at 5 A, downstream 3.3 V ICs require internal or external secondary protection (e.g., series resistor + local decoupling) to withstand the transient voltage overshoot; the diode prevents catastrophic failure but does not eliminate all stress.
