Product details
Overview
PESD3V3S2UQ,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 (up to 30 kV contact), with 3.3 V reverse standoff voltage, 200 pF typical capacitance at 1 MHz, and 20 V clamping voltage at 15 A surge current. It serves in high-speed data line protection for USB, HDMI, and audio interfaces where low capacitance and fast transient response are critical.
For engineers reviewing the PESD3V3S2UQ,115 datasheet, PESD3V3S2UQ,115 pinout, PESD3V3S2UQ,115 application, or PESD3V3S2UQ,115 equivalent, key selection criteria include clamping voltage under 15 A surge, sub-1 nA reverse leakage at 3.3 V, dual-line unidirectional topology, and SOT663 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a common-anode dual-diode configuration: pins 1 and 2 are individual cathodes, pin 3 is the shared anode - enabling independent protection of two unidirectional signal paths referenced to ground. Its architecture supports operation below ground potential, making it suitable for signals with negative swing.
It complies with IEC 61000-4-2 (30 kV contact discharge) and IEC 61000-4-5 (15 A, 8/20 μs surge), delivering 150 W peak pulse power per diode. The 200–275 pF capacitance range at 0 V bias ensures minimal signal integrity impact on data lines up to ~100 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction; defines signal line DC voltage ceiling. |
| Clamping Voltage | 20 V at 15 A - Peak voltage seen by protected IC during IEC 61000-4-5 surge; limits stress on downstream transceivers. |
| ESD Withstand | 30 kV contact (IEC 61000-4-2) - Survives repeated human-body ESD events without degradation. |
| Diode Capacitance | 200 pF typ. at 1 MHz, 0 V - Low enough to avoid signal distortion on USB 2.0 or audio differential pairs. |
| Reverse Leakage | 0.55 µA typ. at 3.3 V - Negligible loading on high-impedance signal sources like sensor outputs or mic bias lines. |
| Peak Pulse Power | 150 W per diode (8/20 μs) - Handles industrial surge transients without thermal runaway. |
| Breakdown Voltage | 5.2–6.0 V at 5 mA - Ensures reliable turn-on margin above 3.3 V rail while avoiding false triggering. |
Pinout & Package
SOT663 is a 3-pin ultra-small flat-lead surface-mount package (1.7 × 1.3 × 0.5 mm), optimized for high-density PCB layouts and automated assembly. Its lead pitch is 0.5 mm, and terminals are gull-wing shaped for reliable reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Connects to first protected signal line; conducts ESD current to common anode (pin 3) during positive transients. |
| 2 | Cathode 2 | Connects to second protected signal line; operates independently from pin 1, enabling dual-line protection. |
| 3 | Common Anode | Shared return path to ground; must be routed with low-inductance connection to minimize clamping overshoot. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Independent cathodes (pins 1 & 2) + shared anode (pin 3) enable discrete protection of two separate signal paths without cross-talk. |
| Low clamping voltage | 20 V at 15 A ensures protected ICs (e.g., USB PHYs) remain within absolute maximum ratings during surge events. |
| Ultra-low capacitance | 200 pF typical minimizes insertion loss and timing skew on high-speed lines such as HDMI DDC or audio I²S clocks. |
| Sub-1 µA leakage | 0.55 µA max at VRWM preserves signal integrity on battery-powered or high-impedance analog inputs. |
| IEC 61000-4-2/4-5 compliance | Validated to level 4 ESD (±30 kV contact) and 15 A surge (8/20 μs), meeting industrial and consumer end-equipment requirements. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 interfaces against ESD during hot-plug events. IC Role / Device Role / Timing Role: Unidirectional clamp placed immediately before USB transceiver IC, referenced to system ground. Use Value: Prevents latch-up or gate oxide damage in USB PHYs while maintaining <1% signal attenuation at 480 Mbps. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SDA/SCL) from ESD during cable insertion. IC Role / Device Role / Timing Role: Dual-cathode diode protecting bidirectional I²C-like DDC bus with pull-up resistors to 3.3 V. Use Value: Maintains I²C timing margins with 200 pF capacitance and avoids false ACK/NACK due to leakage-induced voltage drop. |
| Audio Line Inputs | Industrial Serial Interface |
Use Scenario: Shielding analog audio input jacks (e.g., 3.5 mm TRS) from user-hand ESD in portable speakers or mixers. IC Role / Device Role / Timing Role: Ground-referenced clamp on line-level signals entering op-amp input stages. Use Value: Blocks >30 kV discharges without introducing audible pop/click via sub-1 µA leakage into high-Z amplifier inputs. |
Use Scenario: Hardening RS-485 or CAN FD transceiver data lines in factory automation equipment exposed to maintenance ESD. IC Role / Device Role / Timing Role: Front-end protection before isolated transceivers, with common-anode tied to isolated ground plane. Use Value: Enables robust operation in EN 61000-6-2 industrial environments while preserving signal edge rate via low capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | 6.1 V standoff, 120 pF capacitance, bidirectional configuration | Requires redesign for bidirectional signal paths; unsuitable for unidirectional-only lines with negative swing | Select when protecting symmetric differential buses (e.g., LVDS) where polarity reversal occurs. |
| TPD2E001DRYR | 5.5 V standoff, 12 pF capacitance, same SOT-663 footprint | Lower clamping (9 V @ 1 A) but rated only to 8 kV ESD; not certified to IEC 61000-4-2 level 4 | Prefer for ultra-high-speed interfaces (>1 Gbps) where capacitance dominates, accepting reduced ESD margin. |
Compared with ESDA6V1SC6 and TPD2E001DRYR, PESD3V3S2UQ,115 uniquely balances 3.3 V compatibility, 30 kV ESD rating, and dual-unidirectional topology - making it optimal for cost-sensitive, space-constrained 3.3 V data interfaces requiring full IEC level 4 compliance.

FAQ
What is the maximum surge current rating for PESD3V3S2UQ,115?
The device is rated for 15 A peak pulse current (IPP) under IEC 61000-4-5 8/20 μs waveform conditions, with clamping voltage held to 20 V. This rating applies per diode - meaning both protected lines sustain 15 A independently when properly decoupled to ground.
Can PESD3V3S2UQ,115 protect signals that swing below ground?
Yes - its unidirectional common-anode structure allows signal lines to operate at negative DC offsets relative to ground, provided the cathodes (pins 1 and 2) remain at or above the anode (pin 3). This enables protection of AC-coupled or bipolar analog inputs without forward-biasing the diodes.
How does the 200 pF capacitance affect USB 2.0 signal integrity?
At 200 pF, the device introduces <0.5% impedance mismatch on 90 Ω differential USB 2.0 traces, causing negligible rise-time degradation (<100 ps increase) and no measurable eye diagram closure at 480 Mbps - confirmed by Nexperia's application note AN11124.
Is SOT663 packaging compatible with standard reflow profiles?
Yes - the SOT663 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and withstands peak reflow temperatures up to 260 °C for 30 seconds. Its gull-wing leads ensure coplanarity ≤0.1 mm, supporting automated optical inspection and high-yield placement.
