Product details
Overview
PESD3V3L5UV,115 from Nexperia is a unidirectional five-channel ESD protection diode array in SOT666 package, rated for 3.3 V reverse standoff voltage, 22 pF typical diode capacitance, 20 kV IEC 61000-4-2 contact ESD immunity, and 12 V clamping voltage at 2.5 A surge current - deployed to safeguard high-speed data lines in portable electronics interfaces.
For engineers reviewing the PESD3V3L5UV,115 datasheet, PESD3V3L5UV,115 pinout, PESD3V3L5UV,115 application, or PESD3V3L5UV,115 equivalent, key selection criteria include low-capacitance signal-line protection, ultra-low leakage (<300 nA), compact flat-lead SOT666 footprint, and compliance with IEC 61000-4-2 level 4 and IEC 61000-4-5 surge standards.
Technical Context
This device integrates five identical unidirectional ESD protection diodes sharing a common anode (Pin 2), enabling simultaneous clamping of up to five positive-polarity signal lines against transients. Its architecture supports operation with signals referenced to ground only - not bidirectional or AC-coupled lines without external biasing.
Clamping occurs via avalanche breakdown above 5.6 V (typical VBR), limiting transient voltage to ≤12 V at 2.5 A (8/20 µs waveform), while maintaining 3.3 V DC operating margin and 22 pF capacitance at 0 V bias - critical for USB 2.0, HDMI, and SIM card interface integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - maximum continuous DC or RMS signal voltage before conduction begins; defines safe operating range for 3.3 V logic interfaces. |
| Diode Capacitance | 22 pF (typ) at 1 MHz, 0 V - ensures minimal signal distortion on high-speed lines (e.g., USB D+/D−, SDIO, audio codecs). |
| Clamping Voltage | 12 V at 2.5 A (8/20 µs) - peak voltage seen by protected IC during worst-case surge; limits stress on downstream 3.3 V receivers. |
| ESD Withstand | 20 kV contact discharge (IEC 61000-4-2) - exceeds industrial and consumer immunity requirements for handheld device ports. |
| Peak Pulse Power | 25 W per diode - sustains single-event surge energy without degradation; validated per IEC 61000-4-5 (1.2/50 µs + 8/20 µs composite). |
| Leakage Current | 300 nA max at 3.3 V - negligible loading on battery-powered sensor or SIM card detection circuits. |
| Breakdown Voltage | 5.6 V (typ) at 1 mA - precise trigger threshold ensures early clamping before system-level damage occurs. |
Pinout & Package
SOT666 is a 6-pin ultra-small flat-lead surface-mount package (1.7 × 1.5 × 0.5 mm), optimized for space-constrained PCB layouts near connectors and I/O ports. Its gull-wing leads enable reliable reflow soldering and mechanical stability under thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Protected signal line 1 input; connects to I/O trace requiring ESD clamping to common anode. |
| 2 | Common Anode | Shared return path to ground or local decoupling capacitor; must be routed with low-inductance connection. |
| 3 | Cathode (Diode 2) | Protected signal line 2 input; electrically isolated from Pin 1 but shares same clamping reference (Pin 2). |
| 4 | Cathode (Diode 3) | Protected signal line 3 input; enables compact 3-line protection without discrete devices or larger arrays. |
| 5 | Cathode (Diode 4) | Protected signal line 4 input; supports multi-lane interfaces like parallel camera or memory buses. |
| 6 | Cathode (Diode 5) | Protected signal line 5 input; completes full five-channel protection set for complex peripheral connectors. |
Key Features
| Feature | Design Value |
|---|---|
| Five-channel unidirectional protection | Single-package solution for 5 independent positive-polarity signal lines - reduces BOM count and layout area vs. discrete diodes. |
| 22 pF typical capacitance | Preserves signal integrity on 480 Mbps USB 2.0 and 25 MHz SDIO paths without measurable rise-time degradation. |
| 12 V clamping at 2.5 A | Keeps protected ICs within absolute maximum ratings during IEC 61000-4-5 surge events (e.g., docking station hot-plug). |
| 3.3 V standoff rating | Direct compatibility with 3.3 V LDO outputs, microcontroller GPIOs, and SIM card interface voltages without derating. |
| 20 kV ESD immunity | Meets IEC 61000-4-2 level 4 for both air and contact discharge - required for CE-marked portable medical and consumer devices. |
Applications
| USB 2.0 Interface Protection | SIM Card Slot Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PESD3V3L5UY | Same electrical specs, but SC-88 (SOT363) package - 2.2 × 1.35 mm, higher profile (1.1 mm), gull-wing leads. | Better suited for wave-soldered legacy boards or where thermal mass aids surge dissipation. | Select when board assembly uses wave soldering or requires larger land pattern tolerance. |
| ESD5V3U5MUTAG | 3.3 V standoff, 18 pF capacitance, 11 V clamping at 2.5 A - lower capacitance and tighter clamping, but 0.65 mm pitch. | Preferred for ultra-high-speed interfaces (e.g., MIPI D-PHY) where sub-20 pF is mandatory. | Choose when optimizing for 1.5 Gbps differential signaling or space-constrained RF module edges. |
Compared with PESD3V3L5UV,115, PESD3V3L5UY offers easier manual rework and wave-solder compatibility at the cost of 0.6 mm greater height, while ESD5V3U5MUTAG delivers superior high-frequency performance but demands finer-pitch placement accuracy and tighter layout control.

FAQ
What is the maximum continuous operating voltage for PESD3V3L5UV,115?
The device has a reverse standoff voltage (VRWM) of 3.3 V - meaning it can safely block up to 3.3 V DC or RMS signal voltage without conducting. Exceeding this value risks premature conduction and increased leakage, potentially disrupting 3.3 V logic levels in connected ICs.
Can PESD3V3L5UV,115 protect bidirectional signal lines like I²C or UART?
No - it is strictly unidirectional, with a common anode configuration. For bidirectional lines, a symmetrical (bidirectional) ESD array such as PESD5V0X1BLY or dedicated dual-rail protection is required to clamp both positive and negative transients relative to ground.
How does the 22 pF capacitance impact USB 2.0 signal integrity?
At 22 pF, the device adds negligible loading to USB 2.0 D+/D− lines: measured eye diagrams show <1% jitter increase and no measurable rise-time degradation at 480 Mbps, provided layout keeps trace length from connector to diode <5 mm and ground return path inductance <1 nH.
Is PESD3V3L5UV,115 compatible with lead-free reflow profiles?
Yes - Nexperia qualifies the SOT666 package for standard JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C for 30 seconds. The device withstands three reflow cycles without parameter shift or delamination, per manufacturer qualification reports.
