Product details
Overview
PESD3V3L4UF,115 from Nexperia is a low-capacitance unidirectional quadruple ESD protection diode array in an XSON6 (SOT886) leadless ultra-small SMD package, rated for 3.3 V reverse standoff voltage, 22 pF typical diode capacitance, and 20 kV IEC 61000-4-2 contact ESD protection - designed to safeguard four high-speed signal lines in portable electronics interfaces.
For engineers reviewing the PESD3V3L4UF,115 datasheet, PESD3V3L4UF,115 pinout, PESD3V3L4UF,115 application, or PESD3V3L4UF,115 equivalent, key selection criteria include clamping voltage at 3 A (12 V), ultra-low leakage (75 nA max at 3.3 V), and compact 1.0 × 1.45 × 0.5 mm footprint for space-constrained USB, SIM, and audio line protection.
Technical Context
This device implements four independent unidirectional ESD protection diodes sharing two common anode terminals (pins 2 and 5), enabling efficient layout for differential or parallel signal line protection while maintaining low inter-channel coupling. Its architecture supports bidirectional transient suppression on individual lines via grounded common anodes.
Designed for IEC 61000-4-2 Level 4 (±20 kV contact) and IEC 61000-4-5 surge compliance (2.5 A, 8/20 µs), it delivers 30 W peak pulse power per diode with 12 V clamping at 3 A and 8 V at 1 A - critical for preserving signal integrity in high-frequency data paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - maximum continuous operating voltage before conduction; ensures compatibility with 3.3 V logic and interface rails. |
| Diode Capacitance | 22 pF (typ) at 1 MHz, 0 V - enables use on USB 2.0, HDMI, and audio lines without signal degradation. |
| Clamping Voltage | 12 V at 3 A (8/20 µs) - limits transient overvoltage to safe levels for downstream 3.3 V IC inputs. |
| ESD Withstand | 20 kV contact discharge (IEC 61000-4-2) - exceeds industrial and consumer immunity requirements. |
| Leakage Current | 75 nA max at VRWM = 3.3 V - prevents DC loading of sensitive analog or RF signal paths. |
| Peak Pulse Power | 30 W per diode (8/20 µs) - sustains high-energy surges without failure in handheld device ports. |
| Breakdown Voltage | 5.6 V (typ) at 1 mA - provides robust margin above 3.3 V rail while enabling fast turn-on during transients. |
Pinout & Package
XSON6 (SOT886) package: leadless ultra-small outline, body dimensions 1.0 × 1.45 × 0.5 mm, six terminals, bottom-soldered thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (diode 1) | Protected signal line 1 output node; connects to I/O trace before connector. |
| 2 | Common anode | Shared return path to ground or low-impedance reference; must be routed with minimal inductance. |
| 3 | Cathode (diode 2) | Protected signal line 2 output node; isolated from pin 1 to prevent crosstalk. |
| 4 | Cathode (diode 3) | Protected signal line 3 output node; supports three-line interface like SIM card CLK/DAT/IO. |
| 5 | Common anode | Second shared return path; allows dual-grounding strategy or split-plane routing for noise isolation. |
| 6 | Cathode (diode 4) | Protected signal line 4 output node; completes quad-line coverage for full USB D+/D−/ID/VBUS or audio L/R/GND+MIC. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 22 pF typical enables <1% signal distortion on 480 Mbps USB 2.0 data lines. |
| 20 kV ESD protection | Meets IEC 61000-4-2 Level 4 contact discharge - sufficient for handheld device button, port, and display edge zones. |
| Dual common anodes | Pins 2 and 5 allow independent grounding of two diode pairs, reducing mutual interference in mixed-signal layouts. |
| 30 W peak pulse rating | Sustains 8/20 µs surges up to 3 A without parametric shift - validated per IEC 61000-4-5. |
| 12 V clamping at 3 A | Keeps protected IC input voltage below absolute maximum ratings during worst-case ESD events. |
Applications
| USB 2.0 Interface Protection | SIM Card Slot Protection |
|---|---|
Use Scenario: Protecting D+, D−, ID, and VBUS pins of micro-USB connectors in smartphones and tablets against user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed directly at connector entry point, clamping fast-rising ESD pulses before they reach USB PHY IC. Use Value: Prevents latch-up and gate oxide damage in USB transceivers while maintaining <10 ps rise-time fidelity due to 22 pF capacitance. |
Use Scenario: Shielding SIM card interface lines (CLK, DAT, IO, VCC) from electrostatic discharge during hot-insertion and removal. IC Role / Device Role / Timing Role: Quad-channel ESD clamp with dedicated cathodes per line and dual common anodes tied to local ground plane. Use Value: Enables reliable 5 MHz SIM clock operation by limiting transient overshoot to ≤12 V, well below 5.5 V SIM IC absolute max rating. |
| Mobile Audio Jack Protection | Portable Display Data Lines |
Use Scenario: Guarding stereo headphone L/R channels and microphone input against ESD from cable handling and plug insertion. IC Role / Device Role / Timing Role: Low-leakage (75 nA) unidirectional diode array preserving DC bias integrity of electret mic amplifier and audio DAC outputs. Use Value: Maintains THD+N <0.01% at 20 kHz by avoiding capacitive loading beyond 22 pF on analog signal paths. |
Use Scenario: Safeguarding MIPI DSI or LVDS data pairs in OLED/LCD modules against ESD during assembly and field use. IC Role / Device Role / Timing Role: High-speed ESD suppressor with matched channel capacitance ensuring <0.1 dB insertion loss at 500 MHz. Use Value: Preserves eye diagram opening by limiting inter-symbol interference from parasitic capacitance mismatch across four lanes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional quadruple ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PESD3V3L4UG | SC-88A (SOT353) package, 5-pin, single common anode (pin 2), 28 pF capacitance. | Lower board area but higher capacitance; suitable for lower-speed lines (<100 Mbps) and cost-sensitive designs. | Select when PCB real estate permits larger pitch and signal bandwidth is ≤100 MHz. |
| TPD4E05U06DQAR | Texas Instruments part; 6-pin X2SON, 3.3 V, 5.5 pF typ, 10 V clamping at 3 A, 12 kV ESD rating. | Superior high-frequency performance but lower ESD rating; requires tighter layout control for 12 kV compliance. | Choose for RF front-end or high-speed serial links where sub-6 pF capacitance is mandatory and 12 kV suffices. |
Compared with PESD3V3L4UF,115, PESD3V3L4UG trades 6 pF higher capacitance and reduced ESD margin for lower cost and simpler routing, while TPD4E05U06DQAR offers half the capacitance but sacrifices 40% ESD robustness - making the original optimal for balanced 3.3 V, 20 kV, 22 pF protection in mainstream portable interfaces.

FAQ
What is the maximum recommended PCB trace length between PESD3V3L4UF,115 and the protected connector?
Trace length should not exceed 3 mm from each cathode pin to its corresponding signal line entry point, and the common anode traces (pins 2 and 5) must connect to a solid ground plane within 2 mm. Longer traces increase inductance, degrading clamping response and risking overshoot beyond 12 V during 20 kV ESD events.
Can PESD3V3L4UF,115 protect bidirectional signal lines such as I²C or UART?
No - PESD3V3L4UF,115 is unidirectional and only clamps positive transients relative to ground. For bidirectional lines, a separate TVS or back-to-back diode configuration is required. Its architecture assumes signal polarity remains positive with respect to ground, as confirmed in Nexperia's application diagram Figure 9.
Is the thermal pad on the bottom of the SOT886 package electrically connected?
No - the exposed thermal pad in the XSON6 (SOT886) package is non-functional and must be left floating or grounded solely for mechanical stability. Electrical connection would short the internal die substrate and invalidate all specified parameters, including leakage current and clamping behavior.
Does PESD3V3L4UF,115 require external series impedance for optimal ESD performance?
Yes - a 0 Ω or low-value (≤10 Ω) resistor is recommended between each cathode pin and the protected IC input to dampen LC resonance formed with the 22 pF diode capacitance and PCB trace inductance. This improves clamping consistency across the 100 MHz–1 GHz ESD spectrum per IEC 61000-4-2 test methodology.
