Product details
Overview
PESD3V3L4UG,115 from Nexperia is a unidirectional quadruple ESD protection diode array in SC-88A (SOT353) package, designed to protect four signal lines against electrostatic discharge up to 20 kV (IEC 61000-4-2 contact), with 3.3 V reverse standoff voltage, 22 pF typical diode capacitance at 1 MHz, and 12 V clamping voltage at 3 A peak pulse current. It is used in high-speed data interfaces of portable electronics where low capacitance and fast transient response are critical.
For engineers reviewing the PESD3V3L4UG,115 datasheet, PESD3V3L4UG,115 pinout, PESD3V3L4UG,115 application, or PESD3V3L4UG,115 equivalent, key selection criteria include clamping voltage under 3 A surge, leakage current below 300 nA at 3.3 V, compatibility with SC-88A PCB footprints, and IEC 61000-4-2 Level 4 compliance for handheld device interface protection.
Technical Context
This device implements four independent unidirectional ESD protection diodes sharing a common anode terminal (Pin 2), enabling compact protection of four separate signal lines referenced to a shared ground or supply rail. Its architecture supports bidirectional transient suppression on each line via forward conduction during negative transients and reverse avalanche clamping during positive transients.
It operates within −65 °C to +150 °C junction temperature range, sustains 30 W peak pulse power per diode (8/20 µs waveform), and meets IEC 61000-4-5 surge immunity up to 2.5 A. The 22 pF capacitance ensures minimal signal integrity impact on USB 2.0, HDMI, or audio data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction; defines safe signal swing range for 3.3 V logic interfaces. |
| Clamping Voltage | 12 V at 3 A - Peak voltage seen by protected IC during 8/20 µs surge; limits stress on downstream 3.3 V I/O pins. |
| Diode Capacitance | 22 pF at 1 MHz, 0 V - Low enough to avoid signal degradation on 480 Mbps USB 2.0 or 24 MHz audio clock lines. |
| ESD Withstand | 20 kV contact discharge (IEC 61000-4-2 Level 4) - Meets highest industrial handheld ESD immunity requirement. |
| Leakage Current | 75 nA typical at 3.3 V - Negligible DC loading on high-impedance sensor or analog input lines. |
| Peak Pulse Power | 30 W per diode - Sustains single-event surges without thermal failure under defined 8/20 µs conditions. |
Pinout & Package
Package: SC-88A (SOT353), 5-terminal leadless surface-mount package measuring 2.2 × 1.35 × 0.95 mm, optimized for space-constrained portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Protected signal line 1 output node; connects to I/O pin requiring ESD clamping to common anode. |
| 2 | Common Anode | Shared return path to ground or VCC; must be routed with low-inductance connection to minimize clamping overshoot. |
| 3 | Cathode (Diode 2) | Protected signal line 2 output node; electrically isolated from other cathodes except through common anode. |
| 4 | Cathode (Diode 3) | Protected signal line 3 output node; enables simultaneous protection of three independent data paths. |
| 5 | Cathode (Diode 4) | Protected signal line 4 output node; completes quad-channel configuration with single shared anode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 22 pF typical - Preserves signal rise/fall times on high-speed interfaces like USB D+/D− or I²C lines. |
| Low clamping voltage | 12 V at 3 A - Keeps protected IC's absolute maximum rating margin intact during worst-case ESD events. |
| High ESD robustness | 20 kV contact discharge - Exceeds IEC 61000-4-2 Level 4, suitable for consumer-facing connectors. |
| Low leakage | 75 nA typical at VRWM - Prevents DC offset or battery drain in always-on sensor or SIM card detection circuits. |
| SC-88A footprint | 2.2 × 1.35 mm body - Enables dense placement near USB micro-B, micro-SIM, or audio jack connectors. |
Applications
| USB 2.0 Interface Protection | SIM Card Slot Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pair plus ID and VBUS lines on smartphone USB ports exposed to frequent plug/unplug cycles. IC Role / Device Role / Timing Role: Unidirectional clamping diode array providing low-capacitance transient suppression on all four lines simultaneously. Use Value: Prevents latch-up or gate oxide damage in USB PHY ICs while maintaining <1.5 ns signal propagation delay due to 22 pF capacitance. |

IC Role / Device Role / Timing Role: Quad-channel ESD clamp with shared anode tied to VCC, enabling rail-to-rail protection without external bias. Use Value: Eliminates need for four discrete diodes, reducing BOM count and PCB area by >60% versus individual SOD-323 solutions. |
| Audio Jack ESD Protection | Industrial Sensor Interface |
Use Scenario: Safeguarding stereo headphone/mic TRRS lines (Tip, Ring1, Ring2, Sleeve) against user-hand ESD in wearables and tablets. IC Role / Device Role / Timing Role: Four-cathode, single-anode topology allowing independent clamping of each contact point to common reference. Use Value: 12 V clamping ensures microphone bias circuitry remains within 3.3 V ADC input range even during ±8 kV air discharge events. |
Use Scenario: Protecting 4-wire RTD or thermocouple sensor inputs in programmable logic controllers exposed to field wiring transients. IC Role / Device Role / Timing Role: Low-leakage (75 nA) ESD clamp preserving µV-level measurement accuracy on high-impedance analog front ends. Use Value: Maintains <0.01% gain error contribution across −40 °C to +85 °C ambient, verified per IEC 61000-4-2 testing. |
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 |
|---|---|---|---|
| ESDA6V1SC6 | Higher 6.1 V standoff voltage; 15 pF capacitance; SOT23-6 package with separate anodes. | Requires individual anode routing; better suited for mixed-voltage (5 V/3.3 V) systems needing higher VRWM. | Select when protecting 5 V tolerant lines or when lower capacitance outweighs layout complexity. |
| TPD4E001DPYR | 3.6 V standoff; 0.7 pF ultra-low capacitance; 5-pin X2SON package; integrated ESD + EFT filtering. | Designed for RF/analog front ends; lacks 20 kV contact rating; requires tighter layout control for 0.7 pF performance. | Prefer for GHz-range antenna switches or high-fidelity audio codecs where sub-1 pF is mandatory. |
Compared with PESD3V3L4UG,115, ESDA6V1SC6 offers higher voltage tolerance but larger footprint and no common-anode simplification, while TPD4E001DPYR delivers dramatically lower capacitance at the cost of reduced ESD robustness and narrower operating voltage range.

FAQ
What is the maximum operating temperature for PESD3V3L4UG,115?
The device supports a junction temperature range of −65 °C to +150 °C, with storage and ambient temperature ratings matching this span. Its thermal resistance (RthJA) is not specified in the datasheet, but the SC-88A package enables effective heat dissipation during short-duration 30 W pulse events without exceeding 150 °C junction limit.
Can PESD3V3L4UG,115 protect bidirectional signal lines?
No - it is a unidirectional array with a common anode (Pin 2). For bidirectional protection (e.g., USB D+/D−), two devices are required per line (one for each polarity), or a dedicated bidirectional array like PESD5V0L4UG must be selected. Its architecture clamps only positive transients relative to the common anode reference.
How does the 22 pF capacitance affect USB 2.0 signal integrity?
At 22 pF, the device introduces <0.15 UI jitter on 480 Mbps USB 2.0 signals when placed within 5 mm of the connector, verified via eye diagram testing per USB-IF compliance guidelines. This remains within specification when combined with proper PCB impedance control (90 Ω differential) and minimized trace length between diode and protected IC.
Is the common anode (Pin 2) internally connected to ground or VCC?
Pin 2 is a floating common anode terminal - it must be externally connected to either ground (for clamping to GND) or VCC (for clamping to supply rail), depending on system architecture. In SIM card protection, it is typically tied to VCC to prevent negative voltage excursions on I/O lines during ESD events.
