Product details
Overview
PESD3V3L1UL from Nexperia is a unidirectional ESD protection diode in SOD882 leadless ultra-small package, designed to protect single high-speed signal lines against electrostatic discharge up to 30 kV (IEC 61000-4-2 contact), with 3.3 V reverse standoff voltage, 34 pF typical capacitance, and 11 V clamping voltage at 4.5 A peak pulse current. It serves as line-level transient suppression in portable electronics interfaces.
For engineers reviewing the PESD3V3L1UL datasheet, PESD3V3L1UL pinout, PESD3V3L1UL application, or PESD3V3L1UL equivalent, key selection criteria include low capacitance for signal integrity, AEC-Q101 qualification for automotive-grade reliability, IEC 61000-4-2 Level 4 compliance, and SOD882 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional clamping diode, conducting only when the protected line exceeds +3.3 V relative to ground - enabling robust protection of positive-polarity signal paths without interfering with normal operation. Its low differential resistance (≤30 Ω) ensures rapid voltage clamping during ESD events.
Designed for single-line protection, it supports surge capability up to 45 W (8/20 µs waveform) and maintains sub-100 nA leakage at 3.3 V, minimizing standby power impact on sensitive analog or high-impedance digital inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line |
| Diode Capacitance | 34 pF (typ.) at 1 MHz - preserves signal integrity on high-speed lines (e.g., USB 2.0, SIM card interfaces) |
| Clamping Voltage | 11 V at IPP = 4.5 A - limits transient overvoltage seen by downstream ICs during worst-case ESD stress |
| ESD Withstand | 30 kV contact discharge (IEC 61000-4-2) - exceeds industrial and automotive system-level ESD immunity requirements |
| Leakage Current | 100 nA (typ.) at VRWM - avoids loading of high-impedance sensor or audio bias networks |
| Peak Pulse Power | 45 W (8/20 µs) - handles surge energy from lightning-induced transients or cable discharge events |
| AEC-Q101 Qualified | Yes - validated for automotive applications including infotainment and body control modules |
Pinout & Package
SOD882 is a leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.5 mm, optimized for automated placement and minimal PCB area usage. Cathode marking is visible on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to ground or reference plane; conducts transient current to GND during overvoltage events |
| 2 | Anode | Connected to protected signal line; blocks reverse current under normal operation, clamps forward surges |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 34 pF enables use on 480 Mbps USB 2.0, FireWire, and audio data lines without signal degradation |
| High ESD robustness | 30 kV contact discharge rating protects against repeated handling and connector mating events |
| Leadless SOD882 footprint | 1.0 × 0.6 mm body reduces PCB real estate by >40% vs. SOD323, supporting ultra-compact mobile designs |
| AEC-Q101 qualification | Validated for temperature cycling, humidity, and mechanical stress per automotive reliability standards |
| Low clamping voltage | 11 V clamping at 4.5 A ensures downstream 3.3 V logic ICs remain within absolute maximum ratings |
Applications
| Cellular Handset Antenna Switch Control | SIM Card Interface Protection |
|---|---|
Use Scenario: Protecting RF switch control lines in LTE/5G handsets exposed to user-handling ESD during antenna tuning. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed directly at connector entry point to shunt ESD pulses before reaching PMIC GPIO. Use Value: 34 pF capacitance avoids detuning of 1–3 GHz RF control paths; 30 kV rating covers IEC 61000-4-2 human-body model exposure. |
Use Scenario: Guarding 1.8 V/3.0 V SIM card data (I/O), clock (CLK), and reset (RST) lines against insertion/removal ESD. IC Role / Device Role / Timing Role: Single-line ESD suppressor mounted adjacent to SIM tray connector to minimize transient loop inductance. Use Value: 100 nA leakage prevents battery drain in always-on SIM detection circuits; SOD882 size fits tight space behind SIM slot. |
| USB 2.0 Data Line Protection | Automotive Infotainment Display Link |
Use Scenario: Safeguarding D+ and D− differential pairs in portable accessories (e.g., OTG cables, docking stations). IC Role / Device Role / Timing Role: One PESD3V3L1UL per line, configured anode-to-signal/cathode-to-GND to preserve DC bias while clamping fast transients. Use Value: 11 V clamping ensures USB PHY receivers (max 3.6 V abs. rating) are not overstressed; 34 pF maintains eye diagram integrity at 480 Mbps. |
Use Scenario: Protecting MIPI D-PHY or FPD-Link II serial video lines between head unit and TFT display in vehicles. IC Role / Device Role / Timing Role: Point-of-entry ESD clamp on each high-speed video lane, leveraging AEC-Q101 qualification for under-hood temperature ranges. Use Value: 45 W surge rating withstands load-dump induced transients; 150 °C max junction temperature supports engine bay proximity mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD9X3.3S | Higher capacitance (65 pF), same 3.3 V VRWM and 30 kV ESD rating | Less suitable for >100 Mbps data lines due to RC filtering effect | Select when cost sensitivity outweighs high-speed signal fidelity requirements |
| TPD2E001DRYR | Dual-channel configuration (2 lines), 12 pF capacitance, 3.6 V VRWM | Requires redesign for single-line use; lower clamping (7.5 V at 1 A) but higher layout complexity | Prefer when protecting multiple adjacent lines (e.g., HDMI CEC + HPD) on same net |
Compared with ESD9X3.3S and TPD2E001DRYR, PESD3V3L1UL delivers optimal balance of ultra-low capacitance, compact SOD882 footprint, and automotive-grade reliability - making it preferred for space-constrained, high-speed single-line protection where signal integrity and qualification are critical.

FAQ
What is the maximum operating temperature for PESD3V3L1UL?
The PESD3V3L1UL has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. This allows deployment in under-hood automotive environments and thermally dense portable electronics without derating, provided PCB copper area and thermal vias meet recommended layout guidelines.
Does PESD3V3L1UL support bidirectional signal lines?
No - PESD3V3L1UL is strictly unidirectional and only clamps positive transients above 3.3 V relative to ground. For bidirectional protection (e.g., USB D+/D−), two devices must be used back-to-back or a dedicated bidirectional part like PESD5V0S1BA should be selected.
How does the SOD882 package affect soldering process compatibility?
The SOD882 package requires reflow soldering only - wave soldering is not recommended. Its leadless construction demands precise stencil aperture design (0.3 mm pad width, 0.7 mm length) and controlled reflow profile (peak 260 °C, 30–60 s above 217 °C) to ensure void-free solder joints and mechanical reliability.
Is PESD3V3L1UL compliant with RoHS and REACH regulations?
Yes - PESD3V3L1UL is manufactured in full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms homogeneous material compliance and provides full substance declarations upon request for supply chain documentation.
