Product details
Overview
PESD3V3U1UL-Q from Nexperia is a unidirectional ESD protection diode in DFN1006-2 (SOD882) package, designed to protect single high-speed signal lines against electrostatic discharge. It delivers 3.3 V reverse standoff voltage, 2.6 pF typical diode capacitance, 1 nA reverse leakage current at 3 V, and 9 kV IEC 61000-4-2 contact discharge rating for automotive-grade USB and Ethernet interfaces.
For engineers reviewing the PESD3V3U1UL-Q datasheet, PESD3V3U1UL-Q pinout, PESD3V3U1UL-Q application, or PESD3V3U1UL-Q equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, unidirectional clamping behavior, and compact 1.0 mm × 0.6 mm footprint for space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppressor, leveraging silicon PN junction clamping to divert ESD energy to ground when reverse voltage exceeds 4.5 V breakdown threshold. Its low 100 Ω differential resistance ensures minimal clamping voltage rise under 8 kV IEC pulse stress.
The diode is optimized for bidirectional signal line protection with polarity-agnostic placement-cathode connects toward the protected IC side, anode to the connector side-enabling robust protection of both positive- and negative-polarity data lines without polarity inversion concerns.
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 3.3 V logic interfaces. |
| Diode Capacitance | 2.6 pF (typ.) - Enables minimal signal distortion on >1 Gbit/s data lines such as USB 2.0 and 1000BASE-T Ethernet. |
| Breakdown Voltage | 4.5–6.8 V - Ensures reliable turn-on during ESD events while avoiding false triggering during normal operation. |
| Reverse Leakage Current | 1 nA (typ.) at 3 V - Prevents DC loading on sensitive analog or high-impedance signal paths. |
| ESD Rating | 9 kV contact discharge (IEC 61000-4-2 Level 4) - Meets industrial and automotive system-level ESD immunity requirements. |
| Junction Temperature | −55 °C to +150 °C - Supports operation in under-hood automotive environments and thermally demanding portable electronics. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode | Connects toward protected IC side; carries clamped ESD current to ground during negative transients. |

| Low leakage current | 1 nA at 3 V prevents power loss and offset errors in battery-powered portable devices. |
Applications
| USB Interfaces | 10/100/1000 Mbit/s Ethernet |
|---|---|
Use Scenario: Protecting D+/D− lines in USB 2.0 ports against user-handling ESD events during cable insertion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U1U-2/TR | Higher 3.5 pF capacitance; same 3.3 V VRWM and AEC-Q101 qualification. | Marginally lower bandwidth suitability; acceptable for USB 1.1 but marginal for full-speed USB 2.0. | Select if cost sensitivity outweighs sub-3 pF requirement and layout allows minor signal margin reduction. |
| TPD4E001DPYR | Quad-channel array; 3.5 pF per channel; no AEC-Q101 qualification; 3.6 V VRWM. | Requires PCB real estate for four lines; not automotive-qualified; better for consumer PC peripherals. | Choose only for multi-line protection where consolidation reduces BOM count and automotive grade is unnecessary. |
Compared with ESD5V3U1U-2/TR and TPD4E001DPYR, PESD3V3U1UL-Q uniquely combines 2.6 pF capacitance, AEC-Q101 qualification, and single-line optimization-making it the preferred choice for space-constrained, high-speed, automotive-grade signal line protection.

FAQ
What is the maximum clamping voltage of PESD3V3U1UL-Q under 8 kV IEC 61000-4-2 contact discharge?
The peak clamping voltage is 12.5 V at 8 kV contact discharge (measured per IEC 61000-4-2 test setup with 150 pF/330 Ω network). This value ensures downstream ICs with 13.2 V absolute maximum ratings remain within safe operating limits during worst-case ESD events.
Can PESD3V3U1UL-Q be used on bidirectional signal lines like I²C or UART?
Yes, but only with proper polarity orientation: cathode (Pin 1) must face the protected IC, anode (Pin 2) toward the connector. It protects against negative transients on the line and positive transients referenced to ground-suitable for open-drain or push-pull lines where signal swing stays within 0–3.3 V.
Is the DFN1006-2 package compatible with standard reflow soldering profiles?
Yes-the device is qualified for IPC/JEDEC J-STD-020D reflow profiles up to 260 °C peak temperature. Recommended solder paste stencil aperture is 0.3 mm thick with 0.7 mm × 0.4 mm openings per pad, matching the 0.65 mm pitch and 0.6 mm pad width specified in the SOD882 footprint.
Does PESD3V3U1UL-Q require external series impedance for optimal ESD performance?
No external resistor is required for basic ESD suppression. However, adding a 0–10 Ω series resistor near the connector improves high-frequency filtering and reduces ringing during fast transients-particularly beneficial for >500 MHz signal bandwidths where PCB trace inductance dominates.
