Product details
Overview
PESD5V0U1BA-Q from Nexperia is a low-capacitance bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one high-speed signal line against IEC 61000-4-2 level 4 ESD (±10 kV contact), with 2.9 pF typical capacitance at 0 V, 5 nA max reverse leakage, and 5 V reverse standoff voltage - deployed in automotive Ethernet and SIM card interfaces.
For engineers reviewing the PESD5V0U1BA-Q datasheet, PESD5V0U1BA-Q pinout, PESD5V0U1BA-Q application, or PESD5V0U1BA-Q equivalent, key selection criteria include clamping voltage under ±8 kV IEC pulse, differential resistance ≤100 Ω, AEC-Q101 qualification, and layout-critical placement near connectors for high-speed data lines.
Technical Context
This bidirectional dual-cathode ESD diode operates symmetrically across both polarities relative to ground, enabling protection of AC-coupled or bidirectional data lines without polarity constraints. Its clamping behavior is defined by two back-to-back Zener-like junctions, with VBR ≥5.5 V (5 mA) and VCL measured per IEC 61000-4-2 waveform (30 ns rise, 60 ns duration).
The device achieves ultra-low signal distortion via sub-3 pF capacitance at 0 V bias and <2 pF at 5 V bias, critical for preserving signal integrity on 10/100/1000BASE-T Ethernet and USB 2.0 lines. Thermal robustness is ensured by 150 °C max junction temperature and AEC-Q101 stress qualification for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous working voltage before conduction begins; sets safe operating margin for 3.3 V or 5 V signal rails. |
| Diode Capacitance | 2.9 pF (typ, 0 V) - Enables minimal signal loading on >100 MHz data lines such as HDMI DDC or Ethernet MDI. |
| ESD Withstand | ±10 kV IEC 61000-4-2 contact - Meets automotive and industrial immunity requirements without external circuit derating. |
| Reverse Leakage | 5 nA (typ, 5 V) - Negligible current draw in battery-powered portable electronics and SIM card detection circuits. |
| Breakdown Voltage | 5.5–9.5 V (5 mA) - Defines onset of clamping; ensures reliable turn-on before downstream IC damage thresholds. |
| Differential Resistance | ≤100 Ω - Limits clamped voltage spike during transient events, directly determining peak VCL at given IPP. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.3 mm pitch, 1.7 × 1.25 × 0.95 mm body, cathode-bar marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |

Applications
| Automotive Ethernet PHY Protection | SIM Card Interface Protection |
|---|---|
Use Scenario: Protecting 100BASE-T1 or 1000BASE-T1 PHY differential pairs in vehicle ADAS domain controllers. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 3 mm of RJ45 connector, clamping ESD pulses before reaching PHY IC input pins. Use Value: Maintains signal integrity with <3 pF loading while meeting ISO 10605 and IEC 61000-4-2 automotive immunity standards. |
Use Scenario: Guarding 3 V SIM card VCC, I/O, and CLK lines against hot-plug ESD in automotive telematics modules. IC Role / Device Role / Timing Role: Low-leakage (5 nA) clamp preventing false card detection and latch-up during insertion/removal events. Use Value: Eliminates need for separate pull-up resistors or additional filtering due to negligible DC loading on 1.8/3.0 V logic rails. |
| High-Speed Audio Data Lines | Industrial LAN Equipment Ports |
Use Scenario: Shielding I²S or TDM digital audio buses between DSP and codec in automotive infotainment systems. IC Role / Device Role / Timing Role: Symmetric ESD clamp preserving edge rate and jitter performance on multi-MHz serial audio clocks and data lanes. Use Value: Prevents audible pop/click artifacts caused by transient-induced bit errors, verified up to 20 MHz clock rates. |
Use Scenario: Securing 10/100/1000BASE-T RJ45 ports on industrial switches exposed to factory-floor ESD events. IC Role / Device Role / Timing Role: First-line defense mounted directly at port PCB edge, shunting ±10 kV discharges to chassis ground. Use Value: Reduces field failure rate by >95% compared to unclamped designs in CE-marked equipment subjected to EN 61000-4-2 testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (12 pF typ), lower ESD rating (±8 kV), same SOD-323 package | Not qualified to AEC-Q101; limited to consumer-grade USB or audio ports | Select when cost sensitivity outweighs automotive qualification and high-speed signal integrity needs. |
| Vishay VEML6030X01 | Photodiode + integrated signal conditioning; not an ESD diode - functionally incompatible | Optical ambient light sensing, not transient suppression | Exclude - misaligned function; no ESD protection capability. |
Compared with NUP4105MR6T1G, PESD5V0U1BA-Q delivers 4× lower capacitance and certified automotive reliability, making it essential for Ethernet PHY and SIM card protection where signal fidelity and qualification compliance are non-negotiable.

FAQ
What is the maximum clamping voltage of PESD5V0U1BA-Q under IEC 61000-4-2 ±8 kV contact discharge?
The clamping voltage is not explicitly specified in the datasheet as a single value but is determined by the combination of breakdown voltage (5.5–9.5 V), differential resistance (≤100 Ω), and peak pulse current. For ±8 kV IEC testing, typical clamped voltage remains below 15 V at the device terminals when properly laid out with short ground paths.
Can PESD5V0U1BA-Q protect both differential and single-ended signal lines?
Yes - its bidirectional architecture allows protection of either configuration. For differential pairs like Ethernet MDI, one device protects each line to ground; for single-ended lines like SIM CLK, it clamps transients between signal and ground without polarity constraints.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes - Nexperia provides validated reflow footprint dimensions (Fig. 7) and specifies compatibility with JEDEC J-STD-020 moisture sensitivity level 1. The device supports peak temperatures up to 260 °C for ≤30 seconds, matching standard lead-free reflow cycles.
How does AEC-Q101 qualification impact design-in for non-automotive applications?
AEC-Q101 qualification confirms extended temperature operation (−55 °C to +150 °C), robustness against mechanical stress, and reliability under accelerated life testing - providing design margin for industrial, medical, and telecom applications where long-term stability is critical, even outside automotive use cases.
