Product details
Overview
PESD5V0U1UA-Q from Nexperia is a unidirectional ESD protection diode in SOD323 package, rated for 5 V reverse standoff voltage, 2 pF typical capacitance at 0 V, 9 kV IEC 61000-4-2 contact discharge immunity, and 1 nA reverse leakage at 5 V - deployed to safeguard high-speed USB and Ethernet signal lines in automotive infotainment systems.
For engineers reviewing the PESD5V0U1UA-Q datasheet, PESD5V0U1UA-Q pinout, PESD5V0U1UA-Q application, or PESD5V0U1UA-Q equivalent, key selection criteria include ultra-low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, clamping voltage under 11 V at 1.3 A pulse, and unidirectional polarity alignment with ground-referenced data lines.
Technical Context
This device operates as a single-line, unidirectional transient voltage suppressor using a silicon PN junction structure optimized for fast response to sub-nanosecond ESD events. Its clamping behavior is defined by a 5.8–8.8 V breakdown voltage (at 5 mA) and a 9.5–11 V clamping voltage at 1.3 A peak pulse current.
The diode exhibits differential resistance ≤100 Ω at 1 mA forward bias and maintains stable capacitance (1.7–2.3 pF at 5 V reverse bias), enabling minimal signal distortion on 10/100/1000 Mbit/s Ethernet and USB 2.0 interfaces where impedance matching and timing skew are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; sets upper limit for protected line DC bias. |
| Diode Capacitance | 2 pF (typ. at 0 V) - Enables <1% signal attenuation on 480 Mbps USB 2.0 channels with minimal rise-time degradation. |
| Clamping Voltage | 9.5 V (max at 1.3 A) - Limits transient overvoltage to safe levels for downstream PHY ICs during IEC 61000-4-2 events. |
| ESD Rating | 9 kV contact discharge (IEC 61000-4-2 Level 4) - Meets automotive EMC requirements for exposed connectors. |
| Reverse Leakage | 1 nA (typ. at 5 V) - Prevents measurable DC loading on high-impedance sensor or audio signal paths. |
| Breakdown Voltage | 6.8 V (typ. at 5 mA) - Defines turn-on threshold for transient suppression without false triggering during normal operation. |
| Junction Temp Limit | 150 °C - Supports operation in under-hood automotive environments with extended thermal cycling. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground; carries transient current during negative ESD events on anode-side signal line. |
| 2 (A) | Anode | Connected to protected signal line; conducts during positive transients when voltage exceeds breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 2 pF typ. at 0 V - Preserves signal integrity on >100 MHz differential pairs without added jitter or reflection. |
| AEC-Q101 qualification | Qualified per Automotive Electronics Council stress test standard - enables use in ADAS camera links and infotainment USB ports. |
| Low clamping voltage | 9.5 V max at 1.3 A - Protects 3.3 V and 5 V logic interfaces without requiring additional series impedance or voltage margin. |
| Unidirectional configuration | Single-PN-junction architecture - Provides precise polarity alignment for ground-referenced data lines like USB D+ and Ethernet TX+/RX+. |
Applications
| USB 2.0 Interface Protection | Ethernet PHY Line Protection |
|---|---|
Use Scenario: ESD protection on USB 2.0 D+ and D− lines of automotive head units and docking stations. IC Role / Device Role / Timing Role: Unidirectional transient suppressor placed between connector and USB transceiver, aligned with signal polarity relative to ground. Use Value: 2 pF capacitance avoids USB eye diagram closure; 9 kV ESD rating meets ISO 10605 for vehicle-level testing. | Use Scenario: Protection of 1000BASE-T Ethernet differential pairs in telematics control units. IC Role / Device Role / Timing Role: Per-line clamp on TX+ and RX+ signals referenced to chassis ground, leveraging unidirectional conduction. Use Value: Sub-11 V clamping prevents PHY latch-up; low leakage avoids baseline shift in auto-negotiation circuits. |
| SIM Card Slot Protection | Automotive Infotainment Audio Line |
Use Scenario: ESD hardening of 3 V SIM interface lines (I/O, CLK, RST) in cellular-connected modules. IC Role / Device Role / Timing Role: Single-diode protection per signal line, mounted adjacent to card edge connector to minimize trace inductance. Use Value: 1 nA leakage ensures no impact on SIM detection logic; 5 V VRWM matches 3 V supply rail with safety margin. | Use Scenario: Transient suppression on analog audio input/output lines (e.g., AUX-in, speaker outputs) in car radios. IC Role / Device Role / Timing Role: Ground-referenced clamp on unidirectional audio paths, placed before amplifier inputs or after DAC outputs. Use Value: 2 pF capacitance prevents audible high-frequency roll-off; AEC-Q101 qualification supports 15-year vehicle service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G | Higher capacitance (15 pF typ.), lower ESD rating (8 kV), same SOD-523 package | Not suitable for >100 Mbps data lines due to bandwidth limitation | Select only for cost-sensitive, low-speed GPIO or button lines where capacitance is non-critical |
| TPD2E001DRYR | Dual-channel, bidirectional, 3.5 pF per channel, 12 kV ESD rating, X2SON-6 package | Requires layout redesign for dual-line protection and lacks AEC-Q101 qualification | Prefer for space-constrained dual-signal applications but verify automotive compliance separately |
Compared with ESD5Z5.0T1G and TPD2E001DRYR, PESD5V0U1UA-Q uniquely balances ultra-low capacitance, automotive qualification, and single-line unidirectional operation - making it optimal for high-speed, safety-critical automotive data interfaces where signal fidelity and regulatory compliance are jointly mandated.

FAQ
What is the maximum clamping voltage of PESD5V0U1UA-Q under IEC 61000-4-2 surge conditions?
The maximum clamping voltage is 11 V at 1.3 A peak pulse current (IPPM), measured per IEC 61000-4-2 8/20 µs waveform. This value ensures downstream 5 V logic interfaces remain within absolute maximum ratings during full-level ESD events, with typical clamping at 9.5 V under the same condition.
Is PESD5V0U1UA-Q suitable for bidirectional signal lines such as USB D+/D− differential pairs?
No - PESD5V0U1UA-Q is unidirectional and must be used per signal line with correct polarity: anode to signal, cathode to ground. For true bidirectional protection (e.g., USB D+), two devices are required back-to-back, or a dedicated bidirectional part like PESD5V0S1BA-Q should be selected instead.
How does the 2 pF capacitance impact 1000BASE-T Ethernet performance?
At 2 pF, insertion loss remains below 0.2 dB up to 125 MHz, preserving return loss >15 dB and maintaining IEEE 802.3ab compliance for Category 5e/6 channel performance. This capacitance avoids skew between differential pairs and prevents echo cancellation errors in gigabit PHYs.
Does the AEC-Q101 qualification cover temperature cycling and humidity exposure?
Yes - AEC-Q101 qualification includes temperature cycling (−40 °C to +125 °C, 1000 cycles), unbiased high-humidity bias (UHAST, 96 h at 130 °C/85% RH), and mechanical shock/vibration tests. The device is rated for −55 °C to +150 °C operating range, supporting under-dash and engine-compartment proximity mounting.
