Product details
Overview
PESD5V0V1BA-Q from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect one high-speed signal line against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (4.8 A, 8/20 µs). It features 11 pF typical capacitance, 5 V reverse standoff voltage, 12.5 V clamping voltage at 4.8 A, and <1 nA leakage at 5 V - enabling use in 10/100 Mbit/s Ethernet and SIM card interfaces.
For engineers reviewing the PESD5V0V1BA-Q datasheet, PESD5V0V1BA-Q pinout, PESD5V0V1BA-Q application, or PESD5V0V1BA-Q equivalent, key selection criteria include low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, bidirectional clamping symmetry, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual-cathode, bidirectional TVS diode implements two back-to-back Zener-like junctions in a single SOD323 package, providing symmetrical clamping for ± transients on a single data line. Its 11 pF capacitance and 35 Ω differential resistance support high-frequency signal paths without distortion.
The device operates within a -55 °C to 150 °C ambient range and sustains 45 W peak pulse power per IEC 61000-4-5. Junction temperature derating follows a defined curve (Fig. 4), and its 0.2 Ω dynamic resistance ensures rapid transient energy dissipation during 8/20 µs surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - defines maximum continuous operating voltage before conduction begins; matches 3.3 V/5 V logic rail protection needs. |
| Diode Capacitance | 11 pF (typ.) at 1 MHz, 0 V - enables minimal signal loading on high-speed lines like USB 2.0 or Ethernet PHY interfaces. |
| Clamping Voltage | 12.5 V at 4.8 A (8/20 µs) - limits transient overvoltage to safe levels for downstream ICs rated ≤13.2 V absolute max. |
| ESD Withstand | ±30 kV per IEC 61000-4-2 (contact) - exceeds Level 4 immunity requirements for industrial and automotive end equipment. |
| Peak Pulse Current | 4.8 A per IEC 61000-4-5 (8/20 µs) - supports robust surge protection for external-facing ports subject to lightning-induced transients. |
| Leakage Current | <1 nA at 5 V - prevents DC bias shift or battery drain in always-on portable electronics and SIM card circuits. |
| Breakdown Voltage | 6.8 V (typ.) at 5 mA - ensures reliable turn-on margin above VRWM while avoiding false triggering during normal operation. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.3 mm pitch, 1.7 mm × 1.25 mm × 0.95 mm body; marking bar denotes cathode side; JEDEC-compliant outline per Fig. 10.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Connects to protected signal line; forms one half of bidirectional clamping path to ground. |
| 2 | K2 (Cathode of Diode 2) | Connects to ground reference; completes symmetrical clamp structure for ± transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Single-device solution for AC-coupled or bipolar signal lines (e.g., audio, RS-485, SIM I/O), eliminating need for dual-diode arrays. |
| AEC-Q101 Qualified | Validated for automotive underhood and infotainment applications; includes stress testing across temperature, humidity, and mechanical shock. |
| Ultra-Low Capacitance | 11 pF typ. ensures <0.5% signal attenuation at 100 MHz - critical for maintaining eye diagram integrity in 10/100 Mbit/s Ethernet links. |
| Low Clamping Ratio | VCL/VRWM = 2.5 - delivers tighter voltage limiting than standard TVS diodes (typically >3.0), improving system-level surge margin. |
| Sub-nA Leakage | <1 nA at 5 V enables direct placement on battery-backed lines (e.g., RTC, SIM VCC) without measurable standby current penalty. |
Applications
| 10/100 Mbit/s Ethernet Interface | SIM Card Slot Protection |
|---|---|
|
Use Scenario: Protecting MDI/MDIX differential pairs in automotive telematics modules against ESD events during connector mating/unmating. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at RJ45 jack, clamping ±8 kV ESD pulses before reaching PHY IC. Use Value: 11 pF capacitance avoids skew between differential signals; 12.5 V clamping preserves PHY's 13.2 V ABSMAX rating with 0.7 V design margin. |
Use Scenario: Shielding SIM VCC, I/O, and CLK lines in mobile hotspots and fleet management gateways from user-handling ESD. IC Role / Device Role / Timing Role: Single-line ESD clamp on each SIM interface signal, mounted adjacent to SIM connector pads. Use Value: <1 nA leakage prevents battery drain in always-on tracking units; AEC-Q101 qualification ensures reliability across -40 °C to +85 °C automotive thermal cycles. |
| Automotive Infotainment Audio Line | USB 2.0 Data Lines (D+/D−) |
|
Use Scenario: Safeguarding analog audio inputs (e.g., AUX-in, microphone) in head units exposed to ESD during cable insertion. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on unbalanced line, referenced to chassis ground via short trace. Use Value: 11 pF capacitance maintains flat frequency response up to 20 kHz; bidirectional operation handles both positive and negative transients on AC-coupled paths. |
Use Scenario: Protecting D+ and D− pins of USB 2.0 host controllers in vehicle diagnostics tools and dashcams. IC Role / Device Role / Timing Role: One PESD5V0V1BA-Q per line, placed within 3 mm of USB connector to minimize inductance in transient return path. Use Value: 35 Ω differential resistance minimizes signal reflection; 12.5 V clamping stays below USB 2.0 PHY's 13.2 V VDDIO absolute maximum, preventing latch-up. |
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 (22 pF typ.), lower clamping (10.5 V at 4 A), same SOD-323 package. | Better for lower-voltage rails (e.g., 1.8 V I/O) but unsuitable for 100 Mbps Ethernet due to bandwidth limitation. | Select when clamping voltage priority outweighs signal integrity; verify layout parasitics do not exacerbate 22 pF impact. |
| Vishay VEML6030X01 | Not applicable - optical sensor, not ESD protection device. | N/A - incorrect functional category; excluded from valid alternatives. | Discard - misidentified part; confirmed non-equivalent by datasheet function and pinning. |
Compared with NUP4105MR6T1G, PESD5V0V1BA-Q offers 45 % lower capacitance for higher-speed interfaces, while maintaining superior 30 kV ESD rating and AEC-Q101 compliance - making it preferred for automotive Ethernet and SIM protection where signal fidelity and qualification rigor are mandatory.

FAQ
Is PESD5V0V1BA-Q suitable for protecting USB 2.0 differential pairs?
Yes - its 11 pF typical capacitance and 35 Ω differential resistance preserve signal integrity up to 480 Mbps. Place one device per line (D+ and D−) within 3 mm of the USB connector, with dedicated low-inductance ground vias. The 12.5 V clamping voltage remains safely below the 13.2 V absolute maximum rating of common USB 2.0 PHYs.
What is the meaning of the 'Q' suffix in PESD5V0V1BA-Q?
The 'Q' suffix indicates AEC-Q101 qualification - confirming full compliance with the Automotive Electronics Council's stress test standard for discrete semiconductors, including temperature cycling, HTRB, and ESD robustness testing. This makes it approved for use in automotive powertrain, body, and infotainment applications.
Can this device protect bidirectional analog audio signals?
Yes - its symmetrical bidirectional clamping (±12.5 V at 4.8 A) and ultra-low leakage (<1 nA) make it ideal for protecting unbalanced analog audio inputs like AUX-in or microphone lines. The 11 pF capacitance introduces negligible phase shift below 20 kHz, preserving audio fidelity without requiring DC blocking capacitors.
How does the SOD323 package affect PCB layout for optimal ESD performance?
Optimal performance requires placing the device within 2 mm of the protected connector, routing traces directly to pins 1 and 2 with no stubs, using a solid ground plane beneath the device, and connecting pin 2 to ground via ≥2 thermal vias. The SOD323's 0.95 mm height allows tight stacking in multi-layer automotive modules while minimizing loop inductance.
