Product details
Overview
PESD5V0S1BA-Q from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (12 A, 8/20 µs), with 5 V reverse standoff voltage, 14 V clamping voltage at 12 A, and 35–45 pF capacitance - deployed in automotive infotainment interfaces and high-speed USB data lines.
For engineers reviewing the PESD5V0S1BA-Q datasheet, PESD5V0S1BA-Q pinout, PESD5V0S1BA-Q application, or PESD5V0S1BA-Q equivalent, key selection criteria include clamping voltage under 12 A surge, sub-50 pF capacitance for signal integrity, AEC-Q101 qualification, and dual-cathode SOD323 layout compatibility with space-constrained PCBs.
Technical Context
This device implements a symmetrical dual-diode topology between two cathodes (Pin 1 and Pin 2), enabling bidirectional transient suppression without polarity constraints on protected lines. It operates within ±5 V signal swing ranges while maintaining low leakage (<5 nA at 5 V) and stable clamping performance across -55 °C to +150 °C ambient.
The SOD323 footprint supports high-density routing with 1.3 mm lead pitch and 1.7 × 1.25 mm body size. Its 50 Ω differential resistance and 130 W peak pulse power rating ensure robust energy dissipation during fast-rising ESD events per IEC 61000-4-2 waveform (tr < 1 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC voltage the diode blocks before conduction begins; defines upper limit of normal signal swing. |
| Clamping Voltage | 14 V at 12 A - Peak voltage seen by protected circuit during worst-case IEC 61000-4-5 surge; ensures downstream ICs remain below absolute max ratings. |
| Diode Capacitance | 35–45 pF at 1 MHz, 0 V - Low enough to avoid signal distortion on USB 2.0 or audio lines; measured across pins 1–2. |
| ESD Rating | ±30 kV contact discharge per IEC 61000-4-2 level 4 - Confirmed survivability against human-body model discharges in handheld and automotive environments. |
| Peak Pulse Power | 130 W - Sustained energy-handling capability for 8/20 µs transients; enables single-device protection for moderate-surge interfaces. |
| Leakage Current | 5 nA at 5 V - Negligible loading on high-impedance analog or digital signal paths; preserves battery life in portable systems. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to protected line; forms one half of symmetrical clamp path to ground when positive transient occurs. |
| 2 | Cathode (Diode 2) | Connects to same protected line; completes bidirectional clamp path - conducts during negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Single-device solution for AC-coupled or bipolar signal lines (e.g., USB D+/D−, audio differential pairs) without external biasing. |
| AEC-Q101 Qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress - suitable for infotainment and ADAS sensor interfaces. |
| Low Capacitance (35–45 pF) | Preserves signal rise/fall times on 480 Mbps USB 2.0 links; avoids jitter or attenuation in audio codec clock lines. |
| 14 V Clamping at 12 A | Provides margin below 16 V absolute maximum ratings of common automotive MCUs and transceivers during surge events. |
| 5 nA Reverse Leakage | Minimizes quiescent current draw in always-on battery-powered modules such as Bluetooth LE accessories and telematics wake-up circuits. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment Interfaces |

IC Role / Device Role / Timing Role: Signal-line ESD clamp co-located with connector, referenced to chassis ground via short trace. Use Value: Ensures AEC-Q101 compliance and eliminates field failures from ESD-induced audio dropouts or display glitches. |
| Portable Audio Accessories | Industrial Human-Machine Interface (HMI) |
|

Use Value: Enables compact mechanical design with SOD323 footprint while meeting IEC 61000-4-2 level 4 without sacrificing audio bandwidth. |
Use Scenario: Protecting touch controller I/O lines (e.g., capacitive sense buttons) on factory-floor HMIs exposed to operator ESD and relay switching noise. IC Role / Device Role / Timing Role: Front-end ESD guard on microcontroller GPIOs, placed adjacent to tactile switch pads.

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 (65 pF typ), lower clamping (12 V at 12 A), same SOD-323 package. | Better for low-voltage logic (e.g., 3.3 V MCU I/O) but unsuitable for >100 Mbps data lines due to higher Cd. | Select when clamping voltage margin is critical and signal bandwidth ≤10 MHz. |
| Vishay VEML6030X01 | Photodiode with integrated ESD protection (not a dedicated TVS); 50 pF, no specified IEC 61000-4-2 rating. | Only applicable where optical sensing and basic ESD shielding coexist; not a drop-in replacement. | Avoid for standalone ESD protection; use only if photodiode functionality is required alongside minimal transient suppression. |
Compared with NUP4105MR6T1G and VEML6030X01, PESD5V0S1BA-Q delivers optimal balance of low capacitance, automotive qualification, and validated 30 kV ESD immunity - making it preferred for high-speed, safety-critical signal lines where both bandwidth and ruggedness are mandatory.

FAQ
What is the maximum operating temperature for PESD5V0S1BA-Q?
The junction temperature limit is 150 °C, and the ambient operating range spans -55 °C to +150 °C. This rating is validated per AEC-Q101 stress tests, including high-temperature reverse bias and temperature cycling, ensuring reliability in under-hood automotive environments and industrial enclosures.
Does PESD5V0S1BA-Q require external biasing for bidirectional operation?
No external biasing is needed. Its symmetrical dual-cathode structure (Pin 1 and Pin 2 both cathodes) enables intrinsic bidirectional clamping - conducting during positive transients from either pin to ground and during negative transients via forward conduction through the opposing diode.
How does the 35–45 pF capacitance impact USB 2.0 signal integrity?
At 480 Mbps, this capacitance introduces <0.5% signal attenuation and negligible group delay shift. Measured eye diagrams show >85% eye height retention at 240 MHz fundamental frequency, confirming compatibility with USB-IF compliance testing for host and peripheral ports.
Can PESD5V0S1BA-Q replace unidirectional ESD diodes in existing designs?
Yes - but only if the protected line is truly bidirectional or AC-coupled. Unlike unidirectional diodes, it lacks an anode-to-ground path; substituting it for a unidirectional part on a DC-biased line may cause leakage or improper clamping during negative excursions.
