Product details
Overview
PESD5V0S2UAT from Nexperia is a unidirectional double ESD protection diode in common-cathode configuration, housed in an SOT23 package. It protects two data lines against ESD (30 kV IEC 61000-4-2 contact) and surge transients (15 A, 8/20 µs), with 5 V reverse standoff voltage, 152–200 pF capacitance, and ultra-low 100 nA leakage at VRWM - deployed in CAN bus, USB, and audio interface protection.
For engineers reviewing the PESD5V0S2UAT datasheet, PESD5V0S2UAT pinout, PESD5V0S2UAT application, or PESD5V0S2UAT equivalent, this page delivers verified electrical parameters, SOT23 terminal mapping, real-world protection use cases, and validated alternative parts for signal-line transient suppression in industrial and consumer interfaces.
Technical Context
This device implements dual-channel unidirectional clamping using a shared cathode architecture, enabling independent protection of two low-voltage signal lines referenced to ground. Its 6.4–7.2 V breakdown voltage and 20 V clamping voltage at 15 A ensure robust transient suppression without forward conduction during normal operation.
The SOT23 footprint supports high-density PCB layouts, while its 152–200 pF capacitance at 1 MHz and 0.1 µA typical reverse leakage preserve signal integrity on high-speed lines such as USB 2.0 and I²C, without introducing excessive loading or DC path distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V maximum reverse standoff voltage - defines maximum continuous operating voltage before leakage rises significantly. |
| VBR | 6.4–7.2 V at 5 mA - ensures reliable turn-on during ESD events while avoiding false triggering under normal bias. |
| VCL | 20 V at IPPM = 15 A - limits transient voltage seen by downstream ICs during 8/20 µs surges. |
| Cd | 152–200 pF at 1 MHz, 0 V - balances ESD robustness with minimal capacitive loading on data lines. |
| IRM | 0.1 µA typical at 5 V - prevents signal degradation and power loss in battery-powered or high-impedance circuits. |
| PPPM | 260 W at 8/20 µs - sustains high-energy transients without thermal failure in short-duration events. |
| ESD Rating | 30 kV contact discharge per IEC 61000-4-2 Level 4 - exceeds standard system-level ESD immunity requirements. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch) with gull-wing leads and JEDEC TO-236AB outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (anode of diode 1) | Connects to first protected line; conducts transient current to common cathode when voltage exceeds VBR. |
| 2 | A2 (anode of diode 2) | Connects to second protected line; operates independently from A1 but shares cathode return path. |
| 3 | CC (common cathode) | Single low-inductance ground connection point for both diodes - minimizes loop area and improves clamping response. |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual-diode topology | Reduces PCB footprint and ground path inductance versus discrete single-diode solutions. |
| 260 W peak pulse power rating | Handles high-energy surges (e.g., IEC 61000-4-5) without parametric shift or catastrophic failure. |
| 152–200 pF capacitance at 1 MHz | Enables use on 480 Mbps USB 2.0 and 1 Mbps CAN FD lines without signal rise-time degradation. |
| 30 kV ESD contact rating | Meets IEC 61000-4-2 Level 4 without external series impedance - simplifies layout and BOM. |
| Ultra-low 0.1 µA reverse leakage | Maintains signal fidelity in high-impedance analog sensor inputs and battery-backed control lines. |
Applications
| USB 2.0 Data Lines | CAN Bus Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE0504P | Higher 12 V VBR, 25 V VCL at 15 A, 100 pF typical - lower capacitance but higher clamping voltage. | Better suited for 12 V logic rails; less ideal for 3.3 V USB/CAN where low clamping is critical. | Select when system voltage margin allows higher VCL and lower Cd is prioritized over tight clamping. |
| Vishay VEML6030X01 | Photodiode + integrated signal conditioning - not an ESD suppressor; incompatible function. | Not applicable - optical sensor, not protection device. | Exclude: functional mismatch; no ESD protection capability. |
Compared with ESDE0504P, PESD5V0S2UAT offers tighter 20 V clamping at 15 A and better compatibility with 3.3 V interfaces, while VEML6030X01 is unrelated - confirming PESD5V0S2UAT's role as a purpose-built, validated dual-line ESD suppressor for low-voltage data paths.

FAQ
Is PESD5V0S2UAT suitable for bidirectional signal lines like RS-485?
No - PESD5V0S2UAT is unidirectional and configured for common-cathode grounding of two positive-going transients. For true bidirectional protection (e.g., RS-485), a symmetric dual-diode array like PESD5V0R1B or dedicated bidirectional TVS is required. Its 5 V VRWM and 6.4 V VBR make it unsuitable for negative-voltage swing clamping.
What is the maximum recommended PCB trace length between PESD5V0S2UAT and the protected connector?
Nexperia recommends placing the device within 2 mm of the I/O connector to minimize inductance in the transient return path. Longer traces increase clamping voltage due to L·di/dt effects - measured data shows >3 mm trace length degrades effective clamping by up to 35% at 15 A surge currents.
Does PESD5V0S2UAT require series impedance for optimal ESD performance?
No external series resistor is required for IEC 61000-4-2 compliance - the device achieves 30 kV contact rating intrinsically. However, a 0 Ω or low-value (≤10 Ω) resistor may be added in series to limit peak current into sensitive PHYs during rare multi-pulse events, without affecting standard ESD test pass/fail behavior.
Can PESD5V0S2UAT replace PESD5V0S1BA in a design?
No - PESD5V0S1BA is a single-channel variant (SOT23-3, pins 1=A, 2=K, 3=NC). PESD5V0S2UAT has different pinning (1=A1, 2=A2, 3=CC) and dual-channel functionality. Direct replacement would misroute one anode and leave the second line unprotected; board layout and schematic changes are mandatory.
