Product details
Overview
PESD5V0S2UAT-Q from Nexperia is a unidirectional double ESD protection diode in common-cathode configuration, housed in an SOT23 package. It provides 30 kV IEC 61000-4-2 contact discharge protection, 5 V reverse standoff voltage, and 260 W peak pulse power for up to two data lines-used in CAN bus, USB, and audio interface protection.
For engineers reviewing the PESD5V0S2UAT-Q datasheet, PESD5V0S2UAT-Q pinout, PESD5V0S2UAT-Q application, or PESD5V0S2UAT-Q equivalent, key selection criteria include clamping voltage (20 V at 15 A), diode capacitance (152–200 pF), AEC-Q101 qualification, and common-cathode dual-anode topology for compact bidirectional-line protection.
Technical Context
This device implements two unidirectional ESD protection paths sharing a single cathode terminal, enabling independent but coordinated transient suppression on two signal lines referenced to ground. Its 80 Ω differential resistance and 9 V clamping voltage at 1 A support low-distortion signal integrity in high-speed interfaces.
The SOT23 footprint supports automated placement while maintaining thermal performance up to 150 °C junction temperature. Its 152–200 pF capacitance at 0 V bias and ultra-low 100 nA reverse leakage ensure minimal loading on 5 V logic and analog data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V reverse standoff voltage - ensures no conduction during normal 5 V operation |
| VCL | 20 V clamping voltage at 15 A - limits transient overvoltage to safe levels for downstream ICs |
| Cd | 152–200 pF at 1 MHz - low enough for USB 2.0 and CAN FD signal integrity |
| PPPM | 260 W peak pulse power - handles IEC 61000-4-5 surge events without failure |
| ESD Rating | 30 kV contact discharge per IEC 61000-4-2 Level 4 - exceeds automotive and industrial immunity requirements |
| AEC-Q101 | Qualified - validated for automotive underhood and infotainment applications |
Pinout & Package
SOT23 plastic surface-mounted 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 shared cathode when voltage exceeds VBR |
| 2 | A2 (anode of diode 2) | Connects to second protected line; operates independently but shares cathode return path |
| 3 | CC (common cathode) | Single ground reference point for both diodes; minimizes PCB routing complexity and inductance |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual-diode topology | Reduces component count and board space versus discrete single-diode solutions |
| Ultra-low IRM (100 nA @ 5 V) | Prevents DC loading and signal offset on sensitive analog or low-power digital lines |
| 152–200 pF capacitance | Enables use on 480 Mbps USB 2.0 and 5 Mbps CAN FD without signal degradation |
| 260 W PPPM rating | Withstands repeated 8/20 µs surges up to 15 A without parameter shift or failure |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling, humidity, and mechanical shock |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher VRWM (12 V), higher Cd (300 pF), lower ESD rating (15 kV), same SOT23-3 package | Designed for 12 V systems (e.g., LIN bus); less suitable for 5 V USB/CAN due to capacitance and clamping mismatch | Select only if protecting >10 V rails where higher standoff and tolerance for added capacitance are acceptable |
| Vishay VEML6075TR | Not applicable - optical UV sensor, not an ESD diode; misidentified in cross-reference databases | N/A - incompatible function and package | Exclude from consideration; confirmed non-equivalent via Vishay datasheet and pinout validation |
Compared with NUP4201MR6T1G, PESD5V0S2UAT-Q delivers tighter 5 V system compatibility, lower capacitance for high-speed data, and certified 30 kV ESD robustness-making it preferred for automotive CAN, USB, and audio interfaces where signal fidelity and compliance are critical.

FAQ
What is the maximum operating temperature for PESD5V0S2UAT-Q?
The device supports continuous operation up to 150 °C junction temperature, with derated peak pulse power above 25 °C ambient-verified per Figure 4 in the datasheet. Its SOT23 package enables effective heat dissipation in thermally constrained automotive and industrial PCB layouts.
Can PESD5V0S2UAT-Q protect bidirectional signals like RS-485?
No-it is unidirectional and configured for signals referenced to ground (e.g., CAN_H/L relative to chassis ground). For true bidirectional protection, two devices or a dedicated bidirectional array like PESD5V0X2BT-Q would be required per line.
Is the 30 kV ESD rating applicable to both pins 1 and 2 simultaneously?
Yes-the 30 kV IEC 61000-4-2 contact discharge rating applies individually to each anode (pins 1 and 2) when stressed relative to the common cathode (pin 3), as confirmed in Section 8 Limiting Values and Table 5 of the official datasheet.
Does the marking code %7B indicate RoHS compliance?
Yes-the "%7B" top-side marking includes the "%" placeholder for manufacturing site code and conforms to Nexperia's standardized RoHS-compliant marking scheme; full compliance documentation is available in the product's environmental report (REF: Nexperia Environmental Compliance Statement PESD5V0S2UAT-Q).
