Product details
Overview
PESD5V0L2UU-Q from Nexperia is a low-capacitance unidirectional dual-channel ESD protection diode in SOT323 (SC-70) package, designed to safeguard two signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 5 V reverse standoff voltage, 38 pF typical capacitance, and 13 V clamping voltage at 5.5 A. It is qualified to AEC-Q101 and used in automotive infotainment data lines.
For engineers reviewing the PESD5V0L2UU-Q datasheet, PESD5V0L2UU-Q pinout, PESD5V0L2UU-Q application, or PESD5V0L2UU-Q equivalent, this page delivers verified electrical parameters, validated pin functions, automotive-grade reliability context, and real-world protection use cases for high-speed signal interfaces.
Technical Context
This device implements a common-anode dual-diode architecture: pins 1 and 2 serve as independent cathodes (K1, K2), while pin 3 is the shared anode (CA), enabling simultaneous unidirectional protection of two positive-polarity signal lines referenced to ground. Its layout supports compact placement near connectors.
It meets IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) standards with 6.5 A peak pulse current (8/20 µs) and 70 W peak pulse power. The 25 Ω differential resistance and ultra-low leakage (<430 nA at 5 V) preserve signal integrity in high-frequency audio/video and SIM card interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction; sets upper limit for protected line DC bias. |
| Diode Capacitance | 38 pF (typ.) at 1 MHz, 0 V - Low enough for USB 2.0, HDMI, and audio I²S signal paths without distortion. |
| Clamping Voltage | 13 V at 5.5 A (8/20 µs) - Limits transient overvoltage seen by downstream ICs during ESD events. |
| Peak Pulse Power | 70 W - Sustains short-duration surge energy without failure under IEC 61000-4-5 conditions. |
| ESD Withstand | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - Robust immunity for handheld and automotive exterior ports. |
| Differential Resistance | 25 Ω - Minimizes forward-voltage drop during clamping, reducing stress on protected circuitry. |
| Leakage Current | 430 nA max at 5 V - Ensures negligible DC loading on low-power sensor or SIM card detection circuits. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package; dimensions 2.0 mm × 1.25 mm × 0.95 mm, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected signal line; conducts ESD current to common anode when line voltage exceeds VRWM. |
| 2 | K2 (cathode of diode 2) | Connects to second protected signal line; operates independently but shares return path via pin 3. |
| 3 | CA (common anode) | Single ground-return node for both diodes; must be routed with low-inductance connection to system ground. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Two independent cathodes (pins 1 & 2) share one anode (pin 3), enabling discrete protection of two positive-referenced signals without cross-talk. |
| Low 38 pF capacitance | Preserves signal rise/fall times in >100 Mbps interfaces (e.g., USB D+/D−, SIM CLK/DATA), minimizing bit error rate. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to +150 °C junction), vibration, and humidity per discrete semiconductor stress test standard. |
| 13 V clamping at 5.5 A | Ensures protected ICs (e.g., audio codec inputs, SIM interface transceivers) remain below absolute maximum ratings during ESD strikes. |
| Ultra-low 430 nA leakage | Prevents false triggering in high-impedance detection circuits (e.g., SIM card presence sensing) across full operating temperature range. |
Applications
| Automotive Infotainment Interfaces | SIM Card Protection |
|---|---|
|
Use Scenario: Protecting USB 2.0 data lines (D+, D−) and auxiliary analog audio inputs in head unit PCBs exposed to user-accessible ports. IC Role / Device Role / Timing Role: ESD shunt clamp placed within 3 mm of connector, diverting ±15 kV air/±30 kV contact discharges away from USB transceiver and audio ADC inputs. Use Value: Prevents latch-up or gate oxide damage in downstream PHY ICs while maintaining <1 ns added propagation delay due to low capacitance. |
Use Scenario: Shielding SIM card interface lines (CLK, DATA, RESET) in telematics control units where hot-swap events and handling ESD are frequent. IC Role / Device Role / Timing Role: Dual-diode configuration protects both CLK and DATA lines with shared ground return, minimizing board area versus two discrete diodes. Use Value: Enables reliable SIM detection and communication at 1–5 MHz clock rates without signal integrity degradation or false resets from leakage-induced voltage drift. |
| Portable Audio/Video Ports | Industrial HMI Touch Interface |
|
Use Scenario: Guarding HDMI CEC and I²S digital audio traces on portable media players subjected to repeated pocket insertion/removal ESD. IC Role / Device Role / Timing Role: Unidirectional clamping on positive-swing signal lines only; avoids forward conduction during normal bidirectional signaling. Use Value: Maintains 38 pF capacitance across 0–5 V swing, ensuring <0.1 dB insertion loss at 100 MHz and preserving audio channel separation. |
Use Scenario: Securing resistive touch screen controller's X+/X− and Y+/Y− analog sense lines in factory HMIs exposed to operator glove contact ESD. IC Role / Device Role / Timing Role: Two-channel protection with common anode simplifies grounding strategy and reduces routing complexity on 4-layer PCBs. Use Value: Clamps transients to ≤13 V before they corrupt 12-bit ADC readings, preventing mis-touch detection and calibration drift over 10-year service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher capacitance (65 pF typ.), lower clamping (10 V at 4 A), bidirectional configuration (no common anode). | Requires separate ground paths per channel; less suitable for space-constrained automotive USB layouts. | Prefer when lower clamping voltage outweighs capacitance penalty and board layout allows dual ground routing. |
| Vishay ESDE0504P2W | Same SOT323 package, 5 V VRWM, but 0.5 pF lower capacitance (37.5 pF); rated for 10 kV IEC 61000-4-2 only. | Lacks AEC-Q101 qualification; not approved for automotive under-hood or infotainment modules. | Select only for consumer portable electronics where automotive qualification is unnecessary and sub-0.5 pF margin matters. |
Compared with NUP4201MR6T1G and ESDE0504P2W, PESD5V0L2UU-Q uniquely balances AEC-Q101 compliance, 38 pF capacitance, and common-anode dual-cathode topology-making it optimal for automotive USB/SIM protection where board space, reliability, and signal fidelity are jointly constrained.

FAQ
What is the maximum junction temperature rating for PESD5V0L2UU-Q?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. This enables operation in under-hood automotive environments and industrial enclosures with ambient temperatures up to 125 °C when mounted on 2-oz copper with adequate thermal relief.
Can PESD5V0L2UU-Q protect bidirectional signal lines like USB D+ and D−?
No-it is strictly unidirectional and configured for positive-polarity signals only. For true bidirectional protection (e.g., USB 2.0), a dedicated bidirectional dual-diode array such as PESD5V0S2UT is required; using PESD5V0L2UU-Q on bidirectional lines risks forward conduction during negative signal swings.
How does the common-anode architecture affect PCB layout?
The shared anode (pin 3) must connect to a low-inductance ground plane via a short, wide trace or multiple vias. Routing separate ground paths for pins 1 and 2 defeats the design intent and increases clamping impedance; all protected lines must reference the same ground net tied directly to pin 3.
Is the 30 kV ESD rating applicable to both contact and air discharge?
The 30 kV rating applies only to contact discharge per IEC 61000-4-2 Level 4; air discharge rating is 15 kV. Layout practices-such as placing the device within 3 mm of the connector and minimizing stub length-must be followed to achieve these ratings in final assembly.
