Product details
Overview
PESD5V2S2UT-Q from Nexperia is a unidirectional double ESD protection diode in SOT23 package, designed to protect two data or transmission lines against electrostatic discharge. It delivers 30 kV IEC 61000-4-2 contact ESD immunity, 20 V clamping voltage at 15 A surge current, and 152 pF typical capacitance - enabling robust protection for high-speed USB 2.0 and parallel port interfaces in automotive infotainment systems.
For engineers reviewing the PESD5V2S2UT-Q datasheet, PESD5V2S2UT-Q pinout, PESD5V2S2UT-Q application, or PESD5V2S2UT-Q equivalent, key selection criteria include reverse standoff voltage (5.2 V), ultra-low leakage (<150 nA), AEC-Q101 qualification, and dual-cathode/common-anode configuration for independent line protection.
Technical Context
This device implements two separate unidirectional ESD protection paths sharing a common anode (Pin 3), with each cathode (Pins 1 and 2) assigned to one protected line. Its low 80 Ω differential resistance ensures minimal signal distortion during transient events.
The diode operates within a junction temperature range of −65 °C to 150 °C and meets IEC 61000-4-5 surge immunity (15 A, 8/20 µs) alongside full IEC 61000-4-2 Level 4 compliance - making it suitable for harsh automotive environments where signal integrity and reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5.2 V - Ensures no conduction during normal operation of 5 V logic or USB data lines. |
| Clamping Voltage | 20 V at 15 A - Limits transient voltage to safe levels for downstream 5 V ICs during IEC 61000-4-5 surges. |
| Diode Capacitance | 152 pF typical at 1 MHz - Low enough to avoid signal integrity degradation on USB 2.0 (480 Mbps) lines. |
| Peak Pulse Power | 260 W at 8/20 µs - Sustains high-energy transients without failure in automotive ECU interfaces. |
| ESD Rating | 30 kV contact per IEC 61000-4-2 - Exceeds Level 4 requirements for touch-sensitive vehicle controls. |
| Reverse Leakage | 0.15 µA typical at 5.2 V - Prevents DC loading on sensitive analog or high-impedance sensor inputs. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm, 1.9 mm lead pitch), qualified per AEC-Q101 for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line; conducts ESD current to common anode during positive transients. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line; provides independent ESD path without crosstalk. |
| 3 | A (common anode) | Shared return path to ground or supply rail; enables compact dual-line layout with single grounding point. |
Key Features
| Feature | Design Value |
|---|---|
| Dual unidirectional protection | Two independent ESD paths in one SOT23 footprint - reduces PCB area vs. discrete diodes and avoids shared impedance coupling. |
| Low clamping voltage | 20 V max at 15 A - keeps protected ICs below absolute maximum ratings during 8/20 µs surges. |
| Ultra-low leakage | <150 nA at VRWM - eliminates measurable DC error in precision analog sensor front-ends. |
| AEC-Q101 qualification | Qualified for automotive under stress test conditions - supports deployment in engine control, ADAS, and infotainment modules. |
Applications
| USB 2.0 Interface Protection | Automotive Parallel Port |
|---|---|
Use Scenario: Protecting D+ and D− lines of a USB 2.0 host controller in a vehicle head unit against ESD from user connectors. IC Role / Device Role / Timing Role: Unidirectional clamping diode pair providing fast transient response (<1 ns) to divert ESD energy before it reaches the PHY. Use Value: 152 pF capacitance preserves signal rise time; 20 V clamping prevents latch-up in USB transceivers rated for 5.5 V absolute max. | Use Scenario: Safeguarding bidirectional 8-bit parallel data bus between MCU and display driver in dashboard instrumentation. IC Role / Device Role / Timing Role: Dual-line ESD suppressor placed at connector entry point to shunt ±30 kV contact discharges to chassis ground. Use Value: Common-anode architecture allows single-point grounding, minimizing ground bounce across all eight data lines. |
| Audio Line Input Protection | Industrial Communication Port |
Use Scenario: Shielding analog audio input pins (e.g., microphone or line-in) in car audio amplifiers from handling ESD. IC Role / Device Role / Timing Role: High-impedance protection element that remains non-conductive below 5.2 V while clamping transients above breakdown. Use Value: 0.15 µA leakage avoids DC offset errors; 6.8 V typical breakdown ensures compatibility with 5 V biased audio circuits. | Use Scenario: Securing RS-232 or CAN FD auxiliary debug ports on telematics control units exposed to service technician ESD events. IC Role / Device Role / Timing Role: Front-end surge limiter meeting IEC 61000-4-5 (15 A, 8/20 µs) and IEC 61000-4-2 (30 kV) standards simultaneously. Use Value: 260 W peak pulse power rating handles repeated surge events without parametric shift or thermal runaway. |
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 |
|---|---|---|---|
| ESD5V3U2U-2/TR | Higher VRWM (5.3 V), lower capacitance (120 pF typ), same SOT23-3 package and AEC-Q101 grade. | Better suited for 5.3 V tolerant interfaces like some industrial microcontrollers; tighter capacitance spec benefits >1 Gbps links. | Select when lower capacitance is prioritized over marginally higher clamping voltage (22 V). |
| TPD2E007DRYR | Lower VRWM (3.6 V), higher capacitance (18 pF per line), dual-channel but with separate anodes - requires two ground connections. | Optimized for low-voltage mobile interfaces (e.g., HDMI DDC lines); not AEC-Q101 qualified. | Choose only for non-automotive consumer electronics where space and voltage margin allow. |
Compared with ESD5V3U2U-2/TR and TPD2E007DRYR, PESD5V2S2UT-Q offers the best balance of 5.2 V standoff, 20 V clamping, and AEC-Q101 compliance - making it the preferred choice for automotive-grade dual-line protection where reliability and standard compliance are mandatory.

FAQ
What is the maximum operating temperature for PESD5V2S2UT-Q?
The device supports continuous operation up to 150 °C junction temperature and −65 °C to 150 °C ambient temperature, validated per AEC-Q101 thermal cycling and high-temperature operating life tests - confirming suitability for under-hood and dashboard-mounted automotive modules.
Can PESD5V2S2UT-Q protect bidirectional signal lines?
No - it is strictly unidirectional, with cathodes on Pins 1 and 2 and a common anode on Pin 3. For bidirectional protection of a single line, a dedicated bidirectional ESD diode (e.g., PESD5V0S2UAT) is required; this part protects two unidirectional lines independently.
How does the common-anode configuration affect PCB layout?
The shared anode (Pin 3) simplifies grounding by allowing both protected lines to reference the same low-inductance ground node, reducing loop area and improving ESD immunity - but requires careful routing to avoid coupling noise between K1 and K2 traces before reaching the device.
Is PESD5V2S2UT-Q compatible with lead-free reflow soldering?
Yes - it is qualified for standard lead-free reflow profiles (J-STD-020), with a maximum peak temperature of 260 °C and compatibility confirmed for both SnAgCu paste and wave soldering using the footprints defined in Figures 10 and 11 of the official datasheet.
