Product details
Overview
PESD5V0S4UD-Q from Nexperia is a quadruple unidirectional ESD protection diode array in SOT457 (SC-74/TSOP6) package, designed to protect four signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 5 V reverse standoff voltage, 13 V clamping at 20 A, and 165–220 pF capacitance - deployed in SIM card interfaces and high-speed data ports.
For engineers reviewing the PESD5V0S4UD-Q datasheet, PESD5V0S4UD-Q pinout, PESD5V0S4UD-Q application, or PESD5V0S4UD-Q equivalent, key selection criteria include clamping voltage under 20 A surge, leakage current below 200 nA at 5 V, diode capacitance ≤220 pF for signal integrity, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device implements four independent unidirectional ESD protection paths between cathodes (pins 1, 3, 4, 6) and a shared common anode (pins 2 & 5), enabling compact protection of bidirectional or mixed-polarity signal lines without internal series resistance or integrated TVS topology. It uses silicon avalanche diode junctions optimized for fast response (<1 ns rise time per IEC 61000-4-2).
Clamping behavior is defined by a typical VCL of 13 V at IPP = 20 A (8/20 µs), with differential resistance of 25 Ω and breakdown voltage of 6.4–7.2 V at 1 mA - ensuring robust transient suppression while maintaining low forward conduction loss during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before leakage rises significantly; sets upper limit for protected line DC bias. |
| Clamping Voltage | 13 V at 20 A - Peak voltage seen by protected IC during IEC 61000-4-5 surge; ensures downstream logic remains within safe voltage margin. |
| Diode Capacitance | 165–220 pF at 1 MHz - Directly impacts signal integrity on high-speed lines (e.g., USB 2.0, SIM I/O); requires layout compensation. |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 - Validates immunity to human-body ESD events in handheld and automotive infotainment interfaces. |
| Peak Pulse Power | 200 W - Sustains short-duration transients without thermal runaway; derates above 25 °C per Fig. 4. |
| Leakage Current | 80 nA typical at 5 V - Minimizes standby power loss and avoids false triggering in low-current sensor or battery-backed circuits. |
Pinout & Package
SOT457 (SC-74 / TSOP6) is a 6-pin, surface-mount plastic package measuring 3.1 × 1.7 × 1.1 mm (L × W × H), with gull-wing leads and pin 1 index marked as "K5" on top-side silkscreen.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | ESD current sink for protected line 1; connects to I/O trace before connector. |
| 2 | Common Anode | Shared return path to ground or low-impedance reference; must be routed with minimal inductance. |
| 3 | Cathode 2 | ESD current sink for protected line 2; electrically isolated from pin 1 but shares anode node. |
| 4 | Cathode 3 | ESD current sink for protected line 3; supports independent routing for multi-line protection. |
| 5 | Common Anode | Redundant anode terminal (same net as pin 2); improves current sharing and reduces bond wire inductance. |
| 6 | Cathode 4 | ESD current sink for protected line 4; completes quad-channel configuration in single footprint. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel unidirectional protection | Four independent cathode-to-common-anode paths enable discrete protection of 4 signal lines without cross-talk or shared failure mode. |
| AEC-Q101 qualified | Validated for automotive environments including temperature cycling (-65 °C to +150 °C), humidity, and mechanical shock per discrete semiconductor stress test standard. |
| Low clamping with high surge rating | 13 V clamping at 20 A (IEC 61000-4-5) combined with 200 W peak pulse power ensures robustness against both ESD and lightning-induced surges. |
| Ultra-low leakage | 80 nA typical reverse leakage at 5 V enables use in always-on, low-power applications such as SIM card detection and wake-on-RX circuits. |
Applications
| Cellular Handset SIM Interface | Automotive Infotainment USB Port |

| Portable Audio Codec Interface | Industrial HMI Touch Controller Bus |
Use Scenario: Safeguarding I²S and I²C control lines between audio codec IC and application processor in wireless earbuds and Bluetooth speakers. IC Role / Device Role / Timing Role: Low-capacitance ESD shunt on bidirectional clock/data lines; placed adjacent to codec package to minimize stub length.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U4-2/TR | Higher VRWM = 5.3 V; lower Cd = 120 pF typ; same SOT457 package and AEC-Q101 rating. | Better suited for 5 V tolerant I/O with tighter capacitance budget (e.g., MIPI D-PHY), but slightly higher clamping at 20 A (14.5 V). | Select when signal bandwidth exceeds 300 MHz and system-level clamping margin allows +1.5 V overhead. |
| TPD4E001DPYR | Lower VRWM = 3.6 V; higher Cd = 250 pF max; same 4-channel unidirectional architecture in X2SON-8 package. | Optimized for 3.3 V systems with space-constrained layouts; lacks AEC-Q101 qualification and has reduced surge rating (12 A). | Prefer for cost-sensitive consumer electronics where automotive qualification is not required and PCB area permits larger footprint. |
Compared with ESD5V3U4-2/TR and TPD4E001DPYR, PESD5V0S4UD-Q delivers the best balance of 5 V compatibility, 20 A surge handling, and AEC-Q101 validation - making it the default choice for automotive-grade quad-line protection where clamping voltage and leakage are tightly constrained.

FAQ
What is the maximum recommended PCB trace length between PESD5V0S4UD-Q and the protected connector?
For optimal ESD performance, the trace from the protected line to pins 1/3/4/6 should be ≤3 mm, and the common anode (pins 2 & 5) must connect directly to a solid ground plane via ≥2 vias within 2 mm. Longer traces increase inductance and degrade clamping effectiveness above 500 MHz.
Does PESD5V0S4UD-Q support bidirectional signal lines like USB D+ and D−?
No - it is a unidirectional array. For true bidirectional protection (e.g., USB 2.0), two devices are required per differential pair: one with cathodes on D+ and D− and anode grounded, and another with reversed polarity. Alternatively, use a dedicated bidirectional quad array such as PESD5V0X4U.
Can PESD5V0S4UD-Q be used on 3.3 V I/O lines despite its 5 V VRWM?
Yes - the 5 V reverse standoff voltage provides 1.7 V margin above 3.3 V nominal rails, ensuring negligible leakage (<200 nA) and no risk of premature conduction. Its 6.4–7.2 V breakdown range further guarantees safe operation under transient overvoltage conditions.
How does the dual common anode (pins 2 and 5) improve performance?
The dual anode terminals reduce total bond wire inductance by ~35% versus single-terminal equivalents, lowering clamping overshoot during sub-ns ESD events. Layout best practice requires connecting both pins 2 and 5 to the same low-inductance ground node using separate short traces or a common copper pour.
