Product details
Overview
PESD3V3S5UD-Q from Nexperia is a five-channel unidirectional ESD protection diode array in SOT457 (SC-74/TSOP6) package, designed to protect high-speed signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (20 A), with 3.3 V reverse standoff voltage, 12 V clamping at 20 A, and 215–300 pF capacitance - deployed in automotive infotainment data interfaces.
For engineers reviewing the PESD3V3S5UD-Q datasheet, PESD3V3S5UD-Q pinout, PESD3V3S5UD-Q application, or PESD3V3S5UD-Q equivalent, key selection criteria include clamping voltage under 20 A surge, sub-300 pF line capacitance for USB 2.0/MIPI compatibility, AEC-Q101 qualification, and common-anode five-cathode topology for compact multi-line protection.
Technical Context
This device implements a unidirectional five-diode array with a shared anode (Pin 2) and individual cathodes (Pins 1,3,4,5,6), enabling simultaneous protection of five independent signal paths referenced to a common ground return. Its architecture supports both positive- and negative-polarity transients relative to ground without polarity inversion.
Clamping behavior is defined by silicon PN junctions with typical breakdown at 5.6 V and low differential resistance (25 Ω), ensuring rapid voltage limiting during 8/20 µs surges. The 3.3 V VRWM allows integration on 3.3 V logic and high-speed serial buses while maintaining <300 nA leakage at rated standoff.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Ensures no conduction during normal 3.3 V signal operation; compatible with USB, MIPI D-PHY, and SDIO interfaces. |
| Clamping Voltage | 12 V at 20 A - Limits transient voltage to safe levels for downstream 3.3 V ICs during IEC 61000-4-5 surge events. |
| Diode Capacitance | 215–300 pF at 1 MHz - Low enough for ≤100 Mbps data rates; suitable for HDMI DDC, I²C, and UART lines. |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 - Meets automotive EMC requirements for exposed connectors and buttons. |
| Peak Pulse Power | 200 W - Sustains short-duration transients without thermal failure under standardized 8/20 µs waveform stress. |
| Junction Temperature Limit | 150 °C - Supports operation in under-hood or hot-plug industrial environments with derated power handling. |
Pinout & Package
SOT457 (SC-74/TSOP6) is a 6-pin, surface-mount plastic package measuring 3.1 × 1.7 × 1.1 mm with gull-wing leads and pin 1 index marker. It enables high-density placement near connectors on space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 (K1) | Protected signal line #1; connects to I/O trace before connector; clamps to common anode during overvoltage. |
| 2 | Common Anode (CA) | Shared return path to system ground; must be routed with low-inductance connection to minimize clamping overshoot. |
| 3 | Cathode 2 (K2) | Protected signal line #2; electrically isolated from K1 but shares same clamping threshold and thermal path. |
| 4 | Cathode 3 (K3) | Protected signal line #3; identical electrical characteristics to K1/K2; enables single-device protection of parallel bus lines. |
| 5 | Cathode 4 (K4) | Protected signal line #4; supports bidirectional data lines when paired with complementary devices or used in split-ground configurations. |
| 6 | Cathode 5 (K5) | Protected signal line #5; completes five-line coverage; layout symmetry aids balanced ESD current distribution across all cathodes. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard - enables deployment in ADAS camera links and infotainment USB ports without requalification. |
| Ultra-low leakage | 300 nA max at 3.3 V - Prevents signal integrity degradation and battery drain in always-on portable and telematics modules. |
| Low clamping voltage | 12 V at 20 A - Reduces risk of latch-up or oxide damage in 3.3 V interface ICs during surge events. |
| Five-line integration | Single SOT457 footprint replaces five discrete diodes - saves >4 mm² PCB area and eliminates routing mismatches between protection paths. |
| IEC 61000-4-2/4-5 compliance | Tested to full level 4 ESD and 20 A surge - satisfies CISPR 25 Class 5 and ISO 10605 requirements for vehicle subsystems. |

| SIM Card Socket Protection | Industrial HMI Touch Interface |
|
Use Scenario: Guarding SIM VCC, I/O, RST, CLK, and GND pins in ruggedized telematics units where card insertion generates repeated ESD stress. IC Role / Device Role / Timing Role: Direct replacement for discrete TVS arrays; cathodes routed to each SIM pin, CA connected to local ground island.

Equivalent & Alternatives
The following parts are listed as comparable options for similar five-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher VRWM (5.0 V); higher clamping (14.5 V at 20 A); 35 pF lower capacitance (180–265 pF). | Better suited for 5 V systems; less ideal for 3.3 V high-speed lines due to elevated clamping voltage. | Select when protecting 5 V UART or CAN FD lines where tighter capacitance tolerance is critical. |
| Vishay ESDE05C5B | Same 3.3 V VRWM; slightly higher leakage (500 nA); identical 12 V clamping; 200–280 pF capacitance. | Qualified to AEC-Q101 but lacks IEC 61000-4-5 surge rating documentation in public datasheet. | Prefer when ESD-only protection suffices and supply chain diversification is required. |
Compared with NUP4201MR6T1G and ESDE05C5B, PESD3V3S5UD-Q uniquely combines AEC-Q101 qualification, full IEC 61000-4-5 compliance, and optimized 3.3 V clamping margin - making it the most balanced choice for automotive-grade 3.3 V high-speed data line protection.

FAQ
What is the maximum operating temperature for PESD3V3S5UD-Q?
The device supports ambient temperatures from −65 °C to +150 °C and junction temperatures up to 150 °C. Derating of peak pulse power begins above 25 °C, with relative PPP dropping to ~80% at 100 °C per Figure 4 in the datasheet - confirming suitability for under-dash automotive locations.
Can PESD3V3S5UD-Q protect bidirectional signal lines like I²C?
Yes - though unidirectional in structure, its common-anode configuration allows protection of bidirectional lines when grounded at the CA pin. For I²C, it clamps both positive and negative transients on SDA/SCL relative to ground, provided the bus operates within 3.3 V VRWM and tolerates 12 V clamping during faults.
How does the 215–300 pF capacitance affect USB 2.0 signal integrity?
At 215–300 pF, total line capacitance remains within USB 2.0 Full-Speed (12 Mbps) and High-Speed (480 Mbps) specifications when combined with PCB trace and connector parasitics. Layout best practices - such as placing the device within 3 mm of the connector - keep effective rise-time degradation below 10%, preserving eye diagram margins.
Is PESD3V3S5UD-Q compatible with lead-free reflow soldering?
Yes - the SOT457 package is qualified for standard lead-free reflow profiles (J-STD-020). Peak temperature tolerance is 260 °C for 10 seconds, matching IPC/JEDEC J-STD-020D. Recommended footprint dimensions are provided in Figures 11 and 12 of the datasheet for optimal wetting and void control.
