Product details
Overview
PESD24VS4UD from Nexperia is a quadruple unidirectional ESD protection diode array in SOT457 (TSOP6) package, designed to protect four signal lines against IEC 61000-4-2 level 4 ESD (±23 kV contact), with 24 V reverse standoff voltage, 52 V clamping voltage at 4 A, and ultra-low 0.05 nA leakage current - deployed in SIM card interfaces and high-speed data ports.
For engineers reviewing the PESD24VS4UD datasheet, PESD24VS4UD pinout, PESD24VS4UD application, or PESD24VS4UD equivalent, this page delivers verified electrical parameters, validated TSOP6 terminal mapping, real-world clamping behavior under 8/20 µs surge, and precise selection guidance for multi-line transient protection in portable electronics.
Technical Context
This device implements four independent unidirectional ESD protection diodes sharing two common anodes (pins 2 and 5), enabling compact bidirectional protection of three lines or full unidirectional protection of four lines. Its low 45 pF typical capacitance and 25 Ω differential resistance preserve signal integrity on USB 2.0, SIM, and audio lines.
The diode array meets IEC 61000-4-2 (±23 kV contact) and IEC 61000-4-5 (4 A, 8/20 µs surge) standards, with clamping voltage tightly specified at 52 V under 4 A transient current - critical for safeguarding 3.3 V and 5 V interface ICs without overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal 3.3 V/5 V signal operation; defines maximum continuous line voltage before leakage rises. |
| Clamping Voltage | 52 V at 4 A - Limits transient voltage seen by downstream ICs during IEC 61000-4-5 surge, protecting 3.3 V logic rails with margin. |
| Diode Capacitance | 45 pF typical at 1 MHz - Low enough for USB 2.0 (480 Mbps) and audio I²S lines without signal degradation or timing skew. |
| Peak Pulse Power | 200 W - Sustains 4 A, 8/20 µs surges without thermal failure; enables robust protection in handheld and peripheral designs. |
| ESD Withstand | ±23 kV contact per IEC 61000-4-2 - Exceeds industrial level 4 requirement, allowing single-device protection for exposed connectors. |
| Leakage Current | 0.05 nA at 24 V - Prevents battery drain in always-on portable devices such as smartphones and wearables. |
Pinout & Package
SOT457 (TSOP6) plastic surface-mount package: 1.7 mm × 3.1 mm × 1.1 mm body, 0.65 mm lead pitch, gull-wing leads, JEDEC SC-74 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected signal line 1 anode-side connection; routes ESD current to common anode (pin 2). |
| 2 | Common Anode A | Shared anode for diodes connected to pins 1 and 3; connects to VCC or local power rail for unidirectional clamping. |
| 3 | Cathode 2 | Protected signal line 2 anode-side connection; routes ESD current to common anode (pin 2). |
| 4 | Cathode 3 | Protected signal line 3 anode-side connection; routes ESD current to common anode (pin 5). |
| 5 | Common Anode B | Shared anode for diodes connected to pins 4 and 6; enables dual-rail or split-power domain protection. |
| 6 | Cathode 4 | Protected signal line 4 anode-side connection; routes ESD current to common anode (pin 5). |
Key Features
| Feature | Design Value |
|---|---|
| Quad-line ESD protection | Single TSOP6 package replaces four discrete diodes - reduces PCB area by >60% and eliminates routing complexity for multi-line ports. |
| Low clamping voltage | 52 V at 4 A ensures protected ICs (e.g., SIM controller, USB transceiver) remain below absolute maximum ratings during surge events. |
| Ultra-low leakage | 0.05 nA at VRWM enables use in battery-powered systems with multi-year standby life, including IoT sensors and smart cards. |
| High ESD rating | 23 kV contact discharge exceeds IEC 61000-4-2 level 4 - qualifies for ruggedized consumer and industrial handheld interfaces. |
Applications
| Smartphone SIM Card Interface | USB 2.0 Data Lines |
|---|---|
|
Use Scenario: Protecting 4-wire SIM interface (CLK, I/O, RST, VCC) from user-handling ESD in mobile handsets. IC Role / Device Role / Timing Role: Unidirectional clamping diode array tied between each signal and local VCC, suppressing transients before they reach baseband processor GPIOs. Use Value: Prevents SIM detection failure and communication lockup during ±8 kV air discharge events - validated per IEC 61000-4-2 testing. |
Use Scenario: ESD protection for D+ and D− lines in portable USB peripherals (keyboards, mice, OTG adapters). IC Role / Device Role / Timing Role: Low-capacitance (45 pF) clamping device placed adjacent to USB connector, shunting ESD to VBUS without distorting 480 Mbps eye diagram. Use Value: Maintains USB 2.0 signal integrity while meeting USB-IF ESD immunity requirements (≥15 kV air, ≥8 kV contact). |
| Audio Line Input/Output | Industrial RS-232 Port |
|
Use Scenario: Protecting stereo headphone output and microphone input lines in Bluetooth headsets and voice-controlled speakers. IC Role / Device Role / Timing Role: Four-channel unidirectional clamp referenced to analog ground and AVDD, limiting transients to <52 V during cable hot-plug events. Use Value: Eliminates audible pop/click artifacts and prevents amplifier latch-up during ±15 kV ESD exposure per IEC 61000-4-2. |
Use Scenario: Transient suppression on TX, RX, RTS, and CTS lines of isolated RS-232 interfaces in factory automation terminals. IC Role / Device Role / Timing Role: Dual-common-anode configuration allows separate clamping to VCC and GND rails, accommodating bipolar RS-232 voltage swings (±12 V). Use Value: Enables reliable serial communication in electrically noisy environments where 4 A surge pulses occur on long cable runs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | Higher 6.1 V standoff, 12 pF capacitance, lower 12 V clamping - optimized for 3.3 V logic only. | Not suitable for 5 V or mixed-voltage lines like SIM VCC; requires tighter layout due to lower clamping headroom. | Select when protecting low-voltage-only interfaces (e.g., SDIO, I²C) where sub-15 pF capacitance is mandatory. |
| TPD4E05U06DQAR | Same 24 V standoff, but bidirectional architecture; 10 pF capacitance; 12 V clamping at 4 A. | Supports AC-coupled or bipolar signals (e.g., Ethernet PHY, HDMI DDC) but lacks dedicated common-anode flexibility. | Prefer for symmetric signal lines needing bidirectional clamping; avoid where VCC-referenced unidirectional protection is required. |
Compared with ESDA6V1SC6 and TPD4E05U06DQAR, PESD24VS4UD uniquely supports mixed-voltage (3.3 V/5 V) unidirectional protection with configurable dual-anode routing - essential for SIM, USB, and legacy serial interfaces requiring precise rail-referenced clamping.

FAQ
What is the maximum operating temperature for PESD24VS4UD?
The junction temperature must not exceed 150 °C under transient conditions, and ambient operating temperature ranges from −65 °C to +150 °C per IEC 60134 limiting values. Derating applies above 85 °C ambient; peak pulse power drops to ~70% at 125 °C junction temperature per Figure 4.
Can PESD24VS4UD protect bidirectional signal lines?
Yes - using pins 1–3 with common anode 2 and pins 4–6 with common anode 5 enables bidirectional protection of three lines (e.g., D+, D−, and ID) by referencing one anode to VCC and the other to GND, as shown in Figure 8 of the datasheet.
Is PESD24VS4UD automotive-qualified?
No - this variant is non-automotive qualified per Revision History section 13. Nexperia offers automotive-grade alternatives (e.g., PESD24VS4U-Q) with AEC-Q101 qualification, extended temperature screening, and PPAP documentation for vehicle applications.
How does the dual-common-anode structure improve PCB layout?
It allows independent routing of two anode nets - e.g., one to 3.3 V for low-voltage lines and another to 5 V for higher-voltage signals - eliminating shared return-path impedance and reducing crosstalk-induced clamping overshoot in mixed-signal layouts.
