Product details
Overview
PESD24VS1ULS from Nexperia is a unidirectional ESD protection diode in DFN1006BD-2 (SOD882BD) package, designed to protect one signal line against IEC 61000-4-2 contact discharge up to 23 kV and IEC 61000-4-5 surge pulses (IPP = 4.5 A). It features 24 V reverse standoff voltage, 60 V clamping voltage at 4.5 A, and ultra-low leakage (<1 nA), enabling robust transient suppression in space-constrained interfaces.
For engineers reviewing the PESD24VS1ULS datasheet, PESD24VS1ULS pinout, PESD24VS1ULS application, or PESD24VS1ULS equivalent, key selection criteria include clamping performance under 4.5 A surge, sub-50 pF capacitance at 1 MHz, AEC-Q101 qualification for automotive use, and side-wettable flanks for automated optical inspection of solder joints.
Technical Context
This device operates as a single-line unidirectional TVS diode with avalanche breakdown at 27 V (typical), clamping transients within 60 V at peak pulse current, and dynamic resistance of 1.6 Ω (typical) under TLP stress. Its low capacitance (23 pF typ.) ensures minimal signal distortion on high-speed lines.
The DFN1006BD-2 package integrates side-wettable flanks for solder-joint quality verification and supports reflow-compatible footprint per Figure 12. The cathode-marked terminal (pin 1) defines polarity-sensitive placement for positive-only signal protection relative to ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse voltage before leakage exceeds specification; sets operating margin for 24 V nominal signal rails. |
| VBR | 27 V (typ.) - Breakdown voltage at 5 mA; defines onset of avalanche conduction during overvoltage events. |
| VCL @ IPP = 4.5 A | 60 V - Clamping voltage during IEC 61000-4-5 8/20 µs surge; limits downstream IC stress during worst-case transients. |
| Cd @ 1 MHz | 23 pF (typ.) - Signal-line capacitance at zero bias; preserves integrity on USB 2.0, HDMI, or audio interfaces. |
| IRM @ VRWM | <1 nA - Reverse leakage current at rated standoff; avoids DC loading on high-impedance sensor or reference lines. |
| ESD Rating | 23 kV (IEC 61000-4-2 contact) - Withstands human-body-model discharges without degradation; validated over ten pulses. |
| AEC-Q101 | Qualified - Meets automotive-grade reliability requirements for temperature cycling, HTRB, and mechanical shock. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless ultra-small surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with 0.65 mm pitch and side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line; marking bar identifies this terminal; conducts during positive transients relative to ground. |
| 2 | Anode (A) | Connected to ground; completes current path during ESD/surge events; establishes unidirectional conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder fillets on both side edges-critical for high-reliability automotive PCB assembly. |
| Ultra-low capacitance | 23 pF typical at 1 MHz ensures <1% signal rise-time degradation on 480 Mbps USB 2.0 data lines. |
| Low clamping voltage | 60 V clamping at 4.5 A limits voltage overshoot to safe levels for 3.3 V/5 V interface ICs with 65 V absolute maximum ratings. |
| AEC-Q101 qualification | Validated for automotive underhood and infotainment applications requiring extended temperature operation (−55 °C to +150 °C). |
| Sub-1 nA leakage | Minimizes power loss and offset error in precision analog front-ends such as battery fuel gauges or sensor signal conditioning. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB peripherals against user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed adjacent to USB connector to shunt ESD energy to ground before reaching PHY IC. Use Value: 23 pF capacitance avoids signal integrity loss at 480 Mbps; 23 kV ESD rating exceeds IEC 61000-4-2 Level 4 requirement. |
Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin against insertion/removal transients in AV receivers and set-top boxes. IC Role / Device Role / Timing Role: Standoff diode clamping positive surges on 5 V-tolerant HPD line while maintaining DC logic level integrity. Use Value: 24 V VRWM matches HPD's 5 V logic swing with ample margin; 60 V clamping prevents latch-up in HDMI controller GPIOs. |
| Automotive Infotainment Displays | Industrial RS-485 Transceivers |
Use Scenario: Shielding LVDS or FPD-Link clock/data lanes in automotive center-stack displays from cable-discharge events. IC Role / Device Role / Timing Role: Single-line ESD clamp on each differential pair leg, mounted directly at display connector per AEC-Q101 layout guidelines. Use Value: AEC-Q101 qualification ensures operation across −40 °C to +105 °C ambient; side-wettable flanks support automated solder-joint verification. |
Use Scenario: Protecting RS-485 receiver inputs in factory automation gateways exposed to long-cable EFT and surge coupling. IC Role / Device Role / Timing Role: Unidirectional clamp on A/B bus lines referenced to local ground, limiting transient voltage to <60 V during 4.5 A surges. Use Value: 4.5 A IEC 61000-4-5 rating handles worst-case induced surges on 1 km industrial cabling; low leakage avoids false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105LT1G | Higher VRWM (30 V), higher VCL (70 V @ 4.5 A), larger SOT-523 package (1.6 mm × 0.8 mm) | Preferred where higher standoff voltage is needed for 28 V systems; less suitable for ultra-dense layouts | Select when system rail exceeds 24 V or board space allows larger footprint |
| Vishay VEML6030X01 | Not applicable - VEML6030X01 is an ambient light sensor, not an ESD diode; invalid substitution | N/A | Do not substitute; VEML6030X01 serves unrelated optical sensing function |
Compared with NUP4105LT1G, PESD24VS1ULS offers tighter 24 V standoff matching common 24 V industrial buses and 30% smaller footprint for miniaturized connectors, while maintaining identical 4.5 A surge rating and AEC-Q101 compliance.

FAQ
What is the maximum junction temperature for continuous operation?
The PESD24VS1ULS has a maximum junction temperature (Tj) of 150 °C per IEC 60134 limiting values. This rating applies under steady-state thermal conditions with proper PCB copper pour and thermal vias; derating is required above Tamb = 85 °C per Figure 4's PPP(Tj) curve.
Can this device protect bidirectional signal lines?
No. PESD24VS1ULS is strictly unidirectional: it clamps only positive transients on the cathode (pin 1) relative to anode (pin 2) ground. For bidirectional protection, two devices in series-opposed configuration or a dedicated bidirectional ESD diode such as PESD5V0S1BA must be used.
Is the 23 kV ESD rating tested per IEC 61000-4-2 contact or air discharge?
The 23 kV rating is specified for IEC 61000-4-2 contact discharge only, measured between pins 1 and 2. Air discharge testing is not characterized in the datasheet; design margins should assume contact discharge represents the most relevant real-world handling scenario.
How does side-wettable flank (SWF) construction aid manufacturing?
Side-wettable flanks expose solderable metal along both long edges of the DFN1006BD-2 package, enabling automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality-reducing field failures in automotive and medical assemblies where solder joint integrity is mission-critical.
