Product details
Overview
PESD15VS1ULD-Q from Nexperia is a unidirectional ESD protection diode in SOD882D (DFN1006D-2) package, designed to protect single signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact/air) and IEC 61000-4-5 surge (5 A, 8/20 µs). It delivers low clamping voltage (23 V at 1 A), ultra-low leakage (1 nA at 15 V), and 32 pF typical capacitance - ideal for high-speed USB 2.0, HDMI, or automotive infotainment data lines.
For engineers reviewing the PESD15VS1ULD-Q datasheet, PESD15VS1ULD-Q pinout, PESD15VS1ULD-Q application, or PESD15VS1ULD-Q equivalent, key selection criteria include reverse standoff voltage (15 V), clamping performance under 5 A surge, AEC-Q101 qualification, side-wettable flanks for solder inspection, and compatibility with space-constrained PCB layouts requiring <0.4 mm height.
Technical Context
This device operates as a single-line unidirectional transient voltage suppressor, leveraging silicon avalanche breakdown to clamp transients while maintaining low dynamic resistance (0.6 Ω) during pulse events. Its operation is defined by a 15 V reverse standoff voltage and 17.6–18.4 V breakdown threshold at 5 mA.
The diode exhibits asymmetric conduction: forward-biased only when the anode exceeds cathode by ≥17.6 V, enabling robust protection of positive-polarity signal lines without interfering with normal DC bias. Its 32–70 pF capacitance is optimized for signal integrity on interfaces up to 480 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - maximum continuous DC or RMS signal voltage the line can carry without triggering conduction |
| Clamping Voltage (1 A) | 23 V - peak voltage seen across protected line during 1 A ESD event, limiting stress on downstream ICs |
| Clamping Voltage (5 A) | 40 V - maximum voltage imposed during full-rated 5 A surge, defining worst-case protection margin |
| Diode Capacitance | 32 pF (typ) - ensures minimal signal distortion on USB 2.0 or audio lines operating below 100 MHz |
| Leakage Current | 1 nA at 15 V - negligible DC loading on high-impedance sensor or reference lines |
| ESD Rating | ±30 kV per IEC 61000-4-2 - meets automotive and industrial immunity requirements for connector-level discharge |
| Peak Pulse Power | 150 W - sustains 5 A, 8/20 µs surges without degradation, validated per IEC 61000-4-5 |
Pinout & Package
Package: DFN1006D-2 (SOD882D), leadless ultra-small surface-mount plastic package measuring 1.0 × 0.6 × 0.4 mm with side-wettable flanks for automated optical solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to system ground or low-impedance return path; marked by visible bar on top surface |
| 2 | Anode | Connected to signal line requiring protection; conducts transient current to ground when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including infotainment and ADAS sensor interfaces |
| Side-wettable flanks | Enables automated X-ray or AOI inspection of solder joints without cross-sectioning |
| Ultra-low profile (0.37 mm typ) | Fits beneath tight mechanical shields and enables double-sided PCB assembly |
| Low dynamic resistance (0.6 Ω) | Minimizes voltage overshoot during fast-rising ESD pulses (<1 ns rise time) |
| 1 nA reverse leakage | Preserves battery life in always-on portable electronics with high-impedance monitoring circuits |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD during cable insertion/removal in automotive head units. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between connector and USB transceiver, referenced to chassis ground. Use Value: 32 pF capacitance avoids signal integrity loss at 480 Mbps; 15 V VRWM matches USB common-mode range. |
Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) line from user-induced ESD in home theater receivers. IC Role / Device Role / Timing Role: Single-line protector between HDMI connector and microcontroller GPIO, with cathode grounded. Use Value: 1 nA leakage prevents false HPD assertion; 23 V clamping protects 3.3 V GPIO inputs during ±8 kV contact discharge. |
| Automotive Infotainment Audio | Portable Medical Sensor Interface |
|
Use Scenario: Shielding analog audio input lines (e.g., AUX-in) in vehicle entertainment systems from dashboard ESD events. IC Role / Device Role / Timing Role: Signal-line protector on unidirectional analog path, positioned within 2 mm of connector per layout guidelines. Use Value: 40 V clamping at 5 A ensures survival during ISO 10605 330 Ω/150 pF discharge; AEC-Q101 certification validates reliability. |
Use Scenario: Protecting ECG electrode input lines in handheld patient monitors from operator-handling ESD. IC Role / Device Role / Timing Role: First-stage transient suppressor on high-impedance biopotential trace, before instrumentation amplifier. Use Value: 1 nA leakage avoids baseline drift; 15 V VRWM accommodates ±10 V electrode offset ranges without forward conduction. |
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 capacitance (110 pF), lower clamping (18 V @ 1 A), same 15 V VRWM and SOD-923 package | Better for low-speed logic but unsuitable for USB 2.0 due to excessive capacitance | Select when lower clamping voltage outweighs bandwidth constraints and board space permits larger footprint |
| Vishay VEML6030X01 | Not applicable - this is an ambient light sensor, not an ESD diode; excluded from valid alternatives | N/A | Not a functional alternative; confirmed invalid via Vishay product database and datasheet review |
Compared with PESD15VS1ULD-Q, NUP4105LT1G offers tighter clamping but sacrifices high-speed signal integrity, while no verified unidirectional 15 V ESD diode in SOD882D with matching AEC-Q101, 32 pF, and side-wettable flanks exists as a direct alternative.

FAQ
What is the meaning of the marking code '0110' on PESD15VS1ULD-Q?
The '0110' marking is a binary code etched on the top surface indicating the device variant and manufacturing lot; it corresponds to the PESD15VS1ULD-Q type per Nexperia's SOD882D marking standard (Fig. 1), with the cathode bar adjacent to pin 1. This code is used for traceability and does not encode electrical parameters.
Can PESD15VS1ULD-Q protect bidirectional signal lines like RS-485?
No - PESD15VS1ULD-Q is unidirectional and only clamps positive transients relative to ground. For bidirectional lines, two devices must be used in series opposition or a dedicated bidirectional diode such as PESD5V0S1BA must be selected to handle both polarities.
Is the SOD882D package compatible with standard reflow profiles for lead-free soldering?
Yes - the device is qualified for JEDEC J-STD-020D Level 1 moisture sensitivity and supports standard Pb-free reflow profiles with peak temperature ≤260 °C. The recommended footprint (Fig. 11) uses 0.7 mm wide side pads with 0.65 mm pitch for reliable wetting and void-free joints.
How does the 0.6 Ω dynamic resistance impact ESD protection performance?
A dynamic resistance of 0.6 Ω limits voltage overshoot during sub-nanosecond ESD rise times, ensuring clamping remains effective even for fast transients. This value was measured using TLP (Transmission Line Pulse) testing per ANSI/ESD STM5.5.1-2008, directly correlating to real-world IEC 61000-4-2 performance.
