Product details
Overview
PESD15VS1ULS from Nexperia is a unidirectional ESD protection diode in DFN1006BD-2 (SOD882BD) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It features 15 V reverse standoff voltage, 23 V clamping at 1 A, 32 pF typical capacitance, and 1 nA leakage - ideal for high-speed USB 2.0 or HDMI data lines in portable electronics.
For engineers reviewing the PESD15VS1ULS datasheet, PESD15VS1ULS pinout, PESD15VS1ULS application, or PESD15VS1ULS equivalent, key selection criteria include clamping voltage under 5 A surge, sub-70 pF capacitance for signal integrity, side-wettable flanks for automated optical inspection (AOI), and AEC-Q101 qualification for automotive infotainment interfaces.
Technical Context
This unidirectional TVS diode operates as a single-line transient suppressor with cathode-grounded configuration. Its low dynamic resistance (0.6 Ω typ.) ensures rapid voltage clamping during fast-rising ESD events (tr ≤ 1 ns), while its ultra-low leakage (<1 nA at 15 V) prevents DC loading on sensitive analog or high-impedance signal paths.
The device leverages silicon avalanche breakdown at 18 V (typ.) to initiate conduction before system-level damage occurs. Its DFN1006BD-2 footprint enables placement within 2 mm of I/O connectors, minimizing inductive loop area critical for suppressing >1 GHz ESD energy per IEC 61000-4-2 waveform compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous operating voltage without leakage increase; defines upper limit for protected line DC bias. |
| Clamping Voltage (IPP = 5 A) | 40 V - Peak voltage seen by downstream IC during IEC 61000-4-5 surge; must stay below IC absolute max rating. |
| Diode Capacitance | 32 pF (typ.) - Measured at 1 MHz, 0 V; low enough for <100 Mbps digital interfaces without signal rise-time degradation. |
| ESD Withstand | ±30 kV (IEC 61000-4-2 contact) - Verified survival after 10 pulses; meets industrial and automotive EMC immunity requirements. |
| Leakage Current | 1 nA (typ. at VRWM) - Negligible loading on high-impedance sensor or reference lines; avoids offset drift in precision circuits. |
| Package | DFN1006BD-2 (SOD882BD) - 1.0 × 0.6 × 0.47 mm body with side-wettable flanks for reliable solder-joint AOI and reflow yield. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and marking bar indicating cathode (Pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode | Connected to ground or low-impedance return path; carries surge current during positive transients on protected line. |
| 2 | Anode | Connected to signal line requiring protection; reverse-biased during normal operation; conducts only during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress - suitable for infotainment and ADAS sensor interfaces. |
| Side-wettable flanks | Enables automated optical inspection of solder joints on bottom terminals - critical for high-volume SMT manufacturing yield control. |
| Low clamping voltage (23 V @ 1 A) | Minimizes voltage overshoot during initial ESD strike, reducing risk of latch-up or gate oxide damage in connected ICs. |
| Ultra-low capacitance variation | Capacitance remains stable (32–70 pF) across 0–15 V reverse bias - preserves signal integrity in AC-coupled high-speed links. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against user-hand ESD events. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed between connector and USB transceiver IC. Use Value: 32 pF capacitance avoids signal integrity loss at 480 Mbps; 15 V VRWM matches USB 2.0 common-mode range. |
Use Scenario: Shielding TMDS clock and data pairs in HDMI source devices (e.g., set-top boxes) from cable-discharge events. IC Role / Device Role / Timing Role: Line-level ESD clamp referenced to chassis ground, installed adjacent to HDMI receptacle. Use Value: 40 V clamping at 5 A ensures downstream retimer ICs remain below 50 V absolute maximum rating during surge. |
| Automotive Infotainment | Smartphone Audio Jacks |
Use Scenario: Safeguarding I²S or SPDIF audio interfaces in head units exposed to ESD via front-panel controls or auxiliary inputs. IC Role / Device Role / Timing Role: Single-line unidirectional protector on bidirectional audio data lines referenced to vehicle ground. Use Value: AEC-Q101 qualification guarantees operation from −40 °C to +125 °C ambient; 1 nA leakage prevents audio DC offset. |
Use Scenario: Protecting 3.5 mm TRRS microphone and headset detection lines in smartphones against pocket discharge. IC Role / Device Role / Timing Role: Ground-referenced ESD clamp on MIC_BIAS and HP_DETECT lines with minimal board space. Use Value: 1.0 × 0.6 mm footprint fits tight routing near jack; side-wettable flanks ensure solder joint reliability in thin PCB stacks. |
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 typ.), higher clamping (48 V @ 5 A), same 15 V VRWM and SOD-923 package. | Less suitable for >480 Mbps interfaces due to capacitance; better for lower-speed automotive LIN bus. | Select when board layout constraints favor SOD-923 over DFN1006BD-2 and signal bandwidth <10 MHz. |
| Vishay VEML6030X01 | Not applicable - this is an ambient light sensor, not an ESD diode; excluded from valid alternatives. | N/A | Not a functional alternative; discard from comparison. |
Compared with PESD15VS1ULS, NUP4105LT1G trades higher capacitance and clamping for broader package availability and legacy design reuse, while no verified second alternative meets the combined requirements of 32 pF capacitance, 40 V clamping at 5 A, and AEC-Q101 qualification in DFN1006BD-2.

FAQ
Is PESD15VS1ULS suitable for bidirectional signal lines?
No. PESD15VS1ULS is unidirectional and protects only signals referenced to ground with positive polarity. For bidirectional lines like USB D+/D− differential pairs, use a symmetric dual-diode array such as PESD5V0S1BA or equivalent.
What is the significance of side-wettable flanks in DFN1006BD-2?
Side-wettable flanks expose solderable metal on the package edges, enabling automated optical inspection (AOI) of solder joint quality on bottom-terminated components - essential for zero-defect manufacturing in high-density portable electronics assembly.
How does the 1 nA leakage current impact high-impedance sensor circuits?
At 1 nA typical leakage, the diode introduces negligible error in circuits with ≥1 MΩ source impedance - for example, adding <1 µV offset in a 1 V full-scale 12-bit ADC input stage, well within LSB resolution limits.
Can PESD15VS1ULS replace PESD5V0S1BA in USB 2.0 designs?
No. PESD5V0S1BA is bidirectional with 5 V standoff and lower clamping (~12 V), optimized for 5 V-tolerant USB transceivers. PESD15VS1ULS has 15 V standoff and unidirectional behavior - mismatched for standard USB 2.0 voltage rails and polarity handling.
