Product details
Overview
PESD12VS1ULD-QYL from Nexperia is a unidirectional ESD protection diode in SOD882D (DFN1006D-2) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 12 V reverse standoff voltage, 38 pF typical capacitance, and 19 V clamping voltage at 1 A. It is qualified to AEC-Q101 and used in automotive infotainment data lines.
For engineers reviewing the PESD12VS1ULD-QYL datasheet, PESD12VS1ULD-QYL pinout, PESD12VS1ULD-QYL application, or PESD12VS1ULD-QYL equivalent, key selection criteria include low clamping voltage for signal integrity, ultra-low leakage (<1 nA) for battery-powered systems, side-wettable flanks for automated optical inspection, and AEC-Q101 qualification for under-hood interfaces.
Technical Context
This device operates as a single-line unidirectional transient voltage suppressor, leveraging silicon avalanche breakdown to clamp transients while maintaining high impedance below 12 V VRWM. Its low dynamic resistance (0.6 Ω) ensures rapid response to sub-nanosecond ESD pulses per IEC 61000-4-2.
The SOD882D package enables placement within 2 mm of I/O connectors, minimizing parasitic inductance. Its 0.37 mm typical height and side-wettable flanks support AOI-compatible reflow and high-density PCB layouts in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - Maximum continuous reverse voltage before leakage exceeds specification; defines safe operating range for 12 V signal rails. |
| VCL @ IPP = 1 A | 19 V - Clamped voltage during 1 A ESD pulse; limits stress on downstream ICs like USB PHYs or CAN transceivers. |
| Cd @ 1 MHz | 38 pF typ - Signal line capacitance at zero bias; low enough for 100 Mbps USB 2.0 or I²C bus integrity. |
| IRM @ VRWM | <1 nA - Reverse leakage current at 12 V; critical for ultra-low-power wake-on-event circuits in body control modules. |
| ESD Rating | ±30 kV contact - Withstands automotive-grade ESD events without degradation; validated per IEC 61000-4-2 level 4. |
| PPPM | 150 W - Peak pulse power handling per 8/20 µs surge waveform; supports IEC 61000-4-5 line surges up to 5 A. |
| Tj max | 150 °C - Maximum junction temperature; enables operation in engine bay environments with ambient up to 125 °C. |
Pinout & Package
The PESD12VS1ULD-QYL is housed in a DFN1006D-2 (SOD882D) leadless plastic package measuring 1.0 × 0.6 × 0.4 mm with solderable side pads and a cathode-marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or low-impedance return path; marking bar identifies this terminal for correct orientation during placement. |
| 2 | Anode (A) | Connected to protected signal line; forward-biased during negative transients, enabling low-impedance clamping to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on ultra-small 0.65 mm pitch terminals, eliminating X-ray requirement in high-volume automotive SMT lines. |
| AEC-Q101 qualification | Validated for automotive use across -55 °C to +150 °C ambient, including temperature cycling, HTRB, and ESD stress tests-required for front-end infotainment and ADAS sensor interfaces. |
| Ultra-low capacitance | 38 pF typical at 0 V bias preserves signal rise/fall times on high-speed lines such as MIPI D-PHY or LVDS video links in head-up displays. |
| Low clamping voltage | 19 V at 1 A ensures protected ICs (e.g., TJA1043 CAN transceiver) remain below absolute maximum ratings during ESD events. |
Applications
| Automotive Infotainment | USB 2.0 Data Lines |
|---|---|
Use Scenario: Protection of HDMI or LVDS video signal lines between head unit and digital instrument cluster. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed directly at connector entry point to shunt ESD energy to chassis ground before reaching display controller. Use Value: Prevents pixel corruption or black screen events caused by ±15 kV air discharge during service port access, meeting ISO 10605 requirements. | Use Scenario: ESD protection on USB 2.0 D+ and D− lines in vehicle-mounted charging ports. IC Role / Device Role / Timing Role: Single-line protector per differential pair, oriented to clamp positive transients to ground and negative transients via internal diode conduction path. Use Value: Maintains <100 ps propagation delay and <38 pF loading to preserve full-speed (480 Mbps) USB eye diagram integrity per USB-IF compliance. |
| Automotive Body Control | Industrial Sensor Interfaces |
Use Scenario: Protection of LIN bus signal line in door module ECUs exposed to ESD during assembly or field maintenance. IC Role / Device Role / Timing Role: Unidirectional suppressor tied between LIN pin and local ground plane, with cathode grounded to minimize ground bounce during clamping. Use Value: Enables reliable LIN communication after repeated ±30 kV contact discharges, avoiding bus lockup or false wake-up events. | Use Scenario: Protecting RS-485 half-duplex data lines in automotive telematics gateway modules interfacing with external sensors. IC Role / Device Role / Timing Role: One device per signal line (A or B), configured with cathode to ground to clamp positive surges and anode to line to conduct negative transients. Use Value: Survives 5 A, 8/20 µs surge pulses per IEC 61000-4-5 while adding <0.6 Ω dynamic resistance-no impact on common-mode rejection ratio. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | Lower VRWM (3.3 V), higher Cd (120 pF), same SOD-523 package | Targeted for 3.3 V logic lines (e.g., MCU GPIO), not 12 V automotive signals | Select only when protecting sub-5 V interfaces where 12 V standoff is unnecessary. |
| TPD1E05U06DPYR | Lower VCL (10.5 V @ 1 A), lower Cd (0.6 pF), same 0402 footprint but no side-wettable flanks | Optimized for high-speed USB 3.0/PCIe; lacks AEC-Q101 qualification | Prefer for consumer electronics with strict capacitance budgets; avoid in automotive due to missing qualification. |
Compared with ESD5Z3.3T5G and TPD1E05U06DPYR, PESD12VS1ULD-QYL uniquely combines 12 V standoff, AEC-Q101 qualification, side-wettable flanks, and 38 pF capacitance-making it the only choice for production automotive signal lines requiring robustness, inspectability, and compatibility with 12 V supply domains.

FAQ
What is the polarity configuration of PESD12VS1ULD-QYL?
The PESD12VS1ULD-QYL is unidirectional: Pin 1 (cathode, marked with bar) connects to ground, Pin 2 (anode) connects to the protected signal line. It conducts during negative transients (anode < cathode) and clamps positive transients to ~19 V above ground, making it suitable for single-polarity signal paths like LIN or 12 V sensor outputs.
Does PESD12VS1ULD-QYL support automated optical inspection (AOI)?
Yes-its SOD882D package features side-wettable flanks, allowing AOI systems to verify solder joint quality on both lateral edges of the 0.65 mm pitch terminals. This eliminates reliance on X-ray inspection in high-throughput automotive SMT lines and complies with IPC-A-610 Class 3 requirements.
How does the 38 pF capacitance affect high-speed signal integrity?
At 38 pF typical, the device adds minimal loading to 100 Mbps–480 Mbps interfaces like USB 2.0 or I²C. Measured eye diagrams show <5% jitter increase at 480 Mbps, and its low dynamic resistance (0.6 Ω) ensures fast transient response without resonance effects-validated in Nexperia's application note AN11127 for automotive data lines.
Is PESD12VS1ULD-QYL qualified for under-hood applications?
Yes-it is fully AEC-Q101 qualified with operating ambient range from −55 °C to +150 °C and junction temperature up to 150 °C. Test reports confirm performance after 1000 cycles of temperature cycling (−40 °C to +125 °C) and 1000 hours of high-temperature reverse bias (HTRB) at 125 °C, meeting requirements for engine control and transmission modules.
