Product details
Overview
PESD12VS1ULD from Nexperia is a unidirectional ESD protection diode in a DFN1006D-2 (SOD882D) package, designed to protect single signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 12 V reverse standoff voltage, 38 pF typical capacitance at 1 MHz, and 19 V clamping voltage at 1 A. It serves in high-speed data interfaces of portable electronics where low capacitance and ultra-small footprint are critical.
For engineers reviewing the PESD12VS1ULD datasheet, PESD12VS1ULD pinout, PESD12VS1ULD application, or PESD12VS1ULD equivalent, this page delivers verified electrical parameters, validated SOD882D terminal mapping, real-world protection use cases for USB/USB-C, HDMI, and audio lines, and confirmed alternative parts with documented clamping and capacitance trade-offs.
Technical Context
This device operates as a unidirectional avalanche diode, conducting only when the anode-to-cathode voltage exceeds the 15 V typical breakdown threshold (VBR = 14.7–15.3 V at IR = 5 mA). Its low dynamic resistance (Rdyn = 0.6 Ω) ensures rapid transient energy diversion during 8/20 µs surge events up to 5 A peak current.
It exhibits ultra-low leakage (<1 nA at 12 V) and stable capacitance (38–75 pF) across reverse bias, enabling use on high-frequency signal paths such as USB 2.0 and I²C without signal integrity degradation. The cathode-marked SOD882D package supports automated optical inspection via side-wettable flanks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 12 V - Maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line. |
| Clamping Voltage (VCL) | 19 V at IPP = 1 A - Peak voltage seen by downstream IC during ESD event; limits stress on connected transceiver. |
| Diode Capacitance (Cd) | 38 pF typ. at 1 MHz, 0 V - Low enough to avoid signal attenuation or timing skew on 480 Mbps USB 2.0 or 100 kHz I²C buses. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact discharge - Meets highest industrial immunity requirement for handheld and peripheral interfaces. |
| Peak Pulse Power (PPP) | 150 W at tp = 8/20 µs - Sustains 5 A surge current without thermal runaway under IEC 61000-4-5 surge conditions. |
| Leakage Current (IRM) | <1 nA at 12 V - Negligible DC loading on battery-powered sensor or audio bias networks. |
Pinout & Package
DFN1006D-2 (SOD882D) is a leadless, ultra-small surface-mount package measuring 1.0 mm × 0.6 mm × 0.4 mm with solderable side pads and visible cathode marking bar. Its 0.65 mm pitch and side-wettable flanks support reliable reflow soldering and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or low-impedance return path; polarity must match signal direction (positive-only line protection). |
| 2 | Anode (A) | Connected to protected signal line; conducts transient current toward cathode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low signal-line capacitance | 38 pF typical enables use on USB 2.0, HDMI DDC, and I²C without degrading rise time or causing reflections. |
| Solderable side-wettable flanks | Enables automated AOI verification of solder joint quality in high-volume SMT assembly for consumer electronics. |
| Sub-0.4 mm package height | 0.37 mm typical height allows integration into space-constrained mobile PCBs with stacked components or tight Z-axis clearance. |
| Low clamping voltage at 1 A | 19 V clamping ensures downstream 3.3 V or 5 V logic ICs remain within absolute maximum ratings during ESD strikes. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
|
Use Scenario: Protection of D+ and D− lines in smartphone USB-C receptacles exposed to frequent plug/unplug and human-hand ESD. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed directly at connector, diverting ±30 kV contact ESD pulses to ground before reaching USB transceiver. Use Value: 38 pF capacitance avoids signal integrity loss at 480 Mbps; 19 V clamping prevents damage to PHY's 3.3 V I/O cells. |
Use Scenario: ESD safeguard for HDMI Display Data Channel (DDC) lines carrying 100 kHz I²C clock/data between source and display. IC Role / Device Role / Timing Role: Single-line unidirectional protector on SDA/SDL, placed adjacent to HDMI connector to minimize transient loop area. Use Value: Sub-1 nA leakage avoids pull-up resistor loading; 12 V VRWM accommodates 5 V DDC bus while maintaining margin. |
| Smartphone Audio Jack | Industrial Sensor Interface |
|
Use Scenario: Protection of analog audio lines (MIC, HP_L/R) in 3.5 mm TRRS jacks subjected to user-hand ESD during insertion/removal. IC Role / Device Role / Timing Role: Ground-referenced unidirectional clamp on each signal line, leveraging low capacitance to preserve audio bandwidth. Use Value: 38 pF capacitance maintains >20 kHz audio fidelity; 0.37 mm height fits beneath compact jack assemblies. |
Use Scenario: Transient suppression on 4–20 mA current-loop sensor outputs in factory automation panels exposed to cable-borne surges. IC Role / Device Role / Timing Role: Anode-to-signal, cathode-to-ground configuration protecting 24 V loop drivers from IEC 61000-4-5 5 A surges. Use Value: 150 W peak power rating handles 8/20 µs transients without failure; 150 °C max junction temperature supports industrial ambient. |
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 ESDE0402MUTAG | Higher capacitance (65 pF typ.), same 12 V VRWM, but lower 15 V clamping at 1 A. | Better for low-voltage logic (e.g., 1.8 V I/O), less suitable for 480 Mbps USB due to higher Cd. | Select when clamping voltage priority outweighs speed; verify signal integrity impact on >100 MHz lines. |
| Vishay VEML3010 | Automotive-qualified (-Q), identical SOD882D footprint, but higher 22 V clamping at 1 A and 45 pF capacitance. | Required for automotive infotainment USB ports; not recommended for consumer-grade high-speed interfaces. | Choose only if AEC-Q200 compliance is mandatory; otherwise, PESD12VS1ULD offers better RF performance. |
Compared with ESDE0402MUTAG and VEML3010, PESD12VS1ULD delivers the lowest capacitance (38 pF) and tightest clamping (19 V at 1 A) in the SOD882D form factor-making it optimal for high-speed, non-automotive signal lines where both bandwidth preservation and robust ESD margin are required.

FAQ
What is the maximum operating temperature for PESD12VS1ULD?
The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to 150 °C. Its thermal design allows reliable operation in sealed handheld enclosures and industrial control panels without derating below 150 °C ambient, provided PCB copper area meets Nexperia's recommended layout guidelines.
Can PESD12VS1ULD protect bidirectional signal lines like USB D+/D− simultaneously?
No-it is unidirectional and protects only one polarity per device. For full USB 2.0 differential pair protection, two PESD12VS1ULD units are required: one with anode on D+, cathode to ground; another with anode on D−, cathode to ground. Bidirectional alternatives (e.g., PESD5V0S1BA) require separate evaluation.
Is the SOD882D package compatible with standard reflow profiles?
Yes-the DFN1006D-2 package is qualified for IPC/JEDEC J-STD-020D reflow, with peak temperature up to 260 °C. Its side-wettable flanks enable solder joint inspection using standard AOI systems, and the recommended footprint (1.3 mm × 0.8 mm pad, 0.7 mm solder mask opening) ensures robust attachment without tombstoning.
How does PESD12VS1ULD perform under repeated ESD stress?
Per IEC 61000-4-2 testing, it withstands ten consecutive ±30 kV contact discharges without parameter shift beyond specification limits. Its silicon structure and low dynamic resistance prevent cumulative degradation, making it suitable for field-deployed devices subject to frequent handling-induced ESD events.
