Product details
Overview
PESD8V0S1ULD-Q from Nexperia is a unidirectional ESD protection diode in SOD882D (DFN1006D-2) package, designed to protect one signal line against IEC 61000-4-2 contact discharge up to 30 kV and IEC 61000-4-5 surges (8/20 µs, IPP = 13 A). It features 8 V reverse standoff voltage, 18.5 V clamping voltage at 13 A, and 70 pF typical capacitance at 1 MHz - optimized for high-speed automotive interface lines including USB 2.0 and CAN FD.
For engineers reviewing the PESD8V0S1ULD-Q datasheet, PESD8V0S1ULD-Q pinout, PESD8V0S1ULD-Q application, or PESD8V0S1ULD-Q equivalent, key selection criteria include unidirectional clamping behavior, AEC-Q101 qualification, ultra-low 0.4 Ω dynamic resistance, side-wettable flanks for solder inspection, and compatibility with 0.65 mm pitch PCB layouts.
Technical Context
This device operates as a single-line unidirectional TVS diode with avalanche breakdown at 9.1 V (typical), enabling fast response (<1 ns) to ESD transients while maintaining low leakage (<500 nA at 8 V). Its clamping performance is characterized under both IEC 61000-4-2 (±30 kV contact) and IEC 61000-4-5 (8/20 µs, 13 A) waveforms.
The SOD882D package integrates visible side-wettable flanks and a cathode-marked top surface, supporting automated optical inspection (AOI) and reflow soldering per J-STD-020. Thermal design leverages low junction-to-ambient resistance enabled by its 1.0 × 0.6 × 0.4 mm body and copper leadframe construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8 V - Maximum continuous reverse voltage before leakage exceeds 500 nA; defines safe operating range for protected signal lines. |
| VBR | 9.1 V (typ) - Breakdown voltage at 1 mA; ensures reliable turn-on during ESD events without premature conduction. |
| VCL @ 13 A | 18.5 V - Clamped voltage during 8/20 µs surge; limits transient energy delivered to downstream ICs. |
| Cd | 70 pF (typ) - Diode capacitance at 0 V bias and 1 MHz; enables use on USB 2.0 (480 Mbps) and CAN FD (5 Mbps) lines. |
| Rdyn | 0.4 Ω - Dynamic resistance measured at 10 A TLP pulse; determines voltage overshoot and power dissipation during fast transients. |
| PPPM | 286 W - Peak pulse power handling at 8/20 µs; supports robust surge immunity in automotive infotainment and ADAS interfaces. |
| ESD Rating | ±30 kV - IEC 61000-4-2 contact discharge rating; meets stringent automotive EMC requirements for exposed connectors. |
Pinout & Package
SOD882D (DFN1006D-2) is a 2-terminal, leadless ultra-small plastic package measuring 1.0 × 0.6 × 0.4 mm with side-wettable flanks for solder joint inspection. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or lower-potential reference; carries surge current during positive transients on the protected line. |
| 2 | Anode (A) | Connected to the signal line requiring protection; conducts during negative transients when line voltage drops below ground. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Enables asymmetric protection for DC-biased lines (e.g., CAN_H, USB D+), minimizing capacitance impact on signal integrity. |
| AEC-Q101 qualified | Validated for automotive temperature range (−55 °C to +150 °C) and mechanical stress, supporting under-hood and infotainment applications. |
| Side-wettable flanks | Facilitates automated X-ray or AOI inspection of solder joints without requiring cross-sectioning or destructive testing. |
| Low dynamic resistance | 0.4 Ω ensures minimal voltage overshoot during sub-100 ns ESD pulses, preserving logic-level margins of protected receivers. |
| Ultra-small footprint | 1.0 × 0.6 mm area allows placement directly at board edge connectors, reducing inductance in the protection path. |
Applications
| Automotive USB 2.0 Interface | CAN FD Data Line Protection |
|---|---|
|
Use Scenario: Protecting USB 2.0 D+ and D− lines in vehicle infotainment head units exposed to ESD via front-panel connectors. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed within 2 mm of USB connector to limit transient voltage to <22 V during ±8 kV contact discharge. Use Value: 70 pF capacitance avoids signal rise-time degradation at 480 Mbps, while 0.4 Ω Rdyn ensures clamping stability across temperature. |
Use Scenario: Safeguarding CAN FD high-speed data lines (up to 5 Mbps) in ADAS camera modules connected to external harnesses. IC Role / Device Role / Timing Role: Single-line ESD suppressor installed at connector entry point to prevent latch-up in CAN transceivers during hot-plug events. Use Value: AEC-Q101 qualification guarantees operation at 125 °C ambient, and 30 kV ESD rating exceeds ISO 10605 requirements for automotive networks. |
| Industrial Sensor Signal Conditioning | Consumer Display Interface Lines |
|
Use Scenario: Protecting analog sensor outputs (e.g., 0–5 V thermistor signals) in factory automation PLC I/O modules subject to cable discharge events. IC Role / Device Role / Timing Role: Reverse-biased clamp between signal and ground, conducting only during overvoltage excursions above 8 V. Use Value: 5 nA typical leakage at 5 V ensures negligible loading on high-impedance sensor circuits, preserving measurement accuracy. |
Use Scenario: Shielding MIPI D-PHY clock and data lanes in portable medical displays from user-hand ESD during clinical handling. IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor placed adjacent to display connector to maintain signal integrity at 1.5 Gbps. Use Value: 18.5 V clamping voltage at 13 A prevents damage to display driver ICs while 0.65 mm pitch enables dense layout on compact flex PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z8.0T5G | Higher VBR (8.5–9.5 V), same VRWM (8 V), but higher Cd (100 pF typ) and no AEC-Q101 qualification. | Not rated for automotive under-hood use; suitable for consumer-grade USB ports where cost is prioritized over qualification. | Select when AEC-Q101 is not required and layout allows margin for increased capacitance. |
| TPD2E001DRYR | Bidirectional configuration, lower VCL (12 V @ 1 A), higher Cd (12 pF), and integrated dual-channel design. | Designed for differential pairs (e.g., USB D+/D−); lacks unidirectional optimization for DC-biased lines like CAN. | Prefer for symmetric high-speed interfaces; avoid where unidirectional clamping and low leakage are critical. |
Compared with ESD5Z8.0T5G and TPD2E001DRYR, PESD8V0S1ULD-Q uniquely combines AEC-Q101 qualification, ultra-low 0.4 Ω Rdyn, and side-wettable flanks - making it the only option validated for production automotive signal line protection with traceable solder joint reliability.

FAQ
Is PESD8V0S1ULD-Q bidirectional or unidirectional?
PESD8V0S1ULD-Q is strictly unidirectional: it clamps only when the anode voltage exceeds the cathode by ≥9.1 V (breakdown), and blocks reverse current up to 8 V. This architecture minimizes capacitance and leakage for DC-biased signal lines such as CAN_H or USB D+, unlike bidirectional variants that conduct on both polarities.
What does the "Q" suffix indicate in PESD8V0S1ULD-Q?
Per Nexperia's naming convention, the "Q" suffix denotes AEC-Q101 qualification - confirming full compliance with the Automotive Electronics Council's stress test standard for discrete semiconductors, including temperature cycling, HTRB, and ESD robustness validation across −55 °C to +150 °C.
Can this device protect against IEC 61000-4-5 surges?
Yes: PESD8V0S1ULD-Q is rated for 13 A peak pulse current (IPPM) under the 8/20 µs exponential waveform defined in IEC 61000-4-5, delivering 286 W peak pulse power. Its 18.5 V clamping voltage at 13 A ensures downstream ICs remain within safe operating limits during surge events.
How is the cathode identified on the SOD882D package?
The cathode is marked by a visible bar on the top surface of the SOD882D package, aligned with Pin 1 per Table 2 in the datasheet. This marking is optically inspectable and corresponds to the side-wettable flank on the same side - enabling both visual and AOI-based orientation verification during assembly.
