Product details
Overview
PESD3V3S1ULS from Nexperia is a unidirectional ESD protection diode in a DFN1006BD-2 (SOD882BD) package, designed to protect single signal lines against 30 kV IEC 61000-4-2 contact discharge and 15 A surge pulses per IEC 61000-4-5. It features 3.3 V reverse standoff voltage, 207–300 pF capacitance at 1 MHz, and clamps transients to ≤15.5 V at 20 A. Used in USB, HDMI, and audio interface lines where low capacitance and automotive-grade reliability are required.
For engineers reviewing the PESD3V3S1ULS datasheet, PESD3V3S1ULS pinout, PESD3V3S1ULS application, or PESD3V3S1ULS equivalent, key selection criteria include clamping voltage under 20 A surge, sub-1 µA leakage at 3.3 V, side-wettable flanks for automated optical inspection, AEC-Q101 qualification, and compatibility with high-speed data lines requiring <300 pF capacitance.
Technical Context
This device operates as a unidirectional transient voltage suppressor, conducting only when the anode-to-cathode voltage exceeds the breakdown threshold (~5.2–6 V), thereby shunting ESD energy to ground while maintaining 3.3 V signal integrity on protected lines. Its low differential resistance (0.28 Ω typical) ensures minimal voltage overshoot during fast transients.
The DFN1006BD-2 package enables PCB-level integration near connectors, with side-wettable flanks supporting solder joint quality verification. Thermal design accounts for junction temperatures up to 150 °C and storage down to −65 °C, meeting automotive ambient requirements (−40 to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 3.3 V - Maximum continuous operating voltage before conduction begins; matches 3.3 V logic and interface rails. |
| Clamping Voltage (VCL) | ≤15.5 V at 20 A - Limits peak voltage seen by downstream ICs during IEC 61000-4-5 surge events. |
| Diode Capacitance (Cd) | 207–300 pF at 1 MHz - Enables use on USB 2.0 and audio lines without signal integrity degradation. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact - Meets highest industrial and automotive ESD immunity requirements. |
| Leakage Current (IRM) | <1 µA at 3.3 V - Prevents DC loading of sensitive analog or high-impedance signal paths. |
| Peak Pulse Current (IPPM) | 20 A (8/20 µs) - Supports robust protection against lightning-induced surges in communication ports. |
| Breakdown Voltage (VBR) | 5.2–6.0 V at 5 mA - Ensures reliable turn-on margin above 3.3 V rail while avoiding false triggering. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground; carries transient current during positive ESD events on protected line. |
| 2 | Anode (A) | Connected to signal line being protected; blocks reverse current until breakdown threshold is exceeded. |
Key Features

| AEC-Q101 qualification | Validated for automotive applications including infotainment and body control modules. |
| Low clamping voltage | VCL ≤15.5 V at 20 A ensures downstream 3.3 V logic ICs remain within absolute maximum ratings. |
| Ultra-low leakage | IRM <1 µA prevents signal drift or bias shift in precision analog sensor interfaces. |
| High ESD rating | 30 kV contact discharge withstand supports ruggedized industrial HMI and medical device front panels. |
Applications

IC Role / Device Role / Timing Role: Single-line protector on unidirectional audio signal path, grounded cathode configuration. Use Value: Sub-1 µA leakage avoids audible pop/click artifacts; 30 kV ESD rating exceeds ISO 10605 requirements. | Use Scenario: Guarding RS-232 TX/RX or RS-485 A/B lines in factory automation gateways exposed to field wiring transients. IC Role / Device Role / Timing Role: Point-of-entry protection at DB9 or terminal block, with dedicated ground return path. Use Value: 20 A surge capability handles induced lightning surges; compact DFN package saves space on dense industrial 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 |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (350 pF), same 3.3 V VRWM, lower clamping (12 V at 24 A), non-AEC-Q101 | Better for cost-sensitive consumer electronics; unsuitable for automotive due to missing qualification | Select when lower clamping voltage is prioritized over automotive compliance and board space. |
| Vishay VEML3020-001 | Lower VRWM (2.8 V), higher leakage (5 µA), same DFN1006 package, AEC-Q101 qualified | Optimized for 2.8 V I²C/SPI buses; excessive leakage disqualifies it for high-impedance analog lines | Choose only for 2.8 V systems where tighter voltage margin outweighs leakage penalty. |
Compared with NUP4105MR6T1G and VEML3020-001, PESD3V3S1ULS uniquely balances 3.3 V compatibility, AEC-Q101 qualification, sub-300 pF capacitance, and ≤1 µA leakage-making it optimal for automotive USB/HDMI interfaces where signal fidelity and qualification are jointly critical.

FAQ
What is the maximum operating temperature for PESD3V3S1ULS?
The PESD3V3S1ULS has a maximum junction temperature of 150 °C and operates across an ambient temperature range of −55 °C to +150 °C. Its thermal performance supports placement near heat-generating components in automotive engine control units and industrial motor drives without derating.
Does PESD3V3S1ULS support bidirectional protection?
No. PESD3V3S1ULS is strictly unidirectional: it conducts only when the anode is more positive than the cathode. For bidirectional protection of AC-coupled or dual-polarity lines, a pair of devices or a dedicated bidirectional part like PESD5V0S1BA must be used.
How does side-wettable flank (SWF) benefit manufacturing?
Side-wettable flanks enable automated optical inspection (AOI) of solder fillets on the package edges, verifying solder joint integrity without X-ray. This reduces post-reflow defect escapes in high-volume SMT lines using the DFN1006BD-2 footprint.
Is PESD3V3S1ULS compatible with lead-free reflow profiles?
Yes. The device is qualified for standard lead-free reflow profiles (J-STD-020), with a maximum peak temperature of 260 °C. Its DFN1006BD-2 package uses matte tin plating and is rated for up to three reflow cycles without degradation of ESD performance or solderability.
