Product details
Overview
PESD3V3L1ULS from Nexperia is a unidirectional ESD protection diode in DFN1006BD-2 (SOD882BD) package, designed to protect one signal line against 30 kV IEC 61000-4-2 contact discharge and 14 A surge pulses per IEC 61000-4-5. It features 3.3 V reverse standoff voltage, 105–160 pF capacitance at 1 MHz, and clamps transients to ≤17.5 V at 14 A. Used in USB, HDMI, and audio interface lines where low capacitance and fast response are critical.
For engineers reviewing the PESD3V3L1ULS datasheet, PESD3V3L1ULS pinout, PESD3V3L1ULS application, or PESD3V3L1ULS equivalent, key selection criteria include clamping voltage under 14 A surge, sub-200 pF capacitance at signal frequencies, side-wettable flanks for automated optical inspection, and compatibility with 0.65 mm pitch PCB layouts.
Technical Context
This device operates as a single-line unidirectional TVS diode, leveraging silicon avalanche breakdown to divert ESD energy to ground when reverse voltage exceeds 5.2–6 V. Its ultra-low leakage (<2 µA at 3.3 V) ensures minimal impact on high-impedance signal paths.
The DFN1006BD-2 package integrates side-wettable flanks for solder joint inspection and supports reflow profiles compliant with IPC-J-STD-020. Dynamic resistance of 0.46 Ω (TLP, 10 A) enables rapid voltage clamping during sub-nanosecond ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V - Maximum continuous reverse voltage before leakage rises; sets upper limit for protected line DC bias. |
| VBR | 5.2–6 V - Breakdown threshold at 5 mA; defines onset of clamping action during overvoltage events. |
| VCL @ 14 A | ≤17.5 V - Clamped voltage during 8/20 µs surge; determines maximum stress seen by downstream IC. |
| Cd @ 1 MHz | 105–160 pF - Signal-line capacitance at zero bias; impacts high-speed data integrity (e.g., USB 2.0 eye diagram). |
| IRM @ 3.3 V | <2 µA - Reverse leakage current; ensures negligible DC loading on sensitive analog or logic inputs. |
| ESD Rating | ±30 kV - IEC 61000-4-2 contact discharge level; qualifies for industrial and consumer port-level protection. |
| IPPM | 14 A - Peak pulse current per IEC 61000-4-5; withstands lightning-induced surges on external interfaces. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with 0.65 mm pitch and side-wettable flanks for AOI-compatible solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground; carries diverted ESD/surge current to reference plane. |
| 2 | Anode (A) | Connected to protected signal line; reverse-biased during normal operation, forward-conducting during ESD. |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection of solder fillets without X-ray, improving manufacturing yield in high-volume SMT lines. |
| Clamping voltage ≤17.5 V @ 14 A | Ensures downstream logic ICs (e.g., 3.3 V I/O) remain within absolute maximum ratings during surge events. |
| Capacitance 105–160 pF @ 1 MHz | Preserves signal integrity on 480 Mbps USB 2.0 or 720p HDMI TMDS lines without measurable rise-time degradation. |
| Leakage <2 µA @ 3.3 V | Prevents DC offset or false triggering in high-impedance sensor interfaces and analog front-ends. |
| 30 kV ESD rating (IEC 61000-4-2) | Meets Level 4 immunity requirements for handheld and desktop peripheral ports exposed to human-body model discharges. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device connectors against user-hand ESD events. IC Role / Device Role: Unidirectional transient voltage suppressor placed between connector and USB PHY IC. Use Value: 105–160 pF capacitance avoids signal distortion at 480 Mbps; ≤17.5 V clamping prevents PHY latch-up or I/O damage. | Use Scenario: ESD safeguard for TMDS clock and data pairs on HDMI source/sink ports. IC Role / Device Role: Line-level protector mounted adjacent to HDMI receptacle to minimize inductance. Use Value: Low dynamic resistance (0.46 Ω) ensures fast clamping response to sub-ns ESD pulses without degrading differential skew. |
| Audio Line Inputs | Industrial Serial Interfaces |
Use Scenario: Protection of unbalanced analog audio inputs (e.g., 3.5 mm jack) in consumer AV receivers. IC Role / Device Role: Ground-referenced shunt diode on line-to-ground path for positive-only transients. Use Value: 3.3 V VRWM matches typical audio codec supply rails; <2 µA leakage avoids DC bias shift in op-amp input stages. | Use Scenario: Surge suppression on RS-232 or RS-485 transceiver lines in factory automation equipment. IC Role / Device Role: Single-line protector on driver output or receiver input, referenced to local ground. Use Value: 14 A IPPM rating handles induced surges from nearby motor switching; side-wettable flanks support IPC-A-610 Class 3 assembly verification. |
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 (180 pF typ), lower VRWM (3.0 V), same DFN1006 package. | Better suited for 3.0 V systems but may degrade signal integrity above 100 MHz. | Select when system rail is 3.0 V and bandwidth <100 MHz; avoid for USB 2.0 or HDMI. |
| Vishay VEML3020X01 | Lower ESD rating (20 kV), higher clamping (22 V @ 14 A), same footprint. | Acceptable for cost-sensitive industrial I/O where 30 kV compliance is not required. | Choose for non-certified applications with relaxed ESD immunity; verify downstream IC VIO margin. |
Compared with NUP4105MR6T1G and VEML3020X01, PESD3V3L1ULS delivers superior high-frequency performance due to its 105–160 pF capacitance and tighter 17.5 V clamping, making it optimal for certified USB/HDMI protection where signal fidelity and immunity compliance are jointly constrained.

FAQ
What is the maximum operating temperature for PESD3V3L1ULS?
The junction temperature must not exceed 150 °C, and ambient operating range is −55 °C to +150 °C. Thermal derating is required above 85 °C ambient; power dissipation drops linearly to zero at 150 °C junction temperature per the Absolute Maximum Ratings table.
Can PESD3V3L1ULS be used for bidirectional signal lines?
No - it is strictly unidirectional and only protects against transients with polarity relative to ground (anode to signal, cathode to GND). For bidirectional lines like USB D+/D− differential pairs, two devices or a dedicated bidirectional array such as PESD5V0U1BB must be used.
Is the marking "8N" on the device body sufficient for traceability?
Yes - "8N" is the official Nexperia marking code for PESD3V3L1ULS per Table 4 of the datasheet. It corresponds uniquely to this part number and batch-agnostic device specification, enabling visual identification and automated optical verification during assembly.
Does PESD3V3L1ULS meet automotive AEC-Q200 requirements?
No - this device is not AEC-Q200 qualified. Nexperia explicitly states in the Legal Information section that unless otherwise specified, products are not automotive qualified. For automotive applications, use the AEC-Q200–qualified PESD3V3L1ULS-Q variant with documented qualification test reports.
