Product details
Overview
PESD3V3L1BSL from Nexperia is a bidirectional ESD protection diode in DFN1006-2 (SOD882-S1) package, designed to safeguard one signal line against IEC 61000-4-2 ±25 kV contact/air discharge and IEC 61000-4-5 8/20 µs surges up to 7.5 A. It features 3.3 V reverse stand-off voltage, 11.3 V max clamping at 7.5 A, and 15.5 pF typical capacitance at 1 MHz - ideal for high-speed USB 2.0 and HDMI data lines in portable electronics.
For engineers reviewing the PESD3V3L1BSL datasheet, PESD3V3L1BSL pinout, PESD3V3L1BSL application, or PESD3V3L1BSL equivalent, key selection criteria include clamping voltage under 8/20 µs surge, sub-20 pF capacitance for signal integrity, bidirectional polarity handling, and ultra-small 1.0 mm × 0.6 mm footprint for space-constrained PCB layouts.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure with two anti-parallel silicon diodes sharing a common ground reference. Its low dynamic resistance (0.18 Ω typical at 10 A) ensures rapid voltage clamping during ESD transients, while its 15.5–18 pF capacitance is optimized for <480 Mbps data rates without signal distortion.
The DFN1006-2 package enables direct placement adjacent to connectors, minimizing transient loop inductance. Its 0.60 mm pitch and cathode-marked top surface support automated optical inspection and precise reflow alignment per JESD201A Class 1A whisker requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage (VRWM) | 3.3 V - defines maximum continuous operating voltage before leakage exceeds 100 nA; sets upper limit for protected signal swing. |
| Clamping Voltage (VCL) | 11.3 V max at 7.5 A (8/20 µs) - peak voltage seen by downstream IC during worst-case surge; ensures logic-level compatibility. |
| Peak Pulse Current (IPPM) | 7.5 A (8/20 µs) - IEC 61000-4-5 surge rating; validates robustness against lightning-induced transients on I/O lines. |
| Diode Capacitance (Cd) | 15.5 pF typical at 1 MHz, 0 V bias - low enough to avoid signal rise-time degradation in USB 2.0 (480 Mbps) interfaces. |
| ESD Rating | ±25 kV per IEC 61000-4-2 (contact & air) - exceeds industrial immunity requirements for handheld and peripheral ports. |
| Breakdown Voltage (VBR) | 5.2 V min at 1 mA - ensures reliable turn-on margin above VRWM, preventing premature conduction during normal operation. |
Pinout & Package
DFN1006-2 (SOD882-S1) is a 2-terminal, leadless, ultra-small plastic package measuring 1.0 mm × 0.6 mm × 0.4 mm with 0.60 mm pitch. The cathode marking bar identifies Pin 1; both terminals are cathodes of anti-parallel diodes, enabling symmetrical bidirectional clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode of first diode; connects to protected line when transient is negative relative to ground. |
| 2 | K2 (Cathode 2) | Anode of second diode; connects to protected line when transient is positive relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or differential signals (e.g., USB D+/D−) without polarity constraints. |
| Ultra-low clamping voltage | 11.3 V max at 7.5 A ensures downstream 3.3 V logic ICs remain within absolute maximum ratings during surge events. |
| Low dynamic resistance | 0.18 Ω typical at 10 A minimizes voltage overshoot during fast-rising ESD pulses (<1 ns rise time). |
| Minimal parasitic capacitance | 15.5 pF typical preserves signal integrity in high-speed digital interfaces up to 480 Mbps. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device connectors exposed to user-handling ESD. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector entry point.

IC Role / Device Role: Line-to-ground ESD clamp on each differential pair, leveraging symmetrical bidirectional response. Use Value: Maintains signal fidelity at 2.25 Gbps with sub-12 V clamping, preventing pixel corruption or link dropouts. |
| Smartphone Audio Jacks | Industrial RS-485 Interfaces |
|

IC Role / Device Role: Single-line protector per contact, mounted within 2 mm of jack footprint. Use Value: 3.3 V VRWM aligns with audio codec I/O voltage rails; 11.3 V clamping prevents latch-up in analog front-end ICs. |
Use Scenario: Protecting RS-485 transceiver A/B lines in factory automation gateways exposed to cable-borne surges. IC Role / Device Role: Line-to-ground clamp on each bus wire, rated for 7.5 A 8/20 µs surges per IEC 61000-4-5 Level 3.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher VRWM (5.0 V), higher VCL (14.5 V at 7.5 A), larger SOT-563 package (2.2 mm × 1.35 mm). | Better suited for 5 V systems but adds >3× PCB area; less optimal for USB 2.0 due to 35 pF capacitance. | Select when protecting 5 V logic or where board space is not constrained and higher clamping voltage is acceptable. |
| Vishay VEML3010 | Unidirectional configuration, 3.3 V VRWM, 12.5 V VCL at 7.5 A, same DFN1006-2 footprint but requires external grounding scheme for bidirectional use. | Requires two devices per line for full bidirectional coverage, increasing BOM count and layout complexity. | Choose only if system architecture mandates discrete unidirectional clamps and layout allows dual-device placement. |
Compared with NUP4105MR6T1G and VEML3010, PESD3V3L1BSL delivers superior signal integrity (15.5 pF vs. 35 pF), smaller footprint (1.0 mm × 0.6 mm), and true single-device bidirectional protection - making it optimal for miniaturized, high-speed interface designs.

FAQ
What is the maximum operating temperature for PESD3V3L1BSL?
The PESD3V3L1BSL has a maximum junction temperature (Tj) of 125 °C and an ambient operating range of −55 °C to +125 °C. Its thermal resistance (Rthj-a) is not specified in the datasheet, but the DFN1006-2 package relies on PCB copper area for heat dissipation during transient events - no heatsink required for ESD-only duty cycles.
Can PESD3V3L1BSL protect differential pairs without skew?
Yes - because it uses matched anti-parallel diodes in a single die, PESD3V3L1BSL provides symmetrical clamping response on both polarities with identical dynamic resistance (0.18 Ω) and capacitance (15.5 pF), ensuring minimal inter-pair timing skew in USB 2.0 or HDMI TMDS applications when placed per-line.
Is PESD3V3L1BSL compliant with RoHS and REACH?
Yes - PESD3V3L1BSL meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. It is halogen-free, lead-free, and complies with Nexperia's green policy; the "L" suffix in the part number explicitly denotes lead-free termination and RoHS-compliant packaging.
How should PESD3V3L1BSL be placed on the PCB for optimal ESD performance?
Place PESD3V3L1BSL within 2 mm of the protected connector pin, with shortest possible traces to both the signal line and ground plane. Use dedicated ground vias directly beneath the package, avoid shared return paths, and ensure the ground connection is low-inductance - layout guidelines are validated per IEC 61000-4-2 test setup in Nexperia's application note AN10792.
