Product details
Overview
PESD3V3T1BLS from Nexperia is a bidirectional ESD protection diode in DFN1006BD-2 (SOD882BD) package, designed to protect one signal line against IEC 61000-4-2 contact discharge up to 30 kV and IEC 61000-4-5 surges up to 10.5 A (8/20 µs). It features 3.3 V reverse standoff voltage, 9.3–11 V clamping at 10 A, and 20–25 pF capacitance at 1 MHz - ideal for high-speed USB 2.0 and HDMI interface protection.
For engineers reviewing the PESD3V3T1BLS datasheet, PESD3V3T1BLS pinout, PESD3V3T1BLS application, or PESD3V3T1BLS equivalent, key selection criteria include bidirectional clamping symmetry, side-wettable flanks for automated optical inspection (AOI), AEC-Q101 qualification for automotive infotainment interfaces, and low dynamic resistance (<0.21 Ω) under transient stress.
Technical Context
This device implements a symmetric dual-cathode TVS structure enabling equal clamping in both polarities, with breakdown voltage of 4.7–8.7 V at 5 mA and reverse leakage <50 nA at 3.3 V. Its ultra-low 20–25 pF capacitance ensures minimal signal integrity impact on 480 Mbps USB 2.0 lines.
The DFN1006BD-2 package integrates side-wettable flanks for solder joint inspection and supports reflow profiles per J-STD-020. Thermal design accommodates junction temperatures up to 150 °C, validated under AEC-Q101 stress conditions including temperature cycling and HTRB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3 V reverse standoff voltage - blocks normal signal swing without leakage in 3.3 V I/O systems. |
| VBR | 4.7–8.7 V breakdown at 5 mA - defines turn-on threshold for ESD clamping onset. |
| VCL @ 10 A | 9.3–11 V clamping voltage (8/20 µs) - limits transient overvoltage seen by downstream ICs. |
| Cd | 20–25 pF at 1 MHz, 0 V - preserves signal rise/fall times in USB 2.0 and audio interfaces. |
| IPPM | 10.5 A peak pulse current (8/20 µs) - withstands IEC 61000-4-5 surge events. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - exceeds Level 4 immunity requirements. |
| Rdyn | 0.12–0.21 Ω dynamic resistance - minimizes voltage overshoot during fast transients. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless 2-terminal 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 reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode 1 | First cathode terminal; marking band identifies this pin - forms one half of symmetric bidirectional clamping path. |
| 2 (K2) | Cathode 2 | Second cathode terminal - completes symmetrical dual-cathode configuration enabling equal positive/negative clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping symmetry | Equal VCL (9.3–11 V) and Rdyn (0.12–0.21 Ω) for ± polarity transients - eliminates polarity-dependent protection gaps. |
| Side-wettable flanks (SWF) | Exposed copper on package sides enables automated optical inspection of solder joints - critical for automotive PCB assembly traceability. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, TC, and HTRB - supports infotainment and ADAS sensor interface use. |
| Low dynamic resistance | 0.12 Ω (positive) / 0.21 Ω (negative) - reduces clamping voltage overshoot during sub-100 ns ESD events. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against user-handling ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 3 mm of USB connector. Use Value: 20–25 pF capacitance avoids signal integrity degradation at 480 Mbps; 30 kV ESD rating exceeds IEC 61000-4-2 Level 4. |
Use Scenario: Shielding TMDS clock and data pairs in flat-panel display interfaces from cable-discharge events. IC Role / Device Role / Timing Role: Low-capacitance clamp on each differential pair, mounted adjacent to HDMI receptacle. Use Value: Symmetric clamping prevents DC offset shift in AC-coupled TMDS; SWF package enables AOI in high-volume display module production. |
| Automotive Infotainment | Industrial Sensor Interfaces |
Use Scenario: Safeguarding touch controller I²C lines in vehicle center consoles exposed to cabin ESD. IC Role / Device Role / Timing Role: AEC-Q101-qualified protector on bidirectional SDA/SCL traces near connector entry point. Use Value: Junction temperature rating up to 150 °C supports operation in hot vehicle cabins; 3.3 V VRWM matches MCU I/O rail. |
Use Scenario: Protecting RS-485 transceiver inputs in factory automation nodes subject to long-cable surge coupling. IC Role / Device Role / Timing Role: Surge-rated clamp on differential bus lines, placed before transceiver ESD diodes. Use Value: 10.5 A IPPM rating handles IEC 61000-4-5 Line-to-Ground surges; low IRM (<50 nA) avoids loading 125 kbps data rates. |
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 Cd (35 pF), non-AEC-Q101 rated | Suitable for 5 V industrial logic but not automotive; less suitable for USB 2.0 due to capacitance | Select when protecting 5 V interfaces where AEC-Q101 is not required and higher clamping voltage is acceptable. |
| Vishay VEML6030X01 | Photodiode + integrated ESD protection; not a standalone TVS - lacks 30 kV ESD rating and 10.5 A surge capability | Designed for ambient light sensing, not general-purpose signal line protection | Not functionally equivalent - avoid for dedicated ESD protection roles; only applicable in combined sensing/protection subsystems. |
Compared with NUP4105MR6T1G, PESD3V3T1BLS offers lower capacitance and automotive qualification but tighter 3.3 V standoff; VEML6030X01 is not a drop-in replacement as it integrates sensing functionality and omits surge robustness metrics.

FAQ
What is the maximum operating temperature for PESD3V3T1BLS?
The PESD3V3T1BLS supports a junction temperature range up to 150 °C and an ambient operating range of −55 °C to +150 °C. This rating is verified per AEC-Q101 test conditions including high-temperature reverse bias and temperature cycling, making it suitable for under-hood automotive applications and industrial environments with elevated thermal loads.
Does PESD3V3T1BLS require external biasing or control signals?
No - PESD3V3T1BLS is a passive bidirectional TVS diode with no control pins, power supply, or biasing requirements. It operates solely via avalanche breakdown above its VBR threshold and provides automatic clamping during ESD or surge events without any active circuitry or configuration.
How does the side-wettable flank (SWF) feature benefit manufacturing?
The side-wettable flanks on the DFN1006BD-2 package expose solderable metal along the package edges, enabling automated optical inspection (AOI) of solder joint formation during reflow. This improves first-pass yield and traceability in automotive and high-reliability production lines where solder joint integrity is audited per IATF 16949 requirements.
Can PESD3V3T1BLS protect AC-coupled differential signals like HDMI TMDS?
Yes - its symmetric bidirectional structure and low 20–25 pF capacitance make it suitable for AC-coupled differential pairs. The device clamps equally on both polarities without introducing DC offset, and its fast response time (<1 ns) ensures effective suppression of ESD transients before they reach the receiver input stage.
