Product details
Overview
PESD3V3L2BT from Nexperia is a low-capacitance, double bidirectional ESD protection diode in SOT23 package, designed to safeguard two signal lines against IEC 61000-4-2 level 4 (±30 kV contact) and IEC 61000-4-5 (15 A surge) transients. It features 3.3 V reverse standoff voltage, 101 pF capacitance at 1 MHz, and 26 V clamping voltage at 15 A, making it suitable for high-speed USB, HDMI, and SIM card interfaces.
For engineers reviewing the PESD3V3L2BT datasheet, PESD3V3L2BT pinout, PESD3V3L2BT application, or PESD3V3L2BT equivalent, key selection criteria include bidirectional clamping capability, ultra-low leakage (90 nA), AEC-Q101 qualification, and SOT23 footprint compatibility with space-constrained portable electronics layouts.
Technical Context
This device implements a dual-cathode, triple-terminal architecture where pins 1 and 2 serve as independent cathodes for two protected lines, and pin 3 functions as a shared double cathode node-enabling symmetrical bidirectional clamping without external biasing. Its low 101 pF capacitance ensures minimal signal integrity impact on data lines up to 480 Mbps.
The diode operates within ±30 kV ESD tolerance per IEC 61000-4-2 and withstands 15 A 8/20 µs surge pulses per IEC 61000-4-5, with clamping limited to 26 V at peak current. Junction temperature remains within safe limits up to 150 °C, supporting operation in automotive and industrial ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Ensures no conduction during normal 3.3 V logic-level signaling, preserving signal integrity. |
| Diode Capacitance | 101 pF @ 1 MHz - Enables use on high-speed interfaces (e.g., USB 2.0, SDIO) without excessive signal attenuation. |
| Clamping Voltage | 26 V @ 15 A - Limits transient voltage across protected ICs to non-destructive levels during surge events. |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 - Meets highest industrial and automotive ESD immunity requirements. |
| Leakage Current | 90 nA @ 3.3 V - Prevents DC loading of sensitive analog or RF signal paths. |
| Peak Pulse Power | 350 W @ 8/20 µs - Sustains high-energy transients without thermal runaway or parametric shift. |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch) with gull-wing leads and JEDEC TO-236AB outline compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 | Cathode for Line 1 - Forms one half of bidirectional clamp path between Line 1 and common cathode node. |
| 2 | K2 | Cathode for Line 2 - Forms second half of bidirectional clamp path between Line 2 and common cathode node. |
| 3 | CC | Double Cathode - Shared return node enabling simultaneous, independent clamping of both signal lines to ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line bidirectional protection | Single SOT23 device protects two independent signal paths without polarity constraints or external components. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD22 standards. |
| Ultra-low leakage | 90 nA max reverse current preserves battery life and avoids false triggering in low-power sensor interfaces. |
| Low clamping resistance | 400 Ω differential resistance enables rapid voltage suppression during fast-rising ESD events (<1 ns rise time). |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protection of differential USB 2.0 D+ and D− lines in portable docking stations and OTG adapters.

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 NUP4201MR6T1G | Higher capacitance (130 pF), lower ESD rating (±15 kV), same SOT23-3L package. | Not qualified to AEC-Q101; unsuitable for automotive infotainment displays. | Select when cost sensitivity outweighs automotive qualification and high-speed signal integrity needs. |
| Vishay ESDE03-2 | Lower clamping voltage (17 V), higher leakage (200 nA), identical 3.3 V VRWM and SOT23 footprint. | Lacks IEC 61000-4-5 surge rating; limited to ESD-only scenarios. | Prefer for battery-powered wearables where ultra-low clamping is critical and surge immunity is not required. |
Compared with NUP4201MR6T1G and ESDE03-2, PESD3V3L2BT uniquely combines AEC-Q101 qualification, ±30 kV ESD rating, and IEC 61000-4-5 surge compliance in a single SOT23 device-making it the only option validated for automotive-grade dual-line protection with full transient immunity coverage.

FAQ
What is the maximum operating temperature for PESD3V3L2BT?
The PESD3V3L2BT supports continuous operation up to 150 °C junction temperature and −65 °C to +150 °C ambient temperature range. Its thermal design allows reliable performance in automotive under-dash environments and industrial enclosures without derating below 125 °C ambient.
Can PESD3V3L2BT protect AC-coupled signal lines?
Yes-its bidirectional structure enables protection of signals swinging above and below ground, such as USB differential pairs or HDMI TMDS channels. The symmetric V-I curve ensures equal clamping in both polarities without requiring DC bias or external components.
Is the SOT23 footprint compatible with automated optical inspection (AOI)?
Yes-the SOT23 package has standardized gull-wing leads with 1.9 mm pitch and defined solder land patterns per Nexperia's sot023_fr and sot023_fw footprints. Its consistent marking (V3%) and coplanarity meet IPC-A-610 Class 2 AOI detection thresholds.
Does PESD3V3L2BT require series impedance for optimal clamping?
No-its low dynamic resistance (400 Ω) and fast response (<1 ns) enable direct placement at connectors without added series resistors. However, minimizing PCB trace inductance between the device and protected line is critical to achieving specified 26 V clamping at 15 A.
