Product details
Overview
PESD12VS2UQ,115 from Nexperia is a unidirectional double ESD protection diode in SOT663 package, designed to protect two signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 12 V reverse standoff voltage, 38–100 pF capacitance at 1 MHz, and clamping voltage of 19 V at 1 A and 35 V at 5 A. It serves in high-speed data line protection for USB, HDMI, and industrial serial interfaces.
For engineers reviewing the PESD12VS2UQ,115 datasheet, PESD12VS2UQ,115 pinout, PESD12VS2UQ,115 application, or PESD12VS2UQ,115 equivalent, key selection criteria include low clamping voltage under surge, sub-1 nA leakage at 12 V, dual-line unidirectional topology, and SOT663 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a common-anode dual-diode configuration: pins 1 and 2 are cathodes for two independent protection paths, while pin 3 serves as the shared anode tied to ground. Its unidirectional architecture enables protection only on negative-going transients relative to ground - ideal for signals referenced to system ground with no negative swing below it.
It meets IEC 61000-4-2 level 4 (±30 kV contact) and IEC 61000-4-5 (8/20 μs surge, 5 A peak pulse current), delivering 150 W peak pulse power per diode path. The 38–100 pF capacitance range ensures minimal signal integrity impact on lines up to 100 Mbps without requiring impedance compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - Maximum continuous reverse voltage before leakage exceeds 1 nA; sets upper limit for protected line DC bias. |
| VCL @ IPP = 5 A | 35 V - Clamped voltage during 8/20 μs surge; determines maximum transient overvoltage seen by downstream IC. |
| Cd @ 1 MHz, VR = 0 V | 38–100 pF - Low capacitance preserves signal rise time and bandwidth on high-speed lines like USB 2.0. |
| IPP (max) | 5 A - Peak surge current capability per diode path per IEC 61000-4-5; defines robustness against lightning-induced surges. |
| VESD (IEC 61000-4-2) | ±30 kV contact - ESD immunity level validated for direct human discharge events into protected ports. |
| IRM @ VRWM | <1 nA - Ultra-low leakage avoids loading of high-impedance or battery-powered signal lines. |
| PPP | 150 W @ tp = 8/20 μs - Peak pulse power handling per diode; supports repeated surge events without thermal runaway. |
Pinout & Package
SOT663 ultra-small flat-lead surface-mount package (1.7 × 1.3 × 0.5 mm, 0.65 mm pitch); thermally efficient for PCB-mounted transient dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Connects to first protected signal line; conducts ESD current to common anode (pin 3) during negative transients. |
| 2 | Cathode 2 | Connects to second protected signal line; independent conduction path sharing ground return via pin 3. |
| 3 | Common Anode | Ground reference terminal; must be connected to low-inductance system ground plane for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Enables separate protection of two grounded-referenced signals (e.g., D+ and D−) using single compact SOT663 footprint. |
| Low clamping voltage (19 V @ 1 A) | Keeps transient overvoltage below typical 20 V absolute maximum ratings of USB PHY and RS-485 transceivers. |
| Sub-1 nA reverse leakage | Prevents DC loading on high-Z sensor outputs or battery-backed lines where microamp-level current matters. |
| 38–100 pF capacitance | Supports signal integrity on 480 Mbps USB 2.0 and 100 Mbps RS-422 links without equalization or layout de-tuning. |
| IEC 61000-4-2 level 4 compliance | Validated for ±30 kV contact discharge - exceeds industrial and medical equipment immunity requirements. |
Applications
| USB 2.0 Port Protection | HDMI DDC Channel Protection |

FAQ
Is PESD12VS2UQ,115 suitable for bidirectional signal lines?
No - it is unidirectional only, with cathodes on pins 1 and 2 and a common anode on pin 3. It protects signals referenced to ground against negative transients. For bidirectional protection (e.g., USB D+/D− with ± swings), a dedicated bidirectional array like PESD5V0S2UAT,115 is required.
What is the maximum recommended PCB trace length between PESD12VS2UQ,115 and the protected connector?
Trace length should be ≤3 mm from each cathode pin to its respective signal line, and the common anode (pin 3) must connect directly to a solid ground plane with ≥2 vias. Longer traces increase inductance, raising clamped voltage during fast ESD events and degrading protection efficacy.
Does PESD12VS2UQ,115 meet automotive qualification standards?
It is not AEC-Q200 qualified. While it satisfies IEC 61000-4-2 and IEC 61000-4-5, automotive applications require additional temperature cycling, humidity testing, and lifetime validation per AEC-Q200. Nexperia offers automotive-grade variants such as PESD12VS2UAX,115 for those use cases.
How does the 38–100 pF capacitance tolerance affect high-speed design?
The capacitance varies with applied reverse voltage - lower at higher VR - so design margin must account for worst-case 100 pF at 0 V bias. For 480 Mbps USB 2.0, this adds <0.2 UI jitter and requires controlled-impedance routing; layout simulation is recommended when operating near bandwidth limits.
