Product details
Overview
PESD15VS2UAT from Nexperia is a unidirectional double ESD protection diode in common-cathode SOT23 package, designed to protect two data lines against IEC 61000-4-2 (±30 kV contact) and IEC 61000-4-5 (5 A surge) transients. It features 15 V reverse standoff voltage, 32 pF typical capacitance at 1 MHz, and ultra-low 1 nA leakage at VRWM, enabling high-speed signal integrity in USB 2.0 and HDMI interfaces.
For engineers reviewing the PESD15VS2UAT datasheet, PESD15VS2UAT pinout, PESD15VS2UAT application, or PESD15VS2UAT equivalent, this device is selected for compact dual-line ESD clamping where low capacitance, precise clamping voltage (40 V at 5 A), and common-cathode routing efficiency are critical in space-constrained PCB layouts.
Technical Context
This dual-diode array operates in unidirectional mode with shared cathode (Pin 3), allowing independent anode connections (Pins 1 and 2) to two separate signal lines referenced below ground. Its clamping behavior is defined by a 17.6–18.4 V breakdown voltage at 5 mA and 40 V clamping at 5 A (8/20 µs), ensuring predictable transient suppression without forward conduction during normal operation.
The device's 32–70 pF capacitance (measured across either anode-to-cathode pair) and 225 Ω differential resistance support high-frequency data lines up to ~500 MHz while maintaining signal fidelity. Thermal derating follows IEC 60134 limits, with peak pulse power dropping to 80% at 100 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous operating voltage before leakage rises significantly; sets upper limit for protected line DC bias. |
| Breakdown Voltage | 17.6–18.4 V at 5 mA - Threshold where diode begins avalanche conduction; defines onset of ESD clamping action. |
| Clamping Voltage | 40 V at 5 A (8/20 µs) - Maximum voltage seen by protected line during worst-case surge; determines downstream IC survivability. |
| Diode Capacitance | 32–70 pF at 1 MHz, 0 V - Total capacitance per channel; directly impacts signal rise time and insertion loss in high-speed links. |
| Peak Pulse Power | 160 W at 8/20 µs - Transient energy-handling capability; enables robust protection against IEC 61000-4-5 surges. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - Number of standardized ESD strikes the device withstands without parametric shift. |
| Reverse Leakage | 1 nA at 15 V - Minimal DC loading on protected lines; preserves signal integrity and reduces power budget impact. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), optimized for automated placement and reflow soldering per IPC-7351B footprint guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Connects to first protected data line (e.g., USB D+); conducts transient current to common cathode during overvoltage. |
| 2 | Anode (Diode 2) | Connects to second protected data line (e.g., USB D−); enables independent clamping for differential pairs. |
| 3 | Common Cathode | Single low-inductance return path to system ground; minimizes loop area and improves ESD response symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-channel protection | Enables discrete grounding of two independent signal lines while sharing one cathode node-reducing PCB trace count and layout complexity. |
| Low 32 pF typical capacitance | Maintains <1% signal attenuation at 100 MHz; suitable for USB 2.0 (480 Mbps), HDMI 1.4 TMDS, and LVDS interfaces. |
| 160 W peak pulse power rating | Withstands 5 A surge currents per channel under IEC 61000-4-5 test conditions without degradation. |
| 1 nA reverse leakage at 15 V | Eliminates measurable DC loading on sensitive analog or low-power digital inputs, preserving accuracy and battery life. |
| IEC 61000-4-2 Level 4 compliance | Validated for ±30 kV contact and ±15 kV air discharge-exceeds industrial and consumer equipment immunity requirements. |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Line Protection |
|---|---|
|
Use Scenario: Protecting D+ and D− differential pair on USB 2.0 host/device ports against user-handling ESD events. IC Role / Device Role: Unidirectional clamping diode array placed immediately after connector, shunting transients to chassis ground. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while adding only 32 pF per line-no equalization required. |
Use Scenario: Safeguarding three TMDS data channels (or two data + clock) on HDMI source/sink connectors. IC Role / Device Role: Dual-channel ESD suppressor per TMDS pair, leveraging common-cathode configuration to minimize ground bounce. Use Value: Enables full 1080p60 signal integrity with <0.5 dB insertion loss at 165 MHz; meets HDMI compliance test margin. |
| Industrial Serial Communication | Audio Line Input Protection |
|
Use Scenario: Shielding RS-485 or CAN FD data lines in factory automation controllers exposed to cable-discharge events. IC Role / Device Role: Bidirectional-capable protection via external pull-down (anodes tied to signal, cathode grounded), handling negative transients. Use Value: Survives repeated 5 A surges per IEC 61000-4-5 while maintaining <15 V clamping at 1 A-preserving receiver common-mode range. |
Use Scenario: Guarding line-in or mic-in jacks on audio codecs against headphone-plug ESD in consumer AV receivers. IC Role / Device Role: Low-leakage (1 nA) clamp on stereo left/right inputs, preventing pop-noise and input-stage saturation. Use Value: Adds no audible distortion (<−100 dB THD+N) and avoids DC offset drift due to negligible leakage current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD9X5.0ST5G | 5.0 V standoff, 120 pF capacitance, 30 kV ESD rating | Better suited for 3.3 V logic rails; higher capacitance limits use to ≤100 Mbps interfaces | Select when protecting lower-voltage I/O with less stringent speed requirements. |
| Vishay ESDESD351 | 35 V standoff, 15 pF capacitance, 20 kV ESD rating | Higher voltage tolerance but reduced ESD robustness; requires external series impedance for full IEC 61000-4-2 compliance | Choose for 24 V industrial sensor lines where low capacitance outweighs ESD margin needs. |
Compared with ESD9X5.0ST5G and ESDESD351, PESD15VS2UAT uniquely balances 15 V standoff, 32 pF capacitance, and ±30 kV ESD rating-making it optimal for 5 V USB/HDMI interfaces requiring both speed and ruggedness without design trade-offs.

FAQ
What is the maximum operating temperature for PESD15VS2UAT?
The PESD15VS2UAT has a maximum junction temperature of 150 °C and an ambient operating range of −65 °C to +150 °C. Derating of peak pulse power begins above 25 °C, reaching 80% at 100 °C junction temperature per Figure 4 in the datasheet.
Can PESD15VS2UAT be used for bidirectional signal lines like RS-232?
No-PESD15VS2UAT is unidirectional only. For true bidirectional protection, two devices must be used back-to-back or a dedicated bidirectional part such as PESD5V0S2UAT (5 V, common-anode) should be selected instead.
How does the common-cathode configuration affect PCB layout?
The common-cathode (Pin 3) requires a single low-inductance ground connection shared by both protected lines. This reduces ground loop area and improves ESD response symmetry but mandates careful star-ground routing to avoid coupling between channels.
Is PESD15VS2UAT automotive-qualified?
No-this variant is non-automotive qualified. Nexperia offers automotive-grade alternatives (e.g., PESD15VS2UAT-Q) with AEC-Q101 qualification, extended temperature testing, and enhanced reliability screening for vehicle applications.
