Product details
Overview
PESD15VS2UT from Nexperia is a unidirectional double ESD protection diode in SOT23 package, designed to protect two data or transmission lines against IEC 61000-4-2 level 4 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It features 15 V reverse standoff voltage, 40 V clamping at 5 A, and 32 pF typical capacitance - ideal for high-speed USB 2.0 and parallel port line protection.
For engineers reviewing the PESD15VS2UT datasheet, PESD15VS2UT pinout, PESD15VS2UT application, or PESD15VS2UT equivalent, key selection criteria include bidirectional ESD robustness per line, low clamping voltage under surge stress, ultra-low leakage (<20 nA), and minimal signal-line capacitance for data integrity on 480 Mbps interfaces.
Technical Context
This dual-cathode, common-anode ESD diode implements two independent unidirectional protection paths between pins 1–3 and 2–3. Each path provides precise 15 V standoff with sharp 17.6–18.4 V breakdown at 5 mA and sub-40 V clamping up to 5 A peak pulse current.
Its architecture enables simultaneous protection of two positive-polarity signal lines referenced to ground, with differential resistance of 225 Ω ensuring fast transient response and minimal voltage overshoot during ESD events per IEC 61000-4-2 waveform (0.6–1 ns rise time).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - maximum continuous DC or signal voltage each protected line can sustain without conduction |
| Clamping Voltage | 40 V at 5 A (8/20 µs) - limits transient voltage seen by downstream ICs during surge events |
| Diode Capacitance | 32 pF (typ) at 1 MHz, 0 V - low enough to avoid signal integrity degradation on USB 2.0 or parallel bus lines |
| ESD Withstand | >30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial immunity requirements |
| Peak Pulse Power | 160 W at 8/20 µs - sustains high-energy surges without failure in telecom or peripheral interfaces |
| Reverse Leakage | <20 nA at 15 V - prevents DC loading or bias shift in sensitive analog or logic inputs |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), rated for reflow and wave soldering per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected signal line; conducts ESD current to common anode when line voltage exceeds 15 V |
| 2 | K2 (cathode of diode 2) | Connects to second protected signal line; operates independently from pin 1 for dual-line protection |
| 3 | A (common anode) | Shared return path to system ground; must be routed with low-inductance connection for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional ESD protection | Single SOT23 device protects two independent signal paths without cross-talk or shared cathode limitations |
| Low clamping voltage (40 V @ 5 A) | Ensures downstream logic-level interfaces (e.g., 3.3 V or 5 V microcontrollers) remain within safe operating area during transients |
| Ultra-low leakage (<20 nA) | Maintains signal fidelity and prevents false triggering in high-impedance sensor or audio input circuits |
| 32 pF typical capacitance | Preserves edge rate and eye diagram integrity on 480 Mbps USB 2.0 or 12 Mbps full-speed interfaces |
Applications
| USB 2.0 Data Lines | Parallel Printer Port |
|---|---|
Use Scenario: Protection of D+ and D− lines on USB 2.0 host or peripheral connectors against ESD during hot-plug insertion. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed directly at connector, clamping ESD pulses before reaching USB transceiver IC. Use Value: Prevents latch-up or gate oxide damage in USB PHY while maintaining <100 ps propagation delay and <32 pF loading. | Use Scenario: Shielding bidirectional data/control lines (e.g., STROBE, ACK, BUSY) on legacy IEEE 1284 parallel ports. IC Role / Device Role / Timing Role: Dual-path ESD clamp enabling single-device protection of both forward and reverse signal directions on shared bus lines. Use Value: Eliminates need for two discrete diodes; maintains DC logic levels and supports 2 MB/s transfer rates without signal distortion. |
| Audio Line Inputs | Industrial Serial Interface |
Use Scenario: Safeguarding unbalanced analog audio inputs (e.g., line-in on sound cards) from handling ESD in consumer equipment. IC Role / Device Role / Timing Role: Low-leakage (20 nA) voltage clamp preserving DC bias integrity and preventing audible pop/crackle during discharge events. Use Value: Avoids signal offset drift or amplifier saturation while delivering >30 kV contact ESD immunity per line. | Use Scenario: Protecting RS-232 or RS-485 driver/receiver signal pairs in factory automation controllers exposed to cabinet-level ESD. IC Role / Device Role / Timing Role: Common-anode dual-diode structure allows independent protection of TX and RX lines sharing one ground reference point. Use Value: Reduces PCB footprint by 50% vs. discrete solutions and ensures <40 V clamping during 5 A surge tests per IEC 61000-4-5. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Higher 5.3 V standoff, lower 15 V clamping, but 65 pF capacitance | Better for 3.3 V logic; unsuitable for 15 V tolerant lines or high-speed USB | Select only if protecting sub-5.5 V interfaces where low clamping outweighs capacitance penalty |
| PESD5V0S2UT,215 | 5 V standoff, 12 V clamping, 35 pF capacitance, same SOT23-3 package | Optimized for 3.3 V/5 V digital buses; not rated for 15 V signal rails | Choose for modern low-voltage I/O; avoid for legacy 12/15 V parallel or audio lines |
Compared with PESD15VS2UT, ES5V3U2U-2/TR offers tighter clamping for 3.3 V systems but sacrifices bandwidth due to higher capacitance, while PESD5V0S2UT,215 provides superior low-voltage protection but cannot withstand 15 V DC bias - making PESD15VS2UT uniquely suited for mixed-signal or legacy interface protection.

FAQ
What is the maximum continuous voltage this diode can block on each protected line?
The PESD15VS2UT has a reverse standoff voltage (VRWM) of 15 V, meaning it blocks up to 15 V DC or steady-state signal voltage on each cathode line (pins 1 and 2) relative to the common anode (pin 3) without significant conduction. This rating is verified per IEC 61000-4-2 test conditions at 25 °C ambient temperature.
Can this device protect bidirectional signal lines like those in RS-232 or USB?
No - the PESD15VS2UT is unidirectional only, with cathodes on pins 1 and 2 and a common anode on pin 3. It protects positive-going transients on two separate lines referenced to ground. For true bidirectional protection (e.g., RS-232), a dual-bidirectional device such as PESD5V0S2UT or discrete back-to-back diodes would be required.
How does its 32 pF capacitance affect USB 2.0 signal integrity?
At 32 pF typical (max 70 pF), the PESD15VS2UT introduces negligible impedance above 100 MHz and preserves USB 2.0 eye diagrams up to 480 Mbps. Measured insertion loss remains below 0.5 dB at 240 MHz, ensuring compliance with USB IF signal quality requirements when placed within 5 mm of the connector.
Is this part qualified for automotive applications?
No - the PESD15VS2UT is explicitly marked as non-automotive qualified in its revision history (v.3, April 2023). Nexperia offers automotive-grade alternatives (e.g., PESD15VS2U-Q) with AEC-Q101 qualification, extended temperature range (–40 °C to +125 °C), and enhanced reliability testing for vehicle ECUs and infotainment systems.
