Product details
Overview
PESD15VS2UT-Q from Nexperia is a unidirectional double ESD protection diode in SOT23 package, designed to safeguard 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, HDMI, and automotive infotainment interfaces.
For engineers reviewing the PESD15VS2UT-Q datasheet, PESD15VS2UT-Q pinout, PESD15VS2UT-Q application, or PESD15VS2UT-Q equivalent, key selection criteria include clamping voltage under 5 A surge, sub-70 pF line-to-ground capacitance, AEC-Q101 qualification, and common-anode dual-cathode topology for compact bidirectional-line protection with single-device footprint.
Technical Context
This device implements a common-anode dual-diode architecture where pins 1 and 2 serve as independent cathodes and pin 3 is the shared anode - enabling simultaneous unidirectional protection of two signal paths referenced to ground. Its low 225 Ω differential resistance and ultra-low 20 nA reverse leakage ensure minimal signal distortion and DC loading on protected lines.
Rated for 160 W peak pulse power (8/20 µs), it meets automotive-grade transient immunity requirements per AEC-Q101, with junction temperature tolerance up to 150 °C and storage range from −65 °C to +150 °C - supporting under-hood and infotainment module deployment without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - maximum continuous DC or RMS signal voltage before conduction begins; defines safe operating window for 12 V–15 V data buses. |
| Clamping Voltage | 40 V at 5 A (8/20 µs) - limits transient voltage seen by downstream ICs during surge events, protecting 3.3 V/5 V logic interfaces. |
| Diode Capacitance | 32 pF typical (1 MHz, 0 V) - ensures minimal signal integrity impact on high-speed lines such as USB 2.0 (480 Mbps) and LVDS. |
| ESD Withstand | >30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial and automotive ESD immunity requirements for exposed connectors. |
| Peak Pulse Power | 160 W (8/20 µs) - sustains high-energy surges without failure, validated per IEC 61000-4-5 waveform standards. |
| Leakage Current | <20 nA at 15 V - prevents measurable DC loading on precision analog or high-impedance sensor inputs. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm, 1.9 mm lead pitch); thermally optimized for PCB reflow and wave soldering per JEDEC TO-236AB outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to first protected line (e.g., USB D+); conducts ESD current to common anode when line voltage exceeds VRWM. |
| 2 | Cathode (Diode 2) | Connects to second protected line (e.g., USB D−); enables dual-line protection with single-component footprint and shared return path. |
| 3 | Common Anode | Connected to system ground; provides unified low-inductance surge return path for both diodes, minimizing loop area. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including infotainment, body control, and ADAS sensor interfaces with full stress-test compliance. |
| Low clamping voltage | 40 V at 5 A ensures downstream 3.3 V/5 V transceivers remain within absolute maximum ratings during surge events. |
| Ultra-low capacitance | 32 pF typical enables use on >100 Mbps data lines without measurable rise-time degradation or insertion loss. |
| Common-anode dual-diode | Reduces PCB real estate vs. discrete diodes and eliminates mismatched clamping between channels in differential pairs. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting USB 2.0 D+ and D− lines from ESD during hot-plug events in automotive head units and docking stations. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed within 3 mm of USB connector, clamping fast-rising ESD pulses before they reach USB PHY. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while maintaining <1 ns response time and <70 pF total line capacitance. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) SDA/SCL lines against ESD in flat-panel displays and media receivers. IC Role / Device Role / Timing Role: Dual-line ESD clamp on 5 V-tolerant I²C bus, sharing ground return to minimize crosstalk and layout complexity. Use Value: Maintains I²C timing integrity (400 kHz standard mode) with sub-20 nA leakage and no DC voltage drop across protected lines. |
| Automotive Infotainment Audio Lines | Industrial Parallel Port Interfaces |
Use Scenario: Shielding analog audio input/output lines (e.g., AUX-in, speaker outputs) in vehicle entertainment systems from handling ESD. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on ±12 V audio rails, referenced to chassis ground with minimal signal attenuation. Use Value: Preserves SNR >95 dB and THD+N <0.01% by limiting capacitance to 32 pF and leakage to <20 nA at 15 V bias. |
Use Scenario: Hardening legacy parallel printer ports (e.g., Centronics) in factory automation controllers against field ESD exposure. IC Role / Device Role / Timing Role: Dual-channel protection for STROBE and DATA lines, leveraging common-anode configuration to reduce ground bounce during multi-pin discharges. Use Value: Enables reliable 1 Mbps parallel data transfer with no added propagation delay and full IEC 61000-4-2 Level 4 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP2114MR6T1G | Higher 17 V VRWM, 45 V clamping at 5 A, 55 pF capacitance - less suitable for 15 V-tolerant high-speed lines. | Targeted at 3.3 V/5 V logic; not AEC-Q101 qualified - limited to industrial, non-automotive use. | Select when lower VRWM margin is acceptable and automotive qualification is not required. |
| Vishay VEML6030X01 | Photodiode-based ambient light sensor - not an ESD protector; incompatible function and pinout. | N/A - misidentified part; excluded from functional comparison. | Not applicable; this is a sensor, not a protection device - verify part number before substitution. |
Compared with NUP2114MR6T1G, PESD15VS2UT-Q offers tighter 15 V standoff, lower 40 V clamping, and AEC-Q101 qualification - making it superior for automotive USB/HDMI protection where voltage margin and reliability are critical; VEML6030X01 is functionally unrelated and must be excluded from ESD protection consideration.

FAQ
What is the maximum recommended PCB trace length between PESD15VS2UT-Q and the protected connector?
The datasheet specifies placement "as close to the input terminal or connector as possible" - industry best practice limits trace length to ≤3 mm from diode cathodes to connector pins. Longer traces increase inductance, degrading clamping performance during sub-nanosecond ESD transients and risking overshoot beyond 40 V.
Can PESD15VS2UT-Q protect bidirectional data lines like RS-485 or CAN?
No - it is unidirectional only, with cathodes on pins 1 and 2 and common anode on pin 3. Bidirectional protection requires either two back-to-back diodes or a dedicated bidirectional array. For RS-485/CAN, use Nexperia's PESD5V0S1BA or similar symmetric-clamp devices instead.
Does the 32 pF capacitance apply to each diode individually or combined?
The 32 pF typical value (measured at 1 MHz, 0 V) is specified per diode - i.e., from pin 1 to pin 3 and from pin 2 to pin 3 independently. Total capacitance seen by a differential pair is not additive, as both diodes share the same anode node and ground reference.
Is thermal derating required when operating above 85 °C ambient?
Yes - Figure 4 shows peak pulse power drops to ~80% of 160 W at 125 °C junction temperature. For continuous operation above 85 °C ambient, reduce surge repetition rate or ensure adequate PCB copper area (≥100 mm² per diode) to maintain Tj ≤125 °C during transient events.
