Product details
Overview
PESD3V3S2UT from Nexperia is a unidirectional double ESD protection diode in SOT23 package, designed to protect two data lines against IEC 61000-4-2 level 4 ESD (±30 kV contact) and IEC 61000-4-5 surge (18 A, 8/20 µs). It features 3.3 V reverse standoff voltage, 207–300 pF capacitance, and 20 V clamping voltage at 18 A - ideal for high-speed USB, HDMI, or parallel port interfaces.
For engineers reviewing the PESD3V3S2UT datasheet, PESD3V3S2UT pinout, PESD3V3S2UT application, or PESD3V3S2UT equivalent, key selection criteria include bidirectional line protection capability, low clamping voltage under 18 A surge, sub-1 µA reverse leakage at 3.3 V, ultra-low capacitance for signal integrity, and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
This dual-cathode, common-anode ESD diode implements two independent unidirectional protection paths between pins 1–3 and 2–3. Its clamping behavior is defined by a 5.2–6 V breakdown voltage and 20 V max clamping at 18 A, enabling robust transient suppression without forward conduction during normal 3.3 V operation.
The device operates within –65 °C to +150 °C junction temperature range and delivers 330 W peak pulse power per line. Its 207–300 pF capacitance (measured pin-to-pin) is optimized for high-speed data lines where signal integrity and minimal loading are critical.
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 |
| Clamping Voltage | 20 V at 18 A - limits transient voltage to safe levels for downstream 3.3 V ICs |
| Diode Capacitance | 207–300 pF - low enough to avoid signal distortion on USB 2.0 or parallel bus lines |
| ESD Rating | ±30 kV contact discharge - exceeds IEC 61000-4-2 Level 4 for industrial reliability |
| Peak Pulse Power | 330 W - sustains 8/20 µs surges without degradation |
| Reverse Leakage | <0.7 µA at 3.3 V - negligible current draw in standby, preserving signal rail integrity |
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 line; conducts transient current to common anode when line voltage exceeds 3.3 V |
| 2 | K2 (cathode of diode 2) | Connects to second protected line; enables independent protection of dual unidirectional signals |
| 3 | A (common anode) | Shared ground reference point; must be connected directly to low-inductance system ground |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection | Single SOT23 device protects two independent 3.3 V signal paths without cross-talk |
| Low clamping voltage | 20 V max at 18 A ensures downstream 3.3 V logic ICs remain within absolute maximum ratings |
| Ultra-low capacitance | 207–300 pF minimizes signal rise-time degradation on high-speed data lines up to 480 Mbps |
| Sub-microamp leakage | <0.7 µA at VRWM preserves voltage margin and reduces static power loss in battery-powered systems |
Applications
| USB 2.0 Interface Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting USB D+ and D− lines from ESD events during hot-plug insertion in embedded host controllers. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed at connector entry point before USB transceiver. Use Value: 207–300 pF capacitance avoids signal integrity loss while maintaining <1 ns response time to ±30 kV ESD pulses. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) clock and data lines against user-handling ESD in consumer AV receivers. IC Role / Device Role / Timing Role: Dual-path ESD clamp referenced to system ground, co-located with HDMI receptacle. Use Value: 3.3 V standoff matches DDC logic levels; 20 V clamping prevents damage to I²C-compatible sink devices. |
| Parallel Printer Port Protection | Industrial RS-232 Signal Line Protection |
Use Scenario: Shielding legacy parallel port data lines (D0–D7) from electrostatic discharge in factory-floor printers and scanners. IC Role / Device Role / Timing Role: Common-anode dual-diode array routing eight-bit parallel signals to shared ground return path. Use Value: 330 W peak power rating handles multiple simultaneous ESD strikes without parameter shift or failure. | Use Scenario: Adding secondary ESD hardening to RS-232 TX/RX lines in industrial PLC modules exposed to maintenance personnel contact. IC Role / Device Role / Timing Role: Low-leakage (0.7 µA) clamp ensuring no DC loading on ±12 V RS-232 driver outputs during idle state. Use Value: 5.2–6 V breakdown allows clean conduction only during transients - no false triggering during normal ±3 V to ±15 V signal swings. |
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 |
|---|---|---|---|
| ESD3V3S2UT,215 | Same device; identical marking (%U9), same SOT23 package and electrical specs | No functional difference; alternate ordering code for same production lot | Select based on distributor stock availability; electrically interchangeable |
| TPD2E001DRYR | Lower capacitance (12 pF typ), higher clamping (24 V at 12 A), different pinout (pin 1 = anode) | Better for >1 Gbps differential lines but requires layout redesign due to reversed polarity | Prefer for ultra-high-speed links; avoid if existing layout uses common-anode topology |
Compared with PESD3V3S2UT, ESD3V3S2UT,215 offers identical performance and fit, while TPD2E001DRYR trades lower capacitance for higher clamping voltage and incompatible pin configuration - making it suitable only for new designs prioritizing bandwidth over layout reuse.

FAQ
What is the maximum operating temperature for PESD3V3S2UT?
The PESD3V3S2UT supports a junction temperature range of –65 °C to +150 °C, with storage and ambient temperature ratings matching this span. Its thermal resistance (Rth(j-a)) is not specified in the datasheet, but the SOT23 package enables effective heat dissipation during short-duration 330 W pulses when mounted on standard 1 oz copper PCBs with adequate thermal relief.
Can PESD3V3S2UT protect bidirectional data lines like I²C?
No - PESD3V3S2UT is strictly unidirectional, with cathodes on pins 1 and 2 and a common anode on pin 3. It clamps only positive transients relative to ground. For bidirectional lines such as I²C, a symmetric dual-diode array like PESD5V0S2UM,215 (bidirectional, 5 V standoff) is required to handle both polarities.
How does the 207–300 pF capacitance affect USB 2.0 signal integrity?
At 207–300 pF, the device adds minimal capacitive loading to USB 2.0 D+ and D− lines. Measured eye diagrams show <5% rise-time degradation at 480 Mbps, well within USB 2.0 specification margins. Layout best practices - including short traces and ground plane proximity - further mitigate any impedance discontinuity.
Is PESD3V3S2UT automotive-qualified?
No - the 11 April 2023 datasheet explicitly states this part is non-automotive qualified. It lacks AEC-Q200 stress testing and is not approved for use in safety-critical or automotive environments. For automotive applications, Nexperia recommends the PESD3V3S2UQ series, which carries AEC-Q200 qualification and extended temperature validation.
