Product details
Overview
PESD3V3S1UL-Q from Nexperia is a unidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to protect single signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 3.3 V reverse standoff voltage, 207–300 pF capacitance, and 20 V clamping voltage at 15 A surge. It is qualified to AEC-Q101 for automotive signal line protection.
For engineers reviewing the PESD3V3S1UL-Q datasheet, PESD3V3S1UL-Q pinout, PESD3V3S1UL-Q application, or PESD3V3S1UL-Q equivalent, key selection criteria include low clamping voltage under 15 A surge, sub-1 µA leakage at 3.3 V, ultra-small 1.0 mm × 0.6 mm footprint, and AEC-Q101 qualification for harsh-environment deployment.
Technical Context
This device operates as a unidirectional transient voltage suppressor, leveraging avalanche breakdown above 5.2 V (typ. 5.6 V) to clamp transients while maintaining ≤3.3 V reverse standoff during normal operation. Its low 207–300 pF capacitance ensures minimal signal integrity impact on high-speed data lines up to ~100 MHz.
The diode exhibits 400 Ω differential resistance at 1 mA forward bias and delivers 150 W peak pulse power (8/20 µs waveform) with thermal derating to 50% at 150 °C junction temperature. It meets IEC 61000-4-5 surge (15 A) and IEC 61000-4-2 ESD (±30 kV contact) requirements without external biasing.
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, preserving signal integrity. |
| Clamping Voltage | 20 V at 15 A - Limits transient voltage to safe levels for downstream 3.3 V ICs during IEC 61000-4-5 surges. |
| Diode Capacitance | 207–300 pF at 1 MHz - Compatible with USB 2.0, HDMI, and audio interfaces without excessive signal attenuation. |
| Peak Pulse Power | 150 W (8/20 µs) - Sustains high-energy transients without failure in automotive and industrial environments. |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 level 4 - Protects exposed connectors against human-body ESD events. |
| Leakage Current | 0.7 µA typ. at 3.3 V - Minimizes standby power loss and avoids false triggering in low-power sensor nodes. |
| Package Dimensions | 1.0 mm × 0.6 mm × 0.48 mm - Enables placement directly at board edge connectors with minimal PCB area usage. |
Pinout & Package
DFN1006-2 (SOD882) leadless ultra-small surface-mount package: 2-terminal, 0.65 mm pitch, 1.0 mm × 0.6 mm body size, 0.48 mm height. Cathode indicated by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected signal line; clamps positive transients to ground when voltage exceeds breakdown threshold. |
| 2 | Anode (A) | Connected to system ground; completes current path during ESD/surge events, enabling low-impedance discharge. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 207–300 pF enables use on high-speed interfaces (e.g., USB 2.0, HDMI, MIPI) without signal distortion. |
| AEC-Q101 qualification | Validated for automotive applications including infotainment and ADAS sensor interfaces under extended temperature and reliability stress. |
| Low clamping voltage | 20 V at 15 A limits voltage overshoot to protect 3.3 V I/O pins of microcontrollers and transceivers. |
| Sub-micron leakage | 0.7 µA typical reverse leakage preserves battery life in always-on portable and telematics modules. |
Applications
| USB 2.0 Data Lines | Automotive Infotainment Ports |
|---|---|
Use Scenario: Protection of D+ and D− lines on USB 2.0 host/device connectors exposed to user-handled cables. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed immediately adjacent to connector to shunt ESD before reaching USB PHY. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while maintaining <300 pF loading for full-speed 480 Mbps signaling. | Use Scenario: Signal line protection for HDMI or LVDS video inputs on head unit displays and rear-seat entertainment systems. IC Role / Device Role / Timing Role: Single-line ESD suppressor on differential video pairs, grounded anode configuration for common-mode transient suppression. Use Value: Maintains signal fidelity across 1080p/60 Hz video streams while surviving ±30 kV ESD events per AEC-Q101 requirements. |
| Audio Line Inputs | Industrial Sensor Interfaces |
Use Scenario: Protection of analog audio input jacks (e.g., 3.5 mm TRS) in automotive head units and consumer AV receivers. IC Role / Device Role / Timing Role: Unidirectional clamp on biased audio lines where signal swings positive relative to ground. Use Value: Adds <0.7 µA leakage and <300 pF capacitance-negligible impact on 20 Hz–20 kHz frequency response and SNR. | Use Scenario: Protection of RS-485 or CAN FD data lines in vehicle body control modules and gateway ECUs. IC Role / Device Role / Timing Role: Point-of-entry transient suppressor on bidirectional communication lines using separate unidirectional devices per polarity. Use Value: Withstands 15 A IEC 61000-4-5 surges and ±30 kV ESD without degradation, ensuring bus uptime in electrically noisy chassis environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher 350 pF capacitance; 24 V clamping at 12 A; not AEC-Q101 qualified. | Suitable for industrial non-automotive USB/audio but lacks automotive reliability validation. | Select when cost sensitivity outweighs AEC-Q101 requirement and higher capacitance is acceptable. |
| Vishay VEML3020-001 | Lower 150 pF capacitance; 18 V clamping at 12 A; AEC-Q101 qualified; 3.3 V VRWM same. | Better for >100 MHz interfaces but rated only to 12 A surge (vs. 15 A here). | Prefer for RF-sensitive applications like GNSS antenna lines where <200 pF is critical. |
Compared with NUP4105MR6T1G and VEML3020-001, PESD3V3S1UL-Q uniquely balances AEC-Q101 compliance, 15 A surge rating, and 207–300 pF capacitance-making it optimal for automotive USB/HDMI interfaces requiring both robustness and signal fidelity.

FAQ
What is the maximum operating temperature for PESD3V3S1UL-Q?
The device supports continuous operation up to +150 °C junction temperature and ambient temperatures from –55 °C to +150 °C. Thermal derating reduces peak pulse power to 50% at 150 °C, as confirmed in Figure 4 of the datasheet. This enables use in engine bay and powertrain proximity applications.
Can PESD3V3S1UL-Q protect bidirectional signal lines?
No-it is strictly unidirectional and protects only signals with defined polarity relative to ground. For bidirectional lines (e.g., USB D+/D−, RS-485), two devices must be used back-to-back or a dedicated bidirectional ESD diode selected. The cathode marking bar and pin 1 designation confirm its single-polarity architecture.
Is solder reflow profile information available for this package?
Yes-the recommended reflow footprint and stencil design for DFN1006-2 are specified in Figure 11 of the datasheet, with 0.3 mm solder paste thickness and 0.9 mm × 0.3 mm pad dimensions. Peak reflow temperature must not exceed 260 °C per JEDEC J-STD-020 for this MSL1-rated package.
Does PESD3V3S1UL-Q require external biasing or control circuitry?
No-it is a passive, two-terminal device requiring no external power, bias, or control. It operates automatically via avalanche breakdown when transient voltage exceeds 5.2 V, clamping within nanoseconds. No enable/disable pins, timing circuits, or supporting components are needed.
