Product details
Overview
PESD5V0L1USF from Nexperia is a low-capacitance unidirectional ESD protection diode in a DSN0603-2 (SOD962) package, designed to protect single signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 12 pF typical capacitance, 5 V reverse standoff voltage, and 10.5 V clamping voltage at 1 A. It is used in high-speed data interfaces of portable electronics where signal integrity and transient immunity are critical.
For engineers reviewing the PESD5V0L1USF datasheet, PESD5V0L1USF pinout, PESD5V0L1USF application, or PESD5V0L1USF equivalent, key selection criteria include diode capacitance under 15 pF, clamping performance below 11 V at 1 A, ultra-low leakage (<1 µA), and compatibility with 0.4 mm pitch SMD layouts for USB, HDMI, and audio line protection.
Technical Context
This unidirectional TVS diode operates as a clamping device between signal and ground, conducting only when reverse voltage exceeds 6 V (typical breakdown). Its low dynamic resistance (1.2 Ω) ensures rapid energy diversion during sub-nanosecond ESD events.
The device complies with IEC 61000-4-2 (±30 kV contact/air) and IEC 61643-321 (1.2 A surge), delivering 11 W peak pulse power at 25 °C while maintaining <1 nA reverse leakage at 5 V. Thermal derating follows a defined curve down to zero power at 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; sets upper limit for protected signal swing. |
| Clamping Voltage | 10.5 V at 1 A - Peak voltage seen by downstream circuitry during IEC 61000-4-2 ESD event; defines protection margin. |
| Diode Capacitance | 12 pF at 1 MHz, 0 V - Minimal loading on high-speed lines (e.g., USB 2.0, audio DAC outputs); preserves signal rise time. |
| ESD Withstand | ±30 kV contact discharge - Meets highest IEC 61000-4-2 immunity class without degradation after ten pulses. |
| Peak Pulse Current | 1.2 A (8/20 µs) - Sustains surge transients per IEC 61643-321 without failure; supports system-level surge robustness. |
| Reverse Leakage | 1 µA at 5 V - Negligible DC loading on bias-sensitive circuits (e.g., microphone bias rails, sensor references). |
Pinout & Package
Encapsulated in a leadless DSN0603-2 (SOD962) surface-mount package measuring 0.6 × 0.3 × 0.3 mm with 0.4 mm terminal pitch. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground; carries transient current during ESD clamping; marking bar identifies this terminal. |
| 2 | Anode (A) | Connected to protected signal line; reverse-biased during normal operation; conducts to ground when ESD exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| Low signal-line capacitance | 12 pF typical - Enables use on >100 Mbps digital interfaces without measurable jitter or attenuation. |
| Ultra-low leakage current | <1 µA at 5 V - Prevents DC offset drift in precision analog paths such as audio preamps and sensor front-ends. |
| High ESD immunity | ±30 kV contact per IEC 61000-4-2 - Eliminates need for secondary protection layers in consumer handheld designs. |
| Miniaturized footprint | DSN0603-2 (0.6 × 0.3 mm) - Fits within tight board space constraints near USB-C, micro-HDMI, and SIM card connectors. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against user-handling ESD. IC Role / Device Role: Unidirectional clamping diode placed between signal and chassis ground, with cathode grounded. Use Value: Maintains 480 Mbps signaling integrity while suppressing ±30 kV discharges before they reach the USB transceiver IC. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) pin from ESD during cable insertion/removal. IC Role / Device Role: Standoff protection element referenced to 5 V supply rail, blocking transients from reaching the HDMI controller GPIO. Use Value: Prevents false plug/unplug detection and firmware lockup caused by ESD-induced voltage spikes on the 5 V-tolerant HPD line. |
| Smartphone Audio Jack | Bluetooth Headset MIC Bias |
Use Scenario: Shielding TRRS audio jack tip/ring contacts from ESD during headphone insertion in mobile handsets. IC Role / Device Role: Signal-line protector on left/right audio channels and microphone input, each with dedicated cathode-to-ground path. Use Value: Ensures no pop/noise artifacts or ADC saturation during ESD events, preserving audio fidelity and voice call reliability. | Use Scenario: Protecting electret microphone bias line in compact Bluetooth earbuds from handling ESD. IC Role / Device Role: Low-leakage clamp on 2.1 V MIC bias rail, placed adjacent to mic capsule to minimize trace inductance. Use Value: Avoids DC bias shift or amplifier latch-up while sustaining full IEC 61000-4-2 compliance in space-constrained wearable form factors. |
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 capacitance (22 pF), higher clamping (14 V at 1 A), same 5 V VRWM and SOD-923 package. | Less suitable for >480 Mbps interfaces; better for lower-speed UART or I²C where clamping margin is prioritized over bandwidth. | Select when board layout allows larger capacitance and system tolerates higher clamped voltage. |
| Vishay VEML6030X01 | Not applicable - VEML6030X01 is an ambient light sensor, not an ESD diode; invalid alternative. | N/A | Discard - misidentified part; verify manufacturer and function before substitution. |
Compared with NUP4105MR6T1G, PESD5V0L1USF offers 45 % lower capacitance and 3.5 V lower clamping, making it superior for high-speed signal lines; the Vishay part is functionally incompatible and must be excluded from ESD protection consideration.

FAQ
What is the maximum operating temperature for PESD5V0L1USF?
The absolute maximum junction temperature is 150 °C, with ambient operating range from −55 °C to +150 °C. Derating of peak pulse power begins above 25 °C, dropping to zero at 150 °C per Figure 3 in the datasheet. PCB thermal design must ensure junction temperature remains within this limit during surge events.
Can PESD5V0L1USF protect bidirectional signal lines?
No - PESD5V0L1USF is unidirectional and protects only signals referenced to ground with defined polarity (e.g., positive-only or negative-only swing). For bidirectional lines like USB D+/D− differential pairs, two devices are required per line or a dedicated bidirectional variant such as PESD5V0S1USF must be used.
Is the DSN0603-2 package compatible with standard reflow profiles?
Yes - the device is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. Recommended stencil thickness is 0.1 mm, and solder land dimensions are specified in Figure 11 of the datasheet to ensure reliable void-free joints in high-volume assembly.
How does the 12 pF capacitance impact a 480 Mbps USB 2.0 signal?
At 12 pF, insertion loss at 240 MHz (USB 2.0 fundamental) is <0.3 dB and eye diagram jitter increase is <1 %, verified via TDR simulations in Nexperia's application note AN10780. This meets USB-IF signal integrity requirements without requiring equalization or layout compensation.
