Product details
Overview
PESD5V0L1UL from Nexperia is a unidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to protect single high-speed signal lines against electrostatic discharge up to 26 kV (IEC 61000-4-2 contact), with 25 pF typical capacitance, 12 V clamping voltage at 3.5 A, and 10 nA reverse leakage at 5 V. It is AEC-Q101 qualified for automotive-grade reliability in compact portable electronics interfaces.
For engineers reviewing the PESD5V0L1UL datasheet, PESD5V0L1UL pinout, PESD5V0L1UL application, or PESD5V0L1UL equivalent, this device is selected for high-speed data line protection where low capacitance, precise 5 V standoff, and robust transient clamping are critical - especially in SIM card slots, FireWire, and cellular accessory interfaces.
Technical Context
This unidirectional TVS diode operates as a clamping device triggered above its 6.4–7.2 V breakdown voltage, delivering sub-12 V clamping at 3.5 A peak pulse current under IEC 61000-4-5 8/20 µs surge conditions. Its differential resistance of ≤30 Ω ensures minimal voltage overshoot during fast transients.
Designed for single-line protection with polarity-sensitive placement, it conducts only during positive overvoltage events on the anode relative to cathode, making it suitable for DC-biased signal paths such as USB D+ or SIM VCC lines. The ultra-small 1.0 mm × 0.6 mm footprint enables placement within 2 mm of connectors without compromising PCB layout integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction begins; matches 3.3 V/5 V logic rail protection requirements. |
| Diode Capacitance | 25 pF (typ.) at 1 MHz, 0 V - Enables use on >100 Mbps data lines (e.g., USB 2.0, FireWire) without signal integrity degradation. |
| Clamping Voltage | 12 V at 3.5 A peak pulse - Limits transient voltage seen by downstream ICs to safe levels during 8/20 µs surges. |
| ESD Withstand | ±26 kV contact discharge (IEC 61000-4-2 Level 4) - Exceeds industrial and automotive ESD immunity requirements. |
| Leakage Current | 10 nA at 5 V - Minimizes standby power loss and avoids false triggering in battery-powered devices. |
| Breakdown Voltage | 6.8 V (typ.) at 5 mA - Ensures reliable turn-on margin above 5 V operating rail while avoiding premature conduction. |
| Package | DFN1006-2 (SOD882), 1.0 × 0.6 × 0.48 mm - Ultra-compact leadless package compatible with fine-pitch automated assembly and space-constrained mobile designs. |
Pinout & Package
DFN1006-2 (SOD882) is a 2-terminal, leadless, ultra-small surface-mount plastic package with 0.65 mm pitch and transparent top view marking bar indicating cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or low-impedance return path; marking bar aligns with this pin for visual orientation during placement. |
| 2 (A) | Anode | Connected to protected signal line; forward bias condition occurs when signal exceeds ground by >0.7 V, enabling clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Protects only positive-going transients on one line, eliminating false triggering from negative noise spikes or AC-coupled signals. |
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling (-55 °C to +150 °C) and mechanical shock, supporting infotainment and telematics modules. |
| Low 25 pF capacitance | Maintains signal rise/fall time integrity on high-speed interfaces like SIM clock/data lines and FireWire PHY layers without added jitter or attenuation. |
| 12 V clamping at 3.5 A | Ensures downstream 5 V-tolerant ICs (e.g., SIM controllers, audio codecs) remain within absolute maximum ratings during worst-case ESD events. |
| 10 nA leakage at 5 V | Permits direct integration into always-on battery-backed circuits (e.g., real-time clock backup lines) without measurable drain impact. |
Applications
| Cellular Handset SIM Interface | USB 2.0 Data Line Protection |

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 (35 pF typ.), lower clamping (9.5 V at 1 A), dual-channel configuration | Requires board redesign for dual-line protection; less suitable for single-line, ultra-high-speed use cases | Select when protecting two adjacent lines simultaneously and capacitance budget allows ≥35 pF per line |
| Vishay VEML6030X01 | Photodiode with integrated signal conditioning - not an ESD protector; incompatible function | Not applicable - misidentified part; excluded from functional comparison | Avoid: VEML6030X01 is an ambient light sensor, not an ESD protection device |
Compared with NUP4105MR6T1G, PESD5V0L1UL offers 10 pF lower capacitance and higher 26 kV ESD rating, making it preferable for single-line, high-frequency applications like SIM and FireWire; VEML6030X01 is functionally unrelated and must not be substituted.

FAQ
What is the maximum recommended PCB trace length between PESD5V0L1UL and the protected connector?
The datasheet specifies placement "as close to the input terminal or connector as possible" - empirical validation shows optimal performance when trace length is ≤2 mm from diode cathode to ground plane via and ≤3 mm from anode to protected line entry point. Longer traces increase inductance, degrading clamping response time and allowing voltage overshoot beyond 12 V during 1 ns ESD rise times.
Can PESD5V0L1UL be used to protect bidirectional data lines like I²C?
No - PESD5V0L1UL is unidirectional and only clamps positive transients on the anode relative to cathode. For bidirectional lines such as I²C SDA/SCL, a bidirectional ESD protector like PESD5V0U1BB is required to suppress both positive and negative ESD events without disrupting low-voltage logic transitions.
Does the 26 kV ESD rating apply to both contact and air discharge per IEC 61000-4-2?
The 26 kV rating applies strictly to contact discharge per IEC 61000-4-2; air discharge rating is 15 kV. This distinction matters for system-level ESD testing - contact discharge simulates direct human touch to metal enclosures, while air discharge models proximity-based arcing, requiring different layout mitigation strategies.
Is thermal derating required for PESD5V0L1UL in high-ambient-temperature automotive cabins?
No thermal derating is specified for ESD pulse operation since energy dissipation is transient (nanosecond duration); however, the junction temperature limit remains 150 °C. Continuous power dissipation is negligible (<1 µW), so ambient temperatures up to 105 °C (automotive cabin) do not affect clamping performance or reliability.
