Product details
Overview
PESD2IVN24-UX from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 (SC-70) package, designed to safeguard two in-vehicle network lines against IEC 61000-4-2 ±30 kV and ISO 10605 ±30 kV ESD events, with 24 V reverse standoff voltage, 33 V clamping at 3.5 A, and <1 nA leakage current. It protects CAN, LIN, FlexRay, and SENT bus interfaces in harsh automotive environments.
For engineers reviewing the PESD2IVN24-UX datasheet, PESD2IVN24-UX pinout, PESD2IVN24-UX application, or PESD2IVN24-UX equivalent, this device delivers validated bidirectional transient suppression for high-reliability IVN signal lines where low capacitance (14–17 pF), AEC-Q101 qualification, and ultra-low leakage are critical selection criteria.
Technical Context
This dual-cathode TVS diode integrates two independent unidirectional protection paths sharing a common cathode (Pin 3), enabling compact protection of differential bus pairs without requiring separate ground return paths per line. Its architecture supports simultaneous clamping on both protected lines during asymmetric transients.
It operates within −55 °C to +150 °C ambient range and sustains junction temperatures up to 150 °C, meeting automotive thermal stress requirements. The 8/20 μs pulse response (IEC 61000-4-5 compliant) and TLP-characterized dynamic resistance (0.16 Ω typical) ensure predictable energy dissipation under fast-rising surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before conduction; ensures no interference with 24 V nominal IVN bus signaling. |
| Clamping Voltage | 33 V at 3.5 A - Peak voltage seen by protected IC during 8/20 μs surge; limits stress on downstream CAN/LIN transceivers. |
| ESD Withstand | ±30 kV (IEC 61000-4-2 & ISO 10605) - Validated immunity to contact discharge events common in vehicle assembly and service environments. |
| Diode Capacitance | 14–17 pF at 0 V - Low parasitic loading preserves signal integrity on high-speed buses like CAN FD and SENT. |
| Leakage Current | <1 nA at 24 V - Negligible DC load on bus lines, avoiding voltage droop or false wake-up in low-power sleep modes. |
| Dynamic Resistance | 0.16 Ω (TLP, 100 ns) - Enables rapid voltage collapse during ESD, reducing energy delivered to protected ICs. |
| AEC-Q101 Qualified | Yes - Certified for automotive use including temperature cycling, humidity bias, and mechanical shock testing per AEC standard. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package measuring 2.0 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch. Optimized for automated placement and reflow soldering per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Return path for ESD current from first protected line (e.g., CANH); connects to local chassis or dedicated low-inductance ground plane. |
| 2 | K2 (Cathode 2) | Return path for ESD current from second protected line (e.g., CANL); enables independent clamping while sharing common reference. |
| 3 | K (Common Cathode) | Shared cathode node tied to system ground; eliminates need for separate ground traces and reduces PCB loop area for transient return. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single package | Reduces board space by 40% vs. discrete diodes; simplifies layout for differential bus routing near connectors. |
| Ultra-low leakage current | <1 nA ensures no measurable impact on bus bias networks or wake-up sensitivity in always-on IVN nodes. |
| Bidirectional clamping capability | Supports both positive and negative ESD pulses on each line without polarity constraints-critical for unpowered bus states. |
| Low dynamic impedance | 0.16 Ω minimizes clamping overshoot and improves energy diversion efficiency during sub-nanosecond ESD events. |
| Automotive-qualified construction | AEC-Q101 certification confirms reliability across extended temperature, vibration, and humidity profiles required for under-hood deployment. |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: Protecting CANH/CANL lines at ECU connector interface against ESD during vehicle assembly, service, or electromagnetic coupling. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector entry point, clamping surges before reaching CAN transceiver. Use Value: Prevents latch-up or permanent damage to ISO 11898-compliant transceivers while maintaining <17 pF loading for bit rates up to 5 Mbps. |
Use Scenario: Safeguarding LIN master/slave nodes in body control modules from ESD induced via wiring harnesses or diagnostic ports. IC Role / Device Role / Timing Role: Low-leakage protector co-located with LIN transceiver input pins to avoid signal distortion during 19.2 kbps communication. Use Value: Ensures reliable wake-up detection and error-free frame transmission under ±30 kV contact discharge per ISO 10605. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Shielding FlexRay channel A/B differential pairs in powertrain ECUs from ESD and ISO 7637-3 pulse 5a/b transients. IC Role / Device Role / Timing Role: Dual-path clamp aligned with FlexRay physical layer to limit voltage excursion during fault conditions. Use Value: Maintains signal fidelity at 10 Mbps data rate with minimal jitter contribution due to 14–17 pF capacitance and fast turn-on. |
Use Scenario: Securing SENT output lines from pressure, temperature, or position sensors exposed to ESD during engine bay installation. IC Role / Device Role / Timing Role: High-speed transient suppressor placed between sensor output and microcontroller input to preserve pulse-width timing accuracy. Use Value: Clamps transients below 33 V without distorting 12-bit resolution SENT frames, supporting diagnostic and calibration functions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP2114 | Single-channel, 2-pin SOD-323; requires two devices for dual-line protection; VRWM = 24 V, VCL = 36 V @ 3.5 A. | Higher board area and routing complexity; lacks shared-cathode topology for differential pair grounding. | Use only when discrete placement flexibility outweighs space and layout advantages of integrated dual-cathode design. |
| Vishay VEML6040 | Optical sensor IC-not an ESD protector; invalid comparison; excluded from functional equivalence assessment. | N/A - Not applicable as ESD protection device. | Not suitable as alternative; misidentified part; verify part number and function before substitution. |
Compared with NUP2114, PESD2IVN24-UX reduces component count by 50%, lowers ground loop inductance via common cathode, and achieves 3 V lower clamping voltage-directly improving margin for 3.3 V/5 V transceiver survival. VEML6040 is unrelated and must be excluded from ESD protection selection.

FAQ
What is the maximum peak pulse current rating for PESD2IVN24-UX?
The rated peak pulse current (IPPM) is 3.5 A under 8/20 μs exponential waveform per IEC 61000-4-5. This value is measured from Pin 1 or Pin 2 to Pin 3 and defines the maximum transient energy the device can safely divert without degradation. It aligns with ISO 7637-3 Pulse 5a (−150 V) and Pulse 5b (+100 V) test levels.
Does PESD2IVN24-UX support bidirectional ESD protection on both lines simultaneously?
Yes. Each channel (Pin 1→Pin 3 and Pin 2→Pin 3) provides unidirectional clamping, but the dual-cathode configuration allows independent protection of two signal lines against both positive and negative ESD events. The common cathode (Pin 3) serves as the unified low-impedance return path for all transient currents.
How does the 14–17 pF capacitance affect high-speed IVN signals?
This capacitance is measured at 1 MHz and 0 V bias, and remains stable across operating voltage. At CAN FD speeds (up to 5 Mbps) and SENT frame rates, it introduces negligible rise-time degradation or reflection-verified in Nexperia's application note AN11160 for SC-70 ESD protectors in differential bus layouts.
Is PESD2IVN24-UX compatible with lead-free reflow processes?
Yes. The SOT323 package is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C. Recommended footprint dimensions (2.65 mm × 2.35 mm solder lands, 0.55 mm paste stencil) are provided in Figure 14 of the datasheet for optimal wetting and void control.
