Product details
Overview
PESD2IVN24U-QX 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 - deployed on CAN, LIN, FlexRay, and SENT bus interfaces.
For engineers reviewing the PESD2IVN24U-QX datasheet, PESD2IVN24U-QX pinout, PESD2IVN24U-QX application, or PESD2IVN24U-QX equivalent, this device delivers validated AEC-Q101 qualification, ultra-low capacitance (14–17 pF), and bidirectional clamping for high-speed automotive serial buses requiring robust transient immunity without signal integrity degradation.
Technical Context
This dual-cathode TVS diode implements a common-cathode configuration (pins 1 & 2 as individual cathodes, pin 3 as shared cathode), enabling independent protection of two differential or single-ended IVN lines while maintaining low dynamic resistance (0.16 Ω typical per channel under TLP stress). Its design targets fast transient response (<1 ns rise time) and minimal parasitic capacitance to preserve signal integrity on 1–10 Mbps bus protocols.
The device operates within −55 °C to +150 °C ambient range and supports ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) surge immunity. Junction temperature is rated up to 150 °C, and its 8/20 μs pulse handling (3.5 A) aligns with IEC 61000-4-5 Level 3 requirements for automotive electronics subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 24 V - Ensures no conduction during normal 24 V automotive supply rail operation; defines maximum continuous working voltage before leakage increases. |
| Clamping Voltage (VCL) | 33 V (typ.) at 3.5 A - Limits transient voltage seen by downstream transceiver ICs during ESD strike, staying well below typical CAN/LIN IC absolute max ratings (±40 V). |
| ESD Withstand | ±30 kV per IEC 61000-4-2 (contact) and ISO 10605 (330 pF/330 Ω) - Meets stringent automotive ESD immunity requirements for exterior connectors and exposed harnesses. |
| Diode Capacitance (Cd) | 14–17 pF at 0 V - Low enough to avoid signal distortion on CAN FD (up to 5 Mbps) and SENT (up to 125 kbps) without degrading edge rates or causing reflections. |
| Leakage Current (IRM) | 1 nA (typ.) at 24 V - Prevents measurable DC loading on high-impedance bus bias networks and avoids false wake-up in low-power sleep modes. |
| Dynamic Resistance (Rdyn) | 0.16 Ω (typ., TLP 100 ns) - Enables rapid voltage clamping with minimal IR drop, critical for preserving waveform fidelity during sub-100 ns ESD pulses. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 × 1.25 × 0.95 mm body size; optimized for automated placement and reflow soldering on dense automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line (e.g., CANH); forms cathode-side clamp path to common ground reference via pin 3. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line (e.g., CANL); enables independent clamping of each line to shared cathode node. |
| 3 | K (common cathode) | Must be connected directly to low-inductance chassis or system ground plane; serves as unified return path for both ESD current paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress - ensures reliability across 15-year vehicle lifetimes and extreme thermal environments. |
| Bidirectional clamping | Protects both positive and negative transients on each line without polarity constraints - essential for differential buses like CAN where both lines swing above/below ground. |
| Ultra-low leakage (1 nA) | Eliminates measurable current draw in always-on bus monitoring circuits, preventing battery drain in parked vehicle scenarios. |
| Low 14–17 pF capacitance | Maintains signal rise/fall times <10 ns on 125 kbps SENT and <20 ns on 1 Mbps CAN, avoiding bit errors or timing jitter. |
| Common-cathode dual-diode topology | Reduces PCB footprint vs. two discrete diodes; simplifies layout with single ground connection and matched clamping thresholds for differential pair protection. |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface on engine control unit (ECU) PCB. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between CANH/CANL pins and transceiver IC, clamping ESD energy before it reaches PHY layer. Use Value: Prevents latch-up or permanent damage to CAN transceivers during service technician contact, maintaining communication integrity after ±8 kV contact discharge. |
Use Scenario: Protection of LIN slave node (e.g., door module) wiring harness entry point. IC Role / Device Role / Timing Role: Bidirectional shunt clamp on LIN bus line, referenced to local ground plane near connector. Use Value: Enables reliable 19.2 kbps LIN communication in humid, high-vibration environments where static buildup exceeds 15 kV. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Front radar module interface where FlexRay bus connects to ADAS domain controller. IC Role / Device Role / Timing Role: High-speed transient suppressor on FlexRay A/B differential pair, minimizing added capacitance. Use Value: Preserves 10 Mbps FlexRay signal integrity while surviving repeated ±25 kV ESD events during assembly and field maintenance. |
Use Scenario: Pressure sensor output line in powertrain control module, exposed to engine bay ESD sources. IC Role / Device Role / Timing Role: Single-line unidirectional clamp on SENT data line, referenced to sensor ground. Use Value: Blocks ESD-induced glitches that cause erroneous pulse-width decoding, ensuring accurate 12-bit pressure reporting over 125 kbps SENT. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Single-package quad-channel (not dual); VRWM = 5 V; higher Cd = 30 pF; lower VCL = 12 V at 1 A. | Targeted at 5 V logic-level interfaces (e.g., USB, I²C), not 24 V IVN buses; unsuitable for CAN/FlexRay due to voltage mismatch and excessive capacitance. | Select only for low-voltage, non-automotive digital I/O protection - not a functional substitute for PESD2IVN24U-QX in IVN systems. |
| Vishay ESDFUSE03-2 | Integrated polyfuse + ESD diode; VRWM = 3.3 V; VCL = 14 V at 1 A; includes overcurrent protection. | Designed for USB Type-C and HDMI hot-plug protection; lacks AEC-Q101 qualification and 24 V standoff capability. | Use when combined overcurrent + ESD protection is required at ≤5 V; reject for automotive IVN due to voltage rating and qualification gap. |
Compared with NUP4105MR6T1G and ESDFUSE03-2, PESD2IVN24U-QX uniquely satisfies 24 V IVN operating voltage, AEC-Q101 qualification, and sub-17 pF capacitance - making it the only viable option among the three for CAN, LIN, FlexRay, and SENT bus protection in production automotive ECUs.

FAQ
What is the maximum peak pulse current the PESD2IVN24U-QX can handle?
The device is rated for 3.5 A peak pulse current (IPPM) under 8/20 μs exponential waveform per IEC 61000-4-5. This value is confirmed in Table 1 and Table 5 of the official Nexperia datasheet dated 7 March 2024, and applies to stress applied from either pin 1 or pin 2 to pin 3.
Is PESD2IVN24U-QX compatible with lead-free reflow soldering processes?
Yes - the SOT323 package is qualified for standard lead-free reflow profiles, including JEDEC J-STD-020-compliant peak temperatures up to 260 °C. Figure 14 in the datasheet provides the recommended reflow soldering footprint with 0.55 mm solder paste stencil openings for all three pads.
Can PESD2IVN24U-QX protect both CANH and CANL simultaneously in a differential pair?
Yes - its common-cathode dual-diode architecture allows independent clamping of CANH (pin 1 → pin 3) and CANL (pin 2 → pin 3) to the same ground reference. This maintains differential mode integrity while suppressing common-mode ESD transients, as shown in Figure 12 of the datasheet.
Does the 1 nA leakage current specification apply across the full operating temperature range?
No - the 1 nA value is typical at Tamb = 25 °C and VRWM = 24 V. At maximum junction temperature (150 °C), leakage rises to ≤50 nA per Table 6, which remains negligible for IVN bias networks and does not compromise low-power sleep functionality.
