Product details
Overview
PESD1IVN24A-QX from Nexperia is a bidirectional automotive-grade ESD protection diode in SOD323 package, designed for in-vehicle network (IVN) bus lines. It provides 24 V reverse standoff voltage, 33 V clamping at 3.5 A peak pulse current, and 30 kV IEC 61000-4-2/ISO 10605 ESD immunity-used to safeguard CAN, LIN, FlexRay, and SENT transceivers against transient overvoltage.
For engineers reviewing the PESD1IVN24A-QX datasheet, PESD1IVN24A-QX pinout, PESD1IVN24A-QX application, or PESD1IVN24A-QX equivalent, key selection criteria include clamping performance under 8/20 µs surge, ultra-low leakage (<1 nA), diode capacitance (14–17 pF), AEC-Q101 qualification, and dual-cathode configuration for bidirectional IVN line protection.
Technical Context
This device implements a dual-cathode, bidirectional TVS diode architecture optimized for low-capacitance, high-speed automotive serial buses. Its VRWM = 24 V aligns with 24 V vehicle electrical systems, while dynamic resistance of 0.2 Ω ensures rapid voltage clamping during ESD events.
The SOD323 package supports compact PCB layout near connectors, and its TLP-tested clamping behavior (32 V at 16 A) confirms robust response to fast transients. ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) compliance validates suitability for load-dump and inductive switching environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures stable operation on 24 V IVN buses without leakage conduction during normal signaling. |
| Clamping Voltage | 33 V (typ.) at 3.5 A - Limits transient voltage to safe levels for downstream CAN/LIN transceivers. |
| ESD Rating | ±30 kV (IEC 61000-4-2 & ISO 10605) - Meets stringent automotive ESD immunity requirements. |
| Diode Capacitance | 14–17 pF at 0 V - Minimizes signal distortion on high-speed IVN lines up to 1 Mbps (CAN FD). |
| Leakage Current | <1 nA at 24 V - Prevents DC loading and battery drain in always-on automotive modules. |
| Peak Pulse Current | 3.5 A (8/20 µs) - Handles repetitive surge events per ISO 7637-3 without degradation. |
| Dynamic Resistance | 0.2 Ω - Enables fast voltage clamping response and low power dissipation during transients. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked with bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Diode 1 | Forms one half of bidirectional clamping path; connects to protected IVN line (e.g., LIN bus). |
| 2 (K2) | Cathode of Diode 2 | Completes bidirectional structure; ties to same IVN line, enabling symmetric ±ESD suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables single-device protection of differential or single-ended IVN lines without polarity constraints. |
| AEC-Q101 Qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress-ensures reliability across −55 °C to +150 °C. |
| Ultra-Low Capacitance | 14–17 pF preserves signal integrity on CAN, LIN, and SENT buses operating up to 2 Mbps. |
| Low Clamping Ratio | VCL/VRWM ≈ 1.38 - Delivers tight voltage limiting relative to operating rail, reducing transceiver stress. |
| Compact SOD323 Footprint | Minimizes PCB area and parasitic inductance-critical for effective ESD suppression near connectors. |
Applications
| Automotive CAN Bus Protection | Automotive LIN Bus Protection |
|---|---|
|
Use Scenario: Protecting high-speed CAN FD nodes in engine control units (ECUs) exposed to ESD during service or harness mating. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between CAN_H/CAN_L differential pair and transceiver input pins. Use Value: Clamps ±30 kV ESD pulses to ≤33 V within nanoseconds, preventing transceiver latch-up or permanent damage. |
Use Scenario: Safeguarding LIN slave nodes (e.g., door modules, sensors) connected to vehicle battery and ground via long wiring harnesses. IC Role / Device Role / Timing Role: Single-line ESD protector tied across LIN bus and ground, leveraging dual-cathode symmetry for polarity-agnostic protection. Use Value: Maintains <1 nA leakage to avoid battery drain in sleep-mode modules while suppressing ISO 10605 30 kV contact discharge. |
| FlexRay Communication Node | SENT Sensor Interface |
|
Use Scenario: Shielding FlexRay physical layer transceivers in chassis domain controllers from ESD and load-dump-induced surges. IC Role / Device Role / Timing Role: Line-to-ground TVS diode mounted directly at FlexRay connector, minimizing trace inductance before protection activation. Use Value: 3.5 A 8/20 µs surge rating and 0.2 Ω dynamic resistance ensure sub-10 ns response to fast transients without signal edge degradation. |
Use Scenario: Protecting SENT (Single Edge Nibble Transmission) interfaces in pressure/temperature sensors located in under-hood environments. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on SENT data line, preserving 125 kHz carrier timing and nibble edge fidelity. Use Value: 14–17 pF capacitance avoids signal rise/fall time distortion, enabling reliable 12-bit sensor data transmission over extended harness lengths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC27A | Unidirectional, higher VRWM = 27 V, larger SMC package (7.1 mm × 6.2 mm), 100 pF capacitance | Requires two devices for bidirectional protection; unsuitable for high-speed IVN due to excessive capacitance | Select only for 27 V non-automotive industrial power-line surge where speed is not critical |
| Vishay VMMT3010 | Bidirectional, VRWM = 24 V, but rated only to 15 kV ESD (IEC 61000-4-2), SOT-23 package, 25 pF capacitance | Lacks ISO 10605 30 kV and AEC-Q101 qualification; higher capacitance degrades SENT/CAN signal edges | Acceptable for cost-sensitive non-safety LIN nodes where full automotive qualification is waived |
Compared with SZ1.5SMC27A and VMMT3010, PESD1IVN24A-QX uniquely combines AEC-Q101 qualification, 30 kV bidirectional ESD rating, 14–17 pF capacitance, and SOD323 size-making it the only option qualified for production CAN FD, SENT, and FlexRay nodes requiring zero-compromise transient immunity.

FAQ
Is PESD1IVN24A-QX unidirectional or bidirectional?
PESD1IVN24A-QX is a bidirectional ESD protection diode. Its dual-cathode (K1/K2) configuration enables symmetrical clamping for both positive and negative transients on a single IVN line-no external polarity routing required. This is confirmed by its ±30 kV IEC 61000-4-2 rating and V-I curve symmetry in the datasheet Figure 3.
What is the maximum operating temperature for continuous use?
The device supports continuous operation up to +150 °C junction temperature, validated per AEC-Q101 thermal cycling and high-temperature reverse bias testing. Ambient operating range is −55 °C to +150 °C, with derating applied above 85 °C ambient per Figure 8's PPP(Tj) curve.
Can PESD1IVN24A-QX protect both CAN_H and CAN_L simultaneously?
No-it protects a single line (e.g., CAN_H-to-ground or CAN_L-to-ground). For full differential CAN bus protection, two devices are required: one on CAN_H and one on CAN_L. The datasheet Figure 12 shows single-line LIN protection, and the dual-cathode design is intended for line-to-ground, not line-to-line, clamping.
Does PESD1IVN24A-QX require external series impedance for optimal ESD performance?
No external series resistor is required. The device's low dynamic resistance (0.2 Ω) and optimized SOD323 layout enable direct placement at the connector. However, PCB trace inductance must be minimized-datasheet Section 10 specifies placement within 2 mm of the protected terminal and avoidance of shared return paths to preserve clamping speed.
