Product details
Overview
PESD2IVN27U-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 ±30 kV IEC 61000-4-2 and ISO 10605 transients. It features 27 V reverse stand-off voltage, 36 V clamping at 3 A, <1 nA leakage, and AEC-Q101 qualification - deployed on CAN, LIN, FlexRay, and SENT bus interfaces.
For engineers reviewing the PESD2IVN27U-QX datasheet, PESD2IVN27U-QX pinout, PESD2IVN27U-QX application, or PESD2IVN27U-QX equivalent, key selection criteria include bidirectional clamping performance under 8/20 µs surge, ultra-low capacitance (14–17 pF), common-cathode dual-diode topology, and automotive thermal robustness up to 150 °C junction temperature.
Technical Context
This device implements a dual unidirectional TVS diode configuration with shared cathode (Pin 3), enabling independent protection of two signal lines while minimizing PCB footprint. Its low dynamic resistance (0.2 Ω) and fast response (<1 ns rise time per IEC 61000-4-2) ensure effective transient energy diversion before downstream ICs are stressed.
The 27 V VRWM aligns with 24 V automotive supply rails and 12 V CAN/LIN nominal voltages, while clamping at 36 V (typ.) under 3 A 8/20 µs pulse prevents overvoltage damage to transceivers. Diode capacitance remains stable (14–17 pF at 0 V) to preserve high-speed bus signal integrity on CAN FD and SENT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 27 V - Ensures no conduction during normal 24 V automotive bus operation, avoiding false triggering. |
| Clamping Voltage | 36 V (typ.) at 3 A, 8/20 µs - Limits transient voltage seen by protected transceiver to safe level below absolute maximum ratings. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2 & ISO 10605) - Meets stringent automotive ESD immunity requirements for exposed connectors. |
| Diode Capacitance | 14–17 pF at 0 V, 1 MHz - Low enough to avoid signal distortion on CAN (up to 1 Mbps) and SENT (up to 125 kbps) buses. |
| Leakage Current | <1 nA at 27 V - Prevents measurable DC loading on high-impedance bus lines, preserving bias and termination integrity. |
| Peak Pulse Current | 3 A, 8/20 µs - Supports ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) surge immunity without degradation. |
| Junction Temperature | −55 °C to +150 °C - Enables operation in under-hood and infotainment modules across full automotive ambient range. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 × 1.25 × 0.95 mm body. Optimized for automated placement and reflow soldering per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line (e.g., CANH); anode tied internally to Pin 3 for unidirectional clamping to ground. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line (e.g., CANL); enables independent protection of dual bus signals with shared return path. |
| 3 | K (common cathode) | Ground reference terminal; must be connected to low-inductance chassis or system ground plane for effective transient shunting. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single SC-70 package | Reduces PCB area by >40% vs. discrete dual-diode solutions; eliminates routing asymmetry between protected lines. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HTRB, and ESD stress - supports PPAP documentation for Tier-1 suppliers. |
| Ultra-low leakage current | <1 nA ensures negligible impact on bus bias networks and failsafe monitoring circuits in LIN and SENT receivers. |
| Low dynamic resistance | 0.2 Ω (TLP measured) enables rapid voltage clamping with minimal overshoot during sub-ns ESD events. |
| Stable capacitance vs. voltage | 14–17 pF across 0–27 V reverse bias - maintains consistent signal rise/fall times and impedance matching on differential buses. |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
|
Use Scenario: ESD protection at OBD-II connector interface on engine control unit (ECU) CANH/CANL lines. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector entry point, clamping fast ESD pulses before reaching CAN transceiver. Use Value: Prevents latch-up or permanent damage to TJA1042/TJA1051 transceivers during service port handling, maintaining CAN communication integrity. |
Use Scenario: Protection of LIN slave node (e.g., door module actuator) against ESD during assembly and field maintenance. IC Role / Device Role / Timing Role: Unidirectional clamp on LIN bus line referenced to vehicle ground, suppressing ±30 kV contact discharges. Use Value: Eliminates need for external RC filters while preserving LIN's 19.2 kbps timing budget and DC bias stability. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
|
Use Scenario: Front radar module FlexRay A/B channel input protection in ADAS domain controller. IC Role / Device Role / Timing Role: Dual-channel protector isolating both FlexRay differential pairs from ESD-induced common-mode surges. Use Value: Maintains FlexRay's 10 Mbps data rate and <100 ps skew tolerance via low-capacitance, matched-path design. |
Use Scenario: Protection of pressure sensor SENT output line in brake-by-wire system. IC Role / Device Role / Timing Role: Clamping device on single-ended SENT signal (0–5 V), referenced to chassis ground near sensor connector. Use Value: Preserves SENT's precise pulse-width modulation timing (±100 ns accuracy) with sub-pF parasitic contribution. |
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 |
|---|---|---|---|
| Infineon ESD204-B1-W02 | 24 V VRWM, 30 V clamping at 3 A, 12 pF capacitance, same SOT323 package | Better suited for 12 V systems; lower clamping may benefit low-voltage transceivers but risks false triggering on 24 V buses | Select when protecting 12 V LIN/Sent nodes where tighter clamping margin is required and 24 V compatibility is not needed. |
| ON Semiconductor NUF2042MUTAG | 24 V VRWM, 33 V clamping at 3 A, 15 pF, AEC-Q101 qualified, SOT-563 (6-pin) | Larger footprint; includes integrated 100 Ω series resistors for EFT filtering - adds propagation delay unsuitable for high-speed CAN FD | Choose only when combined ESD + EFT filtering is mandatory and board space allows larger package; avoid for CAN FD or SENT. |
Compared with ESD204-B1-W02 and NUF2042MUTAG, PESD2IVN27U-QX offers optimal balance of 27 V standoff for 24 V systems, 36 V clamping headroom, and minimal 14–17 pF capacitance - making it the preferred choice for CAN, FlexRay, and SENT where signal integrity and automotive voltage compliance are co-critical.

FAQ
What is the maximum peak pulse current rating for PESD2IVN27U-QX?
The rated peak pulse current is 3 A under 8/20 µs exponential waveform per IEC 61000-4-5. This rating applies to both pins 1 and 2 referenced to pin 3, and is validated per ISO 7637-3 Pulse a (−150 V) and Pulse b (+100 V) test conditions.
Can PESD2IVN27U-QX be used for bidirectional signal lines like RS-485?
No - PESD2IVN27U-QX uses a dual unidirectional configuration with common cathode (Pin 3), meaning each channel clamps only positive transients to ground. It is not suitable for true bidirectional buses requiring symmetrical ± clamping unless paired with additional components.
Is the 30 kV ESD rating applicable to both contact and air discharge?
The 30 kV rating is specified for contact discharge per IEC 61000-4-2 and ISO 10605 (C = 330 pF, R = 330 Ω). Air discharge rating is not published in the datasheet and should not be assumed equal; design margins must rely on verified contact discharge performance.
How does the common-cathode architecture affect PCB layout?
The shared cathode (Pin 3) requires a low-inductance ground connection - ideally a dedicated ground pour with multiple vias to inner-layer ground plane. Signal traces from Pins 1 and 2 to protected lines must be symmetrical and as short as possible (<5 mm) to prevent impedance mismatch and ensure balanced clamping.
