Product details
Overview
PESD2CANFD36LU-QX from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 package, designed to safeguard CAN-FD and FlexRay bus lines against 22 kV IEC 61000-4-2 ESD events. It features 36 V reverse standoff voltage, 43 V clamping at 1 A, 10 pF capacitance, and AEC-Q101 qualification for under-hood vehicle networks.
For engineers reviewing the PESD2CANFD36LU-QX datasheet, PESD2CANFD36LU-QX pinout, PESD2CANFD36LU-QX application, or PESD2CANFD36LU-QX equivalent, key selection criteria include bidirectional clamping performance, low capacitance for high-speed bus integrity, common-cathode dual-diode topology, and automotive transient immunity compliance.
Technical Context
This device implements a dual-common-cathode TVS diode architecture with symmetrical breakdown (37–47 V) and matched capacitance (≤0.5% ΔCd/Cd), enabling balanced transient suppression across two independent signal lines referenced to a shared ground return path. Its TLP-measured clamping voltage of 47 V at 16 A ensures robust surge handling per ISO 10605 and IEC 61000-4-5.
The 8.6–10 pF capacitance at 1 MHz and 2.5 V reverse bias preserves signal integrity on CAN-FD buses operating up to 5 Mbps, while the 0.8 Ω dynamic resistance minimizes voltage overshoot during fast ESD transients (tr ≤ 1 ns). Thermal derating follows a defined PPP vs. Tj curve, supporting operation from −55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Ensures no conduction during normal 24 V board net operation with margin against ripple and transients. |
| Clamping Voltage | 47 V at 16 A (TLP) - Limits peak bus-line overvoltage to safe levels for CAN transceivers rated ≤58 V abs max. |
| ESD Rating | ±22 kV contact discharge (IEC 61000-4-2) - Meets automotive OEM requirements for dashboard, gateway, and ADAS module interfaces. |
| Diode Capacitance | 10 pF max at 1 MHz / 2.5 V - Enables <1% signal distortion on 5 Mbps CAN-FD differential pairs with minimal timing skew. |
| Dynamic Resistance | 0.8 Ω - Reduces clamping voltage rise during sub-nanosecond ESD edges, improving protection speed. |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validates reliability for 15-year automotive service life. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 × 1.25 × 0.95 mm body. RoHS-compliant, halogen-free, suitable for reflow and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode connects to first protected line (e.g., CANH); cathode ties to common return, enabling unidirectional clamping to ground. |
| 2 | K2 (Cathode 2) | Anode connects to second protected line (e.g., CANL); shares cathode node (Pin 3) with K1 for compact dual-line layout. |
| 3 | CC (Common Cathode) | Single low-inductance ground reference point for both diodes - minimizes loop area and improves ESD current path efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Supports ±22 kV IEC 61000-4-2 protection on both signal lines without polarity constraints on PCB routing. |
| Capacitance Matching | ≤0.5% ΔCd/Cd between channels - maintains differential signal symmetry critical for CAN-FD common-mode rejection. |
| Low-Leakage Operation | 1 nA typical IRM at 36 V - prevents DC loading on high-impedance bus terminations and avoids false wake-up in sleep modes. |
| Thermal Derating Curve | PPP drops to 40% at 150 °C - enables accurate power-handling prediction in engine bay environments with elevated ambient temperatures. |
Applications
| Automotive CAN-FD Bus Protection | 24 V Truck Network Interface |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface of a vehicle gateway module handling multiple CAN-FD domains. IC Role / Device Role / Timing Role: Dual-line transient voltage suppressor placed within 3 mm of connector pins to clamp ESD before reaching CAN transceiver inputs. Use Value: Prevents latch-up or permanent damage to NXP TJA1044GK transceivers during service technician hot-plug events. | Use Scenario: Front-end protection for telematics control unit (TCU) in Class 8 heavy-duty trucks with 24 V nominal board net. IC Role / Device Role / Timing Role: Common-cathode dual TVS providing coordinated clamping on CANH/CANL lines exposed to chassis-ground transients. Use Value: Maintains <10 pF loading to preserve 2 Mbps CAN signal edge rate while surviving 22 kV ESD pulses per ISO 10605. |
| FlexRay Communication Node | SENT Sensor Interface Protection |
Use Scenario: Signal line protection in ADAS domain controller supporting FlexRay communication at 10 Mbps. IC Role / Device Role / Timing Role: Low-capacitance dual TVS placed adjacent to FlexRay transceiver (e.g., TJA1080A) to limit ESD-induced jitter. Use Value: 10 pF capacitance ensures <0.5 UI timing uncertainty on 10 Mbps differential signals, meeting FlexRay physical layer spec. | Use Scenario: Single-wire SENT (SAE J2716) sensor interface in powertrain control module, where ESD risk exists at harness connectors. IC Role / Device Role / Timing Role: One channel used for SENT data line protection; second channel unused or repurposed for auxiliary signal line. Use Value: 36 V VRWM exceeds SENT's 12 V supply rail, preventing leakage during normal operation while clamping ESD above 43 V. |
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 |
|---|---|---|---|
| ESD56081D05-2/TR | Higher 5.5 V VRWM; 12 pF capacitance; 24 kV ESD rating | Targeted at 5 V logic-level buses (e.g., USB, LIN), not 24 V/36 V automotive networks | Select only if protecting low-voltage digital interfaces-not suitable for CAN-FD or FlexRay. |
| TPD2E007DRYR | 7 V VRWM; 3.5 pF capacitance; 8 kV IEC 61000-4-2 rating | Designed for portable electronics; lacks AEC-Q101 qualification and automotive thermal range | Not qualified for automotive use; insufficient ESD robustness and thermal endurance for vehicle deployment. |
Compared with ESD56081D05-2/TR and TPD2E007DRYR, PESD2CANFD36LU-QX uniquely combines 36 V standoff, 22 kV ESD immunity, AEC-Q101 qualification, and matched low capacitance-making it the only validated solution for CAN-FD and FlexRay in harsh automotive environments.

FAQ
What is the maximum peak pulse current this device can handle?
The PESD2CANFD36LU-QX supports a rated peak pulse current (IPPM) of 3.2 A under 8/20 µs waveform per IEC 61000-4-5. This value is measured from either Pin 1 or Pin 2 to Pin 3 and reflects single-pulse capability under standardized surge conditions.
Can this device protect both CANH and CANL simultaneously?
Yes - its dual-diode common-cathode configuration allows simultaneous protection of CANH (connected to Pin 1 anode) and CANL (connected to Pin 2 anode), with both cathodes tied to Pin 3 (CC) for coordinated clamping to ground without cross-talk or imbalance.
Is the 10 pF capacitance specified at DC or AC bias?
The 10 pF maximum capacitance is measured at 1 MHz and 2.5 V reverse bias (VR = −2.5 V), per Table 6 in the datasheet. It represents small-signal AC capacitance relevant to high-speed bus signal integrity, not DC junction capacitance.
Does this part require external series impedance for optimal ESD performance?
No external series resistor is required - the device is designed for direct placement at the connector. However, layout best practices mandate minimizing trace length (<3 mm) between connector and Pins 1/2, and using a solid ground plane connected directly to Pin 3 to ensure low-inductance transient return path.
