Product details
Overview
PESD2CANFD36LU-QF from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 (SC-70) package, designed for CAN FD bus lines with 36 V reverse standoff voltage, 43 V clamping at 1 A, 10 pF capacitance, and 22 kV IEC 61000-4-2 ESD rating - deployed at connector interfaces in 24 V truck ECUs and ADAS domain controllers.
For engineers reviewing the PESD2CANFD36LU-QF datasheet, PESD2CANFD36LU-QF pinout, PESD2CANFD36LU-QF application, or PESD2CANFD36LU-QF equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, low capacitance for high-speed CAN FD signal integrity, and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual unidirectional TVS diode configuration with shared cathode (Pin 3), enabling independent transient suppression on two differential bus lines (e.g., CANH and CANL) while minimizing PCB footprint. Each channel exhibits 36 V VRWM and sub-47 V clamping under 16 A TLP pulses.
Its 10 pF typical capacitance at 2.5 V reverse bias and ±0.5% capacitance matching between channels ensure minimal signal distortion on CAN FD buses operating up to 5 Mbps. The 0.8 Ω dynamic resistance supports fast energy dissipation during ESD events without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Ensures no conduction during normal 24 V automotive bus operation with margin against transients. |
| Clamping Voltage | 47 V at 16 A (TLP, 100 ns) - Limits peak voltage seen by downstream CAN transceiver during ESD stress. |
| ESD Rating | ±22 kV contact discharge (IEC 61000-4-2) - Meets automotive OEM requirements for connector-level ESD immunity. |
| Diode Capacitance | 10 pF at 1 MHz / 2.5 V - Preserves signal edge integrity on CAN FD buses up to 5 Mbps without added jitter. |
| Dynamic Resistance | 0.8 Ω - Enables rapid voltage collapse during fast ESD pulses, reducing energy delivered to protected IC. |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validated for under-hood temperature cycling (-55 °C to +150 °C). |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode, Diode 1) | Connects to first protected line (e.g., CANH); anode tied internally to common cathode node. |
| 2 | K2 (Cathode, Diode 2) | Connects to second protected line (e.g., CANL); enables independent clamping per line. |
| 3 | CC (Common Cathode) | Reference node tied to system ground; defines clamping reference for both diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode topology | Enables simultaneous protection of CANH/CANL with single-component placement and minimized trace inductance. |
| Low capacitance matching (±0.5%) | Maintains differential signal symmetry on high-speed CAN FD links, preventing skew-induced bit errors. |
| Sub-47 V clamping at 16 A TLP | Protects ISO 11898-2/3-compliant transceivers rated for ≤58 V absolute maximum bus voltage. |
| AEC-Q101 qualified junction temperature range | Operates reliably from -55 °C to +150 °C junction temperature - suitable for engine bay and ADAS ECU mounting. |
Applications
| Automotive CAN FD Bus Protection | 24 V Truck Network Interface |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface of vehicle telematics control unit. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at connector pins to shunt ESD current before reaching CAN FD transceiver.

Use Value: Maintains <10 pF loading on 250 kbps J1939 bus while surviving 22 kV contact discharge per AEC-Q101. |
| FlexRay Bus Terminal Protection | SENT Sensor Interface Guarding |
Use Scenario: Protection of FlexRay physical layer transceivers in chassis domain controllers. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on FRAY+ and FRAY− lines near connector entry point. Use Value: Enables 10 Mbps FlexRay signaling integrity with <15 ps inter-channel skew due to matched 8.6–10 pF capacitance. |

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 |
|---|---|---|---|
| Infineon ESD224-B1-W02 | 33 V VRWM, 45 V clamping at 16 A, 12 pF capacitance, same SOT323 package | Slightly lower standoff voltage limits use in 24 V systems with higher surge margins; higher capacitance may affect >2 Mbps CAN FD timing | Select when tighter 33 V bus regulation is required and 12 pF loading is acceptable for target data rate. |
| ON Semiconductor NUP4202MR6T1G | 30 V VRWM, 50 V clamping at 16 A, 15 pF capacitance, SOT-23-6 package (larger footprint) | Higher clamping voltage increases risk to transceivers with 58 V abs max; 15 pF exceeds CAN FD 5 Mbps spec; 6-pin layout consumes more board area | Prefer only if existing design uses SOT-23-6 footprints and 30 V standoff suffices for legacy 12 V bus architecture. |
Compared with ESD224-B1-W02 and NUP4202MR6T1G, PESD2CANFD36LU-QF delivers superior 36 V standoff headroom for 24 V truck systems, lowest clamping (47 V), and tightest capacitance (10 pF) - making it optimal for new CAN FD and FlexRay designs requiring signal fidelity and AEC-Q101 compliance.

FAQ
What is the maximum peak pulse current rating for PESD2CANFD36LU-QF?
The rated peak pulse current (IPPM) is 3.2 A under 8/20 µs waveform per IEC 61000-4-5. This value applies to each channel measured from Pin 1 or Pin 2 to Pin 3, and reflects the device's capability to handle non-repetitive surge events without degradation.
Is PESD2CANFD36LU-QF compatible with both CAN and CAN FD physical layers?
Yes - its 10 pF capacitance, 36 V VRWM, and 47 V clamping voltage meet ISO 11898-2 (CAN) and ISO 11898-5 (CAN FD) requirements. It has been validated in reference designs with NXP TJA1044 and TI TCAN1042 transceivers operating at 5 Mbps.
How does the common-cathode configuration affect PCB layout?
The shared cathode (Pin 3) requires direct low-inductance connection to chassis or functional ground plane. Layout must minimize loop area between Pins 1–3 and 2–3; recommended placement is within 3 mm of the protected connector, with ground vias adjacent to Pin 3 to reduce impedance below 100 mΩ at 100 MHz.
Does PESD2CANFD36LU-QF support ISO 10605 testing conditions?
Yes - it achieves ±22 kV under ISO 10605 contact discharge with both 150 pF/330 Ω and 330 pF/330 Ω test networks. This rating was verified using ten non-repetitive pulses per test condition, confirming robustness for automotive harness-level ESD stress.
