Product details
Overview
PESD2CANFD36VU-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 ±20 kV IEC 61000-4-2 ESD events, with 36 V reverse standoff voltage, 45 V clamping at 1 A, and 6 pF capacitance per channel - deployed at vehicle-level ECUs and gateway modules.
For engineers reviewing the PESD2CANFD36VU-QX datasheet, PESD2CANFD36VU-QX pinout, PESD2CANFD36VU-QX application, or PESD2CANFD36VU-QX equivalent, key selection criteria include bidirectional clamping performance under 100 ns TLP pulses, AEC-Q101 qualification status, common-cathode dual-diode topology for differential bus protection, and low capacitance matching (<0.5%) across channels.
Technical Context
This device implements a common-cathode dual-diode architecture where pins 1 and 2 serve as independent cathodes for two ESD protection paths, both referenced to shared pin 3 (CC). It operates bidirectionally without external bias, leveraging silicon avalanche clamping to limit transients on high-speed automotive buses.
Clamping is characterized using Transmission Line Pulse (TLP) testing at 100 ns pulse width, delivering 50 V typical clamping at 16 A, while maintaining dynamic resistance ≤1 Ω. Capacitance is measured at 1 MHz and ±2.5 V reverse bias, ensuring signal integrity on CAN-FD (up to 5 Mbps) and SENT interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Maximum continuous operating voltage before leakage exceeds 1 µA; sets upper limit for bus DC bias compatibility. |
| Clamping Voltage | 45 V at 1 A (8/20 µs) - Peak voltage seen by protected IC during surge; ensures downstream CAN transceiver remains within absolute max ratings. |
| ESD Withstand | ±20 kV IEC 61000-4-2 contact discharge - Validated immunity level for direct human-body ESD events in vehicle assembly and service environments. |
| Diode Capacitance | 6 pF per channel at 1 MHz / -2.5 V - Enables <1% signal distortion on 5 Mbps CAN-FD differential pairs; matched to ±0.5% between channels. |
| Peak Pulse Current | 2 A (8/20 µs waveform) - Sustains transient energy from ISO 7637-3 coupled surges without degradation; rated per IEC 61000-4-5. |
| Junction Temperature | 150 °C max - Supports operation in under-hood ECU enclosures with ambient up to 125 °C and power dissipation derating. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body height. RoHS-compliant, halogen-free, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | ESD current sink path for first protected line (e.g., CANH); connects to anode of internal diode 1. |
| 2 | K2 (Cathode 2) | ESD current sink path for second protected line (e.g., CANL); connects to anode of internal diode 2. |
| 3 | CC (Common Cathode) | Shared cathode node tied to system ground; enables compact dual-line protection with single ground return. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive use per stress test standard including HTGB, HTRB, and ESD; supports PPAP documentation. |
| Low Capacitance Matching | ΔCd/Cd ≤ 0.5% - Minimizes skew between differential signals on CAN-FD or SENT buses, preserving timing margins. |
| Bidirectional Clamping | No external bias required - protects against both positive and negative transients on same bus line without polarity constraints. |
| Common-Cathode Topology | Reduces PCB footprint vs. discrete dual-diode solutions; eliminates need for separate ground traces per channel. |
Applications
| Automotive CAN-FD Bus Protection | Truck 24 V Board Net ESD Guarding |
|---|---|
Use Scenario: Installed at OBD-II connector interface of ADAS domain controller to suppress ESD during diagnostic cable insertion. IC Role / Device Role: Transient voltage suppressor placed directly between CANH/CANL and ground, upstream of CAN transceiver. Use Value: Limits clamped voltage to ≤50 V during 16 A TLP event, preventing latch-up or damage to TJA1044G transceiver inputs. |
Use Scenario: Mounted on heavy-duty truck telematics module PCB near J1939 DB9 connector. IC Role / Device Role: Dual-line ESD clamp for 24 V nominal J1939 bus, handling combined ESD + load-dump coupling. Use Value: Maintains 6 pF capacitance to avoid signal rise-time degradation on 250 kbps J1939, while surviving ±20 kV contact discharge. |
| FlexRay Communication Line Guard | SENT Sensor Interface Protection |
Use Scenario: Integrated into chassis control unit supporting FlexRay communication at 10 Mbps. IC Role / Device Role: High-speed ESD shunt for differential FlexRay A/B lines, placed adjacent to bus termination resistors. Use Value: 6 pF/channel capacitance ensures <0.5 ns added propagation delay, preserving deterministic timing for safety-critical braking commands. |
Use Scenario: Deployed on engine control unit PCB protecting SENT output driving pressure sensor feedback. IC Role / Device Role: Single-point ESD clamp on unidirectional SENT signal line referenced to chassis ground. Use Value: 36 V VRWM accommodates SENT's 5–12 V supply range; 45 V clamping prevents overvoltage on MCU GPIO input. |
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 |
|---|---|---|---|
| NUP4202MR6T1G | Higher 12 pF capacitance; 33 V VRWM; SO-8 package (larger footprint) | Targeted at lower-speed LIN/CAN 2.0; not optimized for CAN-FD 5 Mbps signal integrity | Select when board space allows larger package and 12 pF is acceptable for legacy bus speeds. |
| TPD2E007DRYR | Lower 3.5 pF capacitance; 5 V VRWM; 3-pin X2SON package; non-AEC-Q101 | Designed for consumer USB/IO protection; lacks automotive qualification and 36 V standoff | Use only in non-automotive, low-voltage, high-speed digital interfaces - not suitable for CAN-FD or 24 V systems. |
Compared with NUP4202MR6T1G and TPD2E007DRYR, PESD2CANFD36VU-QX uniquely balances 6 pF capacitance, 36 V standoff, AEC-Q101 compliance, and SOT323 size - making it the only option validated for CAN-FD and FlexRay in space-constrained automotive modules.

FAQ
Is PESD2CANFD36VU-QX compatible with 5 Mbps CAN-FD data rates?
Yes. Its 6 pF typical capacitance per channel, matched to ±0.5%, introduces negligible signal distortion on differential CAN-FD pairs. Measured TLP clamping response time is <1 ns, ensuring no timing skew or bit error rate degradation at full 5 Mbps operation.
What is the recommended PCB layout for optimal ESD performance?
Place the device within 3 mm of the connector entry point; route protected lines directly to pins 1 and 2 with minimum trace length; connect pin 3 to a solid ground plane via ≥2 vias; avoid stubs or splits in the ground return path to maintain low-inductance clamping.
Does PESD2CANFD36VU-QX require external bias or direction control?
No. It operates bidirectionally without external bias due to its symmetric common-cathode dual-diode structure. Each channel conducts during both positive and negative transients relative to ground, eliminating polarity concerns during layout or integration.
How does its AEC-Q101 qualification differ from standard industrial ESD protectors?
AEC-Q101 validation includes 1000-hour high-temperature reverse bias (HTRB), temperature cycling (-55 °C to +150 °C), and mechanical shock testing - confirming reliability under automotive thermal, vibration, and humidity stresses that generic ESD diodes do not undergo.
