Product details
Overview
PESD2CANFD36VU-Q from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 package, designed for bidirectional transient suppression on CAN-FD and FlexRay bus lines. It features 36 V reverse standoff voltage, 45 V clamping at 1 A, 6 pF capacitance per channel, AEC-Q101 qualification, and 20 kV IEC 61000-4-2 ESD immunity - deployed at connector interfaces in 24 V truck ECUs.
For engineers reviewing the PESD2CANFD36VU-Q datasheet, PESD2CANFD36VU-Q pinout, PESD2CANFD36VU-Q application, or PESD2CANFD36VU-Q equivalent, key selection criteria include low clamping voltage under 16 A TLP stress, matched diode capacitance (<0.5% ΔCd), common-cathode dual-diode topology for differential bus protection, and SC-70 footprint compatibility with high-density automotive PCB layouts.
Technical Context
This device implements a dual common-cathode TVS diode architecture optimized for differential automotive data buses. Each channel provides symmetrical bidirectional clamping between line and common cathode (pin 3), with breakdown voltage of 37–47 V and dynamic resistance of 1 Ω under 100 ns TLP pulses.
It operates within −55 °C to 150 °C ambient range, supports 2 A peak pulse current (8/20 µs), and maintains ≤50 nA reverse leakage at 36 V - enabling robust protection without signal integrity degradation on CAN-FD physical layers operating up to 5 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - maximum continuous working voltage before conduction; ensures no interference with 24 V board net or CAN-FD common-mode range. |
| Clamping Voltage | 45 V at 1 A (8/20 µs); 50 V at 16 A (TLP) - limits transient overvoltage seen by downstream CAN transceiver I/O pins. |
| Diode Capacitance | 6 pF at 2.5 V reverse bias - preserves signal edge integrity and minimizes jitter on high-speed CAN-FD buses (≤5 Mbps). |
| ESD Withstand | 20 kV contact discharge (IEC 61000-4-2) - meets automotive OEM requirements for connector-level ESD robustness. |
| AEC-Q101 Qualification | Qualified per Stress Test Qualification for Discrete Semiconductors - validates reliability for under-hood and chassis-mounted modules. |
| Peak Pulse Current | 2 A (8/20 µs waveform per IEC 61000-4-5) - handles surge events from load dump or inductive switching in 24 V systems. |
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 on high-density automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected bus line (e.g., CANH); forms clamping path to common cathode during positive transients. |
| 2 | K2 (cathode of diode 2) | Connects to second protected bus line (e.g., CANL); enables independent but referenced clamping for differential pair. |
| 3 | CC (common cathode) | Shared return node tied to system ground or chassis; establishes reference for bidirectional clamping on both lines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode topology | Enables compact, symmetric protection of differential bus pairs (CANH/CANL) without external grounding complexity. |
| 6 pF matched capacitance (ΔCd ≤ 0.5%) | Maintains impedance balance across differential lines, minimizing skew and common-mode noise injection. |
| 45 V clamping at 1 A (8/20 µs) | Keeps protected transceiver I/O within safe SOA during real-world ESD events while avoiding latch-up. |
| AEC-Q101 qualified junction temperature range | Supports operation from −55 °C to +150 °C - suitable for engine control units and transmission control modules. |
Applications
| Automotive CAN-FD Interface Protection | 24 V Truck Network ESD Suppression |
|---|---|
Use Scenario: Protecting CAN-FD physical layer in ADAS domain controllers where data rates reach 5 Mbps and ESD exposure occurs at vehicle harness connectors. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, clamping fast-rising ESD pulses before they reach the CAN transceiver. Use Value: Prevents transceiver damage and communication dropouts during 20 kV contact discharge events while adding <6 pF loading per line. |
Use Scenario: Safeguarding FlexRay or SENT bus lines in heavy-duty truck ECUs exposed to harsh electromagnetic environments and frequent handling-related ESD. IC Role / Device Role / Timing Role: Dual-line ESD clamp referenced to chassis ground, absorbing ±20 kV transients without degrading signal rise/fall times. Use Value: Enables compliance with ISO 16750-2 and OEM-specific ESD test plans without requiring additional filtering or layout compromises. |
| FlexRay Bus Line Protection | SENT Sensor Interface Protection |
Use Scenario: Securing FlexRay communication links in powertrain gateways where deterministic timing and fault tolerance are critical. IC Role / Device Role / Timing Role: Low-capacitance dual TVS diode providing symmetrical clamping on FlexRay A/B lines relative to common ground reference. Use Value: Maintains <1 ns inter-line skew and prevents bit errors caused by transient-induced common-mode noise on 10 Mbps FlexRay buses. |
Use Scenario: Shielding SENT (Single Edge Nibble Transmission) sensor interfaces in engine management systems from ESD coupling via wiring harnesses. IC Role / Device Role / Timing Role: Fast-response ESD clamp on SENT signal and return lines, referenced to shared cathode to preserve signal polarity integrity. Use Value: Ensures uninterrupted sensor data streaming during assembly-line ESD events, avoiding false fault codes or limp-mode activation. |
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 |
|---|---|---|---|
| ESD56031D05-2/TR | 5 V VRWM, 12 pF capacitance, 30 kV ESD rating | Targeted for 5 V logic-level buses (e.g., USB, I²C), not 24 V CAN-FD | Select only for low-voltage digital interfaces; unsuitable for 36 V standoff requirement. |
| TPD2E001DRYR | 5 V VRWM, 10 pF, 15 kV ESD, SOT-5X3 package | Designed for consumer electronics; lacks AEC-Q101 qualification and automotive thermal specs | Not recommended for automotive deployment due to unqualified reliability and insufficient thermal margin. |
Compared with PESD2CANFD36VU-Q, ES56031D05-2/TR offers higher ESD rating but fails to meet 36 V standoff and automotive temperature range, while TPD2E001DRYR lacks AEC-Q101 validation and introduces excessive capacitance for CAN-FD signal integrity.

FAQ
What is the maximum operating temperature for PESD2CANFD36VU-Q?
The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to 150 °C. Its AEC-Q101 qualification confirms thermal stability under sustained high-temperature conditions typical in engine bay and transmission control modules.
Can PESD2CANFD36VU-Q protect both CANH and CANL simultaneously?
Yes - its dual common-cathode structure allows independent connection of CANH to pin 1 and CANL to pin 2, with pin 3 tied to ground. This configuration provides symmetrical bidirectional clamping for both lines without requiring separate devices or complex routing.
Is the 6 pF capacitance measured per channel or total?
The 6 pF value is specified per diode channel (pin 1–3 and pin 2–3), with matching tolerance of ≤0.5% difference between channels. This ensures balanced capacitive loading on differential bus pairs, preserving signal integrity and common-mode rejection.
Does PESD2CANFD36VU-Q require external biasing or control signals?
No - it is a passive, unidirectional clamping device that operates without power, bias, or enable signals. Conduction occurs automatically when transient voltage exceeds the 36 V standoff threshold, making it compatible with all CAN-FD transceivers regardless of vendor or voltage level.
