Product details
Overview
PESD2CANFD24V-QC from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1412D-3 (SOT8009) package, designed to safeguard CAN-FD and CAN bus lines against IEC 61000-4-2 ±23 kV contact discharge and ISO 10605 ±23 kV (150 pF/330 Ω) transients, with 24 V reverse standoff voltage, 33 V clamping at 1 A, and 6 pF typical capacitance per channel.
For engineers reviewing the PESD2CANFD24V-QC datasheet, PESD2CANFD24V-QC pinout, PESD2CANFD24V-QC application, or PESD2CANFD24V-QC equivalent, this device supports high-speed automotive serial bus protection where low capacitance, AEC-Q101 qualification, and precise bidirectional clamping are required for signal integrity and system-level ESD robustness.
Technical Context
This device implements two independent, common-cathode-connected TVS diodes in a single ultra-compact leadless package-pin 1 (K1) and pin 2 (K2) serve as anode terminals for separate protected lines, while pin 3 (CC) provides shared cathode return. Its bidirectional clamping behavior enables symmetric transient suppression on differential bus pairs without polarity constraints.
Designed specifically for CAN-FD's 5 Mbps+ signaling, it maintains ≤6 pF capacitance at 2.5 V reverse bias to minimize signal distortion, and achieves dynamic resistance of 0.7 Ω (TLP, 10 A), ensuring rapid voltage clamping within 30 ns (±8 kV ESD pulse) while sustaining 2.6 A peak pulse current per line under 8/20 µs surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN-FD bus operation (±12 V common-mode range) |
| Clamping Voltage | 33 V (typ.) at 1 A - Limits transient voltage to safe levels below CAN transceiver absolute maximum ratings |
| ESD Rating | ±23 kV IEC 61000-4-2 contact - Meets automotive OEM ESD immunity requirements for connector-facing protection |
| Diode Capacitance | 6 pF (typ.) at 1 MHz / 2.5 V - Preserves signal edge integrity up to 5 Mbps CAN-FD data rates |
| Peak Pulse Current | 2.6 A (8/20 µs) - Handles repetitive surges per ISO 7637-3 without degradation |
| Junction Temperature | 150 °C max - Supports under-hood deployment in extended temperature environments |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validated for automotive production use |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, side-wettable flank package measuring 1.4 mm × 1.2 mm × 0.48 mm with 0.8 mm pitch. Its ultra-thin profile and SWF design enable automated optical inspection (AOI) and reliable reflow soldering in space-constrained automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Anode of Diode 1 | Connects to first protected bus line (e.g., CANH); conducts during negative transients |
| 2 (K2) | Anode of Diode 2 | Connects to second protected bus line (e.g., CANL); independent clamping path |
| 3 (CC) | Common Cathode | Shared low-impedance return path to ground plane; enables compact dual-line layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode architecture | Enables simultaneous protection of differential CAN-FD lines with single-component footprint and minimized PCB routing |
| Side-wettable flanks (SWF) | Supports automated optical inspection of solder joints-critical for zero-defect automotive manufacturing |
| Low capacitance matching (≤0.5% ΔCd/Cd) | Maintains differential signal balance and minimizes skew between CANH/CANL paths |
| Bidirectional clamping | Protects against both positive and negative ESD events without external bias or polarity constraints |
| Dynamic resistance of 0.7 Ω | Reduces clamping overshoot and ensures fast response (<30 ns) to sub-nanosecond ESD rise times |
Applications
| CAN-FD Bus Protection | CAN Legacy Bus Protection |
|---|---|
|
Use Scenario: High-speed powertrain control module interfacing with CAN-FD backbone at 5 Mbps. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector entry point before CAN transceiver input pins. Use Value: Prevents latch-up or damage to CAN FD transceivers (e.g., TJA1057x) during assembly handling or field ESD events while preserving signal rise/fall time. |
Use Scenario: Body control unit (BCU) using legacy CAN 1 Mbps for door module communication. IC Role / Device Role / Timing Role: Dual-line protector mounted adjacent to DB9 or mini-USB automotive connector. Use Value: Maintains <1 ns inter-channel capacitance mismatch to avoid CAN differential skew, ensuring bit error rate compliance over 15 m cable runs. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
|
Use Scenario: Chassis domain controller with FlexRay 10 Mbps fault-tolerant bus for active suspension control. IC Role / Device Role / Timing Role: Point-of-entry protector on FlexRay A/B differential pair prior to physical layer IC. Use Value: 6 pF capacitance prevents signal attenuation above 10 MHz bandwidth, supporting FlexRay's deterministic timing requirements. |
Use Scenario: Engine control unit receiving analog sensor data via SENT protocol from pressure or knock sensors. IC Role / Device Role / Timing Role: Single-line protector on SENT signal line (VDD or data line) at ECU header interface. Use Value: 24 V VRWM avoids leakage during 12 V supply transients; ±23 kV ESD rating exceeds ISO 11452-2 component-level test limits. |
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 ESD224-B1-W | 22 V VRWM, 35 V VCL @ 1 A, 10 pF Cd - higher capacitance, lower standoff | Targeted at 12 V CAN systems only; not rated for CAN-FD 5 Mbps due to bandwidth limitation | Select when protecting legacy 12 V CAN nodes where margin to bus voltage is tighter and speed is ≤1 Mbps |
| ON Semiconductor NUF2221MUTAG | 24 V VRWM, 36 V VCL @ 1 A, 12 pF Cd - larger 2.1 mm × 1.6 mm UDFN package, no SWF | Lacks side-wettable flanks; unsuitable for AOI-based automotive SMT lines requiring SWF verification | Prefer for non-automotive industrial CAN applications where AOI is not mandated and board space allows larger footprint |
Compared with ESD224-B1-W and NUF2221MUTAG, PESD2CANFD24V-QC uniquely combines CAN-FD–optimized 6 pF capacitance, AEC-Q101 qualification, side-wettable flanks for automotive process control, and 24 V standoff-making it the only option qualified for next-generation high-speed automotive serial bus protection with full production traceability.

FAQ
What is the maximum operating temperature for PESD2CANFD24V-QC?
The device is rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to +150 °C, enabling placement near heat-generating components in engine control units or transmission control modules without derating.
Can PESD2CANFD24V-QC protect both CANH and CANL simultaneously?
Yes-pins 1 (K1) and 2 (K2) connect independently to CANH and CANL, while pin 3 (CC) serves as their shared cathode node. This configuration provides matched, bidirectional clamping for differential bus protection without additional components.
Is the 6 pF capacitance measured per channel or total?
The 6 pF value is specified per diode-i.e., capacitance from pin 1 to pin 3 and from pin 2 to pin 3-each measured at 1 MHz and 2.5 V reverse bias, with ≤0.5% mismatch between channels to preserve differential signal integrity.
Does PESD2CANFD24V-QC require external bias or series impedance?
No-this is a passive, bidirectional TVS diode array requiring no external bias, pull-up/down resistors, or series current-limiting elements. It operates solely on transient voltage threshold behavior and is installed directly between protected line and ground reference.
