Product details
Overview
PESD2CANFD24U-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 ±15 kV and ISO 10605 ±15 kV (150 pF/330 Ω) transients, with 24 V reverse standoff voltage, 33 V clamping at 1 A, and 3.5 pF capacitance per channel.
For engineers reviewing the PESD2CANFD24U-QC datasheet, PESD2CANFD24U-QC pinout, PESD2CANFD24U-QC application, or PESD2CANFD24U-QC equivalent, this device is selected for high-speed, low-capacitance ESD protection in safety-critical automotive serial bus interfaces where signal integrity, AEC-Q101 qualification, and side-wettable flank solderability are mandatory.
Technical Context
This bidirectional ESD protection array integrates two independent TVS diodes sharing a common cathode (pin 3), enabling symmetrical transient suppression on two differential bus lines (e.g., CANH/CANL). Its low dynamic resistance (1 Ω typical) and fast response (<1 ns) ensure effective clamping during sub-nanosecond ESD events.
The device operates within –55 °C to +150 °C ambient range and supports peak pulse current up to 1.9 A (8/20 µs waveform), with junction temperature limited to 150 °C. Capacitance matching between channels (±0.5%) minimizes skew in differential signaling paths.
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 at 1 A - Limits transient voltage to safe levels below CAN transceiver absolute maximum ratings. |
| Diode Capacitance | 3.5 pF at 1 MHz / –2.5 V - Preserves signal integrity on >5 Mbps CAN-FD buses with minimal rise-time degradation. |
| ESD Rating | ±15 kV IEC 61000-4-2 contact - Meets automotive OEM ESD immunity requirements for exterior connectors. |
| AEC-Q101 Qualified | Qualified for automotive use - Validated for reliability under temperature cycling, HTRB, and ESD stress per AEC standard. |
| Package | DFN1412D-3 (SOT8009) - 1.4 mm × 1.2 mm × 0.48 mm body with side-wettable flanks for automated optical solder-joint inspection. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-thin surface-mount package with side-wettable flanks for AOI-compatible reflow assembly. Dimensions: 1.4 mm × 1.2 mm × 0.48 mm, 0.8 mm pitch, and 0.02 mm max flank protrusion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms anode-to-ground path for positive transients. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); enables independent clamping per bus line. |
| 3 | CC (Common Cathode) | Shared ground reference terminal; ties both diodes to system ground with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel symmetric protection | Two matched TVS diodes share one cathode terminal, enabling compact layout for differential bus pairs without cross-talk penalty. |
| Low capacitance matching | ±0.5% capacitance mismatch between pins 1–3 and 2–3 ensures <1 ps skew in high-speed CAN-FD timing margins. |
| Side-wettable flanks | Facilitates automated optical inspection of solder joints on bottom-terminated terminals-critical for automotive PCB process control. |
| High surge robustness | 1.9 A rated peak pulse current (8/20 µs) supports protection against coupled surges per ISO 7637-3 Pulse 5a. |
Applications
| Automotive CAN-FD Bus Protection | Automotive CAN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed (up to 5 Mbps) CAN-FD communication between ADAS ECUs and domain controllers in electric vehicles. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point to clamp ESD before reaching CAN transceiver input stage. Use Value: Prevents latch-up or permanent damage to transceivers during factory handling or roadside ESD events while maintaining signal fidelity via 3.5 pF capacitance. | Use Scenario: Securing legacy 1 Mbps CAN networks in powertrain control modules exposed to engine bay EMI and human-body-model discharges. IC Role / Device Role / Timing Role: Low-leakage (1 nA @ 24 V) ESD clamp that remains transparent during nominal bus operation (±5 V differential swing). Use Value: Eliminates need for external RC filters by combining high ESD immunity (±15 kV) with negligible loading on 120 Ω terminated bus lines. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Safeguarding FlexRay physical layer in chassis control units operating at 10 Mbps with strict jitter and noise budgets. IC Role / Device Role / Timing Role: Common-cathode dual-diode structure provides matched clamping on both data lines (A/B), preserving differential symmetry. Use Value: ±0.5% capacitance matching prevents duty-cycle distortion and maintains <1% bit error rate under repeated ESD stress. | Use Scenario: Protecting single-wire SENT (Single Edge Nibble Transmission) sensor outputs in engine management systems subject to under-hood ESD. IC Role / Device Role / Timing Role: Low-standby-current protector (1 nA leakage) that avoids interfering with SENT's precise pulse-width encoding. Use Value: Enables direct placement at sensor harness connector without degrading 12-bit resolution or introducing timing uncertainty in pulse edges. |
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-W02 | 22 V VRWM, 30 V VCL at 1 A, 3.0 pF capacitance, same DFN1412-3 package | Lower clamping voltage suits 12 V CAN systems but may not sustain 24 V battery rail transients | Select when lower clamping priority outweighs higher standoff margin. |
| ON Semiconductor NUF2221MUTAG | 24 V VRWM, 36 V VCL at 1 A, 5.5 pF capacitance, SOT-143 package (larger, no SWF) | Higher capacitance limits use to ≤1 Mbps CAN; lacks side-wettable flanks for AOI | Choose only if footprint compatibility with legacy SOT-143 designs is required. |
Compared with ESD224-B1-W02 and NUF2221MUTAG, PESD2CANFD24U-QC delivers optimal balance of 24 V standoff, 33 V clamping, 3.5 pF capacitance, and AEC-Q101-qualified DFN1412D-3 packaging-making it the preferred choice for new CAN-FD and FlexRay designs requiring production-ready manufacturability and signal integrity.

FAQ
What is the maximum junction temperature rating for PESD2CANFD24U-QC?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 stress testing. This allows operation in under-hood environments up to 125 °C ambient with appropriate PCB copper pour and thermal vias to maintain Tj ≤ 150 °C under peak 1.9 A surge conditions.
Does PESD2CANFD24U-QC support bidirectional transient suppression on both protected lines?
Yes-it uses two independent, bidirectional TVS diodes sharing a common cathode (pin 3). Each diode (pins 1–3 and 2–3) clamps positive and negative transients equally, enabling full protection for differential bus signals like CANH/CANL without polarity constraints.
How does the side-wettable flank design impact manufacturing yield?
The side-wettable flanks (SWF) on the DFN1412D-3 package enable automated optical inspection (AOI) of solder fillets on all three terminals, improving first-pass yield in automotive PCB assembly by detecting insufficient solder, bridging, or misalignment before functional test.
Can PESD2CANFD24U-QC be used for USB 2.0 or other non-automotive high-speed interfaces?
No-it is optimized for 24 V automotive bus systems and qualified only to AEC-Q101. Its 3.5 pF capacitance and 24 V VRWM are mismatched for 3.3 V USB 2.0 (which requires ≤1.5 pF and ≤5 V VRWM); using it risks signal attenuation and failure to meet USB eye diagram specs.
