Product details
Overview
PESD2CANFD24UQC-QZ from Nexperia is a dual-channel automotive-grade ESD protection diode in a DFN1412D-3 (SOT8009) package, designed to safeguard CAN-FD and CAN bus lines against ±15 kV IEC 61000-4-2 and ISO 10605 transients. It features 24 V reverse standoff voltage, 33 V clamping at 1 A, 3.5 pF capacitance, and AEC-Q101 qualification for under-hood vehicle networking.
For engineers reviewing the PESD2CANFD24UQC-QZ datasheet, PESD2CANFD24UQC-QZ pinout, PESD2CANFD24UQC-QZ application, or PESD2CANFD24UQC-QZ equivalent, key selection criteria include bidirectional clamping performance, low capacitance for high-speed bus integrity, side-wettable flank compatibility with automated optical inspection (AOI), and validated operation across −55 °C to +150 °C ambient range.
Technical Context
This device implements a common-cathode dual-diode architecture with independent cathodes (K1, K2) tied to a shared cathode terminal (CC), enabling symmetrical transient suppression on two differential bus lines without cross-talk. Its low dynamic resistance (1 Ω) and fast response (<1 ns) ensure effective clamping of ESD pulses per IEC 61000-4-2 and surge events per IEC 61000-4-5 (8/20 µs).
Designed specifically for automotive serial buses, it maintains signal fidelity on CAN-FD (up to 5 Mbps) and legacy CAN (1 Mbps) by limiting capacitance mismatch to ≤0.5% between channels and holding leakage current to ≤50 nA at 24 V, minimizing standby power impact and ensuring robust common-mode noise rejection.

| 2 | K2 (Cathode 2) | Connects to protected line 2 (e.g., CANL); provides independent clamping path for negative transients on channel 2. |
| 3 | CC (Common Cathode) | Shared cathode node tied to system ground or chassis; enables bidirectional clamping via dual anti-parallel paths (K1–CC and K2–CC). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Simultaneous protection of two differential bus lines using shared cathode architecture-no external grounding complexity or asymmetry. |
| Side-Wettable Flanks (SWF) | Enables reliable AOI and X-ray inspection of solder joints in high-volume automotive PCB assembly without requiring intrusive testing. |
| Capacitance Matching | ≤0.5% difference between Cd1 (pin 1–3) and Cd2 (pin 2–3), preserving differential signal integrity and common-mode rejection on high-speed buses. |
| Low-Leakage Operation | ≤50 nA reverse leakage at 24 V ensures negligible current draw in always-on vehicle networks, supporting low-power sleep modes. |
| Thermal Robustness | 150 °C max junction temperature rating supports sustained operation in proximity to power electronics and engine compartments. |
Applications
| CAN-FD Bus Protection | CAN Legacy Bus Protection |
|---|---|
Use Scenario: Protecting high-speed Controller Area Network Flexible Data-Rate (CAN-FD) interfaces in ADAS domain controllers and gateway ECUs exposed to connector-level ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at the connector entry point, shunting ESD energy to chassis ground before reaching the CAN-FD transceiver. Use Value: Maintains signal integrity up to 5 Mbps with 3.5 pF capacitance and prevents latch-up or damage to transceivers rated for ≤36 V absolute maximum. | Use Scenario: Safeguarding legacy CAN 2.0B nodes (e.g., body control modules, instrument clusters) against electrostatic discharge during service or environmental exposure. IC Role / Device Role / Timing Role: Dual-line ESD clamp mounted adjacent to the CAN transceiver's TX/RX pins, providing symmetric clamping on both CANH and CANL lines. Use Value: Delivers ±15 kV contact ESD protection while adding <1 ns propagation delay-no impact on 1 Mbps timing budgets or arbitration latency. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Securing FlexRay communication links in powertrain and chassis control units where deterministic timing and fault tolerance are critical. IC Role / Device Role / Timing Role: Low-capacitance dual-channel protector placed at FlexRay physical layer interface, suppressing transients without degrading 10 Mbps differential signaling. Use Value: 3.5 pF capacitance and ≤0.5% matching preserve signal rise/fall times and minimize bit error rate in time-triggered protocols. | Use Scenario: Shielding Single Edge Nibble Transmission (SENT) sensor inputs (e.g., pressure, temperature) in engine bay applications subject to repeated ESD events. IC Role / Device Role / Timing Role: Point-of-entry ESD suppressor on SENT signal line and VREF line, leveraging common-cathode configuration for compact dual-rail protection. Use Value: 24 V VRWM accommodates SENT's 5–12 V supply range and 33 V clamping prevents overvoltage damage to microcontroller input comparators. |
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 |
|---|---|---|---|
| STUSB4710QTR | Integrated USB-C port protection IC with integrated switch; higher capacitance (12 pF), no AEC-Q101 qualification. | Targeted at infotainment USB interfaces-not suitable for CAN-FD or under-hood deployment. | Select only for non-automotive USB-C accessory ports requiring integrated overvoltage and overcurrent protection. |
| ON Semiconductor NUF2221MUTAG | 2-channel ESD array with 22 V VRWM, 30 V clamping, 12 pF capacitance, AEC-Q101 qualified. | Limited to 1 Mbps CAN due to higher capacitance; lower standoff voltage reduces margin on 24 V systems. | Acceptable for cost-sensitive 12 V CAN nodes where 22 V VRWM suffices and 12 pF capacitance is tolerable. |
Compared with STUSB4710QTR and NUF2221MUTAG, PESD2CANFD24UQC-QZ uniquely balances 24 V standoff, 3.5 pF capacitance, and AEC-Q101 compliance-making it the only option validated for CAN-FD in harsh thermal environments without compromising data rate or reliability.

FAQ
What is the maximum recommended PCB trace length between PESD2CANFD24UQC-QZ and the protected CAN connector?
Per Nexperia application guidance, the trace length from the device to the connector should be ≤3 mm to minimize inductance and preserve clamping effectiveness. Longer traces increase voltage overshoot during ESD events; layout must also avoid vias or splits in the ground return path to maintain low-impedance transient dissipation.
Does PESD2CANFD24UQC-QZ require external series resistors or TVS diodes for full IEC 61000-4-5 surge protection?
No-PESD2CANFD24UQC-QZ is rated for 1.9 A peak pulse current (8/20 µs) per IEC 61000-4-5 and does not require supplemental series impedance. However, for Level 4 (4 kV) surge compliance, system-level design must include proper grounding, common-mode chokes, and board-level layout per Figure 11 in the datasheet.
Can PESD2CANFD24UQC-QZ be used to protect RS-485 or LIN bus lines?
It is not recommended for RS-485 due to its 24 V VRWM exceeding typical RS-485 receiver input ranges (±7 V); for LIN, the 24 V standoff is excessive and capacitance may affect 20.5 kbps timing margins. Dedicated LIN/RS-485 protectors (e.g., PESD1LIN24U, PRTR5V0U2X) are better matched.
How is the common cathode (pin 3) connected in a typical CAN-FD layout?
In standard implementation, pin 3 (CC) connects directly to a low-inductance chassis or functional ground plane-never to signal ground alone. The ground connection must be short (<5 mm), wide, and via-stitched to inner ground layers to ensure transient energy is shunted away from the CAN transceiver's ground reference.
