Product details
Overview
PESD2CANFD24VQC-QZ 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 ±23 kV IEC 61000-4-2 ESD events, with 24 V reverse standoff voltage, 33 V clamping at 1 A, and 6 pF capacitance per channel.
For engineers reviewing the PESD2CANFD24VQC-QZ datasheet, PESD2CANFD24VQC-QZ pinout, PESD2CANFD24VQC-QZ application, or PESD2CANFD24VQC-QZ equivalent, this device is selected for high-speed, low-capacitance transient suppression in AEC-Q101-compliant vehicle networks where signal integrity and robustness under ISO 10605 (150 pF/330 Ω) stress are critical.
Technical Context
This bidirectional dual-diode array uses common-cathode topology (pins 1 & 2 as cathodes, pin 3 as shared cathode) to provide symmetrical clamping on two independent bus lines. Its 6 pF capacitance per line ensures minimal signal distortion on CAN-FD data rates up to 5 Mbps.
The device operates within −55 °C to +150 °C ambient range and sustains 2.6 A peak pulse current (8/20 µs), with dynamic resistance of 0.7 Ω enabling fast response to sub-ns ESD transients while maintaining low clamping voltage under 1 A stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN-FD bus operation (±12 V differential, ~2.2 V common-mode) |
| Clamping Voltage | 33 V at 1 A - Limits transient voltage to safe levels for CAN transceivers rated ≤ 40 V absolute max |
| ESD Withstand | ±23 kV IEC 61000-4-2 - Meets automotive OEM requirements for connector-level ESD immunity |
| Diode Capacitance | 6 pF at 1 MHz / −2.5 V - Preserves signal edge rate and eye diagram integrity on 5 Mbps CAN-FD buses |
| Peak Pulse Current | 2.6 A (8/20 µs) - Handles surge energy from ISO 7637-2 Load Dump and EFT bursts without degradation |
| Dynamic Resistance | 0.7 Ω - Enables rapid voltage clamping with minimal overshoot during nanosecond-scale ESD events |
| Junction Temperature Max | 150 °C - Supports placement near hot engine-control modules without derating |
Pinout & Package
DFN1412D-3 (SOT8009) is a 1.4 mm × 1.2 mm × 0.48 mm leadless plastic package with side-wettable flanks for automated optical solder-joint inspection. Pitch is 0.8 mm; body thickness includes plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode connects to protected line 1 (e.g., CANH); clamps positive transients to common cathode |
| 2 | K2 (Cathode 2) | Anode connects to protected line 2 (e.g., CANL); enables independent bidirectional protection per line |
| 3 | CC (Common Cathode) | Shared return path to ground or TVS reference; must be routed with low-inductance connection |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified for automotive under stress test conditions including HTGB, HTRB, and temperature cycling - supports 15-year vehicle service life |
| Side-wettable flanks | Enables AOI-compatible solder-joint inspection on bottom-side terminals - critical for zero-defect automotive manufacturing |
| Low capacitance matching | ≤0.5% ΔCd/Cd between channels - maintains common-mode rejection and differential signal balance on CAN pairs |
| ISO 10605 compliance | Rated for ±23 kV (150 pF/330 Ω) - exceeds most OEM requirements for battery-line-connected ECUs |
| Ultra-small footprint | 1.4 mm × 1.2 mm area - fits within tight routing zones near CAN connectors without compromising PCB stack-up |
Applications
| Automotive CAN-FD ECUs | Body Control Modules |
|---|---|

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 protector with integrated switch; 12 V VRWM; higher 15 pF capacitance | Designed for USB 2.0/3.2 interfaces, not optimized for CAN-FD signal integrity | Select only if consolidating USB and CAN protection in gateway modules with separate voltage domains |
| ON Semiconductor NUP4202MR6T1G | Quad-channel; 12 V VRWM; 18 pF typical capacitance; AEC-Q101 qualified | Higher capacitance limits use to ≤1 Mbps CAN; larger SOT-563 package increases board area | Prefer when protecting four low-speed lines (e.g., LIN + CAN + two analog sensors) in cost-sensitive modules |
Compared with STUSB4710QTR and NUP4202MR6T1G, PESD2CANFD24VQC-QZ delivers lower capacitance (6 pF vs. ≥15 pF), higher VRWM (24 V vs. 12 V), and smaller footprint-making it uniquely suited for space-constrained, high-speed CAN-FD nodes requiring precise signal fidelity and AEC-Q101 reliability.

FAQ
What is the maximum operating temperature for PESD2CANFD24VQC-QZ?
The device supports continuous operation from −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. This rating aligns with under-hood ECU environments and enables placement near heat sources without thermal derating of clamping performance.
Can PESD2CANFD24VQC-QZ protect both CANH and CANL simultaneously?
Yes - pins 1 and 2 serve as independent cathodes for CANH and CANL lines respectively, while pin 3 provides a shared cathode reference. This configuration allows simultaneous, matched clamping of both differential lines without cross-talk or imbalance.
Is side-wettable flank inspection supported for this package?
Yes - the DFN1412D-3 (SOT8009) package features side-wettable flanks with ≤0.02 mm protrusion, enabling automated optical inspection (AOI) of solder fillets on all three terminals, a requirement for IATF 16949-compliant automotive assembly lines.
How does its 6 pF capacitance affect CAN-FD timing budgets?
At 6 pF per line, the device adds <10 ps of rise-time degradation on 5 Mbps CAN-FD signals (200 ns bit time), well within ISO 11898-2 timing margins. Measured eye diagrams show >92% opening retention, confirming compatibility with high-speed physical layer compliance testing.
