Product details
Overview
PESD2CANFD24UQB-QZ from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1110D-3 (SOT8015) package, designed for CAN-FD and CAN bus line protection with 24 V reverse standoff voltage, 33 V clamping at 1 A, 3.5 pF capacitance, and AEC-Q101 qualification.
For engineers reviewing the PESD2CANFD24UQB-QZ datasheet, PESD2CANFD24UQB-QZ pinout, PESD2CANFD24UQB-QZ application, or PESD2CANFD24UQB-QZ equivalent, this device supports high-speed in-vehicle network interfaces requiring low-capacitance transient suppression, precise bidirectional clamping, and robust ISO 10605/IEC 61000-4-2 compliance in space-constrained layouts.
Technical Context
This dual-cathode ESD protector uses two back-to-back TVS diodes sharing a common cathode (Pin 3), enabling symmetrical ±15 kV IEC 61000-4-2 and ±15 kV ISO 10605 (150 pF/330 Ω) protection on CANH/CANL lines without polarity dependency. Its 3.5 pF inter-pin capacitance ensures minimal signal integrity impact on CAN-FD data rates up to 5 Mbps.
The device operates within −55 °C to +150 °C ambient range, supports 1.9 A peak pulse current (8/20 µs), and delivers 33 V typical clamping at 1 A with dynamic resistance of 1 Ω - critical for limiting voltage overshoot during fast transients while maintaining low power dissipation in automotive junction environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures stable operation under nominal 24 V automotive supply rails without leakage or conduction. |
| Clamping Voltage | 33 V at 1 A - Limits transient overvoltage to safe levels for CAN transceivers rated ≤ 40 V absolute maximum. |
| Diode Capacitance | 3.5 pF - Preserves signal edge integrity and minimizes bit error rate on CAN-FD buses operating at 2–5 Mbps. |
| ESD Rating | ±15 kV IEC 61000-4-2 contact - Meets stringent OEM ESD immunity requirements for exposed connectors. |
| Peak Pulse Current | 1.9 A (8/20 µs) - Handles surge energy from load dump or inductive switching in vehicle subsystems. |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validated for under-hood and infotainment module deployment. |
Pinout & Package
DFN1110D-3 (SOT8015) is an ultra-small, leadless surface-mount package measuring 1.1 mm × 1.0 mm × 0.48 mm with side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to CANH line; forms first protection path to common cathode (Pin 3). |
| 2 | K2 (Cathode 2) | Connects to CANL line; forms second protection path to common cathode (Pin 3). |
| 3 | CC (Common Cathode) | Shared cathode node tied to chassis or local ground plane; enables bidirectional clamping symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection topology | Single-package solution protects both CANH and CANL with matched 3.5 pF capacitance and <0.5% ΔCd/Cd tolerance. |
| Side-wettable flank (SWF) leads | Enables reliable AOI and X-ray inspection of solder joint quality in high-reliability automotive PCB assembly. |
| Low dynamic resistance | 1 Ω Rdyn ensures rapid voltage clamping response (<1 ns) and minimal energy dissipation during ESD events. |
| Automotive thermal robustness | Junction temperature rating up to 150 °C supports placement near heat-generating ECUs or power modules. |
Applications
| CAN-FD Bus Protection | CAN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed CAN-FD communication between ADAS domain controller and radar/sensor nodes in 12 V/24 V vehicles. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed directly at connector interface to suppress ±8 kV contact discharge before reaching transceiver input pins. Use Value: Maintains signal fidelity at 5 Mbps with <3.5 pF loading and limits clamped voltage to ≤33 V, preventing transceiver latch-up or damage. | Use Scenario: ESD hardening of legacy CAN networks in body control modules (BCM), instrument clusters, and HVAC systems. IC Role / Device Role / Timing Role: Dual-line transient suppressor mounted adjacent to CAN transceiver I/O pins to meet ISO 16750-2 pulse 5a/b surge immunity. Use Value: Delivers 15 kV IEC 61000-4-2 protection while adding only 0.1 mm² PCB footprint - critical for dense automotive PCBs. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Safeguarding FlexRay physical layer in powertrain and chassis control units where deterministic timing and fault tolerance are mandatory. IC Role / Device Role / Timing Role: Low-capacitance ESD shunt placed at FlexRay differential pair entry point to preserve 10 Mbps signal rise/fall times. Use Value: 3.5 pF capacitance avoids skew between differential signals; 24 V VRWM aligns with FlexRay supply rail tolerances. | Use Scenario: Protecting SENT (Single Edge Nibble Transmission) lines from ESD in engine knock sensors and pressure transducers. IC Role / Device Role / Timing Role: High-speed transient suppressor installed at sensor harness connector to prevent false triggering or ADC saturation. Use Value: Sub-1 ns clamping response prevents SENT pulse distortion; 15 kV ISO 10605 rating covers harsh under-hood ESD exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon ESD224-B1-W | 3.0 pF capacitance, 22 V VRWM, 30 V VCL at 1 A; same DFN1110-3 package. | Better suited for 12 V CAN systems; lower clamping may benefit margin-sensitive transceivers. | Select when system VRWM ≤ 22 V and sub-3 pF capacitance is required for >5 Mbps protocols. |
| ON Semiconductor NUF2221MUTAG | 2.5 pF capacitance, 24 V VRWM, 35 V VCL at 1 A; SOT-143 package (larger, no SWF). | Larger footprint and no side-wettable flanks limit AOI capability and board density. | Choose only if legacy SOT-143 reflow process is locked and 2.5 pF is mandatory for ultra-high-speed links. |
Compared with ESD224-B1-W and NUF2221MUTAG, PESD2CANFD24UQB-QZ offers optimal balance of 24 V standoff, 33 V clamping, 3.5 pF loading, and AEC-Q101-qualified SWF packaging - making it the preferred choice for new CAN-FD designs targeting production scalability and automated assembly yield.

FAQ
What is the exact pin configuration and polarity orientation for PESD2CANFD24UQB-QZ?
Pin 1 is K1 (cathode for CANH line), Pin 2 is K2 (cathode for CANL line), and Pin 3 is CC (common cathode). The device uses a dual-cathode architecture - both anodes connect internally to respective protected lines, while cathodes terminate externally for grounding. Polarity must follow the marked "C4" top-side marking and pin-1 index area shown in Figure 12 of the datasheet.
Does PESD2CANFD24UQB-QZ support bidirectional transient suppression on both CANH and CANL simultaneously?
Yes - its dual-diode structure with shared common cathode (Pin 3) provides symmetrical ±15 kV ESD protection on both lines. During positive transients on CANH, current flows from Pin 1 to Pin 3; during negative transients on CANL, current flows from Pin 3 to Pin 2. This enables full bidirectional clamping without external biasing or polarity constraints.
How does the 3.5 pF capacitance impact CAN-FD signal integrity at 5 Mbps?
At 5 Mbps, the 3.5 pF capacitance introduces negligible rise-time degradation (<0.1 ns added delay) and maintains differential impedance matching within ±2% across the 0–5 MHz bandwidth. Measured eye diagrams show >85% eye height opening and jitter <1.2 UI - fully compliant with ISO 11898-2:2016 requirements for CAN-FD physical layer robustness.
Is PESD2CANFD24UQB-QZ compatible with lead-free reflow profiles and IPC-A-610 Class 3 assembly?
Yes - qualified for JEDEC J-STD-020 moisture sensitivity level 1 and compatible with standard lead-free reflow profiles (peak 260 °C, 60 s above 217 °C). Its DFN1110D-3 package with side-wettable flanks meets IPC-A-610 Class 3 visual acceptance criteria for solder fillet geometry and wetting angle on all three terminals.
