Product details
Overview
PESD2CANFD24U-QB from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1110D-3 (SOT8015) package, designed to safeguard CAN-FD and CAN bus lines against IEC 61000-4-2 ±15 kV and ISO 10605 ±15 kV transients. It features 24 V reverse standoff voltage, 33 V clamping at 1 A, and ultra-low 3.5 pF capacitance for minimal signal distortion on high-speed in-vehicle networks.
For engineers reviewing the PESD2CANFD24U-QB datasheet, PESD2CANFD24U-QB pinout, PESD2CANFD24U-QB application, or PESD2CANFD24U-QB equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, side-wettable flank compatibility with automated optical inspection (AOI), and matched capacitance (<0.5% ΔCd/Cd) across dual channels for differential bus integrity.
Technical Context
This device implements two independent, common-cathode-connected TVS diodes in a single ultra-compact leadless package - enabling simultaneous protection of CANH and CANL lines without cross-talk or imbalance. Its low dynamic resistance (1 Ω) and fast response (<1 ns) ensure effective clamping during sub-nanosecond ESD events.
The symmetric V-I characteristics (±25.5 V breakdown, ±33 V clamping at 1 A) and matched diode capacitance (3.2–3.5 pF per channel, ΔCd/Cd ≤ 0.5%) preserve signal integrity on bidirectional 5 Mbps CAN-FD buses while maintaining strict common-mode rejection under transient 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 common-mode range). |
| Clamping Voltage | 33 V at 1 A (8/20 µs) - Limits transient overvoltage to safe levels below CAN transceiver absolute maximum ratings. |
| ESD Rating | ±15 kV IEC 61000-4-2 contact - Meets automotive OEM ESD immunity requirements for connector-level protection. |
| Diode Capacitance | 3.5 pF at 2.5 V reverse - Minimizes signal rise-time degradation on >5 Mbps CAN-FD data links. |
| Capacitance Matching | ≤0.5% ΔCd/Cd - Maintains differential impedance balance critical for EMC compliance and bit-error rate control. |
| Peak Pulse Current | 1.9 A (8/20 µs) - Supports robust surge immunity per IEC 61000-4-5 Level 3 (1 kV line-to-ground). |
| AEC-Q101 Qualified | Qualified for automotive use - Validated for temperature cycling (-55 °C to +150 °C), humidity, and mechanical shock per AEC standard. |
Pinout & Package
DFN1110D-3 (SOT8015) is an ultra-thin, leadless surface-mount package measuring 1.1 mm × 1.0 mm × 0.48 mm with side-wettable flanks for automated solder-joint inspection. Its 0.65 mm pitch and three-terminal layout enable high-density placement near vehicle bus connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to CANH line; forms first ESD clamp path to common cathode (pin 3). |
| 2 | K2 (Cathode 2) | Connects to CANL line; forms second independent ESD clamp path to common cathode (pin 3). |
| 3 | CC (Common Cathode) | Shared cathode node tied to chassis or local ground plane; enables compact dual-diode topology with single return path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Protects both polarities of CANH/CANL simultaneously without external biasing or polarity constraints. |
| Side-Wettable Flanks (SWF) | Enables AOI-compatible solder joint verification - critical for zero-defect automotive manufacturing. |
| Matched Channel Capacitance | ΔCd/Cd ≤ 0.5% ensures <1 ps skew between protected differential signals, preserving CAN-FD timing margins. |
| Low Dynamic Resistance | 1 Ω Rdyn minimizes voltage overshoot during fast-rising ESD pulses (<1 ns rise time). |
| Ultra-Small Footprint | 1.1 mm × 1.0 mm area saves PCB space in tight ECU module layouts near OBD-II or gateway connectors. |
Applications
| CAN-FD Bus Protection | CAN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed (2–5 Mbps) Controller Area Network Flexible Data-Rate interfaces in ADAS domain controllers and battery management systems. IC Role / Device Role / Timing Role: Dual-channel transient voltage suppressor placed directly at the CAN transceiver I/O pins to clamp ESD and coupled surges before signal distortion occurs. Use Value: Enables reliable operation up to 5 Mbps with <0.5% capacitance mismatch - preventing bit errors caused by differential skew during transient events. | Use Scenario: Safeguarding legacy 1 Mbps CAN networks in body control modules, instrument clusters, and HVAC ECUs exposed to frequent connector mating cycles. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp positioned adjacent to the CAN connector to absorb ±15 kV contact ESD without loading the 120 Ω bus termination. Use Value: Maintains bus signal integrity under repeated ESD stress while meeting ISO 11898-2 electrical layer requirements. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Shielding FlexRay communication lines (10 Mbps) in powertrain and chassis control units from ESD-induced protocol errors during vehicle assembly or service. IC Role / Device Role / Timing Role: High-speed transient suppressor with sub-3.5 pF capacitance deployed at FlexRay transceiver inputs to avoid jitter accumulation in deterministic time-triggered networks. Use Value: Preserves <100 ps timing margin on 10 Mbps FlexRay clocks by limiting added capacitance to <3.5 pF per channel. | Use Scenario: Securing Single Edge Nibble Transmission (SENT) sensor outputs (e.g., pressure, temperature) in engine control units against ESD-induced false edge detection. IC Role / Device Role / Timing Role: Low-leakage (1 nA IRM) ESD clamp placed at SENT receiver input to prevent false pulse triggering while maintaining DC accuracy. Use Value: Prevents erroneous nibble interpretation during ESD events due to <1 nA reverse leakage at 24 V standoff - ensuring valid sensor data reporting. |
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 |
|---|---|---|---|
| NUP4201MR6T1G | Higher 45 V clamping at 1 A; 12 pF capacitance; SO-8 package (3.9 mm × 4.9 mm). | Not suitable for CAN-FD >2 Mbps due to excessive capacitance; better for lower-speed LIN or analog sensor lines. | Select only when board space allows larger SO-8 footprint and speed requirements are ≤1 Mbps. |
| TPD2E001DRYR | 3.3 V VRWM; 10 pF capacitance; 0.65 mm pitch DSBGA-6 package; not AEC-Q101 qualified. | Designed for consumer USB/USB-C ports; lacks automotive temperature rating and ESD robustness for vehicle harness environments. | Reject for automotive use - insufficient junction temperature rating (125 °C max) and unqualified for AEC-Q101 stress tests. |
Compared with NUP4201MR6T1G and TPD2E001DRYR, PESD2CANFD24U-QB uniquely combines AEC-Q101 qualification, 3.5 pF capacitance, and 24 V standoff in a 1.1 mm × 1.0 mm SWF package - making it the only option validated for production CAN-FD systems requiring both high-speed signal fidelity and zero-defect manufacturability.

FAQ
What is the maximum operating temperature for PESD2CANFD24U-QB?
The device is rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to +150 °C, fully compliant with AEC-Q101 thermal stress requirements for under-hood automotive applications such as engine control modules and transmission control units.
Can PESD2CANFD24U-QB protect both CANH and CANL simultaneously?
Yes - its pin 1 (K1) and pin 2 (K2) connect independently to CANH and CANL, while pin 3 (CC) serves as the shared cathode node tied to ground. This configuration provides true bidirectional, symmetrical clamping for both lines without interaction or imbalance.
Is the 3.5 pF capacitance measured per channel or total?
The 3.5 pF value is the typical capacitance measured per channel - i.e., between pin 1 and pin 3 (K1–CC) and between pin 2 and pin 3 (K2–CC) - with matching tolerance of ≤0.5% difference, ensuring balanced loading on differential CAN-FD pairs.
Does PESD2CANFD24U-QB require external biasing or direction selection?
No - it operates as a passive, bidirectional ESD suppressor with no external control signals, power supply, or polarity configuration needed. Its intrinsic diode structure automatically clamps positive and negative transients on both channels relative to the common cathode.
