Product details
Overview
PESD2CANFD36LQC-Q from Nexperia is a bidirectional ESD protection diode in a DFN1412D-3 (SOT8009) package, designed for dual-line CAN-FD bus protection in automotive systems. It delivers 36 V reverse standoff voltage, 42 V typical clamping at 1 A, and 10 pF capacitance - enabling robust transient suppression without signal integrity degradation on high-speed vehicle networks.
For engineers reviewing the PESD2CANFD36LQC-Q datasheet, PESD2CANFD36LQC-Q pinout, PESD2CANFD36LQC-Q application, or PESD2CANFD36LQC-Q equivalent, this device is selected specifically for CAN-FD and FlexRay bus line protection where low clamping, AEC-Q101 qualification, and side-wettable flanks for automated optical inspection are mandatory design requirements.
Technical Context
This dual-cathode ESD protector uses two back-to-back diodes sharing a common cathode (Pin 3), forming a symmetrical bidirectional clamp between Pins 1–3 and 2–3. Its architecture supports simultaneous protection of two independent data lines - such as CANH and CANL - with matched capacitance (±0.5%) and identical clamping behavior under ±16 A TLP pulses.
The device complies with IEC 61000-4-2 (±20 kV contact), ISO 10605 (±20 kV, 330 pF/330 Ω), and ISO 7637-2 Pulse 3a/3b (±300 V), meeting stringent automotive EMC requirements. Its 1.1 Ω dynamic resistance ensures rapid energy diversion during sub-nanosecond ESD events while maintaining <1 nA leakage at 36 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - defines maximum continuous operating voltage before conduction begins on CAN-FD bus lines |
| Clamping Voltage | 52 V at 16 A (TLP) - limits transient overvoltage seen by downstream CAN transceiver during ESD stress |
| Diode Capacitance | 10 pF at 1 MHz / 0 V - preserves signal integrity on >5 Mbps CAN-FD buses with minimal rise-time degradation |
| ESD Rating | ±20 kV IEC 61000-4-2 - meets automotive OEM immunity requirements for human-body-model discharge |
| Peak Pulse Current | 2.9 A (8/20 µs) - withstands surge events per IEC 61000-4-5 Level 3 without failure |
| Dynamic Resistance | 1.1 Ω - enables fast response and low-voltage overshoot during nanosecond-scale ESD transients |
| Leakage Current | 1 nA at 36 V - prevents DC loading or battery drain in always-on vehicle networks |
Pinout & Package
DFN1412D-3 (SOT8009) is an ultra-small, leadless surface-mount package measuring 1.4 mm × 1.2 mm × 0.48 mm with side-wettable flanks for automated solder-joint inspection. Its 0.8 mm pitch and three-terminal layout support high-density placement near connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to first protected line (e.g., CANH); forms one half of bidirectional clamp to common cathode |
| 2 | Cathode (Diode 2) | Connects to second protected line (e.g., CANL); forms second half of symmetrical dual-line protection path |
| 3 | Common Cathode | Shared return node tied to chassis or local ground; completes both clamping paths with matched impedance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low clamping voltage | 42 V typical at 1 A - reduces stress on CAN transceivers rated for 45 V absolute max |
| Matched diode capacitance | ±0.5% inter-channel variation - maintains differential signal balance on CANH/CANL pairs |
| AEC-Q101 qualified | Rated for −55 °C to +150 °C operation - validated for under-hood and body-control module environments |
| Side-wettable flanks | 0.02 mm max protrusion - enables AOI-compatible solder-joint verification in automated SMT lines |
| Low leakage current | 1 nA at VRWM - eliminates measurable power loss in 24 V truck network standby modes |
Applications
| Automotive CAN-FD Bus Protection | Truck 24 V Network ESD Guarding |
|---|---|
|
Use Scenario: Protecting high-speed CAN-FD communication lines (up to 5 Mbps) in ADAS domain controllers against ESD coupling through OBD-II or sensor connectors. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, clamping ESD pulses before they reach the CAN transceiver. Use Value: Prevents transceiver latch-up or permanent damage while preserving signal edge fidelity via 10 pF capacitance and matched diode pair. |
Use Scenario: Safeguarding 24 V power-distribution networks in commercial vehicles against ESD events during service or harness mating. IC Role / Device Role / Timing Role: Dual-line protector deployed across supply rails or LIN/CAN auxiliary lines in cab modules exposed to technician handling. Use Value: Enables compliance with ISO 10605 Class C (20 kV) without derating, supporting long-term reliability in harsh truck environments. |
| FlexRay Bus Transient Suppression | SENT Sensor Interface Protection |
|
Use Scenario: Securing FlexRay physical layer in powertrain control units where deterministic timing requires sub-100 ns clamping response. IC Role / Device Role / Timing Role: Low-dynamic-resistance (1.1 Ω) clamp ensuring minimal voltage overshoot during 100 ns TLP pulses on FlexRay differential pairs. Use Value: Maintains FlexRay's 10 Mbit/s timing margin by limiting transient-induced jitter and preventing receiver desynchronization. |
Use Scenario: Shielding SENT (Single Edge Nibble Transmission) sensor interfaces in engine management systems from ESD induced during sensor replacement. IC Role / Device Role / Timing Role: Low-capacitance (10 pF) protector placed inline with SENT data line to avoid pulse-width distortion in 125 kHz carrier modulation. Use Value: Preserves SENT's 1-bit-per-nibble accuracy by avoiding RC time-constant-induced duty-cycle shift at the microcontroller input. |
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 |
|---|---|---|---|
| ESDALC6V1-1M2 | Higher clamping (65 V at 1 A), 12 pF capacitance, same DFN1412D-3 package | Less suitable for 5 Mbps CAN-FD due to higher capacitance and slower response | Select when protecting lower-speed LIN or legacy CAN (125 kbps) with higher system voltage margin |
| TPD2E001DRYR | Unidirectional configuration, 5 V VRWM, 0.8 pF capacitance, 6-pin SON package | Requires separate ground-referenced placement per line; not pin-compatible or functionally equivalent | Choose only for non-automotive, low-voltage (≤5.5 V) applications requiring ultra-low capacitance |
Compared with ESDALC6V1-1M2 and TPD2E001DRYR, PESD2CANFD36LQC-Q uniquely combines 36 V standoff, 10 pF capacitance, and dual-cathode symmetry - making it the only AEC-Q101-qualified option optimized for CAN-FD's speed, voltage, and layout constraints.

FAQ
What is the maximum junction temperature rating for PESD2CANFD36LQC-Q?
The absolute maximum junction temperature is 150 °C, verified per AEC-Q101 stress testing. This allows operation in under-hood ECUs and body control modules where ambient temperatures reach 125 °C, provided PCB thermal design maintains junction-to-case resistance below 120 K/W.
Can PESD2CANFD36LQC-Q protect both CANH and CANL simultaneously with a single device?
Yes - its dual-cathode architecture (Pins 1 and 2 as individual cathodes, Pin 3 as common cathode) enables simultaneous, symmetrical clamping of both differential lines to ground. This eliminates need for two discrete diodes and ensures matched transient response on CANH/CANL.
Is the 10 pF capacitance measured between each anode and the common cathode?
Yes - capacitance is specified as 10 pF (typical) between Pin 1 and Pin 3, and identically between Pin 2 and Pin 3, at 1 MHz and 0 V bias. The matching tolerance is ±0.5%, ensuring balanced differential impedance on high-speed buses.
Does PESD2CANFD36LQC-Q meet ISO 7637-2 Pulse 2a requirements?
Yes - it withstands +65 V Pulse 2a (inductive load dump simulation) per ISO 7637-2, confirmed in characterization. This makes it suitable for protecting CAN transceivers in powertrain and chassis modules subject to relay-switching transients.
