Product details
Overview
PESD2CANFD27LU-Q from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 (SC-70) package, designed to safeguard CAN-FD and CAN bus lines against ±30 kV IEC 61000-4-2 and ISO 10605 transients. It features 27 V reverse standoff voltage, 31 V clamping at 1 A, and ultra-low 10 pF capacitance for minimal signal distortion in high-speed in-vehicle networks.
For engineers reviewing the PESD2CANFD27LU-Q datasheet, PESD2CANFD27LU-Q pinout, PESD2CANFD27LU-Q application, or PESD2CANFD27LU-Q equivalent, this device is selected for CAN-FD physical layer protection where low capacitance, AEC-Q101 qualification, and common-cathode dual-diode topology are required to maintain signal integrity under ESD stress.
Technical Context
This bidirectional ESD protection device implements two independent avalanche diodes sharing a common cathode (Pin 3), enabling symmetrical clamping on both protected lines (Pins 1 and 2) relative to ground or chassis reference. Its architecture supports simultaneous transient suppression on differential bus pairs without cross-talk or imbalance.
Rated for 175 °C junction temperature and qualified per AEC-Q101, it operates reliably in under-hood automotive environments. The 0.55 Ω dynamic resistance and 8/20 µs pulse handling up to 3.9 A ensure robust surge immunity while maintaining fast response (<1 ns rise time) to ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Ensures no conduction during normal CAN-FD bus operation (±2.5 V differential, ~12 V common-mode). |
| Clamping Voltage | 31 V at 1 A - Limits transient voltage to safe levels below CAN transceiver absolute maximum ratings (typically 40 V). |
| Diode Capacitance | 10 pF - Minimizes signal attenuation and timing skew on 5 Mbps CAN-FD buses. |
| ESD Withstand | ±30 kV IEC 61000-4-2 - Meets automotive OEM requirements for connector-level ESD immunity. |
| Peak Pulse Current | 3.9 A (8/20 µs) - Handles induced surges from load dump or inductive switching in vehicle power domains. |
| Junction Temperature | 175 °C - Supports placement near engine control units or body controllers with high ambient thermal exposure. |
Pinout & Package
Package: SOT323 (SC-70), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body size, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms clamping path to common cathode during positive transients. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); enables independent but referenced clamping for differential pair. |
| 3 | CC (Common Cathode) | Reference node tied to system ground or chassis; defines clamping threshold for both diodes simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line common-cathode topology | Enables compact PCB layout for differential bus protection without separate ground return paths per line. |
| 10 pF typical capacitance | Maintains <1% signal rise-time degradation on 5 Mbps CAN-FD links over 40 m cable runs. |
| AEC-Q101 qualified | Validated for automotive production use including temperature cycling, humidity bias, and mechanical shock testing. |
| 31 V clamping at 1 A | Keeps protected transceiver I/O within safe operating area during ESD events, preventing latch-up or gate oxide damage. |
Applications
| Automotive CAN-FD Bus Protection | Automotive CAN Bus Protection |
|---|---|

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 |
|---|---|---|---|
| NUP4202MR6T1G | Higher 15 pF capacitance; 33 V clamping; SO-8 package (larger footprint) | Targeted at lower-speed CAN (≤1 Mbps); less suitable for CAN-FD due to bandwidth limitation | Select only if board space allows SO-8 and 5 Mbps timing margin is not required. |
| TPD2E001DRYR | Single-channel; 12 pF; 5 V VRWM; not AEC-Q101 qualified | Intended for consumer USB/IO protection; lacks automotive thermal and reliability validation | Not recommended for automotive deployment; use only in non-safety-critical prototyping. |
Compared with NUP4202MR6T1G and TPD2E001DRYR, PESD2CANFD27LU-Q uniquely combines AEC-Q101 qualification, 10 pF capacitance, and 27 V standoff in a space-constrained SOT323 package-making it the only validated option for production CAN-FD systems requiring zero signal integrity compromise.

FAQ
What is the maximum operating temperature for PESD2CANFD27LU-Q?
The device is rated for continuous operation up to 175 °C junction temperature and qualified per AEC-Q101 for automotive under-hood applications. Ambient temperature range is –55 °C to +175 °C, with derating applied above 85 °C ambient per thermal resistance characteristics in the datasheet.
Can PESD2CANFD27LU-Q protect both CANH and CANL simultaneously?
Yes-its common-cathode dual-diode structure (Pins 1 and 2 to Pin 3) enables symmetrical clamping of both lines to the same reference, supporting differential bus protection without requiring separate ground connections or matched layout routing.
Is this device compatible with 5 Mbps CAN-FD data rates?
Yes-the 10 pF typical capacitance and sub-1 ns response time preserve signal integrity at 5 Mbps, as verified in Nexperia's application note AN11122 for CAN-FD layout and transient testing with this part.
Does PESD2CANFD27LU-Q require external biasing or control signals?
No-it is a passive, unidirectional clamping device requiring no power supply, enable pin, or configuration. It operates automatically during overvoltage events, conducting only when line voltage exceeds 27 V standoff level in either polarity.
