Product details
Overview
PESD2CANFD27LT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed specifically for CAN FD bus lines. It provides 30 kV IEC 61000-4-2 contact ESD immunity, 230 W peak pulse power (8/20 µs), and clamps at 41 V under 5 A surge current - enabling robust protection of high-speed CAN transceivers in vehicle networking systems.
For engineers reviewing the PESD2CANFD27LT-QR datasheet, PESD2CANFD27LT-QR pinout, PESD2CANFD27LT-QR application, or PESD2CANFD27LT-QR equivalent, this device is selected for CAN FD physical layer transient suppression where low capacitance (25–30 pF), ultra-low leakage (<1 nA), and AEC-Q101 qualification are mandatory design requirements.
Technical Context
This dual-cathode bidirectional TVS diode integrates two independent ESD protection paths between CANH/CANL and a common cathode (Pin 3), forming a symmetric clamp topology optimized for differential bus signaling. Its 24 V reverse standoff voltage (VRWM) aligns with CAN FD's 2.5–5 V common-mode range while maintaining margin against bus overvoltage.
The device uses silicon avalanche junctions to achieve fast response (<1 ns), low clamping voltage (34 V at 1 A, 41 V at 5 A), and stable performance across −55 °C to +150 °C ambient - validated per IEC 61000-4-5 (surge) and MIL-STD-883 HBM (16 kV).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V reverse standoff voltage - ensures no conduction during normal CAN FD bus operation up to ±24 V common-mode transients. |
| VCL @ 5 A | 41 V clamping voltage (8/20 µs) - limits transient energy delivered to downstream CAN transceiver, preventing latch-up or damage. |
| Cd | 25–30 pF capacitance at 1 MHz - minimizes signal distortion on CAN FD buses operating up to 5 Mbps without degrading edge integrity. |
| IRM | <1 nA leakage at 24 V - avoids DC loading of bias networks and preserves bus termination accuracy in split-termination architectures. |
| PPP | 230 W peak pulse power (8/20 µs) - sustains automotive-level surge events including load dump coupling and ISO 7637-3 pulses. |
| ESD Rating | 30 kV IEC 61000-4-2 contact discharge - exceeds automotive OEM requirements for connector-level ESD immunity. |
| AEC-Q101 | Qualified per stress test standard for discrete semiconductors - validates reliability for under-hood and body-control module deployment. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads; 1.9 mm × 1.1 mm footprint, 1.0 mm max height, gull-wing leads for reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode for CANH line | Connects to CANH via shortest possible trace; forms low-inductance path to ground during ESD event on high-side bus line. |
| 2 | Cathode for CANL line | Connects to CANL; enables symmetrical clamping of differential transients without skew or imbalance in protection response. |
| 3 | Common anode (ground reference) | Must connect directly to low-impedance chassis or system ground plane - critical for effective transient return path and clamping voltage control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line CAN FD protection | Single SOT23 device protects both CANH and CANL with matched clamping characteristics - eliminates component count vs. discrete diodes. |
| Low capacitance (25–30 pF) | Preserves signal integrity on 5 Mbps CAN FD buses by limiting rise-time degradation and reflection-induced jitter. |
| Ultra-low leakage (<1 nA) | Maintains precise 120 Ω differential termination and split-bias network stability over temperature and lifetime. |
| AEC-Q101 qualified | Validated for 150 °C junction temperature, thermal cycling, and humidity testing - suitable for engine bay and ADAS ECU placement. |
| IEC 61000-4-5 compliant | Withstands 5 A surge (8/20 µs) per line - meets ISO 16750-2 Pulse 5a/b for automotive power supply transients coupled onto data lines. |
Applications
| Automotive CAN FD Gateway | ADAS Camera Link Protection |
|---|---|
|
Use Scenario: High-speed communication between domain controllers and central gateway ECUs using CAN FD up to 5 Mbps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN bus ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-2M3 | Lower VRWM (5.5 V), higher Cd (110 pF), unidirectional configuration | Designed for 5 V logic-level interfaces, not automotive CAN bus voltage margins | Select only for non-automotive 3.3/5 V CAN-like buses with relaxed speed and voltage requirements. |
| TPD2E001DRYR | 2-channel unidirectional, 5.5 V VRWM, 12 pF Cd, no AEC-Q101 qualification | Targeted at consumer USB/UART ESD protection, lacks surge rating and automotive temp range | Not suitable for CAN FD; use only in non-automotive, low-voltage, low-speed serial interfaces. |
Compared with ESDALC6V1-2M3 and TPD2E001DRYR, PESD2CANFD27LT-QR uniquely delivers 24 V standoff, 25–30 pF capacitance, and AEC-Q101 validation - making it the only drop-in solution for production automotive CAN FD nodes requiring full ISO 11898-2/3 compliance.

FAQ
What is the maximum operating temperature for PESD2CANFD27LT-QR?
The device supports junction temperatures up to 150 °C and ambient operating range from −55 °C to +150 °C, verified per AEC-Q101 thermal cycling and high-temperature operating life tests - enabling direct placement near power stages or under-hood ECUs without derating.
Does PESD2CANFD27LT-QR support CAN FD data rates up to 5 Mbps?
Yes - its 25–30 pF capacitance and sub-1 ns response time preserve signal integrity on 5 Mbps CAN FD buses, as confirmed by eye diagram testing in Nexperia's application note AN11117; layout best practices (short traces, ground plane) are required to maintain timing margins.
How is the common cathode (Pin 3) connected in a typical CAN FD layout?
Pin 3 must be tied directly to a low-inductance system ground plane - not via series resistors or shared return paths - to ensure clamping voltage remains stable during 5 A surges; Nexperia recommends ≥3 ground vias within 2 mm of Pin 3 for optimal performance.
Is PESD2CANFD27LT-QR compatible with standard SOT23 reflow profiles?
Yes - it complies with JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak reflow temperatures up to 260 °C for 30 seconds; the SOT23 footprint matches IPC-7351B generic outline with 0.95 mm pitch and 0.6 mm pad width.
