Product details
Overview
PESD2CANFD27UT-QR from Nexperia is a dual-channel automotive ESD protection diode in SOT23 package, designed specifically for CAN FD bus lines. It provides 30 kV IEC 61000-4-2 contact ESD protection, clamps at 41 V under 5 A surge (8/20 µs), and delivers 230 W peak pulse power per channel with <1 nA leakage at 24 V standoff voltage.
For engineers reviewing the PESD2CANFD27UT-QR datasheet, PESD2CANFD27UT-QR pinout, PESD2CANFD27UT-QR application, or PESD2CANFD27UT-QR equivalent, this device is selected for high-speed CAN FD transceiver interface protection where low capacitance (25–30 pF), AEC-Q101 qualification, and precise 24 V reverse standoff are critical to signal integrity and system robustness.
Technical Context
This dual-cathode ESD protection array integrates two identical bidirectional TVS diodes sharing a common cathode terminal (Pin 3), enabling symmetrical clamping on CANH and CANL lines relative to ground. Its architecture supports both high-speed CAN (up to 1 Mbps) and CAN FD (up to 5 Mbps) by maintaining low differential capacitance and fast response to sub-nanosecond ESD transients.
The device operates within −55 °C to +150 °C ambient range and is qualified to AEC-Q101, confirming suitability for under-hood automotive environments. Clamping voltage remains stable across temperature, with typical VCL = 34 V at 1 A and 41 V at 5 A, ensuring predictable overvoltage limiting during IEC 61000-4-5 surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN FD bus operation (±2.2 V common-mode, ±40 V fault), preserving signal fidelity. |
| Clamping Voltage | 41 V at 5 A (8/20 µs) - Limits transient voltage seen by downstream CAN transceiver, staying below absolute maximum ratings. |
| Peak Pulse Power | 230 W per diode - Withstands IEC 61000-4-5 surge without degradation, supporting long-term reliability in harsh automotive environments. |
| Diode Capacitance | 25–30 pF at 1 MHz, 0 V - Minimizes signal distortion and timing skew on high-speed CAN FD buses (up to 5 Mbps). |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2 Level 4) - Meets stringent automotive ESD immunity requirements without external shielding. |
| Leakage Current | <1 nA at 24 V - Prevents DC loading of CAN bus termination resistors and avoids false dominant state triggering. |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validates reliability for automotive production use including thermal cycling and humidity testing. |
Pinout & Package
The PESD2CANFD27UT-QR is housed in a standard SOT23 (TO-236AB) plastic surface-mount package measuring 2.9 × 1.3 × 1.0 mm, optimized for automated placement and reflow soldering in high-volume automotive PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Channel A) | Connects to CANH line; forms low-impedance path to common cathode (Pin 3) during positive transients. |
| 2 | Cathode (Channel B) | Connects to CANL line; mirrors Pin 1 behavior for symmetrical bidirectional protection. |
| 3 | Common Cathode | Reference node tied to system ground; enables shared return path for both channels with minimal loop inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel CAN FD protection | Single SOT23 device protects both CANH and CANL lines simultaneously, reducing board space vs. discrete diodes. |
| Low clamping voltage | VCL = 41 V at 5 A ensures transceiver ICs remain within safe operating area during surge events. |
| Ultra-low capacitance | 25–30 pF minimizes rise-time degradation and bit-error rate increase on 5 Mbps CAN FD links. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling, mechanical shock, and humidity resistance. |
| Sub-1 nA leakage | Eliminates DC current draw that could unbalance split-termination networks or trigger false wake-up in low-power modes. |
Applications
| Automotive CAN FD Gateway | ADAS Domain Controller Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive CAN bus ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E007DRYR | Single-channel, 0.5-pF capacitance, 12-V standoff, not AEC-Q101 qualified | Targeted at consumer USB/low-voltage interfaces, not automotive CAN FD | Select only for non-automotive, low-capacitance, single-line applications requiring sub-1-pF performance. |
| SM712-TR | Unidirectional, 100-V standoff, 100-pF capacitance, 600-W surge rating | Designed for RS-485/legacy CAN, lacks bidirectional symmetry and low-CAN-FD-optimized clamping | Use only when higher standoff and legacy protocol compatibility outweigh CAN FD speed and ESD precision requirements. |
Compared with TPD2E007DRYR and SM712-TR, PESD2CANFD27UT-QR uniquely combines AEC-Q101 qualification, 24-V CAN FD–matched standoff, 25–30-pF capacitance, and dual symmetric clamping-making it the only drop-in solution for production automotive CAN FD nodes requiring guaranteed ESD robustness and signal fidelity.

FAQ
What is the maximum operating temperature for PESD2CANFD27UT-QR?
The device supports junction temperatures up to 150 °C and ambient operating range from −55 °C to +150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. This enables direct placement near engine control units or power inverters without derating.
Does PESD2CANFD27UT-QR support CAN FD data rates up to 5 Mbps?
Yes-its 25–30 pF capacitance and sub-1 nA leakage ensure minimal signal distortion and no measurable timing jitter at 5 Mbps, confirmed by Nexperia's application note AN11520 using real CAN FD eye diagrams and bit-error-rate testing.
How is the common cathode (Pin 3) connected in a typical CAN FD layout?
Pin 3 must be connected directly to a low-inductance chassis or power ground plane via shortest possible trace-ideally with multiple vias-to minimize transient return path impedance and prevent ground bounce during ESD events.
Is PESD2CANFD27UT-QR compatible with standard SOT23 pick-and-place equipment?
Yes-it uses industry-standard SOT23 (TO-236AB) footprint with 0.95 mm lead pitch and 2.9 mm × 1.3 mm body dimensions, fully compatible with IPC-7351B land patterns and reflow profiles defined in J-STD-020 for MSL1 handling.
