Product details
Overview
PESD2CANFD36LT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed to safeguard CAN-FD and FlexRay bus lines against 22 kV IEC 61000-4-2 ESD strikes, with 36 V reverse standoff voltage, 43 V clamping at 1 A, and 10 pF capacitance per channel.
For engineers reviewing the PESD2CANFD36LT-QR datasheet, PESD2CANFD36LT-QR pinout, PESD2CANFD36LT-QR application, or PESD2CANFD36LT-QR equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, low capacitance for high-speed bus integrity, and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual unidirectional TVS configuration with shared cathode (pin 3), enabling independent protection of two differential bus lines-e.g., CANH and CANL-while maintaining matched capacitance (<0.5% ΔCd/Cd) and symmetrical clamping behavior under ±16 A TLP pulses.
Its 36 V VRWM ensures compatibility with 24 V board net systems and CAN-FD transceivers operating up to ±30 V common-mode range; dynamic resistance of 0.8 Ω supports fast transient suppression without signal distortion in >5 Mbps data links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Ensures no conduction during normal 24 V truck system operation or CAN-FD bus idle states. |
| Clamping Voltage (1 A) | 43 V - Limits transient overvoltage to safe levels below CAN transceiver absolute maximum ratings. |
| Clamping Voltage (16 A) | 47 V - Maintains robust protection under severe 8/20 µs surge events per IEC 61000-4-5. |
| Diode Capacitance | 10 pF at 0 V - Preserves signal integrity on CAN-FD buses running up to 5 Mbps with minimal rise-time degradation. |
| ESD Withstand | 22 kV contact discharge per IEC 61000-4-2 - Meets stringent OEM requirements for in-vehicle network port immunity. |
| Junction Temperature Limit | 150 °C - Supports operation in under-hood environments with extended thermal margin. |
| AEC-Q101 Qualified | Yes - Validated for automotive use including temperature cycling, HTRB, and ESD stress per discrete semiconductor standard. |
Pinout & Package
SOT23 plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body; optimized for reflow soldering with defined footprint per Fig. 10.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line (e.g., CANH); forms unidirectional clamp to common cathode. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line (e.g., CANL); enables independent, matched protection path. |
| 3 | CC (common cathode) | Reference node tied to system ground or low-impedance return; defines clamping reference for both channels. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode architecture | Enables compact, space-efficient protection of differential bus pairs without external grounding complexity. |
| Matched diode capacitance (ΔCd/Cd ≤ 0.5%) | Maintains common-mode rejection and skew control critical for CAN-FD timing compliance. |
| Low dynamic resistance (0.8 Ω) | Reduces voltage overshoot during fast ESD events, improving immunity margin beyond IEC 61000-4-2 Level 4. |
| Qualified per AEC-Q101 | Validated for automotive under-hood deployment including temperature cycling, HTGB, and mechanical shock. |
| 10 pF capacitance at 0 V reverse bias | Minimizes insertion loss and reflection on 120 Ω CAN-FD differential pairs up to 5 Mbps. |
Applications
| Automotive CAN-FD Bus Protection | 24 V Truck Network Interface |
|---|---|
|
Use Scenario: ESD protection at OBD-II connector or gateway ECU CAN-FD ports exposed to service technician handling.

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 |
|---|---|---|---|
| ESDALC6V1-2M3 | Lower VRWM (5.5 V), higher Cd (15 pF), same SOT23-3 package | Targeted for 5 V logic-level buses (e.g., USB, I²C), not 24 V CAN-FD | Select only for low-voltage digital interfaces; unsuitable for CAN-FD due to premature conduction at 36 V standoff. |
| TPD2E001DRYR | 3.3 V VRWM, 12 pF Cd, 2-pin SOT-5X3 package, no common cathode | Designed for single-ended data lines (e.g., GPIO, UART), lacks dual-channel symmetry | Requires two devices for differential protection; incompatible with CAN-FD common-mode noise rejection requirements. |
Compared with ESDALC6V1-2M3 and TPD2E001DRYR, PESD2CANFD36LT-QR uniquely delivers 36 V standoff, matched 10 pF capacitance, and integrated common-cathode dual-diode topology-enabling single-device, AEC-Q101-compliant protection of high-speed automotive differential buses without signal skew or layout compromise.

FAQ
What is the maximum peak pulse current rating for PESD2CANFD36LT-QR?
The rated peak pulse current (IPPM) is 3.2 A under 8/20 µs waveform per IEC 61000-4-5. This value is measured from either pin 1 or pin 2 to pin 3 and reflects the device's ability to safely divert surge energy without failure during standardized surge testing.
Is PESD2CANFD36LT-QR compatible with CAN-FD data rates up to 5 Mbps?
Yes-its 10 pF diode capacitance at 0 V and matched capacitance (<0.5% ΔCd/Cd) ensure minimal signal distortion and maintain differential impedance integrity on 120 Ω CAN-FD traces, supporting clean edge transitions required for reliable 5 Mbps operation.
How does the common cathode (pin 3) simplify PCB layout?
Pin 3 serves as the shared reference node for both protection channels, allowing direct connection to a low-inductance ground plane near the connector. This eliminates separate ground paths for each line, reducing loop area and improving common-mode transient rejection in differential bus layouts.
Does PESD2CANFD36LT-QR meet ISO 10605 ESD requirements?
Yes-it achieves 22 kV per ISO 10605 (contact discharge, C = 330 pF/R = 330 Ω and C = 150 pF/R = 330 Ω), verified with ten non-repetitive pulses. This exceeds standard OEM requirements for in-vehicle network port immunity and is documented in Section 8 of the official datasheet.
