Product details
Overview
PESD2CANFD27L-TR from Nexperia is a dual-channel automotive ESD protection diode in SOT23 package, designed for CAN-FD and CAN bus lines with 27 V reverse standoff voltage, 31 V clamping at 1 A, 10 pF capacitance, AEC-Q101 qualification, and 175 °C junction temperature rating.
For engineers reviewing the PESD2CANFD27L-TR datasheet, PESD2CANFD27L-TR pinout, PESD2CANFD27L-TR application, or PESD2CANFD27L-TR equivalent, this device supports high-speed in-vehicle network protection where low capacitance, precise clamping, and automotive-grade reliability are critical for CAN-FD signal integrity and ESD immunity compliance.
Technical Context
This bidirectional dual-diode array uses common-cathode topology (pins 1 & 2 as individual cathodes, pin 3 as shared cathode) to protect two differential bus lines-e.g., CANH and CANL-against IEC 61000-4-2 (±30 kV contact) and ISO 10605 (±30 kV, 150 pF/330 Ω) transients. Its 9–10 pF typical capacitance ensures minimal signal distortion on 5 Mbps CAN-FD links.
The device operates across –55 °C to +175 °C ambient, with dynamic resistance of 0.55 Ω and clamping voltage tightly specified at 31 V (typ) / 42 V (max) under 8/20 µs surge (1 A), enabling robust transient suppression without compromising bus timing margins or receiver sensitivity.
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 common-mode, ±40 V fault tolerance) |
| Clamping Voltage | 31 V (typ) at 1 A, 8/20 µs - Limits transient voltage to safe level for CAN transceivers rated ≤ 40 V abs max |
| Diode Capacitance | 10 pF - Preserves signal edge integrity up to 5 Mbps CAN-FD data rates with <0.5% rise-time degradation |
| ESD Rating | ±30 kV IEC 61000-4-2 contact - Meets automotive OEM requirements for dashboard, body control, and ADAS module interfaces |
| Junction Temperature | 175 °C - Supports placement near powertrain ECUs and under-hood modules without derating |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validated for automotive production use without additional qualification |
| Peak Pulse Current | 3.9 A (8/20 µs) - Handles ISO 7637-3 coupled surges and load-dump induced transients on protected lines |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height, optimized for automated placement and reflow soldering on automotive PCBs.
| 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 coordinated clamping for differential bus pairs |
| 3 | CC (Common Cathode) | Shared return path to ground or chassis; establishes reference for bidirectional clamping on both lines simultaneously |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single SOT23 | Reduces board space by 50% vs. two discrete TVS devices while maintaining matched capacitance (<0.5% ΔCd/Cd) |
| Ultra-low 10 pF capacitance | Minimizes signal reflection and jitter on high-speed CAN-FD buses operating up to 5 Mbps |
| 31 V clamping at 1 A | Keeps transient voltage below absolute maximum ratings of industry-standard CAN transceivers (e.g., TJA1042, SN65HVD256) |
| AEC-Q101 qualification | Validates reliability for 15+ year automotive service life under thermal cycling, humidity, and mechanical shock |
| 175 °C junction rating | Enables direct mounting on engine control units and transmission control modules without thermal derating |

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 |
|---|---|---|---|
| NUP4201MR6T1G | Higher 15 pF capacitance; 33 V clamping; 24 V VRWM; SO-8 package | Requires larger PCB area; less suitable for >2 Mbps CAN-FD due to higher signal loading | Select when board space allows and lower VRWM aligns with system-level fault margin strategy |
| TPD2E001DRYR | Lower 1.5 pF capacitance; 24 V VRWM; 3.3 V logic-compatible; 6-pin X2SON | Designed for USB/low-voltage data lines-not AEC-Q101 qualified or rated for 175 °C | Reject for automotive under-hood or safety-critical CAN applications; consider only for non-automotive industrial CAN nodes |
Compared with NUP4201MR6T1G and TPD2E001DRYR, PESD2CANFD27L-TR uniquely balances 10 pF capacitance, 27 V standoff, AEC-Q101 qualification, and SOT23 footprint-making it the only option validated for production CAN-FD systems requiring zero derating at 125 °C ambient.

FAQ
What is the maximum peak pulse current rating for PESD2CANFD27L-TR?
The device is rated for 3.9 A peak pulse current under 8/20 µs waveform per IEC 61000-4-5. This value applies to stress applied between either pin 1 or pin 2 and pin 3, and reflects the maximum non-repetitive surge the diode can safely clamp without parametric shift or failure.
Does PESD2CANFD27L-TR support bidirectional transient suppression?
Yes-it is a bidirectional dual-diode array with symmetrical clamping behavior. Each channel (pin 1–3 and pin 2–3) clamps both positive and negative transients, verified by TLP testing showing ±29.9 V clamping at 30 ns for ±8 kV ESD pulses per IEC 61000-4-2.
How does the common-cathode configuration affect PCB layout?
The shared cathode (pin 3) requires a low-inductance, low-impedance connection to system ground or chassis. Layout must minimize trace length from pin 3 to ground plane, avoid daisy-chaining with other protection devices, and maintain symmetric routing from pins 1 and 2 to their respective bus lines to preserve differential impedance.
Is PESD2CANFD27L-TR compatible with lead-free reflow processes?
Yes-the SOT23 package is qualified for standard lead-free reflow profiles (J-STD-020, peak temperature 260 °C). The recommended solder land pattern matches JEDEC MS-012AC, with 0.6 mm pad width and 0.7 mm length per terminal, ensuring reliable wetting and mechanical strength.
