Product details
Overview
PESD2CANFD27U-QB from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1110D-3 (SOT8015) package, designed for bidirectional transient suppression on CAN-FD and CAN bus lines. It delivers 27 V reverse standoff voltage, 34 V clamping at 1 A, 4.0 pF capacitance, 15 kV IEC 61000-4-2 ESD rating, and AEC-Q101 qualification - enabling robust signal integrity in high-speed in-vehicle networks.
For engineers reviewing the PESD2CANFD27U-QB datasheet, PESD2CANFD27U-QB pinout, PESD2CANFD27U-QB application, or PESD2CANFD27U-QB equivalent, key selection criteria include low clamping voltage under 8/20 µs surge, sub-4 pF capacitance for minimal signal distortion on 5 Mbps CAN-FD buses, side-wettable flank compatibility with automated optical inspection (AOI), and common-cathode dual-diode topology for space-constrained automotive PCB layouts.
Technical Context
This device implements a dual unidirectional TVS diode configuration with a shared cathode (pin 3), where pins 1 and 2 serve as independent anodes for two protected lines. Its ultra-low 4.0 pF capacitance is measured at 1 MHz and ±2.5 V reverse bias, ensuring <0.5% signal rise-time degradation on 5 Mbps CAN-FD differential pairs.
The clamping behavior is characterized by 34 V typical (max 45 V) at 1 A 8/20 µs pulse, with dynamic resistance of 1.3 Ω, enabling fast energy diversion while maintaining bus voltage compliance during ESD events up to ±15 kV per IEC 61000-4-2 and ISO 10605 (150 pF / 330 Ω).
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 | 34 V @ 1 A, 8/20 µs - Limits transients below CAN transceiver absolute max rating (typically 40–45 V) |
| Diode Capacitance | 4.0 pF @ 1 MHz, –2.5 V - Preserves signal integrity on 5 Mbps CAN-FD with <1% timing skew |
| ESD Rating | ±15 kV IEC 61000-4-2 contact discharge - Meets automotive OEM ESD immunity requirements |
| Peak Pulse Current | 1.8 A @ 8/20 µs - Handles IEC 61000-4-5 level 3 surges (1 kV line-to-ground) with margin |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validated for under-hood temperature cycling (–55 °C to +150 °C) |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin (0.48 mm height) surface-mount package with side-wettable flanks for automated solder-joint inspection. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm, 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Common return path for ESD current from first protected line (e.g., CANH) |
| 2 | K2 (Cathode of Diode 2) | Common return path for ESD current from second protected line (e.g., CANL) |
| 3 | CC (Common Cathode) | Shared ground reference terminal - must connect directly to low-inductance chassis or power ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single footprint | Reduces PCB area by >40% vs. two discrete 0201 TVS diodes; eliminates layout mismatch between CANH/CANL paths |
| Side-wettable flanks (SWF) | Enables AOI-compatible solder-joint verification - critical for zero-defect automotive manufacturing |
| Ultra-low capacitance matching | ΔCd/Cd ≤ 0.5% - Ensures balanced differential impedance and common-mode rejection on CAN-FD buses |
| Low dynamic resistance | 1.3 Ω - Minimizes voltage overshoot during fast ESD transients (<1 ns rise time) |
| Automotive thermal robustness | Rated junction temperature up to +150 °C - Sustains operation near engine control units and ADAS ECUs |
Applications
| CAN-FD Bus Protection | CAN Bus Protection |
|---|---|
|

Use Scenario: Engine knock sensor transmitting analog waveform via SENT protocol to ECU. IC Role / Device Role / Timing Role: Single-line ESD protection on SENT data line (open-drain, 12 V supply referenced). Use Value: Blocks ESD-induced false edge detection on SENT pulse train while preserving <1 µs pulse width resolution. |
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 5.5 pF capacitance; 33 V clamping; SO-8 package (3.9 mm × 4.9 mm) | Not suitable for space-constrained CAN-FD modules; requires larger PCB real estate and longer trace routing | Select when board-level AOI is not required and higher capacitance is acceptable for <1 Mbps CAN. |
| TPD2E007DRYR | Lower 24 V VRWM; 3.5 pF capacitance; 3-pin X2SON package (1.0 mm × 0.6 mm) | Lacks AEC-Q101 qualification; rated only for industrial temp range (–40 °C to +85 °C) | Acceptable for non-safety-critical infotainment interfaces but not for powertrain or ADAS systems. |
Compared with NUP4202MR6T1G and TPD2E007DRYR, PESD2CANFD27U-QB uniquely combines AEC-Q101 qualification, 4.0 pF capacitance, side-wettable flanks, and DFN1110D-3 size - making it the only option qualified for production CAN-FD modules requiring zero-defect solder joint inspection and 5 Mbps signal fidelity.

FAQ
What is the maximum recommended PCB trace length between PESD2CANFD27U-QB and the connector?
Per Nexperia application guidance, the trace length from the protected line (pin 1 or 2) to the connector should be ≤3 mm, and the common-cathode (pin 3) ground connection must route directly to a low-inductance ground plane with no vias or necking. Longer traces increase inductance, degrading clamping performance during sub-nanosecond ESD events.
Can PESD2CANFD27U-QB protect both CANH and CANL simultaneously in a standard CAN transceiver interface?
Yes - pins 1 and 2 connect to CANH and CANL respectively, while pin 3 connects to the transceiver's ground-referenced protection node. The dual-diode architecture provides symmetrical clamping for both lines relative to ground, supporting standard ISO 11898-2 compliant CAN physical layers without additional components.
Is the 4.0 pF capacitance specified differentially or single-ended?
The 4.0 pF value is measured single-ended: from pin 1 to pin 3 and pin 2 to pin 3, each at 1 MHz and –2.5 V reverse bias. Differential capacitance (between pins 1 and 2) is not specified, but ΔCd/Cd ≤ 0.5% ensures matched single-ended capacitance - critical for maintaining CAN bus common-mode rejection ratio (CMRR).
Does PESD2CANFD27U-QB require external series resistors for CAN-FD compliance?
No - the device is designed for direct placement between connector and transceiver, with no external series resistors needed. Its 1.3 Ω dynamic resistance and 34 V clamping ensure compliance with ISO 11898-2 bus voltage limits during transients, and its 4.0 pF capacitance avoids resonance issues up to 20 MHz.
