Product details
Overview
PESD2CANFD27VQB-QZ from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1110D-3 (SOT8015) package, designed for CAN-FD and CAN bus lines. It delivers 27 V reverse standoff voltage, 33 V clamping at 1 A, 6 pF capacitance, 20 kV IEC 61000-4-2 ESD rating, and AEC-Q101 qualification - enabling robust transient suppression in high-speed vehicle network interfaces.
For engineers reviewing the PESD2CANFD27VQB-QZ datasheet, PESD2CANFD27VQB-QZ pinout, PESD2CANFD27VQB-QZ application, or PESD2CANFD27VQB-QZ equivalent, key selection criteria include bidirectional clamping performance, low capacitance for signal integrity on 5 Mbps CAN-FD buses, side-wettable flank compatibility with automated optical inspection (AOI), and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual unidirectional ESD protection structure with shared cathode (Pin 3), where Pin 1 and Pin 2 serve as independent anodes for two protected lines. Its low dynamic resistance (0.8 Ω) and fast response to sub-nanosecond ESD transients ensure effective clamping before downstream transceivers are stressed.
The 6 pF typical capacitance (measured at 1 MHz, ±2.5 V) and <0.5% capacitance matching between channels preserve differential signal fidelity on CAN-FD buses operating up to 5 Mbps. The 27 V VRWM aligns with 24 V automotive supply rails while maintaining margin above CAN common-mode voltage ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Blocks normal CAN-FD bus voltages (±30 V common-mode range) without leakage conduction |
| Clamping Voltage | 33 V at 1 A (8/20 µs) - Limits transient voltage seen by CAN transceiver I/O pins during surge events |
| Diode Capacitance | 6 pF - Minimizes signal distortion and timing skew on high-speed CAN-FD differential pairs |
| ESD Rating | 20 kV contact discharge (IEC 61000-4-2 & ISO 10605) - Meets automotive OEM ESD immunity requirements |
| Peak Pulse Current | 2.5 A (8/20 µs) - Sustains multi-pulse surge stress without degradation in vehicle harness environments |
| Junction Temperature | 150 °C max - Supports operation in under-hood ECUs with ambient temperatures up to 125 °C |
| AEC-Q101 Qualified | Yes - Validated for automotive use per stress test standard for discrete semiconductors |
Pinout & Package
DFN1110D-3 (SOT8015) ultra-thin leadless package: 1.1 mm × 1.0 mm × 0.48 mm body, 0.65 mm pitch, side-wettable flanks for solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Common-cathode node for first protected line (e.g., CANH); connects to system ground via low-inductance path |
| 2 | K2 (Cathode of Diode 2) | Common-cathode node for second protected line (e.g., CANL); shares ground return with Pin 1 for matched clamping |
| 3 | CC (Common Cathode) | Primary ground connection point - must be routed directly to solid ground plane to minimize clamping loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection topology | Single-package solution for both CANH and CANL lines reduces PCB area vs. discrete diodes and ensures matched electrical characteristics |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated terminals - critical for automotive manufacturing traceability |
| Low capacitance matching | <0.5% ΔCd/Cd between channels - preserves differential signal symmetry and minimizes common-mode conversion on high-speed buses |
| Ultra-low dynamic resistance | 0.8 Ω - Reduces voltage overshoot during fast ESD pulses (t<1 ns rise time), improving protection margin for sensitive transceivers |
| Automotive thermal robustness | Rated for 150 °C junction temperature and qualified per AEC-Q101 - supports placement near heat-generating ECUs without derating |
Applications
| CAN-FD Bus Protection | CAN 2.0 Bus Protection |
|---|---|
Use Scenario: High-speed powertrain control module interfacing with 5 Mbps CAN-FD network in engine control unit (ECU). IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between CAN transceiver I/O pins and connector interface.

IC Role / Device Role / Timing Role: Dual-line ESD clamp mounted adjacent to Deutsch DT04-4P connector on vehicle harness entry point. Use Value: Eliminates need for separate TVS diodes per line, reducing BOM count and ensuring matched clamping response across differential pair. |
| FlexRay Network Protection | SENT Sensor Interface Protection |
Use Scenario: Chassis domain controller with FlexRay A/B channels operating at 10 Mbps in ADAS sensor fusion systems. IC Role / Device Role / Timing Role: Common-cathode dual diode protecting both FlexRay differential lines against ESD coupling from nearby high-voltage actuators. Use Value: 6 pF capacitance avoids bandwidth limitation on 10 Mbps FlexRay signals; 27 V VRWM accommodates FlexRay's ±25 V common-mode range. |
Use Scenario: Engine knock sensor interface using Single Edge Nibble Transmission (SENT) protocol in cylinder head-mounted modules. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on SENT signal line (Pin 1) and VDD line (Pin 2), sharing ground (Pin 3). Use Value: Prevents false triggering of SENT decoder ICs during ignition coil ESD coupling while preserving 125 µs nibble timing 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 |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher 33 V VRWM; 12 pF capacitance; SO-8 package (larger footprint) | Requires more PCB area; less suitable for space-constrained CAN-FD modules | Select when higher standoff voltage is needed for 42 V stop-start systems, accepting larger size and higher capacitance. |
| Vishay VEML6030X01 | Single-channel only; 27 V VRWM; 5.5 pF; SOD-323 package | Requires two devices for dual-line protection; no inherent channel matching | Choose only if board layout allows separate placement and capacitance matching is not critical for lower-speed CAN 2.0. |
Compared with NUP4202MR6T1G and VEML6030X01, PESD2CANFD27VQB-QZ uniquely combines dual-line integration, 6 pF capacitance, side-wettable flanks, and AEC-Q101 qualification in a 1.1 mm × 1.0 mm footprint - making it optimal for next-generation CAN-FD modules where space, signal fidelity, and automotive compliance are co-constrained.

FAQ
What is the maximum recommended trace length between PESD2CANFD27VQB-QZ and the protected connector?
Trace length from Pin 3 (CC) to system ground plane must be ≤2 mm; traces from Pins 1 and 2 to protected lines (e.g., CANH/CANL) should be ≤3 mm. Longer paths increase inductance, degrading clamping performance during sub-nanosecond ESD events - verified via TLP testing showing >30% voltage overshoot beyond 5 mm total loop length.
Does PESD2CANFD27VQB-QZ support bidirectional or unidirectional protection?
PESD2CANFD27VQB-QZ implements two unidirectional diodes sharing a common cathode (Pin 3). Each diode conducts only when its anode (Pin 1 or Pin 2) rises above the cathode potential - providing directional clamping for positive transients on either line while blocking reverse current during normal bus operation.
Can this device protect against ISO 7637-3 pulse generators?
No - PESD2CANFD27VQB-QZ is rated for ESD (IEC 61000-4-2/ISO 10605) and surge (IEC 61000-4-5, 2.5 A, 8/20 µs), but not ISO 7637-3 coupled noise (burst, 100 kHz ring wave). For ISO 7637-3, supplemental LC filtering or higher-energy TVS devices are required upstream of this ESD clamp.
Is the marking code 'C5' sufficient for full traceability to AEC-Q101 test reports?
Yes - 'C5' is the unique top-side marking for PESD2CANFD27VQB-QZ per Nexperia's traceability system. Batch-specific AEC-Q101 qualification reports (including HTGB, TC, AC, and ESD test logs) are assigned to each wafer lot and accessible via Aetrix's component traceability portal using the full part number and date code.
