Product details
Overview
PESD2CANFD27VU-QX from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed specifically for CAN FD bus lines. It provides 24 V reverse standoff voltage, 25–30 pF capacitance per diode, 41 V clamping at 5 A surge, <1 nA leakage, and 30 kV IEC 61000-4-2 contact ESD protection - enabling robust transient suppression in high-speed vehicle communication interfaces.
For engineers reviewing the PESD2CANFD27VU-QX datasheet, PESD2CANFD27VU-QX pinout, PESD2CANFD27VU-QX application, or PESD2CANFD27VU-QX equivalent, this device is selected for CAN FD physical layer protection where low capacitance, AEC-Q101 qualification, and sub-41 V clamping under 5 A 8/20 µs surge are mandatory design requirements.
Technical Context
This dual-cathode bidirectional TVS diode integrates two independent ESD protection paths (Pin 1→3 and Pin 2→3) sharing a common cathode (Pin 3), forming a symmetric clamp topology ideal for differential CAN FD bus pairs. Its 25–30 pF capacitance at 1 MHz and 0 V bias ensures minimal signal integrity impact on >5 Mbps CAN FD data rates.
The device operates within −55 °C to +150 °C ambient range and achieves 230 W peak pulse power per channel under IEC 61000-4-5 8/20 µs surge, with clamping voltage tightly specified at 34 V (IPP = 1 A) and 41 V (IPP = 5 A), enabling predictable overvoltage limiting during transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - defines maximum continuous bus voltage before leakage rises; matches CAN FD nominal 12 V supply with 2× safety margin |
| Clamping Voltage (IPP = 5 A) | 41 V - limits transient voltage seen by CAN transceiver during 8/20 µs surge, staying below typical 42 V absolute max rating |
| Diode Capacitance | 25–30 pF - low enough to avoid signal rise/fall time degradation on CAN FD buses operating up to 5 Mbps |
| ESD Withstand (IEC 61000-4-2) | 30 kV contact - exceeds automotive OEM requirements for dashboard, gateway, and ADAS module ESD immunity |
| Peak Pulse Power | 230 W per diode - sustains 5 A / 8/20 µs surge without thermal runaway, validated per IEC 61000-4-5 |
| Leakage Current | <1 nA at 24 V - prevents measurable DC loading on bias networks or termination resistors in CAN FD receivers |
| AEC-Q101 Qualified | Yes - certified for automotive under stress test conditions including temperature cycling, HTRB, and ESD, enabling use in engine bay and chassis modules |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package, 3-pin, 2.8 mm × 1.4 mm footprint, 1.1 mm height, with gull-wing leads optimized for reflow soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Connects to CANH line; forms first ESD path to common cathode (Pin 3) during positive transients |
| 2 | Cathode 2 | Connects to CANL line; forms second ESD path to common cathode (Pin 3) during positive transients |
| 3 | Common Cathode | Shared return node tied to system ground; completes both clamping paths for bidirectional transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel CAN FD protection | Single SOT23 device protects both CANH and CANL lines simultaneously without external components or layout duplication |
| Low 25–30 pF capacitance | Maintains signal integrity on high-speed CAN FD buses (up to 5 Mbps) without edge rounding or timing jitter |
| 41 V clamping at 5 A | Ensures protected CAN transceiver remains within safe operating area during ISO 7637-3 pulse 5a/b surges |
| AEC-Q101 qualification | Validated for automotive under temperature cycling, high-temp reverse bias, and ESD stress - supports PPAP documentation |
| <1 nA leakage at 24 V | Eliminates DC current draw that could shift common-mode voltage or interfere with split-termination bias networks |
Applications
| Automotive Gateway Module | ADAS Camera ECU |
|---|---|
|
Use Scenario: High-speed CAN FD backbone connecting domain controllers, requiring ESD resilience against assembly-line handling and field electrostatic events. IC Role / Device Role / Timing Role: Dual-line transient suppressor placed directly at connector interface, clamping fast-rising ESD pulses before they reach the CAN FD transceiver. Use Value: Prevents latch-up or permanent damage to transceivers during 30 kV contact discharge, maintaining communication uptime across vehicle software updates and diagnostics. |
Use Scenario: Front-facing camera ECU exposed to humidity, vibration, and frequent disconnection in service bays, needing reliable bus-level ESD hardening. IC Role / Device Role / Timing Role: Low-capacitance protector on CAN FD link between camera and central ADAS processor, preserving signal fidelity at 2+ Mbps. Use Value: Enables compliance with OEM-specific ESD test plans (e.g., GMW3172, Ford ES-XW7T-1A278-AC) without sacrificing data rate or adding board space. |
| Electric Powertrain Inverter | Body Control Module (BCM) |
|
Use Scenario: CAN FD network inside high-voltage inverter housing, subject to conducted surges from IGBT switching and grounding transients. IC Role / Device Role / Timing Role: Surge-rated protector co-located with CAN connector, absorbing 230 W 8/20 µs pulses induced by nearby power electronics noise. Use Value: Avoids false error frames or bus-off states caused by transient-induced bit errors, supporting ASIL-B functional safety requirements. |
Use Scenario: Central BCM managing door locks, lighting, and HVAC via CAN FD, installed in cabin environments with high human interaction and static buildup. IC Role / Device Role / Timing Role: AEC-Q101-qualified ESD guard on each CAN FD port, ensuring long-term reliability across 15+ year vehicle lifecycles. Use Value: Reduces field returns due to intermittent CAN communication loss after ESD events, lowering warranty cost and improving brand trust. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN FD ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1M2 | Lower 6.1 V standoff, higher 120 pF capacitance, unidirectional configuration | Requires external series resistors for CAN FD; unsuitable for direct placement on high-speed differential lines | Select only if protecting low-speed CAN or LIN lines where capacitance tolerance is relaxed |
| TPD2E001DRYR | 2-channel, 5.5 V standoff, 12 pF capacitance, non-AEC-Q101 rated | Lacks automotive qualification; not validated for temperature cycling or long-term reliability in under-hood environments | Acceptable for consumer or industrial CAN FD prototypes but not for production automotive ECUs |
Compared with PESD2CANFD27VU-QX, ESDALC6V1-1M2 trades off CAN FD compatibility for lower voltage protection, while TPD2E001DRYR sacrifices automotive qualification for ultra-low capacitance - making the Nexperia device the only option meeting full CAN FD + AEC-Q101 + ≤30 pF requirements.

FAQ
What is the maximum operating temperature for PESD2CANFD27VU-QX?
The device supports junction temperatures up to 150 °C and ambient operation from −55 °C to +150 °C, verified per AEC-Q101 thermal cycling and high-temperature reverse bias tests - enabling placement near power stages or in engine compartment modules without derating.
Does PESD2CANFD27VU-QX support bidirectional ESD protection?
Yes - its dual-cathode architecture with shared Pin 3 enables symmetrical clamping for both positive and negative ESD transients on CANH and CANL lines, meeting IEC 61000-4-2 level 4 (±8 kV contact, ±15 kV air) without polarity constraints.
How does the 25–30 pF capacitance affect CAN FD signal integrity?
At 1 MHz and 0 V bias, this capacitance introduces negligible loading on CAN FD differential pairs: measured eye diagrams show <1% rise-time degradation at 5 Mbps, and no measurable jitter increase - confirmed in Nexperia's application note AN11169 for high-speed bus protection.
Is PESD2CANFD27VU-QX compatible with standard SOT23 reflow profiles?
Yes - the SOT23 (TO-236AB) package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for 30 seconds, matching standard lead-free assembly processes used in automotive PCB manufacturing.
