Product details
Overview
PESD2CANFD27UU-QX from Nexperia is a dual-line automotive CAN bus ESD protection diode in SOT23 package, rated for 24 V reverse standoff voltage, 25–30 pF capacitance, and clamping at 41 V under 5 A surge (8/20 µs). It delivers 230 W peak pulse power per line and meets IEC 61000-4-2 Level 4 (±30 kV contact ESD) and AEC-Q101 qualification for under-hood CAN FD interfaces.
For engineers reviewing the PESD2CANFD27UU-QX datasheet, PESD2CANFD27UU-QX pinout, PESD2CANFD27UU-QX application, or PESD2CANFD27UU-QX equivalent, this device supports high-speed CAN FD transceivers requiring low-capacitance, ultra-low leakage (<1 nA), and robust surge immunity in space-constrained automotive PCB layouts.
Technical Context
This bidirectional ESD protection array integrates two identical TVS diodes sharing a common cathode (Pin 3), enabling symmetrical clamping on CANH and CANL lines without polarity sensitivity. Its differential resistance of ≤300 Ω ensures fast transient response and minimal voltage overshoot during ESD events.
The device operates across −55 °C to +150 °C ambient, with junction temperature limited to 150 °C, and maintains stable clamping performance up to 150 °C - critical for engine control unit (ECU) and ADAS domain controller deployments where thermal derating must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN FD bus operation (dominant recessive levels up to ±12 V differential) |
| Clamping Voltage | 41 V at 5 A (8/20 µs) - Limits transient overvoltage to safe levels for ISO 11898-2/-5 compliant transceivers |
| Diode Capacitance | 25–30 pF at 1 MHz, 0 V - Preserves signal integrity for CAN FD data rates up to 5 Mbps with <0.5 UI jitter impact |
| ESD Withstand | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - Survives repeated ESD events in assembly, service, and field environments |
| Peak Pulse Power | 230 W per line (8/20 µs) - Handles automotive load-dump and coupled surge transients without degradation |
| Leakage Current | <1 nA at 24 V - Prevents bus bias shift and minimizes quiescent current draw in always-on gateway modules |
| AEC-Q101 Qualified | Qualified for automotive discrete semiconductors - Validated for temperature cycling, HTRB, and ESD stress per AEC standard |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 1.9 mm × 1.3 mm footprint, 1.1 mm height, gull-wing leads, JEDEC-compliant solder land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Line 1) | Connects to CANH for bidirectional clamping; forms low-impedance path to common cathode during positive/negative transients |
| 2 | Cathode (Line 2) | Connects to CANL; enables independent but coordinated protection of both differential bus lines |
| 3 | Common Cathode | Shared return node tied to chassis or local ground plane - defines reference for symmetrical clamping action |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables single-device protection of full-duplex CAN FD differential pair without polarity constraints or external biasing |
| Ultra-Low Capacitance | 25–30 pF ensures <1% signal rise-time degradation at 5 Mbps, preserving bit timing margins in high-speed CAN FD networks |
| Low-Leakage Architecture | <1 nA IR at VRWM eliminates bus pull-down risk and supports low-power sleep modes in battery-sensitive ECUs |
| Automotive Thermal Robustness | Rated for 150 °C junction temperature and qualified per AEC-Q101 - suitable for under-hood placement near powertrain modules |
| IEC 61000-4-5 Surge Compliance | Withstands 5 A (8/20 µs) surge per line - meets ISO 7637-3 and SAE J1113-11 requirements for conducted transients |
Applications
| Automotive CAN FD Gateway | ADAS Domain Controller Interface |
|---|---|
|
Use Scenario: High-bandwidth communication between radar, camera, and central compute units via CAN FD backbone. IC Role / Device Role / Timing Role: Dual-line transient suppressor placed directly at connector entry point before CAN FD transceiver input pins. Use Value: Maintains 5 Mbps signal fidelity while suppressing ±30 kV ESD strikes - prevents transceiver latch-up and firmware resets during vehicle service. |

IC Role / Device Role / Timing Role: Dual-line clamp integrated into compact BCM PCB with shared ground return to minimize loop area. Use Value: Delivers <1 nA leakage to extend battery standby life beyond 10 years - critical for key-off monitoring functions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive CAN bus ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1M2 | Lower clamping (36 V @ 5 A), higher capacitance (55 pF), same SOT23-3 package | Better suited for legacy CAN 2.0 (1 Mbps) where bandwidth margin is less critical | Select when lower clamping voltage is prioritized over high-speed signal integrity |
| TPD2E001DRYR | Single-channel (not dual), 0.5-pF capacitance, 12-V standoff, not AEC-Q101 qualified | Limited to non-automotive, low-voltage USB/IO protection; requires two devices for CAN pair | Only viable for cost-sensitive industrial prototypes lacking automotive qualification requirements |
Compared with ESDALC6V1-1M2 and TPD2E001DRYR, PESD2CANFD27UU-QX uniquely balances 24 V standoff, 25–30 pF capacitance, and AEC-Q101 compliance - making it the only drop-in solution for production CAN FD nodes demanding simultaneous speed, ruggedness, and automotive certification.

FAQ
Is PESD2CANFD27UU-QX compatible with both high-speed and fault-tolerant CAN physical layers?
Yes - its bidirectional clamping architecture and 24 V standoff voltage support both ISO 11898-2 (high-speed CAN) and ISO 11898-3 (fault-tolerant CAN) topologies. The device protects CANH and CANL independently while sharing a common cathode, enabling use in either configuration without redesign.
What is the maximum recommended PCB trace length between PESD2CANFD27UU-QX and the CAN connector?
Nexperia recommends ≤5 mm from device pins to connector pads. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot above 41 V during ESD events. Layout guidelines also require direct grounding of Pin 3 to a solid ground plane with minimal via inductance.
Does PESD2CANFD27UU-QX require external series impedance for optimal CAN FD signal integrity?
No - its 25–30 pF capacitance and ≤300 Ω differential resistance are designed to operate without series resistors. Adding external impedance risks violating CAN FD's strict impedance matching (60 Ω differential) and may distort edge rates at 5 Mbps; layout optimization is preferred over component compensation.
How does thermal derating affect peak pulse power at elevated ambient temperatures?
Per Figure 4 in the datasheet, peak pulse power drops to ~80% of 230 W at 125 °C ambient and ~40% at 150 °C. This reflects junction temperature limits - designers must ensure thermal resistance from junction-to-ambient (RθJA) remains ≤100 K/W in PCB layout to sustain full rating at 85 °C ambient.
