Product details
Overview
PESD2CANFD27UQC-QZ from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1412D-3 (SOT8009) package, designed for CAN-FD and CAN bus lines with 27 V reverse standoff voltage, 34 V clamping at 1 A, and 4.0 pF capacitance. It provides IEC 61000-4-2 ±15 kV and ISO 10605 ±15 kV (150 pF/330 Ω) ESD immunity in vehicle network interfaces.
For engineers reviewing the PESD2CANFD27UQC-QZ datasheet, PESD2CANFD27UQC-QZ pinout, PESD2CANFD27UQC-QZ application, or PESD2CANFD27UQC-QZ equivalent, this device supports high-speed automotive serial buses requiring low-capacitance, AEC-Q101-qualified transient suppression with side-wettable flanks for automated optical inspection (AOI) and solder joint reliability.
Technical Context
This bidirectional dual-cathode TVS array uses common-cathode architecture (Pin 3 = CC) to protect two independent signal lines-K1 (Pin 1) and K2 (Pin 2)-against ESD and surge transients. Its low dynamic resistance (1.3 Ω) and fast response enable effective clamping of 8/20 µs surges up to 1.8 A peak pulse current.
The device operates across –55 °C to +150 °C ambient, with junction temperature rated to 150 °C and storage range from –65 °C to +150 °C. Capacitance matching between channels is ≤0.5%, ensuring balanced signal integrity on differential or parallel bus lines like CAN-FD.
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, 3.3 V supply rails). |
| Clamping Voltage | 34 V (typ.) at 1 A - Limits transient voltage to safe levels below CAN transceiver absolute maximum ratings (typically 40 V). |
| Diode Capacitance | 4.0 pF (typ.) - Minimizes signal distortion and timing skew on high-speed CAN-FD (up to 5 Mbps) and SENT lines. |
| ESD Rating | ±15 kV IEC 61000-4-2 contact - Meets automotive OEM requirements for connector-level ESD robustness. |
| Peak Pulse Current | 1.8 A (8/20 µs) - Handles IEC 61000-4-5 surge events without degradation in AEC-Q101-compliant systems. |
| Leakage Current | 1 nA (typ.) at 27 V - Prevents DC loading on bias-sensitive bus receivers and reduces power loss in always-on modules. |
| AEC-Q101 Qualified | Yes - Validated for automotive under-hood and cabin applications per stress test standard for discrete semiconductors. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-small surface-mount package measuring 1.4 mm × 1.2 mm × 0.48 mm with 0.8 mm pitch and side-wettable flanks for solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Protected node for first bus line (e.g., CANH); connects to anode of internal diode 1, cathode tied to common terminal. |
| 2 | K2 (Cathode 2) | Protected node for second bus line (e.g., CANL); anode of internal diode 2, cathode tied to common terminal. |
| 3 | CC (Common Cathode) | Shared cathode connection to system ground or low-impedance return path; enables compact dual-line protection layout. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 4.0 pF ensures minimal signal rise-time degradation on 5 Mbps CAN-FD and 1 Mbps FlexRay buses. |
| Dual-channel common-cathode topology | Reduces PCB footprint by 40% vs. two discrete diodes and eliminates inter-channel mismatch in clamping behavior. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-side terminals, improving manufacturing yield. |
| Low dynamic resistance | 1.3 Ω minimizes voltage overshoot during fast ESD events (<1 ns rise time), enhancing protection margin. |
Applications
| Automotive CAN-FD Interface | Automotive CAN Bus |
|---|---|
|
Use Scenario: High-speed body control module communicating over 2–5 Mbps CAN-FD with ECU gateway. IC Role / Device Role / Timing Role: ESD clamp placed directly at OBD-II connector or CAN transceiver I/O pins to suppress ±15 kV contact discharge. Use Value: Prevents latch-up or permanent damage to CAN FD transceivers (e.g., TJA1057x) while maintaining signal integrity via 4.0 pF loading. |
Use Scenario: Powertrain sensor cluster using legacy 1 Mbps CAN connecting to engine control unit. IC Role / Device Role / Timing Role: Dual-line protection at CANH/CANL inputs of isolated CAN transceiver (e.g., ISO1050) in harsh under-hood environment. Use Value: Delivers AEC-Q101 compliance and 1.8 A surge handling without compromising common-mode rejection or bus termination stability. |
| Automotive FlexRay Network | Automotive SENT Sensor Interface |
|
Use Scenario: Active suspension controller using FlexRay for deterministic 10 Mbps time-triggered communication. IC Role / Device Role / Timing Role: Transient suppression on FlexRay A/B differential pairs upstream of physical layer transceiver (e.g., TJA1080A). Use Value: 4.0 pF capacitance avoids signal edge rounding that would violate FlexRay's <1 ns jitter budget and bit-timing tolerance. |
Use Scenario: Engine knock sensor transmitting analog pressure data via single-wire SENT protocol (SAE J2716). IC Role / Device Role / Timing Role: ESD guard on SENT output line before connector, protecting microcontroller GPIO and external pull-up resistor. Use Value: Sub-1 nA leakage preserves SENT's precise pulse-width modulation accuracy; 27 V VRWM avoids interference with 5 V or 12 V supply domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUF2221MUTAG | Higher capacitance (12 pF), lower VRWM (15 V), same SOT-723 package but no side-wettable flanks. | Not suitable for CAN-FD > 2 Mbps due to bandwidth limitation; limited to 125 °C Tj max. | Select only for cost-sensitive 125 °C non-under-hood CAN nodes where AOI is not required. |
| Vishay VEML6030X01 | Single-channel, 27 V VRWM, 35 V VCL, 2.5 pF, but lacks dual-line integration and AEC-Q101 qualification. | Requires two devices and extra routing; no common-cathode advantage for space-constrained modules. | Use only when channel isolation is mandatory and board area permits discrete placement. |
Compared with NUF2221MUTAG and VEML6030X01, PESD2CANFD27UQC-QZ uniquely combines CAN-FD-ready 4.0 pF capacitance, AEC-Q101 qualification, side-wettable flanks, and integrated dual-channel common-cathode topology-enabling smaller footprint, higher reliability, and production-ready manufacturability in automotive ECUs.

FAQ
What is the maximum operating temperature for PESD2CANFD27UQC-QZ?
The device supports ambient temperatures from –55 °C to +150 °C and junction temperatures up to 150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. This enables use in under-hood modules such as transmission control units and battery management systems where sustained 125 °C ambient is typical.
Can PESD2CANFD27UQC-QZ be used for USB or HDMI protection?
No-its 27 V reverse standoff voltage and 4.0 pF capacitance are optimized for automotive bus voltages (e.g., CAN ±2.5 V, FlexRay ±2.5 V) and not compatible with 3.3 V or 5 V digital interfaces. USB/HDMI require lower VRWM (e.g., 5.5 V) and tighter capacitance control (<1.5 pF), making this part unsuitable for those applications.
Does PESD2CANFD27UQC-QZ require external biasing or series resistors?
No external biasing is needed-the device operates passively as a clamping diode. Series resistors are not required for ESD protection but may be added for EFT filtering if system-level testing reveals susceptibility beyond IEC 61000-4-4 Level 4. Layout best practices (short traces, ground proximity) supersede passive component additions.
How does the common cathode (Pin 3) connection affect grounding strategy?
Pin 3 must connect to a low-inductance, low-impedance ground plane-ideally via multiple vias-to ensure symmetric clamping and minimize ground bounce during ESD events. Sharing Pin 3 with noisy digital ground or high-current return paths degrades clamping performance and risks coupling transients into protected signals.
