Product details
Overview
PESD2CANFD27UQB-Q 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 provides 27 V reverse standoff voltage, 34 V clamping at 1 A, 4.0 pF capacitance, 15 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification - enabling robust transient suppression in high-speed in-vehicle networks.
For engineers reviewing the PESD2CANFD27UQB-Q datasheet, PESD2CANFD27UQB-Q pinout, PESD2CANFD27UQB-Q application, or PESD2CANFD27UQB-Q equivalent, key selection criteria include bidirectional clamping performance, ultra-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 space-constrained automotive PCB layouts.
Technical Context
This device implements a dual-channel, common-cathode TVS diode architecture with two independent anode-to-cathode paths (Pin 1→3 and Pin 2→3), optimized for differential bus protection. Its low dynamic resistance (1.3 Ω) and fast response (<1 ns) ensure effective clamping of ESD transients per IEC 61000-4-2 and ISO 10605 standards without distorting CAN-FD's 5 Mbps signaling waveform.
The DFN1110D-3 package integrates side-wettable flanks for solder joint quality verification, while its 1.1 mm × 1.0 mm footprint supports placement directly at vehicle harness connectors. The 27 V VRWM aligns with CAN-FD's ±30 V common-mode range, and 4.0 pF typical capacitance minimizes insertion loss and timing skew across differential pairs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Ensures no conduction during normal CAN-FD bus operation (±25 V common-mode range) |
| Clamping Voltage | 34 V at 1 A (8/20 µs) - Limits transient voltage to safe levels below transceiver absolute maximum ratings |
| Diode Capacitance | 4.0 pF at 1 MHz, −2.5 V - Preserves signal integrity on 5 Mbps CAN-FD differential lines with <0.1 UI jitter impact |
| ESD Withstand | 15 kV contact discharge (IEC 61000-4-2) - Meets OEM-level ESD immunity requirements for body control modules |
| AEC-Q101 Qualified | Qualified per stress test standard for discrete semiconductors - Validated for under-hood temperature cycling (−55 °C to 150 °C) |
| Peak Pulse Current | 1.8 A (8/20 µs) - Handles surge events from load dump or inductive switching in 12 V automotive systems |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package measuring 1.1 mm × 1.0 mm × 0.48 mm with 0.65 mm pitch and side-wettable flanks for AOI-compatible reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode connects to CANH or first protected line; cathode ties to common return path |
| 2 | K2 (Cathode 2) | Anode connects to CANL or second protected line; enables dual-line protection with single ground reference |
| 3 | CC (Common Cathode) | Shared cathode node routed to chassis or low-impedance ground plane - critical for balanced clamping and minimal ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode topology | Enables compact, symmetric protection of differential CAN-FD pairs without separate ground traces for each diode |
| Side-wettable flanks (SWF) | Supports automated optical inspection of solder joints - essential for zero-defect automotive manufacturing compliance |
| Ultra-low 4.0 pF capacitance | Minimizes signal rise-time degradation and reflection on high-speed CAN-FD buses operating up to 5 Mbps |
| 15 kV IEC 61000-4-2 & ISO 10605 rating | Validated for both system-level and component-level ESD testing required by major Tier 1 suppliers |
| 1.3 Ω dynamic resistance | Reduces clamping voltage overshoot during fast transients, improving margin against transceiver overvoltage failure |
Applications
| CAN-FD Bus Protection | CAN Bus Protection |
|---|---|
|
Use Scenario: Protecting high-speed powertrain ECUs communicating over 2–5 Mbps CAN-FD networks in engine control units and transmission controllers. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between CAN transceiver I/O pins and vehicle harness connector. Use Value: Maintains signal fidelity at 5 Mbps while clamping 8/20 µs surges to ≤34 V - preventing transceiver latch-up or permanent damage during ESD events. |
Use Scenario: Securing legacy 1 Mbps CAN nodes in body electronics modules such as door control units and seat control modules. IC Role / Device Role / Timing Role: Dual-line ESD clamp mounted directly at PCB edge connector to minimize transient loop area. Use Value: Delivers 15 kV ESD immunity without adding series impedance or capacitance that would degrade dominant-time or recessive-time timing margins. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
|
Use Scenario: Safeguarding FlexRay communication channels in advanced driver-assistance systems (ADAS) domain controllers requiring deterministic 10 Mbps data transfer. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on differential FlexRay A/B lines, referenced to isolated ground plane. Use Value: 4.0 pF capacitance ensures <1% signal distortion on 10 Mbps FlexRay edges, preserving time-triggered protocol synchronization. |
Use Scenario: Shielding SENT (Single Edge Nibble Transmission) sensor interfaces in engine knock and pressure sensors exposed to under-hood ESD. IC Role / Device Role / Timing Role: Single-line ESD clamp on SENT data line, leveraging shared cathode for minimal board space in small-sensor PCBs. Use Value: 27 V VRWM exceeds SENT's 0–5 V logic swing and 12 V supply tolerance, avoiding leakage-induced measurement offset in analog sensor front-ends. |
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 5.5 pF capacitance; 24 V VRWM; SO-8 package (3.9 mm × 4.9 mm) | Larger footprint limits use in space-constrained CAN-FD modules; lower VRWM reduces margin on 24 V commercial vehicle buses | Select when board layout allows larger package and 24 V standoff suffices for legacy CAN systems |
| Infineon ESD224-BI02025 | 30 V VRWM; 3.5 pF capacitance; same DFN1110D-3 package; 12 kV IEC 61000-4-2 rating | Higher standoff supports 24 V truck/bus systems but reduced ESD rating may not meet OEM Tier 1 requirements for passenger vehicles | Prefer for heavy-duty vehicle platforms where 30 V operation is mandatory and 12 kV ESD is acceptable |
Compared with NUF2221MUTAG and ESD224-BI02025, PESD2CANFD27UQB-Q uniquely balances 27 V standoff, 4.0 pF capacitance, 15 kV ESD rating, and DFN1110D-3 size - making it optimal for next-generation CAN-FD ECUs requiring compact, high-fidelity, and fully qualified protection.

FAQ
What is the maximum junction temperature rating for PESD2CANFD27UQB-Q?
The device is rated for a maximum junction temperature of 150 °C, validated per AEC-Q101 thermal cycling and high-temperature operating life tests. This enables reliable operation in under-hood environments such as engine control units and transmission control modules where ambient temperatures reach 125 °C and power dissipation induces additional thermal rise.
Does PESD2CANFD27UQB-Q support bidirectional or unidirectional ESD protection?
PESD2CANFD27UQB-Q provides bidirectional protection per channel, achieved through symmetrical avalanche breakdown characteristics between anode and cathode terminals. Each channel (Pin 1–3 and Pin 2–3) clamps both positive and negative transients - essential for differential bus protocols like CAN-FD that swing above and below ground reference.
How does the common cathode (Pin 3) connection affect PCB layout?
Pin 3 must be connected to a low-inductance, dedicated ground plane with minimal trace length - ideally via multiple vias - to prevent ground bounce during simultaneous clamping events on both channels. Sharing this node with noisy digital or power grounds degrades clamping symmetry and increases residual voltage on protected lines.
Is the 4.0 pF capacitance measured differentially or single-ended?
The 4.0 pF value is measured single-ended: capacitance from Pin 1 to Pin 3 and Pin 2 to Pin 3, each at 1 MHz and −2.5 V reverse bias. Differential capacitance (Pin 1 to Pin 2) is not specified, but matching tolerance of ±0.5% ensures balanced loading on CAN-H and CAN-L lines, preserving common-mode rejection.
