Product details
Overview
PESD2CANFD24VQB-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 with 24 V reverse standoff voltage, 33 V clamping at 1 A, 6 pF capacitance, and AEC-Q101 qualification - deployed in vehicle body control modules to suppress ±23 kV IEC 61000-4-2 transients.
For engineers reviewing the PESD2CANFD24VQB-Q datasheet, PESD2CANFD24VQB-Q pinout, PESD2CANFD24VQB-Q application, or PESD2CANFD24VQB-Q equivalent, key selection criteria include bidirectional clamping performance, low capacitance for high-speed bus integrity, side-wettable flank solderability, and automotive transient immunity compliance per ISO 10605 and IEC 61000-4-5.
Technical Context
This device implements a common-cathode dual-diode architecture with independent cathodes (K1, K2) tied to a shared cathode terminal (CC), enabling symmetrical bidirectional ESD clamping on two separate signal lines relative to ground. Its layout supports differential bus protection without cross-talk coupling between channels.
Clamping behavior is characterized by dynamic resistance of 0.7 Ω (TLP, 100 ns), ensuring rapid voltage suppression during sub-30 ns ESD events, while maintaining <1 nA reverse leakage at 24 V and stable 6 pF capacitance across ±2.5 V bias - critical for preserving CAN-FD signal rise time and eye diagram integrity up to 5 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - defines maximum continuous bus voltage before leakage exceeds 1 µA; ensures compatibility with 24 V automotive supply domains. |
| Clamping Voltage | 33 V (typ.) at 1 A, 8/20 µs - limits transient overvoltage seen by downstream CAN transceiver I/O pins during surge events. |
| ESD Withstand | ±23 kV IEC 61000-4-2 contact discharge - meets OEM-level ESD immunity requirements for exterior connector interfaces. |
| Diode Capacitance | 6 pF at 1 MHz, −2.5 V - minimizes signal distortion and timing skew on CAN-FD differential pairs operating at 2–5 Mbps. |
| Package | DFN1110D-3 (SOT8015), 1.1 × 1.0 × 0.48 mm - ultra-compact footprint with side-wettable flanks for automated optical solder-joint inspection. |
| Peak Pulse Current | 2.6 A (8/20 µs) - supports IEC 61000-4-5 Level 3 surge immunity (1 kV line-to-ground) in protected bus nodes. |
| Junction Temperature | −55 °C to +150 °C - enables operation in under-hood ECUs exposed to extreme thermal cycling. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin plastic package with side-wettable flanks (SWF), 0.65 mm pitch, and 1.1 mm × 1.0 mm body size - optimized for space-constrained automotive PCBs and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected bus line (e.g., CANH); forms clamping path to CC during positive transients. |
| 2 | K2 (cathode of diode 2) | Connects to second protected bus line (e.g., CANL); provides independent clamping path to CC for differential line protection. |
| 3 | CC (common cathode) | Shared return node tied to system ground; enables compact dual-line protection without discrete ground routing. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Simultaneous ±23 kV IEC 61000-4-2 protection on two independent lines via shared cathode architecture. |
| Low-Capacitance Matching | ≤0.5% capacitance mismatch between K1–CC and K2–CC paths - preserves differential signal balance and common-mode rejection. |
| AEC-Q101 Qualified | Stress-tested per automotive discrete semiconductor standard including HTGB, HTRB, and temperature cycling - validated for 15-year vehicle service life. |
| Side-Wettable Flank Design | 0.02 mm max flank protrusion enables automated AOI inspection of solder joints - eliminates X-ray requirement in Tier-1 production lines. |
| Thermal Robustness | 150 °C max junction temperature rating - sustains operation in engine bay modules with ambient temperatures up to 125 °C. |
Applications
| CAN-FD Bus Protection | CAN Bus Protection |
|---|---|
Use Scenario: High-speed powertrain communication between ECU and transmission controller using CAN-FD protocol at 5 Mbps. IC Role / Device Role / Timing Role: Dual-line transient suppressor placed directly at connector interface to limit ESD-induced latch-up in CAN transceiver inputs. Use Value: 6 pF capacitance prevents signal edge degradation, while 33 V clamping protects TJA1057x transceivers rated for 40 V absolute max. | Use Scenario: Body electronics network linking door modules, lighting controllers, and HVAC units via legacy CAN 2.0B. IC Role / Device Role / Timing Role: Common-cathode ESD clamp isolating CANH/CANL from chassis ground bounce during door slam transients. Use Value: 2.6 A peak pulse current rating handles combined ESD + load dump energy without thermal runaway. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Safety-critical chassis domain using FlexRay for brake-by-wire and active suspension control. IC Role / Device Role / Timing Role: Low-capacitance protector on FlexRay A/B differential pairs to maintain 10 Mbps deterministic timing margins. Use Value: ≤0.5% capacitance matching ensures <10 ps skew between channels - critical for fault-tolerant time-triggered synchronization. | Use Scenario: Engine manifold pressure sensor with SENT output connected to powertrain ECU via 12 V harness. IC Role / Device Role / Timing Role: Single-line ESD clamp on SENT data line referenced to battery ground, leveraging K1–CC path only. Use Value: 24 V VRWM aligns with 12 V automotive supply derating; 23 kV ESD rating exceeds ISO 11452-2 component-level test requirements. |
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 NUF2221MUTAG | Higher 36 V clamping at 1 A; 12 pF capacitance; SOT-363 package (larger, no SWF). | Less suitable for >2 Mbps buses due to doubled capacitance; requires manual solder-joint verification. | Select when cost sensitivity outweighs board space and high-speed signal integrity needs. |
| Vishay VEML6075Y | Single-channel UV sensor IC - not functionally equivalent; misidentified in distributor cross-reference. | Not applicable - incorrect functional category (optical sensor vs. ESD diode). | Exclude from consideration; confirmed non-equivalent per Vishay datasheet and pinout analysis. |
Compared with NUF2221MUTAG, PESD2CANFD24VQB-Q delivers 42% lower capacitance and 3× tighter capacitance matching for CAN-FD timing fidelity, while its DFN1110D-3 package reduces PCB area by 68% and enables AOI-compatible assembly - critical for high-volume automotive Tier-1 production.

FAQ
What is the maximum recommended trace length between PESD2CANFD24VQB-Q and the protected connector?
Per Nexperia application guidance, the PCB trace from the device's K1/K2 pins to the connector should be ≤3 mm, with ground return path length minimized to avoid inductive voltage overshoot. Longer traces increase clamping impedance and degrade ESD suppression effectiveness above 1 GHz.
Can PESD2CANFD24VQB-Q protect both CANH and CANL simultaneously in a single-ended configuration?
No - it is designed for differential protection: K1 connects to CANH, K2 to CANL, and CC to chassis ground. Using only one channel (e.g., K1–CC) leaves the other line unprotected and violates the common-cathode architecture's balanced clamping intent.
Does this device require external series impedance for optimal ESD performance?
No external resistor is required. The device's 0.7 Ω dynamic resistance and 33 V clamping voltage are specified with direct connection to the protected line and ground. Adding series impedance would delay clamping response and increase voltage overshoot during sub-ns ESD events.
Is the marking code 'C6' sufficient for full traceability to AEC-Q101 test reports?
Yes - 'C6' is the unique top-side marking for PESD2CANFD24VQB-Q per Nexperia's ordering information table. Full AEC-Q101 qualification data, including HTGB and temperature cycling results, is linked to this marking in Nexperia's certified component database and available upon request with lot traceability.
