Product details
Overview
PESD2CANFD24V-QB from Nexperia is a dual-channel automotive-grade ESD protection diode in DFN1110D-3 (SOT8015) package, designed to safeguard CAN-FD and CAN bus lines against IEC 61000-4-2 ±23 kV contact discharge, with 24 V reverse standoff voltage, 33 V clamping at 1 A, and 6 pF typical capacitance per channel.
For engineers reviewing the PESD2CANFD24V-QB datasheet, PESD2CANFD24V-QB pinout, PESD2CANFD24V-QB application, or PESD2CANFD24V-QB equivalent, this device supports high-speed in-vehicle network protection where low capacitance, AEC-Q101 qualification, and side-wettable flank solderability are critical for automotive PCB layout and reliability.
Technical Context
This bidirectional ESD protection array integrates two independent TVS diodes sharing a common cathode (Pin 3), enabling symmetrical transient suppression on differential bus lines like CANH/CANL. Its architecture delivers matched diode capacitance (±0.5% ΔCd/Cd) and low dynamic resistance (0.7 Ω) for consistent clamping under fast-rising ESD pulses.
It operates within −55 °C to +150 °C ambient range and supports peak pulse currents up to 2.6 A (8/20 µs), with clamping validated per IEC 61000-4-5 and ISO 10605 (150 pF/330 Ω). The device is qualified to AEC-Q101 and rated for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN-FD bus operation (±12 V common-mode range). |
| Clamping Voltage | 33 V (typ.) at 1 A - Limits transient voltage to safe levels below CAN transceiver absolute maximum ratings. |
| ESD Rating | ±23 kV IEC 61000-4-2 - Meets stringent automotive ESD immunity requirements without degradation. |
| Diode Capacitance | 6 pF (typ.) - Minimizes signal distortion on high-speed CAN-FD (up to 5 Mbps) and FlexRay buses. |
| Peak Pulse Current | 2.6 A (8/20 µs) - Handles surge energy from coupled transients while maintaining low clamping. |
| Dynamic Resistance | 0.7 Ω - Reduces voltage overshoot during fast ESD events by limiting IR drop across the protection path. |
| Junction Temperature | 150 °C max - Supports placement near heat-generating components in engine control units and ADAS modules. |
Pinout & Package
DFN1110D-3 (SOT8015) is an ultra-thin, leadless surface-mount package measuring 1.1 mm × 1.0 mm × 0.48 mm with side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to protected line 1 (e.g., CANH); forms one leg of bidirectional ESD clamp to common cathode. |
| 2 | K2 (Cathode 2) | Connects to protected line 2 (e.g., CANL); second independent clamp path sharing Pin 3 return. |
| 3 | CC (Common Cathode) | Ground reference node for both diodes; must connect directly to low-inductance chassis or system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| Side-wettable flanks (SWF) | Enables reliable AOI and X-ray inspection of solder fillets on ultra-compact 0.65 mm pitch terminals. |
| Matched capacitance (ΔCd/Cd ≤ 0.5%) | Maintains differential signal integrity by minimizing skew between CANH and CANL protection paths. |
| Low clamping with low Rdyn | 0.7 Ω dynamic resistance ensures <33 V clamping at 1 A, protecting transceivers with 36 V abs max ratings. |
| Ultra-low 6 pF capacitance | Preserves signal rise/fall times on 5 Mbps CAN-FD buses without requiring trace length compensation. |
Applications
| Automotive CAN-FD Bus Protection | Automotive CAN Bus Protection |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface in vehicle telematics control units. IC Role / Device Role / Timing Role: Dual-channel transient voltage suppressor placed before CAN-FD transceiver input pins. Use Value: Prevents latch-up or permanent damage to transceivers during service technician hot-plug events (IEC 61000-4-2 ±23 kV). |
Use Scenario: Front-end protection for body control module (BCM) CAN nodes exposed to door harnesses. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on differential CANH/CANL lines. Use Value: Maintains signal integrity at 1 Mbps while suppressing EFT bursts and load dump-induced surges. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Transient suppression on FlexRay A/B channels in powertrain domain controllers. IC Role / Device Role / Timing Role: Matched dual-diode array ensuring balanced clamping on high-speed deterministic bus lines. Use Value: 6 pF capacitance avoids timing jitter on 10 Mbps FlexRay signals; ±23 kV rating covers manufacturing ESD handling. |
Use Scenario: ESD hardening of single-wire SENT output from pressure or temperature sensors. IC Role / Device Role / Timing Role: Single-channel usage (K1–CC or K2–CC) for unidirectional sensor line protection. Use Value: 24 V VRWM aligns with SENT supply rails; low leakage (<50 nA) prevents sensor bias current interference. |
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 12 pF capacitance; 22 V VRWM; not AEC-Q101 qualified. | Suitable for non-automotive industrial CAN but lacks automotive reliability validation. | Select only for cost-sensitive non-automotive designs where 12 pF capacitance is acceptable. |
| Vishay VEML6030X01 | Single-channel photodiode with integrated ESD protection; not a discrete TVS array. | Designed for ambient light sensing, not bus line protection. | Not functionally comparable; excluded from bus protection use cases. |
Compared with NUF2221MUTAG and VEML6030X01, PESD2CANFD24V-QB uniquely combines AEC-Q101 qualification, 6 pF capacitance, and dual-channel matched topology-making it the only validated solution for CAN-FD and FlexRay in production automotive ECUs.

FAQ
What is the maximum operating temperature for PESD2CANFD24V-QB?
The device supports continuous operation from −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. This enables deployment in under-hood ECUs, battery management systems, and ADAS radar modules where thermal margins are constrained.
Can PESD2CANFD24V-QB be used for single-line protection?
Yes - either channel (Pin 1–Pin 3 or Pin 2–Pin 3) can be used independently for unidirectional protection of SENT, LIN, or other single-ended automotive signals, retaining its 24 V VRWM, 33 V clamping, and 6 pF capacitance specifications.
Is the DFN1110D-3 package compatible with standard reflow profiles?
Yes - the SOT8015 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 30 s max). Stencil thickness of 0.1 mm is recommended for optimal solder paste release.
How does the common cathode configuration affect PCB layout?
The shared cathode (Pin 3) requires a low-inductance, direct connection to a solid ground plane - not daisy-chained ground traces. Layout best practice places the device adjacent to the connector, with symmetric trace lengths from Pins 1 and 2 to their respective bus lines and minimal loop area to Pin 3.
