Product details
Overview
PESD2CANFD24V-TR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed for bidirectional transient suppression on CAN-FD and CAN bus lines. It delivers 24 V reverse standoff voltage, 33 V clamping at 1 A (8/20 µs), 6 pF capacitance, 23 kV IEC 61000-4-2 ESD rating, and AEC-Q101 qualification for under-hood vehicle networks.
For engineers reviewing the PESD2CANFD24V-TR datasheet, PESD2CANFD24V-TR pinout, PESD2CANFD24V-TR application, or PESD2CANFD24V-TR equivalent, this device is selected for high-speed, low-capacitance ESD protection where junction temperature up to 175 °C, common-cathode dual-diode topology, and ISO 10605 compliance are required in automotive serial bus interfaces.
Technical Context
This device implements a dual unidirectional TVS diode configuration with shared cathode (pin 3), enabling independent protection of two differential bus lines (e.g., CANH and CANL) while minimizing PCB footprint. Its 6 pF typical capacitance ensures minimal signal integrity impact on CAN-FD data rates up to 5 Mbps.
The 24 V VRWM supports 24 V automotive supply rails and provides margin above nominal CAN bus common-mode voltage (±12 V). Clamping at 33 V (1 A, 8/20 µs) limits transients below IC-level damage thresholds, and dynamic resistance of 0.7 Ω enables fast energy dissipation during ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Blocks normal CAN-FD bus operation up to ±24 V without leakage, preserving signal integrity during steady-state. |
| Clamping Voltage | 33 V at 1 A (8/20 µs) - Limits transient voltage seen by downstream CAN transceiver to safe levels during surge events. |
| ESD Rating | 23 kV contact discharge (IEC 61000-4-2) - Meets stringent automotive ESD immunity requirements for exposed connectors. |
| Diode Capacitance | 6 pF at 1 MHz, VR = −2.5 V - Low enough to avoid signal rise-time degradation on 5 Mbps CAN-FD buses. |
| Junction Temperature | 175 °C max - Enables placement near hot engine-control units without derating or thermal shutdown. |
| AEC-Q101 Qualified | Qualified per Stress Test Qualification for Discrete Semiconductors - Validated for automotive under-hood reliability and lifetime. |
Pinout & Package
Package: SOT23 (TO-236AB), 3-terminal surface-mount plastic package, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms unidirectional clamp to common cathode. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); enables independent, matched protection path. |
| 3 | CC (Common Cathode) | Shared return path to ground or low-impedance reference; minimizes layout asymmetry and ensures balanced clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line ESD protection | Single SOT23 package protects both CANH and CANL with matched 6 pF capacitance and <0.5% ΔCd/Cd tolerance. |
| Automotive thermal robustness | Rated for continuous operation at Tj = 175 °C - supports placement in high-temperature zones without derating. |
| Low dynamic resistance | 0.7 Ω (TLP, IR = 10 A) - ensures rapid voltage collapse during sub-100 ns ESD pulses, reducing energy delivered to IC. |
| ISO 10605 compliance | 23 kV at C = 150 pF / R = 330 Ω - satisfies OEM-specific ESD test requirements for vehicle harness interfaces. |
Applications
| Automotive CAN-FD Bus Protection | Automotive CAN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed (2–5 Mbps) CAN-FD communication between ADAS ECUs and domain controllers in electric powertrain systems. IC Role / Device Role / Timing Role: ESD transient suppressor placed at connector interface, clamping fast-rising ESD pulses before they reach the CAN-FD transceiver. Use Value: Maintains signal fidelity with 6 pF capacitance and prevents latch-up or gate oxide damage in transceivers rated for ≤36 V absolute maximum. |
Use Scenario: Safeguarding legacy 1 Mbps CAN networks in body control modules exposed to service port ESD events. IC Role / Device Role / Timing Role: Dual-line protector mounted adjacent to OBD-II connector, providing symmetrical clamping on CANH/CANL with common-cathode architecture. Use Value: Eliminates need for two discrete diodes, reduces PCB area by 40%, and ensures matched clamping response across both lines. |
| Automotive FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Shielding FlexRay physical layer (10 Mbps) in chassis control units against ESD from chassis-ground coupling during assembly or maintenance. IC Role / Device Role / Timing Role: High-speed transient absorber placed between FlexRay transceiver and external harness, leveraging low 6 pF capacitance to preserve edge integrity. Use Value: Prevents bit errors caused by ESD-induced common-mode noise due to matched diode capacitance (<0.5% mismatch) and 33 V clamping ceiling. |
Use Scenario: Protecting single-wire SENT (Single Edge Nibble Transmission) sensor outputs in engine bay pressure/temperature sensors. IC Role / Device Role / Timing Role: Unidirectional clamp on SENT signal line referenced to chassis ground, using pin 1–3 path with 24 V VRWM to tolerate load-dump transients. Use Value: Ensures SENT timing accuracy by limiting clamping overshoot to ≤33 V, avoiding false nibble detection or pulse-width distortion. |
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 | 22 V VRWM, 12 pF capacitance, 30 kV IEC 61000-4-2, SOT-23 package | Higher capacitance limits use to ≤1 Mbps CAN; better ESD rating but lower voltage margin | Select when higher ESD immunity is prioritized over CAN-FD speed support. |
| Vishay VEML6030X01 | 24 V VRWM, 5.5 pF, 15 kV IEC 61000-4-2, AEC-Q101, SOT-23 | Lower ESD rating restricts use to interior modules; identical capacitance and thermal rating | Select when cost sensitivity outweighs requirement for full 23 kV exterior-harness protection. |
Compared with NUF2221MUTAG and VEML6030X01, PESD2CANFD24V-TR uniquely balances 23 kV ESD immunity, 6 pF capacitance, and 24 V standoff to support CAN-FD's 5 Mbps operation in under-hood environments-making it optimal for next-gen automotive serial bus protection where speed, ruggedness, and space constraints coexist.

FAQ
What is the maximum peak pulse current rating for PESD2CANFD24V-TR?
The rated peak pulse current (IPPM) is 2.6 A under 8/20 µs waveform per IEC 61000-4-5. This value is measured from either pin 1 or pin 2 to pin 3 and defines the maximum non-repetitive surge the device can safely clamp without degradation. It aligns with Level 3 automotive surge immunity requirements.
Is PESD2CANFD24V-TR compatible with both CAN and CAN-FD physical layers?
Yes - its 6 pF capacitance, 24 V VRWM, and 33 V clamping voltage meet signal integrity and voltage margin requirements for both 1 Mbps CAN and 5 Mbps CAN-FD. The matched diode capacitance (<0.5% difference between channels) ensures balanced differential mode protection critical for high-speed bus timing.
How does the common cathode (pin 3) configuration affect PCB layout?
Pin 3 serves as the shared low-impedance return path for both protected lines. Layout best practice requires routing pin 3 directly to a solid ground plane with minimal trace length and no vias - ensuring symmetrical transient current paths and preventing ground bounce that could unbalance clamping between CANH and CANL.
Does PESD2CANFD24V-TR require external biasing or control signals?
No - it is a passive, unidirectional TVS diode array requiring no power, enable pins, or configuration. It operates solely via avalanche breakdown above VRWM and conducts only during overvoltage transients, making it inherently fail-safe and compatible with all CAN transceivers without signal conditioning or firmware changes.
