Product details
Overview
PESD2CANFD24L-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 features 24 V reverse standoff voltage, 30 V clamping at 1 A, 10 pF capacitance, 30 kV IEC 61000-4-2 ESD rating, and AEC-Q101 qualification for under-hood vehicle networks.
For engineers reviewing the PESD2CANFD24L-TR datasheet, PESD2CANFD24L-TR pinout, PESD2CANFD24L-TR application, or PESD2CANFD24L-TR equivalent, this device supports high-speed, low-capacitance ESD protection with common-cathode dual-diode topology optimized for CAN-FD signal integrity and thermal robustness up to 175 °C junction temperature.
Technical Context
This device implements a dual-common-cathode TVS diode architecture where pins 1 (K1) and 2 (K2) serve as independent cathodes for two protected lines, while pin 3 (CC) provides shared cathode connection to ground. Its bidirectional clamping behavior enables symmetric surge suppression on differential bus pairs without polarity constraints.
Designed specifically for automotive serial bus protection, it meets ISO 10605 (150 pF/330 Ω) and IEC 61000-4-2 ESD standards, with verified clamping performance across ±8 kV contact discharge pulses and 4 A 8/20 µs surge current capability per line - all validated under AEC-Q101 stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN-FD bus operation (±2.5 V differential, ~12 V common-mode), preserving signal integrity. |
| Clamping Voltage | 30 V at 1 A - Limits transient overvoltage to safe levels for CAN transceivers rated ≤ 36 V absolute maximum. |
| Diode Capacitance | 10 pF - Minimizes signal distortion and timing skew on high-speed CAN-FD buses up to 5 Mbps. |
| ESD Rating | 30 kV (IEC 61000-4-2, contact) - Withstands repeated ESD events without degradation in automotive assembly and service environments. |
| Junction Temperature | 175 °C - Supports placement near heat sources (e.g., powertrain ECUs) without derating or thermal shutdown. |
| Peak Pulse Current | 4 A (8/20 µs) - Handles combined ESD + electrical fast transient (EFT) energy surges per IEC 61000-4-5 Level 3. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 × 1.3 × 1.0 mm body, optimized for automated placement and reflow soldering on dense automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms one half of dual-diode clamp to common cathode. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); enables independent but coordinated clamping with K1. |
| 3 | CC (Common Cathode) | Shared cathode node tied to system ground; defines reference for bidirectional clamping action on both lines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line ESD protection | Single SOT23 device protects two independent bus lines (e.g., CANH/CANL), reducing board area vs. discrete diodes. |
| Ultra-low capacitance matching | 9–10 pF typical with <0.5% ∆Cd/Cd - ensures matched signal delay and common-mode rejection on differential pairs. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD stress - eliminates need for additional qualification testing. |
| High-temperature operation | Rated for continuous operation at Tj = 175 °C - compatible with engine bay and transmission control module placements. |
Applications
| Automotive CAN-FD Networks | Automotive CAN Bus Systems |
|---|---|
|
Use Scenario: High-speed communication between ADAS domain controllers and radar sensors operating at 2–5 Mbps. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector interface to prevent latch-up or damage to CAN-FD transceivers. Use Value: 10 pF capacitance avoids signal rise-time degradation; 30 V clamping prevents transceiver overvoltage beyond its 36 V abs-max rating. |
Use Scenario: Body control module (BCM) communication with door modules and lighting nodes over legacy CAN. IC Role / Device Role / Timing Role: Dual-line protector mounted adjacent to CAN transceiver input pins to shunt ESD energy before entering IC bond wires. Use Value: Common-cathode configuration simplifies grounding layout and reduces PCB trace inductance in return path. |
| FlexRay Communication Buses | SENT Sensor Interfaces |
|
Use Scenario: Powertrain control units exchanging deterministic time-triggered messages at 10 Mbps. IC Role / Device Role / Timing Role: Transient voltage suppressor on FlexRay A/B differential pair, leveraging same 24 V standoff and low capacitance. Use Value: Matches FlexRay's 2.5–3.0 V common-mode range while maintaining >100 MHz bandwidth due to sub-10 pF loading. |
Use Scenario: Engine knock sensor or pressure sensor transmitting single-edge nibble transmission signals to ECU. IC Role / Device Role / Timing Role: Point-of-entry protection on SENT data line, where fast edge rates (≤50 ns) demand minimal capacitive loading. Use Value: 10 pF capacitance introduces <0.5 ns timing jitter - within SENT specification tolerance for 125 kHz base clock. |
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 |
|---|---|---|---|
| NUP2114MR6T1G | 2-channel, 24 V VRWM, 33 V VCL at 1 A, 15 pF capacitance, SOT-23 package, AEC-Q101 qualified. | Higher capacitance limits use in CAN-FD >2 Mbps; suitable for legacy CAN and LIN only. | Select when cost sensitivity outweighs speed requirements and board space allows minor layout adjustment. |
| TPD2E001DRYR | 2-channel, 5 V VRWM, 12 V VCL at 1 A, 3.5 pF capacitance, SOT-553 package, not AEC-Q101 qualified. | Lower standoff voltage restricts to low-voltage buses (e.g., USB, I²C); unsuitable for 12 V automotive supply domains. | Choose only for non-automotive, low-voltage, ultra-high-speed interfaces where AEC qualification is unnecessary. |
Compared with NUP2114MR6T1G and TPD2E001DRYR, PESD2CANFD24L-TR uniquely balances 24 V standoff, 10 pF capacitance, and full AEC-Q101 compliance - making it the only option qualified for CAN-FD in harsh under-hood environments without signal integrity trade-offs.

FAQ
What is the maximum peak pulse current rating for PESD2CANFD24L-TR?
The device is rated for 4 A peak pulse current under 8/20 µs waveform per IEC 61000-4-5, measured from either pin 1 or pin 2 to pin 3. This rating applies at 25 °C ambient and is derated linearly above 25 °C based on thermal resistance and junction temperature limits up to 175 °C.
Can PESD2CANFD24L-TR protect both CAN-H and CAN-L simultaneously?
Yes - its dual-cathode topology (pins 1 and 2) with shared common cathode (pin 3) enables simultaneous, independent clamping of both CAN-H and CAN-L lines to ground. Each channel operates bidirectionally, suppressing positive and negative transients on its respective line without cross-talk.
Is the 10 pF capacitance specified at zero bias or operating voltage?
The 10 pF typical capacitance is measured at 1 MHz with 0 V DC reverse bias across each diode (pin 1–3 and pin 2–3), per Table 6 in the datasheet. Capacitance decreases slightly with increasing reverse voltage, remaining below 10 pF up to 24 V VRWM - critical for maintaining CAN-FD signal fidelity.
Does PESD2CANFD24L-TR require external series impedance for optimal protection?
No external series resistor is required for basic ESD protection, as the device relies on low dynamic resistance (<0.5 Ω) and fast response (<1 ns). However, a small ferrite bead or 0 Ω resistor may be added in series for enhanced filtering of high-frequency EFT noise - layout proximity to the connector remains more critical than added impedance.
