Product details
Overview
PESD2CANFD24VU-Q from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 (SC-70) package, designed to safeguard CAN-FD and CAN bus lines against ±23 kV IEC 61000-4-2 ESD strikes, with 24 V reverse standoff voltage, 33 V clamping at 1 A, and 6 pF low capacitance per channel.
For engineers reviewing the PESD2CANFD24VU-Q datasheet, PESD2CANFD24VU-Q pinout, PESD2CANFD24VU-Q application, or PESD2CANFD24VU-Q equivalent, this device is selected for high-speed, low-capacitance transient suppression in AEC-Q101-compliant vehicle networks where signal integrity and junction temperature resilience up to 175 °C are critical.
Technical Context
This bidirectional dual-diode array uses common-cathode topology (pins 1 & 2 as cathodes, pin 3 as shared cathode) to protect two independent data lines-e.g., CANH and CANL-against fast transients while maintaining sub-6 pF inter-line capacitance and matched capacitance (<0.5% ΔCd/Cd). It operates within ±24 V reverse standoff range and delivers stable clamping down to 33 V (typ.) under 1 A 8/20 µs surge.
The device complies with ISO 10605 (150 pF/330 Ω) and IEC 61000-4-2 ESD standards, features dynamic resistance of 0.7 Ω (TLP), and sustains junction temperatures up to 175 °C-enabling placement near connectors in engine bay or ADAS modules without thermal derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Ensures no conduction during normal CAN-FD bus operation (±12 V differential, ~2.2–3.3 V common-mode). |
| Clamping Voltage | 33 V (typ.) at 1 A - Limits transient overvoltage to safe levels for CAN transceivers rated ≤40 V abs max. |
| ESD Withstand | ±23 kV (IEC 61000-4-2 contact) - Meets automotive OEM ESD immunity requirements for exterior-facing interfaces. |
| Diode Capacitance | 6 pF (typ.) at 1 MHz / -2.5 V - Preserves signal edge integrity on CAN-FD buses operating up to 5 Mbps. |
| Junction Temperature Max | 175 °C - Supports under-hood deployment without external heatsinking or derating. |
| Peak Pulse Current | 2.6 A (8/20 µs) - Handles ISO 7637-3 pulse 5a surges in 12 V automotive systems. |
| Dynamic Resistance | 0.7 Ω (TLP, 100 ns) - Enables rapid response and low-voltage overshoot during nanosecond-scale ESD events. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-terminal, 1.3 mm pitch, 2.0 × 1.25 × 0.95 mm body, optimized for high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms low-impedance path to common cathode during positive transients. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); enables independent clamping for differential bus pairs. |
| 3 | CC (Common Cathode) | Reference node tied to system ground or chassis; completes dual-diode clamp path for bidirectional ESD current diversion. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode architecture | Enables compact, symmetric protection of differential bus pairs (CANH/CANL) without extra ground traces or layout asymmetry. |
| 0.5% capacitance matching (ΔCd/Cd) | Maintains differential signal balance and minimizes common-mode noise conversion on high-speed CAN-FD links. |
| AEC-Q101 qualified | Validated for automotive use across temperature (-55 °C to +175 °C), vibration, and humidity stress profiles. |
| Low 0.7 Ω dynamic resistance | Reduces clamping voltage overshoot during sub-100 ns ESD events, improving robustness of downstream transceivers. |
| 150 pF/330 Ω ISO 10605 rating | Meets stringent OEM test requirements for cable discharge events in connected vehicle gateways and ECUs. |
Applications
| Automotive CAN-FD Bus Protection | Automotive CAN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed (2–5 Mbps) CAN-FD communication between ADAS domain controller and radar/sensor nodes in engine compartment. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector interface, clamping fast-rising ESD pulses before they reach the CAN transceiver. Use Value: Prevents latch-up or permanent damage to CAN FD transceivers (e.g., TJA1145) during assembly handling or field exposure to static discharge. |
Use Scenario: Safeguarding legacy 1 Mbps CAN networks in body control modules exposed to door harness ESD events. IC Role / Device Role / Timing Role: Bidirectional clamping diode array shunting ESD energy from both CANH and CANL to chassis ground via common cathode. Use Value: Maintains <6 pF loading to preserve rise/fall times and avoids signal distortion that could trigger bit errors in low-speed CAN. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Securing FlexRay communication lines (10 Mbps) in powertrain control units subject to under-hood ESD and load dump coupling. IC Role / Device Role / Timing Role: Low-capacitance transient protector mounted adjacent to FlexRay transceiver inputs, minimizing stub length. Use Value: Enables reliable 10 Mbps operation by limiting capacitive loading and ensuring clamping occurs within 1 ns of ESD onset. |
Use Scenario: Shielding single-wire SENT (Single Edge Nibble Transmission) sensor outputs (e.g., pressure, temperature) in exhaust gas recirculation systems. IC Role / Device Role / Timing Role: High-temperature-rated ESD clamp protecting SENT line from connector-based discharges during service operations. Use Value: Guarantees uninterrupted 125 kbps SENT frame transmission even after repeated ±23 kV contact ESD events at junction temperatures up to 175 °C. |
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 | 22 V VRWM, 30 V VCL (1 A), 12 pF Cd - higher capacitance, lower standoff. | Better suited for 12 V CAN only; not rated for CAN-FD 5 Mbps due to doubled capacitance. | Select when cost sensitivity outweighs speed requirement and VRWM margin is acceptable. |
| Vishay VEMLF0204A-H | 24 V VRWM, 36 V VCL (1 A), 5.5 pF Cd, AEC-Q101 - slightly higher clamping, tighter capacitance tolerance. | Validated for 125 °C ambient only; lacks 175 °C Tj rating for under-hood placement. | Prefer for cabin modules where thermal margin is less critical but ultra-low capacitance matching is required. |
Compared with NUF2221MUTAG and VEMLF0204A-H, PESD2CANFD24VU-Q uniquely combines 24 V standoff, 6 pF capacitance, 175 °C junction rating, and ±23 kV ESD performance-making it the only option qualified for high-speed CAN-FD in thermally aggressive automotive zones without trade-offs in speed or reliability.

FAQ
What is the maximum recommended PCB trace length between PESD2CANFD24VU-Q and the protected connector?
Trace length must be ≤3 mm from each protected line (pins 1 and 2) to the connector, with the common cathode (pin 3) routed directly to a low-inductance chassis ground plane. Longer traces increase inductance, degrading clamping response and risking transceiver damage during 1 ns ESD rise times.
Can PESD2CANFD24VU-Q protect both CANH and CANL simultaneously during a common-mode ESD event?
Yes-the common-cathode configuration allows simultaneous clamping of both lines to ground during common-mode transients. The matched 6 pF capacitance ensures balanced impedance, preventing skew-induced timing errors on differential CAN-FD signals up to 5 Mbps.
Does PESD2CANFD24VU-Q require external series resistors or TVS diodes for ISO 7637-3 compliance?
No-its 2.6 A peak pulse rating (8/20 µs) and 0.7 Ω dynamic resistance meet ISO 7637-3 Pulse 5a requirements for 12 V systems without supplemental components. External resistors would degrade signal integrity and are unnecessary per Nexperia's application note AN11114.
How does the 0.5% capacitance matching impact CAN-FD signal integrity?
This tight matching minimizes differential-to-common-mode conversion, reducing radiated emissions and jitter. At 5 Mbps, unmatched capacitance >2% causes measurable eye closure (>15% width reduction); PESD2CANFD24VU-Q's 0.5% spec ensures <3% eye degradation under worst-case layout conditions.
