Product details
Overview
PESD2CANFD36UU-QF from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT323 package, designed to safeguard CAN-FD and FlexRay bus lines against ±15 kV IEC 61000-4-2 ESD events, with 36 V reverse standoff voltage, 4.3 pF capacitance, and 65 V clamping at 16 A TLP pulse - deployed at vehicle ECUs and gateway modules.
For engineers reviewing the PESD2CANFD36UU-QF datasheet, PESD2CANFD36UU-QF pinout, PESD2CANFD36UU-QF application, or PESD2CANFD36UU-QF equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification, low capacitance for high-speed bus integrity, and common-cathode dual-diode topology for compact two-line protection.
Technical Context
This device implements a dual unidirectional TVS configuration with shared cathode (Pin 3), enabling independent protection of two differential bus lines (e.g., CANH/CANL) while minimizing PCB footprint. Its 36 V VRWM ensures compatibility with 24 V automotive board nets without leakage-induced signal distortion.
Clamping is characterized using both 8/20 µs surge (VCL = 48 V @ 1 A) and 100 ns TLP (VCL = 65 V @ 16 A), with dynamic resistance of 1.3 Ω confirming fast transient response. Capacitance matching (ΔCd/Cd ≤ 0.5%) supports balanced signal integrity across protected pairs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 36 V - Ensures no conduction during normal 24 V board net operation; avoids false triggering on transients below system operating voltage. |
| Clamping Voltage (VCL) | 65 V @ 16 A TLP - Limits peak bus-line overvoltage to safe levels for CAN-FD transceivers rated ≤ 70 V absolute max. |
| Diode Capacitance (Cd) | 4.3 pF @ 2.5 V - Preserves signal edge integrity on CAN-FD buses up to 5 Mbps; minimizes reflection and jitter. |
| ESD Withstand | ±15 kV IEC 61000-4-2 contact discharge - Meets automotive OEM ESD immunity requirements for exterior connectors and harness interfaces. |
| AEC-Q101 Qualification | Qualified - Validated for temperature cycling (-55 °C to +150 °C), HTRB, and ESD stress per automotive discrete semiconductor standard. |
| Peak Pulse Current (IPPM) | 1.5 A @ 8/20 µs - Supports IEC 61000-4-5 Level 3 surge immunity (1 kV line-to-ground) when used with appropriate series impedance. |
Pinout & Package
Package: SC-70 (SOT323), 3-lead surface-mount plastic package, 2.0 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Connects to first protected line (e.g., CANH); anode tied internally to common cathode via ESD junction. |
| 2 | K2 (Cathode of Diode 2) | Connects to second protected line (e.g., CANL); enables independent clamping for differential pair. |
| 3 | CC (Common Cathode) | Reference node for both diodes; must be connected to clean chassis or signal ground with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line ESD protection in single SOT323 | Reduces PCB area by >40% vs. two discrete diodes; eliminates layout mismatch between CANH/CANL paths. |
| Low capacitance matching (ΔCd ≤ 0.5%) | Maintains <10 ps skew between protected lines - critical for CAN-FD bit timing accuracy at 5 Mbps. |
| Common-cathode architecture | Enables symmetrical clamping to ground without requiring separate ground returns; simplifies routing and reduces loop inductance. |
| AEC-Q101 qualified | Validated for 150 °C junction temperature, humidity robustness, and mechanical shock - suitable for under-hood ECU placement. |
Applications
| Automotive CAN-FD Gateway | Truck 24 V Board Net Interface |
|---|---|
|
Use Scenario: Protection of high-speed CAN-FD communication between ADAS domain controller and central gateway. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed directly at connector entry point before CAN transceiver input pins. Use Value: Prevents latch-up or damage to ISO 11898-2 transceivers during door-handle or diagnostic port ESD events while preserving 5 Mbps signal fidelity. |

IC Role / Device Role / Timing Role: Dual-line transient suppressor on 24 V-rated CAN and SENT sensor lines exposed to cab harnesses. Use Value: Enables compliance with ISO 10605 (15 kV) without degrading SENT pulse-edge rise time (<100 ns) due to ultra-low 4.3 pF loading. |
| FlexRay Bus Node | Automotive Body Control Module |
|
Use Scenario: Transient protection for FlexRay physical layer in chassis domain controllers requiring deterministic 10 Mbps operation. IC Role / Device Role / Timing Role: Common-cathode dual TVS placed adjacent to FlexRay transceiver RX/TX pins to suppress ESD-induced bit errors. Use Value: Maintains <0.5% duty-cycle distortion on 10 Mbps FlexRay signals while clamping 15 kV discharges to <65 V peak. |
Use Scenario: ESD safeguard for LIN/CAN mixed-bus body electronics in door modules and seat controllers. IC Role / Device Role / Timing Role: Shared-cathode protector applied to both CAN-L and LIN bus lines routed through same connector housing. Use Value: Reduces BOM count by consolidating two protection functions into one SOT323 device without compromising AEC-Q101 reliability. |
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 |
|---|---|---|---|
| ESD5V3U2U-2/TR | Lower VRWM (5.3 V), higher Cd (15 pF), same SOT323 package | Targeted for 3.3 V/5 V data lines (USB, I²C), not 24 V CAN-FD | Select only for low-voltage digital interfaces; unsuitable for 24 V bus protection due to premature conduction. |
| TPD2E001DRYR | 3.3 V VRWM, 10 pF Cd, dual-channel, DRY (SOT-553) package | Designed for portable electronics; lacks AEC-Q101 qualification and automotive thermal rating | Not recommended for automotive deployment; fails junction temperature (150 °C) and ESD test protocol validation. |
Compared with ESD5V3U2U-2/TR and TPD2E001DRYR, PESD2CANFD36UU-QF uniquely combines 36 V standoff, 4.3 pF capacitance, and AEC-Q101 qualification - making it the only option validated for CAN-FD and 24 V truck systems where high-voltage tolerance and low signal distortion are simultaneously required.

FAQ
What is the maximum junction temperature rating for PESD2CANFD36UU-QF?
The device is rated for a maximum junction temperature of 150 °C, verified per AEC-Q101 thermal stress tests including high-temperature reverse bias (HTRB) and temperature cycling. This enables reliable operation in under-hood environments where ambient temperatures reach 125 °C and power dissipation induces additional thermal rise.
Can PESD2CANFD36UU-QF protect both CANH and CANL simultaneously?
Yes - its dual-diode structure with independent cathodes (Pins 1 and 2) and shared cathode (Pin 3) allows simultaneous, symmetrical clamping of both CANH and CANL lines to ground. The matched 4.3 pF capacitance ensures equal signal delay, preserving differential integrity required for CAN-FD bit timing.
Is the 15 kV ESD rating applicable to both contact and air discharge?
The 15 kV rating applies specifically to IEC 61000-4-2 contact discharge testing. Air discharge performance is not specified in the datasheet; design-in should follow OEM requirements specifying contact discharge only, as is standard for automotive connector-level ESD validation.
Does PESD2CANFD36UU-QF require external biasing or control signals?
No - it is a passive, unidirectional TVS diode array with no control pins, supply rails, or enable logic. It operates solely based on voltage threshold conduction: clamping begins above 36 V VRWM and fully engages during ESD transients, requiring zero external circuitry or configuration.
