Product details
Overview
PESD2CANFD36UQC-QZ from Nexperia is a bidirectional ESD protection diode in a DFN1412D-3 (SOT8009) package, designed for CAN-FD bus line protection in automotive systems. It delivers 36 V reverse stand-off voltage, 44 V typical clamping at 1 A, and 4.3 pF capacitance - enabling robust transient suppression without signal integrity degradation on high-speed differential buses.
For engineers reviewing the PESD2CANFD36UQC-QZ datasheet, PESD2CANFD36UQC-QZ pinout, PESD2CANFD36UQC-QZ application, or PESD2CANFD36UQC-QZ equivalent, key selection criteria include low clamping voltage under IEC 61000-4-2/ISO 10605 stress, AEC-Q101 qualification, side-wettable flank compatibility with automated optical inspection (AOI), and matched capacitance (<0.5% ΔCd) across dual channels.
Technical Context
This dual-channel TVS diode uses a common-cathode configuration (pins 1 & 2 as individual cathodes, pin 3 as shared cathode) to protect two independent signal lines - such as CANH and CANL - with matched dynamic impedance and symmetrical clamping behavior. Its design targets fast transient response (TLP-measured VCL = 65 V at 16 A, 100 ns) and minimal parasitic capacitance variation over reverse bias.
The device operates within −55 °C to +150 °C ambient range and supports ISO 7637-2 pulse 2a (50 V), 3a/3b (±300 V), ensuring resilience against load dump and inductive switching transients in 24 V truck networks. Its 0.48 mm profile and 1.4 mm × 1.2 mm footprint meet space-constrained automotive ECU layout requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 36 V - Ensures no conduction during normal CAN-FD bus operation (±30 V common-mode range) |
| Clamping Voltage (1 A) | 44 V typical - Limits peak voltage seen by transceiver during IEC 61000-4-2 contact discharge |
| Diode Capacitance | 4.3 pF at 2.5 V reverse - Preserves signal integrity up to 5 Mbps CAN-FD data rates |
| ESD Rating | 12 kV per IEC 61000-4-2 & ISO 10605 - Meets automotive OEM ESD immunity requirements |
| Peak Pulse Current | 1.6 A (8/20 µs) - Handles repetitive surge events per ISO 7637-2 without degradation |
| Dynamic Resistance | 2.2 Ω - Enables rapid voltage clamping with minimal overshoot during fast transients |
| Capacitance Matching | ≤0.5% ΔCd - Guarantees balanced differential signal attenuation across CANH/CANL paths |
Pinout & Package
DFN1412D-3 (SOT8009) package: ultra-small 1.4 mm × 1.2 mm × 0.48 mm body with side-wettable flanks for AOI-compatible reflow soldering and IPC Class 3 reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms one half of dual-channel TVS pair |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); ensures matched clamping with Pin 1 |
| 3 | CC (Common Cathode) | Shared cathode node tied to system ground; enables compact dual-line protection topology |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress - supports 15-year vehicle lifecycle |
| Side-wettable flanks | Enables automated optical inspection of solder joints on bottom-terminated pins - critical for zero-defect automotive manufacturing |
| Bidirectional clamping | Protects both positive and negative transients on CANH/CANL without polarity constraints - eliminates need for external biasing |
| Matched channel capacitance | ΔCd ≤ 0.5% ensures <1 ps skew between differential paths - preserves CAN-FD timing margins at 5 Mbps |
| Low dynamic resistance | Rdyn = 2.2 Ω minimizes voltage overshoot during sub-100 ns ESD events - reduces transceiver latch-up risk |
Applications
| Automotive CAN-FD Bus Protection | 24 V Truck Network ESD Suppression |

|
Use Scenario: Protecting CAN-FD physical layer in ADAS domain controllers exposed to IEC 61000-4-2 ±15 kV contact discharge during service port access. IC Role / Device Role / Timing Role: Dual-channel transient voltage suppressor placed directly at connector interface to clamp ESD before reaching CAN transceiver. Use Value: 44 V clamping at 1 A prevents transceiver damage while maintaining <5% signal distortion at 5 Mbps due to 4.3 pF capacitance. |
Use Scenario: Safeguarding diagnostic and powertrain CAN lines in heavy-duty trucks operating in −40 °C to +125 °C under ISO 7637-2 pulse 3b (−300 V). IC Role / Device Role / Timing Role: Common-cathode TVS providing symmetric overvoltage protection for both CANH and CANL against load-dump-induced surges. Use Value: 1.6 A peak pulse rating and 150 °C junction temperature rating ensure uninterrupted operation during extended engine cranking events. |
| FlexRay Bus Transient Protection | SENT Sensor Interface Protection |
|
Use Scenario: Shielding FlexRay communication lines in chassis control modules from ESD during assembly and field maintenance. IC Role / Device Role / Timing Role: Low-capacitance dual TVS placed adjacent to FlexRay transceiver inputs to preserve 10 Mbps differential signaling fidelity. Use Value: 4.3 pF capacitance and matched ΔCd ≤ 0.5% limit inter-pair skew to <0.8 ps - meeting FlexRay physical layer jitter budget. |
Use Scenario: Securing SENT (Single Edge Nibble Transmission) sensor outputs in engine control units subjected to factory ESD handling. IC Role / Device Role / Timing Role: Point-of-entry ESD clamp on SENT signal line to prevent latch-up in microcontroller GPIOs during production testing. Use Value: 36 V VRWM avoids leakage current interference with SENT's 5 V supply rail, while 12 kV ESD rating exceeds ISO 10605 test limits. |
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 |
|---|---|---|---|
| ESD56081D05-2/TR | Higher VRWM (40 V), higher capacitance (6.5 pF), no side-wettable flanks | Better suited for 42 V mild-hybrid systems but degrades >2 Mbps signal integrity | Select when higher stand-off voltage is required and AOI is not mandated |
| TPD2E001DRYR | Lower VRWM (5.5 V), lower clamping (12 V), unidirectional, no AEC-Q101 qualification | Targeted at consumer USB/IO protection - unsuitable for automotive CAN-FD | Avoid for automotive use; lacks ISO 10605 rating and thermal robustness |
Compared with ESD56081D05-2/TR and TPD2E001DRYR, PESD2CANFD36UQC-QZ uniquely combines AEC-Q101 qualification, side-wettable flanks, 4.3 pF capacitance, and matched dual-channel performance - making it the only option validated for CAN-FD in production automotive ECUs requiring AOI traceability and 5 Mbps timing compliance.

FAQ
What is the maximum operating temperature for PESD2CANFD36UQC-QZ?
The device supports junction temperatures up to 150 °C and ambient operating ranges from −55 °C to +150 °C, verified per AEC-Q101 thermal cycling and high-temperature reverse bias tests - enabling deployment in under-hood ECUs and transmission control units.
Does PESD2CANFD36UQC-QZ require external biasing for bidirectional protection?
No external biasing is needed. Its common-cathode dual-diode structure provides inherent bidirectional clamping across both protected lines (e.g., CANH and CANL) without additional components - simplifying PCB layout and reducing BOM count.
How does the side-wettable flank design impact manufacturing yield?
The side-wettable flanks enable automated optical inspection (AOI) of solder joint quality on all three terminals - directly addressing automotive zero-defect requirements and improving first-pass yield in reflow processes for high-reliability ECUs.
Can PESD2CANFD36UQC-QZ be used for non-automotive CAN applications?
Yes - its electrical specs (36 V VRWM, 4.3 pF, 12 kV ESD) are applicable to industrial CAN networks, but AEC-Q101 qualification and automotive-specific surge ratings (ISO 7637-2) provide added margin beyond generic CAN requirements.
