Product details
Overview
PESD2CANFD36UQB-Q from Nexperia is a bidirectional ESD protection diode in DFN1110D-3 (SOT8015) package, designed for dual-line CAN-FD bus protection in automotive systems. It delivers 36 V reverse standoff voltage, 44 V typical clamping at 1 A, and 4.3 pF capacitance - enabling low-distortion signal integrity on high-speed 2 Mbps+ CAN-FD lines while meeting AEC-Q101 qualification.
For engineers reviewing the PESD2CANFD36UQB-Q datasheet, PESD2CANFD36UQB-Q pinout, PESD2CANFD36UQB-Q application, or PESD2CANFD36UQB-Q equivalent, key selection criteria include clamping performance under ISO 10605/IEC 61000-4-2 stress, matched diode capacitance (<0.5% ΔCd), and side-wettable flank (SWF) compatibility with automated optical inspection (AOI) in automotive PCB assembly.
Technical Context
This device implements a dual-cathode, common-cathode topology with two independent ESD protection paths (Pin 1→3 and Pin 2→3), each rated for 12 kV contact discharge per IEC 61000-4-2 and ISO 10605. Its ultra-low dynamic resistance (2.2 Ω) ensures rapid transient energy shunting during sub-nanosecond ESD events.
It supports bidirectional transient suppression across CANH/CANL lines without polarity constraints, with clamping voltage specified at both 1 A (44 V typ.) and 16 A (65 V typ.) using TLP testing per ANSI/ESD STM5.5.1-2008 - critical for maintaining bus differential voltage margins during surge events per ISO 7637-2 Pulse 3a/3b (±300 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - Ensures no conduction during normal 24 V truck/CAN-FD bus operation with margin against ripple and transients. |
| Clamping Voltage (1 A) | 44 V typ. - Limits peak voltage seen by CAN transceiver I/O during ESD, preserving ±30 V absolute max rating compliance. |
| Diode Capacitance | 4.3 pF - Minimizes signal rise-time degradation on >2 Mbps CAN-FD buses; matched within ±0.5% between channels. |
| ESD Rating | 12 kV (IEC 61000-4-2 & ISO 10605) - Meets automotive OEM requirements for connector-level ESD immunity. |
| Peak Pulse Current | 1.6 A (8/20 µs) - Handles ISO 7637-2 Pulse 2a (50 V) and Pulse 3a/3b (±300 V) without failure. |
| Junction Temperature | 150 °C max - Supports under-hood placement in engine control units and body domain controllers. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package (1.1 mm × 1.0 mm × 0.48 mm) with side-wettable flanks for AOI-compatible reflow soldering and thermal reliability in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms one ESD path to common cathode. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); forms second independent ESD path to common cathode. |
| 3 | CC (Common Cathode) | Shared return node tied to chassis or local ground plane; enables compact dual-line layout with single-point transient sink. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low clamping voltage | 44 V @ 1 A - Reduces stress on downstream CAN transceivers during ESD, extending system-level robustness beyond ISO 11898-2 limits. |
| Matched diode capacitance | ΔCd ≤ 0.5% - Preserves differential signal symmetry on CANH/CANL, minimizing common-mode conversion and EMC emissions. |
| AEC-Q101 qualified | Qualified to -55 °C to +150 °C ambient - Validated for permanent installation in powertrain, ADAS, and body control modules. |
| Side-wettable flanks | SOT8015 outline with 0.02 mm max flank protrusion - Enables automated solder-joint inspection (AOI) without X-ray, reducing automotive manufacturing test cost. |
Applications
| CAN-FD Bus Protection | FlexRay Network Protection |
|---|---|
|
Use Scenario: High-speed in-vehicle communication between ADAS ECUs and central gateway over 5 Mbps CAN-FD physical layer. IC Role / Device Role / Timing Role: Dual-line transient suppressor placed directly at connector interface to clamp ESD before reaching CAN transceiver input pins. Use Value: Maintains <2 ns skew between CANH/CANL clamping edges due to matched Cd and Rdyn, preventing bit errors during fast edge transitions. |
Use Scenario: FlexRay bus termination in chassis domain controllers where EMI immunity and deterministic timing are critical. IC Role / Device Role / Timing Role: Bidirectional ESD clamp on FlexRay A/B differential pair, referenced to local ground plane via CC pin. Use Value: 4.3 pF capacitance avoids degrading 10 MHz FlexRay clock harmonics, supporting <100 ns jitter budgets in time-triggered protocols. |
| 24 V Truck CAN Systems | SENT Sensor Interface Protection |
|
Use Scenario: CAN network in heavy-duty commercial vehicles operating at 24 V nominal with wide load-dump transients. IC Role / Device Role / Timing Role: Primary ESD barrier on CANH/CANL lines upstream of isolated bus transceivers in cab-mounted telematics units. Use Value: Withstands ISO 7637-2 Pulse 2a (50 V) and Pulse 3a/3b (±300 V) while maintaining VRWM margin above 24 V rail peaks. |
Use Scenario: Single-wire SENT (SAE J2716) sensor interface in engine control modules exposed to harness-level ESD. IC Role / Device Role / Timing Role: Unidirectional-capable clamp (via K1–CC or K2–CC path) protecting SENT output driver against connector discharge. Use Value: Low leakage (<50 nA @ 36 V) prevents DC offset on SENT current loop, ensuring accurate 12-bit pulse-width encoded sensor data. |
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 |
|---|---|---|---|
| ESDALC6V1-1M2 | Unidirectional; 6.1 V VRWM; higher Cd = 15 pF | Requires external biasing for CAN-FD; unsuitable for >1 Mbps due to capacitance | Select only for 5 V logic-level interfaces with lower speed requirements |
| TPD2E001DRYR | Single-channel; 5.5 V VRWM; 12 pF Cd; non-AEC-Q101 | Lacks dual-line integration and automotive qualification; requires two devices per CAN pair | Use only in non-automotive industrial CAN nodes with relaxed reliability requirements |
Compared with ESDALC6V1-1M2 and TPD2E001DRYR, PESD2CANFD36UQB-Q uniquely combines AEC-Q101 qualification, matched 4.3 pF capacitance, and integrated dual-cathode architecture - enabling single-device, high-speed, automotive-grade CAN-FD protection without layout compromise or derating.

FAQ
What is the maximum operating temperature for PESD2CANFD36UQB-Q?
The device is rated for junction temperatures up to 150 °C and ambient temperatures from −55 °C to +150 °C, validated per AEC-Q101 stress tests including high-temperature operating life and temperature cycling. This supports direct mounting near heat-generating components in engine bay or powertrain ECUs without derating.
Can PESD2CANFD36UQB-Q protect both CANH and CANL simultaneously?
Yes - its dual-cathode, common-cathode configuration provides two independent ESD paths: Pin 1 (K1) to Pin 3 (CC) protects one line (e.g., CANH), and Pin 2 (K2) to Pin 3 (CC) protects the other (e.g., CANL). Both paths share the same clamping threshold and capacitance, ensuring symmetrical transient response.
Is the 4.3 pF capacitance measured differentially or line-to-ground?
The 4.3 pF value is measured line-to-ground (Pin 1 to Pin 3, and Pin 2 to Pin 3) at 1 MHz and 2.5 V reverse bias. The matching specification (ΔCd ≤ 0.5%) confirms that the capacitance difference between the two channels is tightly controlled - critical for maintaining differential signal integrity on CAN-FD buses.
Does PESD2CANFD36UQB-Q require a dedicated ground plane connection?
Yes - Pin 3 (CC) must be connected to a low-inductance ground reference, preferably a solid chassis or local ground plane adjacent to the protected connector. Layout guidelines specify minimizing the trace length from CC to ground and avoiding shared return paths to prevent transient coupling into adjacent circuits.
