Product details
Overview
PESD2CANFD36VQB-Q from Nexperia is a bidirectional ESD protection diode in DFN1110D-3 (SOT8015) package, designed for CAN-FD bus line protection in automotive systems. It delivers 36 V reverse standoff voltage, 43 V typical clamping at 1 A, and 6 pF capacitance - enabling low-distortion transient suppression on high-speed differential buses.
For engineers reviewing the PESD2CANFD36VQB-Q datasheet, PESD2CANFD36VQB-Q pinout, PESD2CANFD36VQB-Q application, or PESD2CANFD36VQB-Q equivalent, this device is selected for AEC-Q101-compliant CAN-FD transceiver interface protection where low clamping voltage, tight capacitance matching (<0.5% ΔCd/Cd), and side-wettable flanks for solder joint inspection are critical.
Technical Context
This dual-diode array uses common-cathode configuration (pins 1 & 2 as individual cathodes, pin 3 as shared cathode) to protect two independent signal lines - e.g., CANH and CANL - with matched dynamic impedance (Rdyn = 1.1 Ω) and symmetrical clamping behavior under ±20 kV IEC 61000-4-2 and ISO 10605 stress.
Its ultra-low 6 pF capacitance (measured at 1 MHz, ±2.5 V) and <0.5% inter-channel capacitance matching ensure minimal signal integrity impact on CAN-FD's up to 5 Mbps data rate, while ISO 7637-2 pulse 3a/3b (±300 V) and pulse 2a (55 V) compliance supports robustness against automotive load-dump and inductive switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 36 V - defines maximum continuous operating voltage before leakage rise; ensures compatibility with 24 V truck/bus supply rails. |
| Clamping Voltage (1 A) | 43 V typ - limits peak transient voltage seen by downstream CAN transceiver during ESD events, preserving IC reliability. |
| Diode Capacitance | 6 pF max - maintains signal integrity on CAN-FD differential pairs without degrading edge rate or causing reflections. |
| ESD Rating | ±20 kV IEC 61000-4-2 contact - meets automotive OEM requirements for human-body-model ESD immunity at connector interfaces. |
| ISO 7637-2 Pulse 3a/3b | ±300 V - withstands fast-rising electrical fast transients induced by relay switching and alternator load dumps. |
| Junction Temperature Limit | 150 °C - enables operation in under-hood environments with extended thermal cycling life per AEC-Q101 qualification. |
| Package | DFN1110D-3 (SOT8015) - 1.1 mm × 1.0 mm × 0.48 mm body with side-wettable flanks for automated optical solder-joint inspection. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin plastic package with side-wettable flanks (SWF), 0.65 mm pitch, and 1.1 mm × 1.0 mm footprint - optimized for space-constrained automotive PCB layouts and AOI-compatible reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Connects to first protected line (e.g., CANH); forms anode-to-ground path during positive transients. |
| 2 | K2 (Cathode of Diode 2) | Connects to second protected line (e.g., CANL); provides matched clamping response for differential pair symmetry. |
| 3 | CC (Common Cathode) | Shared cathode node tied to system ground; establishes reference for bidirectional clamping on both signal lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Enables symmetric protection of differential CAN-FD signals without polarity constraints on line routing. |
| Capacitance Matching | ≤0.5% ΔCd/Cd ensures balanced loading on CANH/CANL, minimizing common-mode noise conversion and skew. |
| AEC-Q101 Qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock testing. |
| Side-Wettable Flanks | Facilitates automated X-ray or optical inspection of solder fillets - critical for zero-defect manufacturing in Tier-1 supply chains. |
| Low Dynamic Resistance | 1.1 Ω Rdyn ensures rapid voltage clamping during sub-100 ns ESD pulses, reducing energy dissipation in protected ICs. |
Applications
| Automotive CAN-FD Interface Protection | 24 V Truck Network Bus Protection |
|---|---|
Use Scenario: Protecting CAN-FD transceivers in ADAS domain controllers against connector-level ESD events during service or assembly. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between connector and transceiver pins, with clamping action triggered within nanoseconds of ESD onset. Use Value: Prevents latch-up or gate oxide damage in transceivers by limiting peak voltage to 43 V at 1 A, maintaining >5 Mbps data integrity. |
Use Scenario: Shielding FlexRay or SENT sensor networks in heavy-duty vehicle ECUs from electrostatic discharge in humid cargo bay environments. IC Role / Device Role / Timing Role: Dual-line ESD clamp deployed at harness entry points, leveraging matched capacitance to avoid timing skew across multi-signal bundles. Use Value: Enables reliable operation at 24 V nominal rail with 36 V VRWM margin, supporting ISO 16750-2 load-dump immunity up to 35 V. |
| FlexRay Bus Line Protection | SENT Sensor Interface Protection |
Use Scenario: Safeguarding FlexRay physical layer components in powertrain gateways exposed to repeated ESD during diagnostic port access. IC Role / Device Role / Timing Role: Low-capacitance shunt protector on differential FlexRay A/B lines, referenced to chassis ground via common cathode. Use Value: Maintains 10 Mbps FlexRay signal fidelity with ≤6 pF loading and <0.5% inter-line capacitance mismatch. |
Use Scenario: Securing single-wire SENT communication from crankshaft/camshaft position sensors in engine control modules. IC Role / Device Role / Timing Role: Unidirectional clamp (using K1–CC or K2–CC path) on SENT signal line, suppressing contact-discharge transients before reaching MCU GPIO. Use Value: Limits transient overshoot to ≤43 V during 20 kV ESD strikes, preventing false edge detection and sensor reporting errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1U2 | Lower VRWM (6.1 V), higher Cd (15 pF), same SOT8015 package | Targeted at 5 V logic interfaces, not 24 V/36 V CAN-FD bus lines | Select only for low-voltage digital I/O; unsuitable for CAN-FD due to insufficient standoff and excessive capacitance. |
| TPD2E001DRYR | 3.6 V VRWM, 12 pF Cd, 0.65 mm pitch DRY (SON-6) package | Designed for USB/USB-C and low-speed data lines, not automotive-grade surge immunity | Not AEC-Q101 qualified; lacks ISO 7637-2 pulse 3a/3b rating - invalid for automotive bus protection. |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, PESD2CANFD36VQB-Q uniquely combines 36 V standoff, 6 pF capacitance, ±20 kV ESD rating, and AEC-Q101 qualification - making it the only viable option for CAN-FD and FlexRay bus protection in production automotive ECUs.

FAQ
What is the maximum peak pulse current rating for PESD2CANFD36VQB-Q?
The rated peak pulse current (IPPM) is 2.3 A under 8/20 µs waveform per IEC 61000-4-5. This value applies to each diode path (pin 1→3 or pin 2→3) and reflects the device's ability to absorb transient energy without degradation when used within recommended layout guidelines.
Can PESD2CANFD36VQB-Q be used for single-line protection, or is dual-line use mandatory?
It can protect either one or two lines: using pins 1 and 3 forms one bidirectional clamp; pins 2 and 3 form another. Both paths operate independently with identical specifications. No functional dependency exists between K1 and K2 - they may be used separately or together based on board routing needs.
Does the 6 pF capacitance apply to both diode channels equally?
Yes - the datasheet specifies ≤6 pF for each channel (pin 1–3 and pin 2–3) at 1 MHz and ±2.5 V reverse bias, with capacitance matching guaranteed at ≤0.5% difference (ΔCd/Cd), ensuring balanced loading on differential bus pairs like CANH/CANL.
Is the common cathode (pin 3) required to connect directly to chassis ground?
Pin 3 must connect to a low-impedance ground plane - preferably the same ground used by the protected transceiver - to ensure effective clamping. Routing through long traces or shared return paths increases inductance and degrades clamping performance; direct connection minimizes voltage overshoot during fast transients.
