Product details
Overview
PESD2CANFD36VQC-QZ from Nexperia is a bidirectional ESD protection diode in DFN1412D-3 (SOT8009) package, designed for dual-line CAN-FD bus protection in automotive 24 V systems. It delivers VRWM = 36 V, typical clamping voltage VCL = 43 V at 1 A, and ultra-low capacitance Cd = 6 pF, enabling high-speed signal integrity while meeting ISO 10605 (20 kV) and AEC-Q101 requirements.
For engineers reviewing the PESD2CANFD36VQC-QZ datasheet, PESD2CANFD36VQC-QZ pinout, PESD2CANFD36VQC-QZ application, or PESD2CANFD36VQC-QZ equivalent, this device addresses critical ESD robustness, low transient impedance, and CAN-FD timing compliance in space-constrained automotive PCB layouts.
Technical Context
This dual-cathode, common-cathode ESD array integrates two matched TVS diodes sharing a single cathode terminal (Pin 3), enabling symmetrical bidirectional clamping on two independent lines (Pins 1 & 2). Its architecture supports differential-mode transient suppression without ground reference dependency.
Designed specifically for CAN-FD physical layer protection, it meets ISO 7637-2 Pulse 2a (55 V), Pulse 3a/3b (±300 V), and IEC 61000-4-5 surge immunity up to 2.3 A (8/20 µs), with dynamic resistance Rdyn = 1.3 Ω ensuring rapid voltage collapse during ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V reverse standoff voltage - maintains signal integrity up to rated bus voltage without leakage or conduction. |
| VCL @ 1 A | 43 V typical clamping voltage - limits transient overvoltage to safe levels for CAN transceivers during ESD contact discharge. |
| Cd | 6 pF diode capacitance - minimizes signal distortion and timing skew on CAN-FD buses operating up to 5 Mbps. |
| ESD Rating | 20 kV per IEC 61000-4-2 and ISO 10605 - certified protection against human-body-model and automotive-specific ESD stress. |
| IPP | 2.3 A peak pulse current (8/20 µs) - withstands ISO 7637-2 surges and load-dump-induced transients in 24 V truck systems. |
| Rdyn | 1.3 Ω dynamic resistance - ensures fast, low-impedance clamping response to sub-nanosecond ESD pulses. |
Pinout & Package
DFN1412D-3 (SOT8009) ultra-small leadless package: 1.4 mm × 1.2 mm × 0.48 mm body, 0.8 mm pitch, side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line (e.g., CANH); reverse-biased during positive transients on that line. |
| 2 | K2 (cathode of diode 2) | Connects to second protected line (e.g., CANL); enables independent clamping for differential bus protection. |
| 3 | CC (common cathode) | Shared cathode node tied to system ground; establishes common reference for bidirectional clamping action on both lines. |
Key Features
| Feature | Design Value |
|---|---|
| Matched diode capacitance | ΔCd/Cd ≤ 0.5% - preserves differential signal balance and common-mode rejection on CAN-FD pairs. |
| Side-wettable flanks | SOT8009 package geometry - enables reliable AOI and X-ray inspection of solder fillets in automotive production. |
| AEC-Q101 qualification | Qualified for automotive use - validated across -55 °C to +150 °C junction temperature range with life-test reliability. |
| Low IRM leakage | 1 nA max at VRWM = 36 V - prevents DC loading or bias shift on high-impedance CAN bus receivers. |
Applications
| Automotive CAN-FD Bus Protection | 24 V Truck Network Protection |
|---|---|
|
Use Scenario: ESD protection at OBD-II connector interface on CAN-FD ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Dual-line transient voltage suppressor placed directly at connector entry point to clamp ±20 kV ESD before reaching transceiver. Use Value: Prevents latch-up or permanent damage to CAN FD transceivers (e.g., TJA1044GK) while maintaining <1 ns response time and <6 pF loading. |
Use Scenario: Surge and ESD protection on chassis-ground-referenced CAN networks in heavy-duty trucks. IC Role / Device Role / Timing Role: Bidirectional clamping element compliant with ISO 7637-2 Pulse 2a (55 V) and Pulse 3a/3b (±300 V) test profiles. Use Value: Enables robust operation in 24 V board nets where load dump and alternator switching induce high-energy transients beyond standard 12 V automotive specs. |
| FlexRay Physical Layer Protection | SENT Sensor Interface Protection |
|
Use Scenario: Transient suppression on FlexRay A/B differential channels in ADAS domain controllers. IC Role / Device Role / Timing Role: Low-capacitance ESD array preserving signal fidelity up to 10 Mbps FlexRay data rates. Use Value: Maintains channel-to-channel capacitance matching (ΔCd ≤ 0.5%) to minimize skew and jitter in deterministic time-triggered networks. |
Use Scenario: ESD hardening of SENT (Single Edge Nibble Transmission) sensor inputs in engine control modules. IC Role / Device Role / Timing Role: High-speed clamping device protecting 125 kHz–3 MHz digital sensor signals from assembly-line ESD events. Use Value: 6 pF capacitance avoids pulse-width distortion in SENT nibble encoding, ensuring accurate air-fuel ratio and knock detection. |
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 |
|---|---|---|---|
| ESD56081D05 | Higher VRWM = 40 V; higher Cd = 12 pF; same SOT8009 footprint. | Better suited for 48 V mild-hybrid architectures but degrades CAN-FD timing margin due to doubled capacitance. | Select only if system operates above 36 V nominal or requires extended surge headroom beyond ISO 7637-2 Pulse 3b. |
| TPD2E007DRYR | Lower VRWM = 5.5 V; lower VCL = 14 V; 3.5 pF Cd; SOT-563 package (larger, non-SWF). | Targeted at 5 V logic-level interfaces; incompatible with 24 V CAN bus due to premature conduction at <36 V. | Not suitable for CAN-FD or truck systems; consider only for low-voltage sensor or infotainment I/O protection. |
Compared with ESD56081D05 and TPD2E007DRYR, PESD2CANFD36VQC-QZ uniquely balances 36 V standoff, 6 pF capacitance, and AEC-Q101 qualification for CAN-FD-making it the only option that satisfies simultaneous high-voltage tolerance, high-speed signal integrity, and automotive production traceability.

FAQ
What is the maximum junction temperature rating for PESD2CANFD36VQC-QZ?
The absolute maximum junction temperature is 150 °C, verified under AEC-Q101 stress testing including high-temperature operating life (HTOL) and temperature cycling. This allows continuous operation in under-hood environments where ambient temperatures reach 125 °C and power dissipation remains negligible due to its passive clamping behavior.
Can PESD2CANFD36VQC-QZ protect both CANH and CANL simultaneously in a single device?
Yes-its dual-cathode, common-cathode topology (Pins 1 & 2 as independent cathodes, Pin 3 as shared cathode) enables true differential-line protection. Each line clamps independently to ground during positive or negative transients, preserving CAN bus common-mode voltage range while suppressing ESD on both conductors.
Is side-wettable flank (SWF) solder joint inspection supported for this package?
Yes-the DFN1412D-3 (SOT8009) package features side-wettable flanks with controlled 0.02 mm max protrusion, enabling reliable automated optical inspection (AOI) of solder fillets. This meets IPC-A-610 Class 3 requirements for automotive electronics manufacturing and supports zero-defect soldering validation.
Does PESD2CANFD36VQC-QZ meet ISO 10605 for both 330 pF/330 Ω and 150 pF/330 Ω test configurations?
Yes-it achieves 20 kV ESD immunity under both ISO 10605 contact discharge conditions: C = 330 pF/R = 330 Ω and C = 150 pF/R = 330 Ω. This dual-certification ensures robustness across global automotive OEM test specifications, including those used by Ford, GM, and Stellantis.
